Dieting Will Help You <br />Lose Weight More Than Exercise According to the National Institute of Diabetes <br />and Digestive and Kidney Diseases, up to 15% of an average person's daily calories <br />are burnt through exercise. This isn't even close to food consumption, <br />which takes up to 100% of a body's energy. Nutritionist Lisa Drayer, via 'CNN' A study from Harvard Medical School adds that the benefits of exercise are very easily undone <br />by eating the wrong foods. Eating a few chocolate chip cookies can cancel out 200 calories burned from walking 30 minutes at a brisk pace. So if you want to lose some weight, <br />its more effective to improve your diet.
