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...

Comment les régimes amaigrissants font grossir : d’une perspective d’autorégulation de la composition corporelle = How dieting makes some fatter: From a perspective of human body composition autoregulation

Dulloo, Abdul G. ; Jacquet, Jean ; Seydoux, Josiane ; Montani, Jean-Pierre

In: Cahiers de Nutrition et de Diététique, 2013, vol. 48, no. 1, p. 15–25

Le titre d’un livre publié en 1983 ‘Dieting Makes You Fat’ – concrétise la notion que faire un régime pour contrôler son poids, et par conséquent l’effet yo-yo, prédispose l’individu à être encore plus gras. Alors que cette notion est controversée, son débat souligne le fossé qui existe dans notre compréhension des lois fondamentales de la physiologie qui gouvernent la...

The thrifty 'catch-up fat' phenotype: its impact on insulin sensitivity during growth trajectories to obesity and metabolic syndrome

Dulloo, Abdul G. ; Jacquet, Jean ; Seydoux, Josiane ; Montani, Jean-Pierre

In: International Journal of Obesity, 2006, vol. 30, no. S4, p. S23–S35

The analyses of large epidemiological databases have suggested that infants and children who show catch-up growth, or adiposity rebound at a younger age, are predisposed to the development of obesity, type 2 diabetes and cardiovascular diseases later in life. The pathophysiological mechanisms by which these growth trajectories confer increased risks for these diseases are obscure, but there is...

Adaptive thermogenesis and uncoupling proteins: a reappraisal of their roles in fat metabolism and energy balance

Dulloo, Abdul G. ; Seydoux, Josiane ; Jacquet, Jean

In: Physiology & Behavior, 2004, vol. 83(4), p. 587-602

After decades of controversies about the quantitative importance of autoregulatory adjustments in energy expenditure in weight regulation, there is now increasing recognition that even subtle variations in thermogenesis could, in dynamic systems and over the long term, be important in determining weight maintenance in some and obesity in others. The main challenge nowadays is to provide a...
