Thirteen females were randomly assigned to either a low-fat diet (20-25% of calories as fat) or a control diet (35-40% fat) for 11 wk. After a 7-wk washout period, the conditions were reversed for another 11 wk. Energy intake on the low-fat diet gradually increased by 0.092 kJ/wk resulting in a total caloric compensation of 35% by the end of the 11-wk treatment period. This failure to compensate calorically on the low-fat diet resulted in a deficit of 1.22 kJ/d and a weight loss of 2.5 kg in 11 wk, twice the amount of weight lost on the control diet. These results demonstrate that body weight can be lost merely by reducing the fat content of the diet without the need to voluntarily restrict food intake.

Variation in energy intake during the menstrual cycle: implications for food-intake research

Journal article (peer-reviewed)abstract
- Division of Nutritional Sciences, Cornell University, Ithaca, NY. The relationship between spontaneous energy consumption and menstrual cycle was evaluated in 23 subjects who participated in one of two independent studies. Ad libitum intakes of experimental diets were measured by food weighing and bomb calorimetry for 56 or 42 d. Comparisons were made between each woman's mean energy during the 10 d before and after the onset of menstruation. The significant decline (364 kJ, or 87 kcal) between these two 10-d intervals was smaller than but consistent with findings from previous studies of data from food journals. In a separate analysis with time-series techniques, two distinct periods of elevated intake were identified (during the midluteal and midfollicular phases) that were independent of illness and menstrual symptoms. This pattern of food intake is discussed with reference to normal hormonal fluctuations. These findings confirm that menstrual cycle is a potential confounding variable that should be controlled in research on human food intake. PMID: 3421205 [PubMed - indexed for MEDLINE]
