"A program of diet plus lifestyle activity may offer similar health benefits and be a suitable alternative to diet plus structured aerobic activity for obese women," concludes a recent study the Johns Hopkins University School of Medicine in Baltimore, Maryland.
Obese women who engaged in a four-month program of structured aerobic exercise in addition to a 1200 calorie low-fat diet lost 18.3 pounds compared to 17.4 pounds for those who followed a program of moderate-intensity lifestyle activity plus diet.
Those in the aerobic-plus-diet group lost less lean body mass than the lifestyle-plus diet group (1.1 pounds versus 3.1 pounds, respectively).
However, during a one-year follow-up the aerobic-plus-diet group gained back a few pounds more than the lifestyle-plus-diet group (+3.5 pounds versus +0.2 pounds, respectively).
Total cholesterol and triglyceride levels were 10 and 16 percent lower, respectively, after four months, but were not significantly lower at the end of the one year follow-up.
The study included forty obese women with an average body mass index of 33, body weight of 196 pounds and age of 43-years.
The authors noted that only 22 percent of Americans exercise regularly.
