What more effective for weight loss diet or exercise

To learn more about why, I read through more than 60 studies including high-quality, systematic reviews of all the best-available research on exercise and weight loss for a recent installment of Show Me the Evidence. One very underappreciated fact about exercise is that even when you work out, the extra calories you burn only account for a small part of your total energy expenditure. There are three main components to energy expenditure, obesity researcher Alexxai Kravitz explained: 1 basal metabolic rate, or the energy used for basic functioning when the body is at rest; 2 the energy used to break down food; and 3 the energy used in physical activity.

Digesting food accounts for about 10 percent. That leaves only 10 to 30 percent for physical activity, of which exercise is only a subset.

Remember, physical activity includes all movement, including walking around, fidgeting, et cetera. The implication here is that while your food intake accounts for percent of the energy that goes into your body, exercise only burns off less than 10 to 30 percent of it. Using the National Institutes of Health's Body Weight Planner — which gives a more realistic estimation for weight loss than the old 3, calorie rule — mathematician and obesity researcher Kevin Hall created this model to show why adding a regular exercise program is unlikely to lead to significant weight loss.

If a hypothetical pound man added 60 minutes of medium-intensity running four days per week while keeping his calorie intake the same, and he did this for 30 days, he'd lose five pounds. More on these "compensatory mechanisms" later. So if one is overweight or obese, and presumably trying to lose dozens of pounds, it would take an incredible amount of time, will, and effort to make a real impact through exercise alone.

How much we eat is connected to how much we move.

Is Diet Really More Effective Than Exercise for Weight Loss?

One study shows that people seemed to increase their food intake after exercise — either because they thought they burned off a lot of calories or because they were hungrier. Another review of studies from found that people generally overestimated how much energy exercise burned and ate more when they worked out. Doing so will guarantee that key deficit. But the quality of the food actually matters more than the quantity. Basically, whole, unprocessed foods will not only make you feel really good but help you lose weight, too.

A positive relationship with food with also prevents you from spiraling into a crash diet. Plus, we know the benefits of working out extend far beyond weight loss.
