The consumption of specific foods in energy-restricted

diets may affect the weight loss process. The purpose

of this research was to evaluate whether obese women

following two hypocaloric diets with distinct fruit

content differ in weight loss and metabolic responses.

Fifteen obese women were included, who were randomly

assigned to follow a low or a high-fruit

energy-restricted diet for 8 weeks. The main outcome

variables were weight and fat losses. Metabolic

measurements concerning macronutrient oxidation were

also assessed by using (13)C labelled fructose and

indirect calorimetry. The induced weight loss was

similar for both diets (6.9 +/- 2% vs. 6.6 +/- 2%, p =

0.785). Both experimental diets similarly improved the

lipid plasma profile in the participants, but the

cholesterol fall was higher in obese subjects

receiving the diet containing more fruit. No

statistical differences in lipids carbohydrates and

(13)C labelled fructose utilisation were observed, but

protein oxidation was differently affected by the

experimental diets. The compensatory effects of the

associated fibre/fructose intake may explain the lack

of a specific effect of the fruit amount on

hypocaloric diets designed to weight loss, although

the increased fibre content from enriched fruit diets

may be involved in the favourable effects on

cholesterol plasma levels.
