Abstract
The aim of this investigation was to study the effectiveness of both diet and exercise toward weight loss over an eight-week period, followed by a 7-8 month "follow-up" period to determine the maintenance of weight lost in individuals who had initially been 20 to 50 percent overweight.
In order to achieve these objectives, an experimental design involving one hundred and sixty (160) male volunteers, 29-69 years of age, divided into the four dietary groups (1,000 calories protein modified fast = PSMF; 1,000 calories balanced caloric deficit diet = BCDD; 420 calories liquid protein formula = DPC-70; and 800 calories balanced liquid formula = DPC-800) was carried out, with or without a supervised exercise program. Therefore, a total of eight experimental groups were studied.
All subjects participated in weekly meetings for nutritional, exercise, and behavior modification counselling. The exercised subjects also participated in a separate supervised program, three times per week, consisting of aerobic, strength, flexibility, and "relaxation" training, for a total of 24 sessions.
It was found that the exercised BCDD diet group lost signifycantly more weight than the non-exercised BCDD diet; no significant differences were noted among the other diet groups. An overall evaluation of all four diets demonstrated that the inclusion of the exercise program resulted in significant changes in percent of ideal weight loss, resting heart rate, maximum oxygen uptake (V0 subscript 2 Max), "treadmill ride-time", "cybex endurance", quadriceps, and hamstrings strength tests. In addition, the combined exercised groups showed improvements that were not statistically significant in actual body weight loss, percent body fat, diastolic and systolic blood pressures as well as blood cholesterol, high density lipoproteins, triglycerides, and lactic acid levels.
Seven to eight months after the end of the eight-week treatments, the previously exercised groups showed significantly less weight regain for the PSMF, DPC-800, and DPC-70 diet groups.
The results of this investigation indicate that exercise clearly is a desirable and perhaps a necessary part of any comprehensive weight reduction program. It has a favorable effect on the rate of weight loss, helps spare and increase muscle mass, apparently improves vital biochemical parameters, and assists in the maintenance of a more desirable body weight.
