Relationship between diet-induced changes in body fat and appetite sensations in women.

To quantify the impact of weight/fat loss on appetite sensations, 54 overweight women followed a caloric restriction program (-2900 kJ/day). Their body composition and appetite sensations were assessed. Visual analogue scales (VAS) were used to measure desire to eat, hunger, fullness and prospective food consumption. The results showed that there is a significant association between the decrease in body fat mass and the change in appetite sensations, predicting a 5.8-mm increase in desire to eat and a 3.6-mm decrease in fullness per kg fat loss. This quantified relationship could serve as a reference point to evaluate the satiating efficiency of functional foods when they are combined with a weight-reducing program.
