Efficacy of fasting and calorie restriction (FCR) on mood and depression among ageing men

Hussin NM, Shahar S, Teng NI, Ngah WZ, Das SK

J Nutr Health Aging, 2013;17(8):674-80.
PMID: 24097021 DOI: 10.1007/s12603-013-0344-9

OBJECTIVE: An intervention study on the FCR (Fasting and Calorie Restriction) dietary regime was carried out to determine its efficacy in improving mood states and depression status among ageing men.
SUBJECTS: A total of 32 healthy males (Mean±SD), aged 59.7±6.3 years, with a BMI of 26.7±2.2 kg/m2 were recruited to the study.
METHOD: Participants were randomized to either the FCR group (and were instructed to follow a calorie restricted dietary regime with intermittent fasting) or to the control group (in which individuals were asked to maintain their current lifestyle), for a 3 month period. Mood was assessed using the Profile of Mood States and depression was assessed using Beck Depression Inventory-II and Geriatric Depression Scale-15 at baseline, week 6 and week 12 of the intervention.
RESULTS: A total of 31 subjects completed the study (n=16, FCR and n=15, control). Significant decreases in tension, anger, confusion and total mood disturbance and improvements in vigor were observed in participants in the FCR group compared to the control group (p<0.05). No significant changes in mean depression scores were observed. Weight, BMI and percent body fat were reduced by 3.8%, 3.7% and 5.7% respectively in the FCR group.
CONCLUSIONS: Our findings show that a FCR dietary regime is effective in improving mood states and nutritional status among ageing men.

The paradox of low body mass index and high body fat percentage among Chinese, Malays and Indians in Singapore

Deurenberg-Yap M, Schmidt G, van Staveren WA, Deurenberg P

Int. J. Obes. Relat. Metab. Disord., 2000 Aug;24(8):1011-7.
PMID: 10951540

OBJECTIVE: To study the relationship between body fat percentage and body mass index (BMI) in three different ethnic groups in Singapore (Chinese, Malays and Indians) in order to evaluate the validity of the BMI cut-off points for obesity.
DESIGN: Cross-sectional study.
SUBJECTS: Two-hundred and ninety-one subjects, purposively selected to ensure adequate representation of range of age and BMI of the general adult population, with almost equal numbers from each ethnic and gender group.
MEASUREMENTS: Body weight, body height, sitting height, wrist and femoral widths, skinfold thicknesses, total body water by deuterium oxide dilution, densitometry with Bodpod(R) and bone mineral content with Hologic(R) QDR-4500. Body fat percentage was calculated using a four-compartment model.
RESULTS: Compared with body fat percentage (BF%) obtained using the reference method, BF% for the Singaporean Chinese, Malays and Indians were under-predicted by BMI, sex and age when an equation developed in a Caucasian population was used. The mean prediction error ranged from 2.7% to 5.6% body fat. The BMI/BF% relationship was also different among the three Singaporean groups, with Indians having the highest BF% and Chinese the lowest for the same BMI. These differences could be ascribed to differences in body build. It was also found that for the same amount of body fat as Caucasians who have a body mass index (BMI) of 30 kg/m2 (cut-off for obesity as defined by WHO), the BMI cut-off points for obesity would have to be about 27 kg/m2 for Chinese and Malays and 26 kg/m2 for Indians.
CONCLUSIONS: The results show that the relationship between BF% and BMI is different between Singaporeans and Caucasians and also among the three ethnic groups in Singapore. If obesity is regarded as an excess of body fat and not as an excess of weight (increased BMI), the cut-off points for obesity in Singapore based on the BMI would need to be lowered. This would have immense public health implications in terms of policy related to obesity prevention and management.

