Everybody knows about lots of relatively easy things on weight loss. 1. However, if you have ever tried some before without success, then the following guides could be more useful for your life.

There’s no magical diet.

We often think that if we can just discover the “right” kinds of foods, we’ll magically lose weight or maintain what we’ve lost. In fact there doesn’t seem to be any “right” diet, and there doesn’t seem to be any evidence that one particular diet will work better with an individual’s body.   __2.

Dieting gets the better of exercising.

It is said that exercise is the key to weight loss—taking the stairs instead of the elevator will make a difference, for instance. 3.  Decreasing food intake is much more effective than increasing physical activity to achieve weight loss. Of course, both together would be even better.

Work harder than other people.

Exercise may not help go back to what it was before you gained weight. So if you’ve been overweight and you lose weight, maintaining that loss means you’re probably going to have to work harder than other people. Building muscles can help your body burn a few more calories.   4.  It seems unfair, but that’s the way it is.

5.   

For energy balance, it’s the number of calories that counts. It’s certainly true at least in theory and sometimes in practice. You can gain weight eating too much healthy food as well as unhealthy food. So the point is not to question what a calorie is, but rather to understand that we need to exchange the calorie-packed foods for foods that are less calorie-dense and more nutritionally dense.

A. All calories are created equal.

B. Some of them are also extremely effective when actually carried out.

C. A calorie is a calorie!

D. We know pretty much that any diet will work if you follow it.

E. However, it’s much more efficient to cut calories.

F. Some of the calories we burn come from our basic exercise.

G. However, it’s also likely that you’ll have to do more in the long run.
