Effects of exercise on obesity

Diet and exercise. Eat less, move more... Burn more than you consume. This is a constant drumbeat in this fat world.

But what type of exercise--strength training, endurance training, maybe a combination?

A team of researchers in Spain, working as part of the Nutrition and Physical Activity Program for Obesity Treatment, suggests that the type of exercise may not be as important as previously thought.

Their findings can be found in the J of Applied Physiology.

They followed 96 people (48 men, 48 women) from 18 through 50 in a 22-week supervised program. They all followed a similar reduced-calorie diet.

Then the subjects were randomly assigned to three exercise regimens...Endurance (their choice of running, elliptical, cycling), strength (shoulder press, squats, barbell row, biceps curl, lateral split, front split, bench press, and French press), or a combination.

They exercised three times a week for the same length of time and at the same intensity.

They also were advised to get 30-60 minutes of exercise on most, if not all, days of the week for a total of 200-300 mins of moderate-intensity activity. Walk, instead of drive, stairs not elevator, etc.

Upshot? All lost significant weight and increased lean mass.  The type of exercise apparently made no difference.

Then they made a sort of cryptic statement: "A calorie burned in exercise is not the same as one not ingested."

Have to think about that one.