Is a re-evaluation of WHO body mass index cut-off values needed? The case of Asians in Singapore

Deurenberg-Yap M, Deurenberg P

Nutr Rev, 2003 May;61(5 Pt 2):S80-7.
PMID: 12828197

This paper describes body composition and dietary intakes of the three major ethnic groups residing in Singapore and how these are related to cardiovascular risk factors in these groups. When the relationship between body mass index (BMI, kg/m2) and body fat percentage was studied, Singaporeans were found to have higher percentage of body fat compared with Caucasians with the same BMI. At BMIs that are much lower than WHO-recommended cut-off values for obesity, both the absolute and relative risks of developing cardiovascular risk factors are markedly elevated for all three ethnic groups. The excessive fat accumulation and increased risks at lower BMIs signal a need to re-examine cut-off values for obesity among Chinese, Malays, and Indians.

Fulltext Body fat measurement among Singaporean Chinese, Malays and Indians: a comparative study using a four-compartment model and different two-compartment models

Deurenberg-Yap M, Schmidt G, van Staveren WA, Hautvast JG, Deurenberg P

Br J Nutr, 2001 Apr;85(4):491-8.
PMID: 11348564 DOI: 10.1079/bjn2000276

This cross-sectional study compared body fat percentage (BF%) obtained from a four-compartment (4C) model with BF% from hydrometry (using 2H2O), dual-energy X-ray absorptiometry (DXA) and densitometry among the three main ethnic groups (Chinese, Malays and Indians) in Singapore, and determined the suitability of two-compartment (2C) models as surrogate methods for assessing BF% among different ethnic groups. A total of 291 subjects (108 Chinese, seventy-six Malays, 107 Indians) were selected to ensure an adequate representation of age range (18-75 years) and BMI range (16-40 kg/m2) of the general adult population, with almost equal numbers from each gender group. Body weight was measured, together with body height, total body water by 2H2O dilution, densitometry with Bodpod and bone mineral content with Hologic QDR-4500. BF% measurements with a 4C model for the subgroups were: Chinese females 33.5 (sd 7.5), Chinese males 24.4 (sd 6.1), Malay females 37.8 (sd 6.3), Malay males 26.0 (sd 7.6), Indian females 38.2 (sd 7.0), Indian males 28.1 (sd 5.5). Differences between BF% measured by the 4C and 2C models (hydrometry, DXA and densitometry) were found, with underestimation of BF% in all the ethnic-gender groups by DXA of 2.1-4.2 BF% and by densitometry of 0.5-3.2 BF%). On a group level, the differences in BF% between the 4C model and 2H2O were the lowest (0.0-1.4 BF% in the different groups), while differences between the 4C model and DXA were the highest. Differences between the 4C model and 2H2O and between the 4C model and DXA were positively correlated with the 4C model, water fraction (f(water)) of fat-free mass (FFM) and the mineral fraction (f(mineral)) of FFM, and negatively correlated with density of the FFM (D(FFM)), while the difference between 4C model and densitometry correlated with these variables negatively and positively respectively (i.e. the correlations were opposite). The largest contributors to the observed differences were f(water) and D(FFM). When validated against the reference 4C model, 2C models were found to be unsuitable for accurate measurements of BF% at the individual level, owing to the high errors and violation of assumptions of constant hydration of FFM and D(FFM) among the ethnic groups. On a group level, the best 2C model for measuring BF% among Singaporeans was found to be 2H2O.

Validity of body composition methods across ethnic population groups

Deurenberg P, Deurenberg-Yap M

Acta Diabetol, 2003 Oct;40 Suppl 1:S246-9.
PMID: 14618484

Most in vivo body composition methods rely on assumptions that may vary among different population groups as well as within the same population group. The assumptions are based on in vitro body composition (carcass) analyses. The majority of body composition studies were performed on Caucasians and much of the information on validity methods and assumptions were available only for this ethnic group. It is assumed that these assumptions are also valid for other ethnic groups. However, if apparent differences across ethnic groups in body composition 'constants' and body composition 'rules' are not taken into account, biased information on body composition will be the result. This in turn may lead to misclassification of obesity or underweight at an individual as well as a population level. There is a need for more cross-ethnic population studies on body composition. Those studies should be carried out carefully, with adequate methodology and standardization for the obtained information to be valuable.

