The loss of weight was analysed in a group of sixty overweight/obese women of childbearing age (20-35 years) according to their initial vitamin D status. Subjects were randomly assigned to one of two slightly hypocaloric diets: Diet V, in which the consumption of vegetables was increased, or Diet C, in which the relative consumption of cereals (especially breakfast cereals) was increased. Diete...

OBJECTIVE To study the effects of high-protein versus high-carbohydrate diets on various metabolic end points (glucoregulation, oxidative stress [dichlorofluorescein], lipid peroxidation [malondialdehyde], proinflammatory cytokines [tumor necrosis factor-α and interleukin-6], adipokines, and resting energy expenditure [REE]) with high protein-low carbohydrate (HP) and high carbohydrate-low prot...

Approximately 80% of patients with type 2 diabetes are overweight/ obese (1), and weight loss is the mainstay of treatment for these individuals. However, there is growing controversy as to whether reduced-fat or reduced-carbohydrate diets are best suited for this purpose, and results (2–8) in nondiabetic subjects suggest that lower carbohydrate diets are similarly or more efficacious in improv...

BACKGROUND AND OBJECTIVE The aim of our study was to investigate the influence of G-308 promoter variant of the tumor necrosis factor (TNF) alpha gene on metabolic changes and weight loss secondary to a high monounsaturated fat vs a high polyunsaturated fat hypocaloric diet in obese subjects. PATIENTS AND METHOD A sample of 261 obese subjects were enrolled in a consecutive prospective way, fr...

OBJECTIVE The recommended composition of a hypocaloric diet for obese women with polycystic ovary syndrome (PCOS) is unclear. The aim of this study was to investigate the effects of a high-protein, low-glycemic-load diet compared with a conventional hypocaloric diet on reproductive hormones, inflammatory markers, lipids, glucose, and insulin levels in obese women with PCOS. METHODS A total of...

There is considerable uncertainty over whether any one dietary pattern broadly facilitates weight loss or maintenance of weight loss, and current dietary guidelines recommend a spectrum of dietary composition for the general population. However, emerging evidence suggests that specific dietary compositions may work better for identifiable groups of overweight/obese individuals based on their in...

Background Intermittent fasting (IF) is a dietary strategy that has recently gained popularity due to a number of potential health benefits. One form of IF, termed time-restricted feeding (TRF), only allows caloric intake during a limited window of time each day (often 4 to 8 hours in duration). One concern of IF is the potential loss of lean mass due to the fasting periods. Resistance training...

conclusions aed improved liver enzymes in obese women. however, mild, transient increases in alt and ast values can be observed immediately after an nfd in women. results of 108 participants, 50 women in aed group and 50 women in nfd group completed the protocol of the study (response rate: 92.6 %). the aed led to a median weight loss of 3.79 kg (interquartile range: 4.4 kg). significant decrea...

The beneficial effects of high-fat, low-carbohydrate (HFLC) diets on glucose metabolismhave been questioned and its liver metabolism are not totally clear. This workaimed to evaluate the HFLC diet under different energy conditions glucosehomeostasis, fatty development hepatic gluconeogenesis using isolated perfusedrat liver. (79% fat, 19% protein, 2% carbohydrates in Kcal%) wasadministered rats...

BACKGROUND & AIMS Low glycemic index (GI) based diets could influence the accompanying physiological adaptations to energy restriction in the treatment of obesity. It was aimed to investigate the effects of two energy-restricted diets with different food distribution and GI values on weight loss and energy metabolism in the nutritional treatment of obesity. SUBJECTS AND METHODS Participants (...
