The Current Obesity Epidemic: Unravelling the Evolutionary Legacy of Adipose Tissue

Abstract: The evolution of organisms is shaped by the selective pressures to which they are subject. Selective pressures produce a trade-off between costs and benefits that ultimately influences the fitness of the whole organism. Classically, it has been pointed out that food intake is allocated between its use for physiological functions and its store for future utilization. Moreover, it is accepted that the perfect survivor must be able to eat and store as many calories as possible when food is available as a buffer a… Show more

“…As in other animals, humans have a propensity to over-eat when food is readily available and the ability to store excess energy as fat. These excess fat stores can then be drawn upon during future food shortages (Kardum et al 2008;Korte et al 2005;Zafon and Simo 2011;Saad 2011). Natural selection would also likely favor preferences among different food items, with positive selection for preferences which maximize caloric intake rate-this logic is the foundation of optimal foraging theory (Dusseldorp 2012;Lieberman 2006;Pinel et al 2000;Pyke et al 1977).…”

“…Возможность запасания энергии в форме гликогена в печени и мышцах достаточно ограничена и составляет 1 ккал/г, в то время как энергетическая ценность жира, сосредоточенного в адипоцитах в форме триглицеридов, соответствует 8 ккал/г. Кроме того, гидрофобные особенности триглицеридов позволяют сохранять энергию без негативных осмотических последствий [60].…”

“…Депонируемый жир обеспечивает энергозапасы в 88 500 ккал у мужчин и 132 500 ккал -у женщин. Таким образом, при суточных энергозатратах в 1350 ккал энергетические потребности организма могут удовлетворяться в течение 60-90 дней [45,60].…”
