Diet and Exercise Work Better Than Diet Alone
In dieting, the journey may matter more than the destination. Shedding calories through a combination of diet and exercise proved healthier than consuming fewer calories alone, a study found. One group dieted to reduce caloric intake by 25 percent, while another consumed 12.5 percent fewer calories and burned an equal amount during workouts. Both groups lost similar amounts of weight over the six-month study, but the exercisers showed greater improvements in aerobic fitness, LDL ("bad") cholesterol levels, diastolic blood pressure, and insulin sensitivity.
