Résumé
OBJECTIVE: The therapeutic effectiveness of diet, exercise, and diet plus exercise for weight loss in obesity was determined. DATA SOURCES: All human research reported in English, published in peer-reviewed scientific journals within the past 25 y was reviewed. STUDY SELECTION: Acceptance criteria (n = 493 from > 700 studies) were that a therapeutic intervention of diet, exercise or diet plus exercise was employed, specifically for weight reduction in obese adult humans and that weight change was reported numerically. Only aerobic exercise studies were included, while drug, hormone and surgical treatments were excluded. DATA EXTRACTION: All data were extracted by the same investigator from the original research report. Except for gender and program type, all extracted data were numerical. DATA SYNTHESIS: ANOVA, with a Newman-Keuls post hoc test, was used to determine differences among programs (P < 0.05). One analysis was performed on the group mean data and one based on effect sizes. Analyses were repeated using initial body weight, initial percent body fat and program length, as covariates. RESULTS: Primarily, subjects aged 40 y have been studied (39.5 ± 0.4 y, mean ±s.e.m.) who are only moderately obese (92.7 ± 0.9 kg, 33.2 ± 0.5 body mass index (BMI). 33.4 ± 0.7% body fat); for short durations (15.6 ± 0.6 weeks). Exercise studies were of a shorter duration, used younger subjects who weighed less, had lower BMI and percentage body fat values, than diet or diet plus e