Comparison of the effectiveness of online and face-to-face weight-loss interventations in the workplace: evidence from Malaysia

Roszanadia Rusali, Zahara Abdul Manaf, Suzana Shahar, Fatin Hanani Mazri, Norhayati Ibrahim, Arimi Fitri Mat Ludin, et al.

Sains Malaysiana, 2018;47:2437-2445.

A structured weight management programme at a workplace may help in reducing the prevalence of overweight and obesity.
Therefore, this intervention study was to determine the effectiveness of weight loss programmes including face-to-face,
online and control group at workplace among employees who are overweight and obese. A total of 108 overweight and
obese adults were recruited and randomly divided into three groups (face-to-face group (FT), n=38; online group (OG),
n=31; control group (CG), n=39). In the FT group, the participants took part in health talks, interactive activities and
counselling; the OG group was given access to an online weight management program and the CG group was provided
with educational booklets on weight loss. All information given was related to nutrition, physical activity and motivation
to reduce weight. Body weight, body mass index (BMI), waist circumference (WC), body fat percentage, dietary intake,
fasting lipid profile and glucose levels were assessed at baseline and 4 months. The FT group showed greater reduction
in body weight (-5.80 kg) compared to OG (-1.12 kg) and CG (-1.82 kg). Significant interaction effects were found for BMI,
WC, fasting serum triglycerides, HDL-cholesterol and total cholesterol/HDL-cholesterol ratio (all p<0.05), with the FT
group showing the biggest improvements, compared to the other groups. The face-to-face weight management program
offered in the workplace showed to be the most effective at improving anthropometric profile, fasting serum triglycerides,
HDL-C, total cholesterol/HDL-C ratio, and dietary intake among overweight and obese employees.

Emerging Role of Adipocytokines in Type 2 Diabetes as Mediators of Insulin Resistance and Cardiovascular Disease

Jaganathan R, Ravindran R, Dhanasekaran S

Can J Diabetes, 2018 Aug;42(4):446-456.e1.
PMID: 29229313 DOI: 10.1016/j.jcjd.2017.10.040

Adipose tissue is an enormously active endocrine organ, secreting various hormones, such as adiponectin, leptin, resistin and visfatin, together with classical cytokines, such as tumor necrosis factor-alpha (TNF-α) and interleukin-6 (IL-6). All these adipocytokines play significant roles in the regulation of energy metabolism, glucose and lipid metabolism, reproduction, cardiovascular function and immunity. Adipocytokines are significantly regulated by nutritional status and can directly influence other organ systems, including brain, liver and skeletal muscle. Adiponectin plays a key role as an anti-inflammatory hormone. Upregulated expression of resistin, vaspin, apelin and TNF-α plays a significant role in induction of insulin resistance linked with obesity and type 2 diabetes. Ghrelin, the circulating peptide, has been found to stimulate appetite and regulate energy balance. Thus, it can be considered 1 of the candidate genes for obesity and type 2 diabetes. Omentin is a novel adipokine produced by visceral adipose tissue. Circulating levels of omentin are decreased in insulin-resistant states, for example, in obesity and diabetes. IL-6 plays a vital role in regulating the accumulation of lipids intramyocardially. Based on the biologic relevance of these adipocytokines, they can no longer be considered as energy storage sites alone but must also be considered in metabolic control. Hence, the present review summarizes the regulatory roles of adipocytokines in diabetes linked with obesity.

