Strange, new diets, treatments and exercise programs arrive on the market every day. Each one promises to help people lose weight and get a beach beautiful body. The weight loss industry takes in billions of dollars each year, and it is growing.
BOB DOUGHTY: One research company says the weight loss business will be worth more than five hundred eighty billion dollars worldwide by the year twenty fourteen. MarketsandMarkets also says the food and drink market represents the largest part of that growth. It is expected to reach more than three hundred fifty five billion dollars by twenty fourteen.
There is a seemingly endless supply of ideas about how to lose weight. There are low-carbohydrate diets and low-fat diets, diets that limit calories and ones that let you eat as much as you want. And, there are thousands of different kinds of diet pills and programs. So where does one begin? Which one is best?
SHIRLEY GRIFFITH: Experts say there is no single diet plan that works best for everyone. Many experts agree on one thing: that to lose weight, you must use or burn off more calories than you take in. When you eat more calories than your body needs, it stores that extra energy as fat.
Calories are a measure of energy in food. A pound of fat is equal to about four hundred fifty three grams or three thousand five hundred calories. To lose that fat in a week, you have to burn off at least that amount in calories or eat that much less. The best thing to do is to combine both ideas. Eat fewer calories and increase physical activity so that you burn off more.
