Jose is right. The only way to lose fat and keep it off is through proper diet and exercise. For the diet, talk with a nutritionist or dietician. They will put you on a healthy diet. It's a waste of time and effort (as well as dangerous) to figure out one yourself and chances are you'll be wrong anyway. Also, for exercise, the best one for losing fat is walking (30 minutes a day, at least 5 days a week). By keeping your heartrate below 55-65% of your max. calculated heartrate will allow you to burn more fat than carbs. Stay away from those phoney diets. They will only do you harm and cost you money. The biggest problem with people trying to lose weight on their own is that they think they are experts. What a waste (waist)! Also, some people think lifting weights is the way to go. But, lose the fat, then lift the weights otherwise, you'll have muscles building up under the fat and you'll never see them. I also read an article that said that people who are overweight after age 30, lose one year off their lifespan for every year over 30 years of age that they are overweight. Food for thought! One thing to remember about Carbs, is that the body needs those carbs. The brain is the major user of carbs. Carbs are a readily available supply of glucose while fat cells and protein have to be broken down first. Also, watch your protein input. Protein has to be broken down by the kidneys, and the higher level of protein can overwork the kidneys to failure. Something to consider when looking into these "fly by night" diets. The moral to all of this is: take the time to consult experts before you diet and stay away from fad diets.
