Abstract This study examines the secondary effects of hypocaloric diets. The results show that the positive short-term effects with regards health are not maintained in the long term, as most people eventually return to their original weight. A description is given of how psychological reasons are more important than biological mechanisms when explaining this failure and stress is put on how carrying out successive hypocaloric diets can result in a subgroup of people becoming overweight or… 
The World Health Organization worked out practical recommendations regarding obesity prevention that require sustained political commitment and the collaboration of public stakeholders, private sector and the whole population.
The objective of this paper is to present the physiological and psychological barriers to weight loss and its long-term maintenance, and to describe the role of the clinical psychologist in the treatment of overWEIGHT and OBESITY.
Diet Versus Exercise in Weight Loss and Maintenance: Focus on Tryptophan
The disturbed metabolism of TRP might affect biosynthesis of serotonin and could thereby increase the susceptibility for mood disturbances and carbohydrate craving, increasing the cessation probability of weight reduction programs.
Treatment of Obesity With “Combination” Pharmacotherapy

A novel combination pharmacotherapy developed in clinical practice is described, the combination of phentermine with the serotonin precursor l-5-hydroxytryptophan plus the peripheral decarboxylase inhibitor, carbidopa, which can make important contributions to the treatment of obesity.
Weight Loss and the Prevention of Weight Regain: Evaluation of a Treatment Model of Exercise Self-Regulation Generalizing to Controlled Eating.
Evaluating a new, theory-based protocol in which exercise support methods are employed to facilitate improvements in psychosocial predictors of controlled eating and sustained weight loss suggested change in self-regulation best predicted weight loss, whereas change in Selfefficacy best predicted maintenance of lost weight.
Factors influencing women’s choice of weight-loss diet
A typology of eight minimally overlapping weight-loss diet methods was developed and used to survey 151 women dieters, revealing a potentially problematic "thin, quick, and easy" association of methods and motives, as well as a more healthful “thin, natural, life-style” association.
Effects of a caloric restriction weight loss diet on tryptophan metabolism and inflammatory biomarkers in overweight adults
Since disturbed metabolism of Trp affects biosynthesis of serotonin and might be associated with increased susceptibility for mood disturbances and carbohydrate craving, strategies to supplement Trp while dieting could be highly useful in treating uncontrolled weight gain or in preventing neuropsychiatric symptoms.
Caloric Restriction Experience Reprograms Stress and Orexigenic Pathways and Promotes Binge Eating
Reprogramming of key central pathways involved in regulating stress responsivity and orexigenic drives by moderate caloric restriction experience is revealed, suggesting that management of stress during dieting may be beneficial in long-term maintenance.
The effect of a low-fat, high-protein or high-carbohydrate ad libitum diet on weight loss maintenance and metabolic risk factors
Results show that low-fat, high-casein or whey protein weight maintenance diets are more effective for weight control than low- fat, HC diets and do not adversely affect metabolic and cardiovascular risk factors in weight-reduced moderately obese subjects without metabolic or cardiovascular complications.
Macronutrients and obesity: views, news and reviews
Research aimed at elucidating molecular mechanisms governing the effects of macronutrients on the differentiation and function of white fat cells is reviewed, as nutrient homeostasis is to a large extent orchestrated by the gut–brain axis.


A dietary approach to bulimia treatment
Long-term effects of a very low calorie diet (Nutrilett®) in obesity treatment. A prospective, randomized, comparison between VLCD and a hypocaloric diet+behavior modification and their combination
OBJECTIVES. To compare weight loss on a balanced hypocaloric diet to that of a Very Low Calorie Diet (VLCD) after two months of treatment and to further compare 26 months of weight maintenance and
Should we recommend low‐fat diets for obesity?
In overweight or obese individuals who are dieting for the purpose of weight reduction, low‐fat diets are as efficacious as other weight‐reducing diets for achieving sustained weight loss, but not more so.
Effects of weight cycling on the resting energy expenditure and body composition of obese women.
The results do not support claims that weight cycling adversely affects REE, body composition, or body fat distribution.
Food groups as predictors for short-term weight changes in men and women of the EPIC-Potsdam cohort.
The data show that a diet rich in high fat and high energy foods predicts short-term weight gain even if controlled for many potential confounding factors.
Risk factors for hypertension in obese women. The role of weight cycling
Findings could support the hypothesis that it is the combined exposure of central-type obesity and WC that strongly raises the risk of hypertension among obese women.
The dieting maelstrom. Is it possible and advisable to lose weight?
The primary challenges are to identify individuals who will be helped or harmed by dieting, to reduce the frequency and severity of dieting in those for whom the costs exceed the benefits, and to better understand the physiological and psychological reasons why some people can lose and others cannot.
Effects of weight cycling caused by intermittent dieting on metabolic rate and body composition in obese women.
No evidence in this group of obese women that weight cycling leads to a progressive decrease in BMR or increase in the proportion of body fat is found.

VLCD combined with behaviour modification is a useful mode of therapy for obesity with low drop-out rate and majority of patients below pretreatment weight at the two-year control.
Variability of body weight and health outcomes in the Framingham population.
It is found that the positive associations between fluctuations in body weight and end points related to mortality and coronary heart disease could not be attributed to these potential confounding factors, independent of obesity and the trend of body weight over time.
