Abstract
BACKGROUND:
Obesity and overweight are increasing in prevalence in developed countries as a result of changing dietary habits and a lack of physical activity. The purpose of the present study was to evaluate the changes in body composition during short-term overfeeding using the three-component model, which is composed of fat mass (FM), total body water (TBW), and fat-free dry solids (FFDS).
METHODS:
Ten healthy men completed 3 days of overfeeding during which they consumed 1,500 kcal/day more energy than consumed in their normal diets. Body composition was evaluated at three time points: the day before and after their normal diets and the day after the 3-day overfeeding diet.
RESULTS:
Before and after their normal diets, there were no significant differences in body weight and composition, but after 3 days of overfeeding, body weight, TBW, and FFDS increased 0.7, 0.7, and 0.2 kg, respectively (P <0.0001). There was no significant difference in FM between the normal and overfeeding diets.
CONCLUSION:
This study suggests that TBW gain contributes to weight gain following a short-term overfeeding.

(לא עברתי עדיין על המחקר)
מחקר חדש שיצא טוען שאכילה מופרזת של 1500 קל׳ מעל מה שרגילים לצרוך במשך 3 ימים, לא תוביל להשמנה.
לאחר 3 ימים נצפתה העלאה בשומן (Fat Mass), נוזלים ו FFDS (איך שלא קוראים לזה בעברית).
בעיות פוטנציליות:
1. שיטות מדידה
2. מחקר קצר מידי
3. רק 10 משתתפים
אבל.. עדיין מעניין