Fulltext Nutrition and ecosystems in Sarawak: The role of the areca nut

Strickland SS, Duffield AE

Asia Pac J Clin Nutr, 1998 Dec;7(3/4):300-6.
PMID: 24393688

The effects of population pressure on agricultural sustainability in the delicate tropical and subtropical ecosystems have often been thought to explain high prevalence rates of malnutrition in rural South-East Asia. However, recent studies in rural Sarawak suggest that processes of modernisation have resulted in increased variations in energy nutritional status in adults. A contributory factor may be consumption of the areca nut (Malay pinang, of the palm Areca catechu). This is thought to influence energy balance through effects on appetite and resting metabolic rate. Body mass index (BMI, kg/m2) data for 325 Iban men and 438 non-pregnant Iban women, measured in 1990 and again in 1996, have been analysed in relation to areca use, smoking behaviour, socio-economic status, and reported morbidity. Body composition derived from skinfold thickness measurements for 313 men and 382 women was also analysed. The results suggest that use of areca nut is associated with significantly lower age-related increments in BMI and percentage body fat in women after allowing for age, smoking, reported morbidity, and confounding socio-economic factors. Therefore, the impact of recent economic and social development seen in rising prevalences of 'over-nutrition' may be modulated by use of the areca nut.

Fulltext Effect of brown adipose tissue activation on myocardial fluorine-18-fluorodeoxyglucose uptake

Alenezi SA, Dannoon SF, Alnafisi NS, Asa'ad SM, Osman MM, Elgazzar AH

World J Nucl Med, 2020 01 14;19(1):41-46.
PMID: 32190021 DOI: 10.4103/wjnm.WJNM_16_19

The aim of this study is to investigate the relationship between brown adipose tissue (BAT) activation and myocardial fluorine-18-fluorodeoxyglucose ([18F] FDG) uptake in terms of intensity and patterns. The patients were divided into two groups as follows: BAT and control groups. The BAT group consists of 34 cases that showed BAT uptake. The control group, with no BAT uptake, included 68 patients who were matched for body mass index, gender, and season. The scans were retrospectively reviewed by two nuclear medicine physicians who visually evaluated the intensity of myocardial [18F] FDG uptake. The myocardial [18F] FDG uptake was visually classified into the following three patterns: diffuse, heterogeneous, and focal. The regions of activated BAT distribution were noted. The mean myocardial [18F] FDG uptake was 2.50 ± 0.75 for the BAT group and 2.13 ± 0.88 for the control group with a statistically significant difference (P = 0.031). The myocardial [18F] FDG uptake pattern was similar in the BAT and control groups with the diffuse pattern being the most common, followed by the heterogeneous and less commonly focal. In the BAT group, the anatomical distribution of BAT was mainly in supraclavicular, paravertebral, and axillary and to a lesser extent in cervical regions. BAT group had a significantly higher intensity of [18F] FDG myocardial uptake compared to that of the control group. The presence of activated BAT did not affect the pattern of myocardial uptake. Knowledge of these findings may help in understanding the variability of myocardial [18F] FDG uptake and consequently in avoiding misinterpretation of cardiac findings in positron-emission tomography/computed tomography studies.

Evaluation of physical properties and image of polyvinyl chloride as breast tissue equivalence for dual-modality (mammography and ultrasound)

Hariyanto AP, Budiarti NT, Suprijanto, Ng KH, Haryanto F, Endarko

Phys Eng Sci Med, 2023 Sep;46(3):1175-1185.
PMID: 37253939 DOI: 10.1007/s13246-023-01283-y

TMP is gradually becoming a fundamental element for quality assurance and control in ionizing and non-ionizing radiation imaging modalities as well as in the development of different techniques. This study aimed to evaluate and obtain polyvinyl chloride tissue mimicking material for dual-modality breast phantoms in mammography and ultrasound. Breast tissue equivalence was evaluated based on X-ray attenuation properties, speed of sound, attenuation, and acoustic impedance. There are six samples of PVC-plasticizer material with variations of PVC concentration and additives. The evaluation of X-ray attenuation was carried out using mammography from 23 to 35 kV, while the acoustic properties were assessed with mode A ultrasound and a transducer frequency of 5 MHz. A breast phantom was created from TMP material with tissue equivalence and was then evaluated using mammography as well as ultrasound to analyze its image quality. The results showed that samples A (PVC 5%, DOP 95%), B (PVC 7%, DOP 93%), C (PVC 10%, DOP 90%), E (PVC 7%, DOP 90%, graphite 3%), and F (PVC 7%, DOP 90%, silicone oil 3%) have the closest equivalent to the ACR breast phantom material with a different range of 0.01-1.39 in the 23-35 kV range. Based on the evaluation of the acoustic properties of ultrasound, A had high similarity to fat tissue with a difference of 0.03 (dB cm- 1 MHz- 1) and 0.07 (106 kg m- 2 s- 1), while B was close to the glandular tissue with a difference of 9.2 m s- 1. Multilayer breast phantom images' results showed gray levels in mammography and ultrasound modalities. Therefore, this study succeeded in establishing TMP material for mammography and ultrasound. It can also be used for simple quality assurance and control programs.

