Weight loss diet beneficially affects blood adiponectin concentrations .
Adiponectin secreted from adipose tissue is proposed to be inversely related to the body fat mass .
However , the magnitude of the effect of low calorie diet on adiponectin concentrations remains unknown .
The present study was aim ed to conduct a systematic review and meta- analysis on clinical trials that access the effect of low calorie diet on adiponectin concentration .
Hormonal and psychobehavioral predictors of weight loss in response to a short-term weight reduction program in obese women.
Among the factors influencing weight loss and maintenance , psychobehavioral , nutritional , metabolic , hormonal and hereditary predictors play an important role . Psychobehavioral factors influence adherence to lifestyle changes and thus weight loss maintenance . The outcome of short-term weight reduction treatment is mainly affected by changes in energy and nutrient intake and physical activity and thus the impact of hormones can possibly be obscured . In order to reveal hormonal determinants of weight loss , a 4-week in-patient comprehensive weight reduction program was introduced in which food intake and physical activity were under the strict control . Women ( n = 67 , BMI : 32.4+/-4.4 kg ; age : 48.7+/-12.2 years ) who exhibited stable weight on a 7 MJ/day diet during the first week of weight management were given a hypocaloric diet yielding daily energy deficit 2.5 MJ over the subsequent 3-week period . This treatment result ed in a mean weight loss of 3.80+/-1.64 kg . Correlation analysis revealed that baseline concentrations of several hormones were significantly associated either with a higher ( free triiodothyronine , C-peptide , growth hormone , pancreatic polypeptide ) or with a lower ( insulin-like growth factor-I , cortisol , adiponectin , neuropeptide Y ) reduction of anthropometric parameters in response to weight management . In a backward stepwise regression model age , initial BMI together with baseline levels of growth hormone , peptide YY , neuropetide Y and C-reactive protein predicted 49.8 % of the variability in weight loss . Psychobehavioral factors ( items of the Eating Inventory , Beck Depression score ) did not contribute to weight change induced by a well-controlled short-term weight reduction program
