Pathways from dieting to weight regain, to obesity and to the metabolic syndrome: an overview

Dulloo, Abdul G. ; Montani, Jean-Pierre

In: Obesity Reviews, 2015, vol. 16, p. 1–6

Every year, scores of millions of people – as diverse as obese and lean, teenagers and older adults, sedentary and elite athletes, commoners and celebrities – attempt to lose weight on some form of diet. They are often encouraged by their parents, friends, health professionals, training coaches, a media that promotes a slim image and a diet- industry that in Europe and United States alone...

How dieting makes the lean fatter: from a perspective of body composition autoregulation through adipostats and proteinstats awaiting discovery

Dulloo, Abdul G. ; Jacquet, Jean ; Montani, Jean-Pierre ; Schutz, Yves

In: Obesity Reviews, 2015, vol. 16, p. 25–35

Whether dieting makes people fatter has been a subject of considerable controversy over the past 30 years. More recent analysis of several prospective studies suggest, however, that it is dieting to lose weight in people who are in the healthy normal range of body weight, rather than in those who are overweight or obese, that most strongly and consistently predict future weight gain. This paper...

Dieting and weight cycling as risk factors for cardiometabolic diseases: who is really at risk?

Montani, Jean-Pierre ; Schutz, Yves ; Dulloo, Abdul G.

In: Obesity Reviews, 2015, vol. 16, p. 7–18

Despite the poor prognosis of dieting in obesity management, which often results in repeated attempts at weight loss and hence weight cycling, the prevalence of dieting has increased continuously in the past decades in parallel to the steadily increasing prevalence of obesity. However, dieting and weight cycling are not limited to those who are obese or overweight as substantial proportions of...

Thrifty metabolism that favors fat storage after caloric restriction: a role for skeletal muscle phosphatidylinositol-3-kinase activity and AMP-activated protein kinase

Summermatter, Serge ; Mainieri, Davide ; Russell, A. P. ; Seydoux, Josiane ; Montani, Jean-Pierre ; Buchala, Anthony J. ; Solinas, Giovanni ; Dulloo, Abdul G.

In: Faseb Journal, 2008, vol. 22, p. 774-785

Energy conservation directed at accelerating body fat recovery (or catch-up fat) contributes to obesity relapse after slimming and to excess fat gain during catch-up growth after malnutrition. To investigate the mechanisms underlying such thrifty metabolism for catch-up fat, we tested whether during refeeding after caloric restriction rats exhibiting catch-up fat driven by suppressed...