Introduction: Short-term fasting may influence intraocular pressure (IOP) due to alteration of fluid (total body water;
TBW, and water intake) and fat (total body fat; TBF). This study aimed: i) to compare IOP values within and between,
fasting and non-fasting periods; and ii) to assess the association between IOP and, TBW and TBF. Methods: Thirty
healthy participants aged 21.8±1.1 years were assessed on two different periods (fasting vs. non-fasting). During each
period, the IOP, TBW and TBF values were assessed for four times (morning, afternoon, evening, late-evening). The
IOP was measured using AccuPen® tonopen, while TBW and TBF were assessed by using a Tanita body composition
analyser. Results: During fasting, the IOP value in the afternoon (14.53±2.33 mmHg) was significantly higher than in
the evening (12.43±2.73 mmHg, p=0.009) and late-evening (12.60±2.44 mmHg, p=0.003). No significant difference
in IOP was observed during non-fasting period. The mean of IOP in the evening was significantly lower during fasting
compared to non-fasting (12.43±2.73 mmHg vs 13.75±2.53 mmHg, p=0.044). The IOP and TBW were negatively
correlated (r=-0.268; p=0.011) during non-fasting and showed no association during fasting period. There was no
significant correlation between IOP and TBF during both fasting and non-fasting periods. Conclusion: IOP reduction
during short-term fasting, together with the no association with TBF and TBW suggested that IOP is an independent
factor that reduces during fasting in healthy population.

Fulltext COVID-19-related stress and anxiety are associated with negative body image in adults from the United Kingdom

Swami V, Horne G, Furnham A

Pers Individ Dif, 2021 Feb 15;170:110426.
PMID: 33046945 DOI: 10.1016/j.paid.2020.110426

The stress and anxiety caused by the coronavirus (COVID-19) pandemic presents a serious threat to psychological well-being in populations worldwide and may also extend to body image outcomes. To test this hypothesis, we conducted a preliminary study in which an online sample of adults from the United Kingdom (N = 506, age M = 34.25 years) were asked to complete measures of perceived stress, stressful life events, trait anxiety, COVID-19-related stress and anxiety, and negative body image (body dissatisfaction and drive for thinness in women, body fat and muscularity dissatisfaction in men). The results of hierarchical regressions indicated that COVID-19-related stress and anxiety explained significant incremental variance in body image outcomes (Adj. ΔR2 = .02 to .10), over-and-above demographics (age and body mass index) and perceived stress, trait anxiety, and stressful life events. These findings suggest that COVID-19-related stress and anxiety may shape body image outcomes under conditions of physical and social distancing.

Fulltext Muscle protein synthesis and muscle/metabolic responses to resistance exercise training in South Asian and White European men

Alkhayl FFA, Ismail AD, Celis-Morales C, Wilson J, Radjenovic A, Johnston L, et al.

