Losing weight and keeping it off is something achievable. You have to view it as a change of lifestyle, not a diet. Actually, in order to lose weight, you need to burn more calories than you eat. That is all. Also, I suggest you to do some weight training while dieting because you will maintain and strenghten your muscles.

If you wonder how to lose weight fast, I regret to tell you that there is no miracle solution. Weight loss diets that focuse on only one type of food are not good at all because your body will lack nutrients. Also, stay away from diets that recommend you to eat below 1,200 calories per day because this is the minimal amount of calories that your body needs to function.

Also, you need to consult a height and weight chart to know if you have to lose weight or not. Many are available on the Internet and, that way, you will see a range of weight that you have to be in to be healthy.

On the other hand, if you want to know how to gain weight, it is also very simple. To gain 1 pound per week, you have to eat 500 extra calories per day. Also, try to eat food that have more calories like cheese to reach your goal.
