Health Shorts: exercise crucial to healthy weight loss

It’s possible to lose weight by diet alone, but you’ll gain more health benefits if you include exercise as part of the plan. In a randomized clinical study, overweight men and women all lost weight during a six-month program requiring a 25 percent energy deficit. One group eliminated 25 percent of their daily calories through diet alone; the other eliminated 12.5 percent through diet and 12.5 percent through regular aerobic exercise.

While both groups saw reductions in body mass, fat mass and abdominal obesity, the diet plus exercise group had greater improvement in insulin sensitivity, LDL cholesterol and diastolic blood pressure.