Sci Rep, 2022 Feb 15;12(1):2469.
PMID: 35169204 DOI: 10.1038/s41598-022-06446-7

The aims of the current study, therefore, were to compare (1) free-living MPS and (2) muscle and metabolic adaptations to resistance exercise in South Asian and white European adults. Eighteen South Asian and 16 White European men were enrolled in the study. Free-living muscle protein synthesis was measured at baseline. Muscle strength, body composition, resting metabolic rate, VO2max and metabolic responses (insulin sensitivity) to a mixed meal were measured at baseline and following 12 weeks of resistance exercise training. Free-living muscle protein synthesis was not different between South Asians (1.48 ± 0.09%/day) and White Europeans (1.59 ± 0.15%/day) (p = 0.522). In response to resistance exercise training there were no differences, between South Asians and White Europeans, muscle mass, lower body strength or insulin sensitivity. However, there were differences between the ethnicities in response to resistance exercise training in body fat, resting carbohydrate and fat metabolism, blood pressure, VO2max and upper body strength with responses less favourable in South Asians. In this exploratory study there were no differences in muscle protein synthesis or anabolic and metabolic responses to resistance exercise, yet there were less favourable responses in several outcomes. These findings require further investigation.

Wu X, Zhang S, Lai J, Lu H, Sun Y, Guan W

Exp Clin Transplant, 2020 12;18(7):823-831.
PMID: 33349209 DOI: 10.6002/ect.2020.0108

OBJECTIVES: Liver fibrosis is inevitable in the healing process of liver injury. Liver fibrosis will develop into liver cirrhosis unless the damaging factors are removed. This study investigated the potential therapy of Bama pig adipose-derived mesenchymal stem cells in a carbon tetrachloride-induced liver fibrosis Institute of Cancer Research strain mice model.
MATERIALS AND METHODS: Adipose-derived mesenchymal stem cells were injected intravenously into the tails of mice of the Institute of Cancer Research strain that had been treated with carbon tetrachloride for 4 weeks. Survival rate, migration, and proliferation of adipose-derived mesenchymal stem cells in the liver were observed by histochemistry, fluorescent labeling, and serological detection.
RESULTS: At 1, 2, and 3 weeks after adipose-derived mesenchymal stem cell injection, liver fibrosis was significantly ameliorated. The injected adipose-derived mesenchymal stem cells had hepatic differentiation potential in vivo, and the survival rate of adipose-derived mesenchymal stem cells declined over time.
CONCLUSIONS: The findings in this study confirmed that adipose-derived mesenchymal stem cells derived from the Bama pig can be used in the treatment of liver fibrosis, and the grafted adipose-derived mesenchy-mal stem cells can migrate, survive, and differentiate into hepatic cells in vivo.

Fulltext Conjugating uncoupler compounds with hydrophobic hydrocarbon chains to achieve adipose tissue selective drug accumulation

Ng MY, Song ZJ, Venkatesan G, Rodriguez-Cuenca S, West JA, Yang S, et al.

Sci Rep, 2024 Feb 28;14(1):4932.
PMID: 38418847 DOI: 10.1038/s41598-024-54466-2

One potential approach for treating obesity is to increase energy expenditure in brown and white adipose tissue. Here we aimed to achieve this outcome by targeting mitochondrial uncoupler compounds selectively to adipose tissue, thus avoiding side effects from uncoupling in other tissues. Selective drug accumulation in adipose tissue has been observed with many lipophilic compounds and dyes. Hence, we explored the feasibility of conjugating uncoupler compounds with a lipophilic C8-hydrocarbon chain via an ether bond. We found that substituting the trifluoromethoxy group in the uncoupler FCCP with a C8-hydrocarbon chain resulted in potent uncoupling activity. Nonetheless, the compound did not elicit therapeutic effects in mice, likely as a consequence of metabolic instability resulting from rapid ether bond cleavage. A lipophilic analog of the uncoupler compound 2,6-dinitrophenol, in which a C8-hydrocarbon chain was conjugated via an ether bond in the para-position (2,6-dinitro-4-(octyloxy)phenol), exhibited increased uncoupling activity compared to the parent compound. However, in vivo pharmacokinetics studies suggested that 2,6-dinitro-4-(octyloxy)phenol was also metabolically unstable. In conclusion, conjugation of a hydrophobic hydrocarbon chain to uncoupler compounds resulted in sustained or improved uncoupling activity. However, an ether bond linkage led to metabolic instability, indicating the need to conjugate lipophilic groups via other chemical bonds.

