There are several truths to losing weight and body fat. These truths are static despite diets, pills and gimmicks.
You have to decrease how many calories you eat, you have to change what you eat and you have to exercise.
Sure you can go for a quick fix by committing to a diet that you won't stick to or temporarily change your lifestyle to lose ten pounds. But the weight will come back and possibly return with more weight than when you began.
You have to change your life. Food can't be a diet. It has to be the way you eat and consist of foods you consume no matter where you are and regardless of the time of year. And exercising can't be viewed as a chore. It has to be a part of your natural life like eating and sleeping -- two things that are essential for human life.
Burning calories is two-fold. To be successful, you need to eat a small amount of calories (that amount is determined by your personal goals) and you need to exercise or participate in a physical activity that will burn calories.
When you burn calories, you burn fat and you eventually lose weight. That's it. That's the formula for getting rid of the weight and keeping it off.
Here are two articles to read. One provides specific ways to maximize your calorie burn. The second article provides a list of foods that promote calorie burning during digestion (negative calorie foods) and foods that boost metabolism.
Please note that eating the negative calorie foods should not take the place of exercise although it is sometimes promoted.