Fulltext Acute cauda equina syndrome secondary to free fat graft following spinal decompression

Imran Y, Halim Y

Singapore Med J, 2005 Jan;46(1):25-7.
PMID: 15633005

A 63-year-old man developed acute cauda equina syndrome due to fat graft compression. Following decompressive laminectomy and posterior instrumented fusion with pedicle screw fixation for spinal stenosis of L5 and S1 vertebral levels, free fat grafting was performed to cover the exposed dura. The patient developed gradual neurological deficit three days postoperatively. This started with sensory loss and weakness of the affected dermatomes and myotomes, followed by bowel incontinence on the 12th postoperative day. Intraoperatively, significant dural compression by the fat graft was confirmed. Immediate removal of the fat graft resulted in recovery from cauda equina syndrome.

Malays J Nutr, 2018;24(2):203-213.
MyJurnal

Introduction: Conjugated linoleic acid (CLA) has been studied for its fat mass
reduction effects. This study aimed to determine the effects of CLA supplementation
on body fat mass (BFM) and selected blood lipid profiles among overweight Iranian.

Methods: A total of 180 adults with BMI = 26-29 kg/m2 and BFM exceeding 21%
and 28% for men and women, respectively were recruited through voluntary
participation from weight management clinics in Tehran. They were assigned
randomly to three groups as follows: Group (1) (control group) receives weight loss
diet only; Group (2) receives weight loss diet +3 gr/day CLA supplement (mixture
of cis-9, trans-11 and trans-10, cis-12) twice a day and Group (3) weight loss diet
+3 gr/day CLA supplement as Group (2) twice a day + regular exercise (walking at
5.5-6 km/h for at least 160 minutes/week). The trial was conducted for 12 weeks.
Anthropometric measurements and blood lipid profiles were determined at weeks 0,
6 and 12.

Results: Both Group 2 and Group 3 showed a significant between-group
difference in reduction of BFM (1.3% and 2.6% respectively) compared to Group 1.
Group 2 supplementation showed increased free fatty acid (FFA) (0.44 mM to 0.55
mM) and decreased HDL-chol (47.5 mg/dL to 42.0 mg/dL) between weeks 0 and
12. These results were not observed for Group 3.

Conclusion: Combination of CLA
supplementation with exercise showed BFM reduction in overweight Iranian adults.
Further research is suggested to verify the findings of this study.

Fulltext Leptin: a pleitropic factor in physiology

Fayez A Almabhouh, Faizatul Isyraqiah Ahmad Muhammad, Hisham Ibrahim, Harbindarjeet Singh

Journal of Clinical and Health Sciences, 2019;4(2):31-57.
MyJurnal

Leptin, a 16 kDa protein and a product of the ob/ob gene, has a tertiary structure similar to that
of a cytokine. It is primarily secreted by white adipose tissue and its levels in the blood correlate
positively with percentage body fat. Leptin was first identified in 1994 as a major factor that
regulated food intake and energy balance. Leptin in the circulation exists either as a free
monomeric hormone or bound to its soluble receptor. Its serum levels usually range from 0.5 to
37.7 ng/ml in males and 2.0 to 45.2 ng/ml in females. The half-life of leptin is between 20 - 30
minutes and it is eliminated mainly by the kidneys. However, research over the last 25 years
has revealed numerous other physiological roles for leptin, including roles in inflammation,
immune function, neuro-endocrine function, bone metabolism, blood pressure regulation and
sexual maturation. Most of these roles have been identified from studies on leptin deficient
rodents. Apart from energy balance and sexual maturation, where its role is direct and obvious,
its actions on the rest of the other systems are permissive. Actions of leptin are both centrally
and peripherally mediated involving receptors that are widely distributed in the body. Six leptin
receptor isoforms, belonging to the class 1 cytokine receptor family, have been identified.
These receptors are products of the OBR gene. The cellular actions of leptin are mediated
through any one of five different signalling pathways that include the JAK-STAT, PI3K, MAPK,
AMPK, and the mTOR signalling pathways.
