The world has now formally recognized that the problem of overweight and obesity is a leading health problem. While there are no precise estimates, over a billion people around the world are facing problems from overweight and obesity. In the US itself more than 60 percent of the adult population face this health problem and associated increased risk of various other diseases because of this condition. Clearly urbanization, sedentary lifestyle and modern dietary practices are indicated as the culprits. The problem has reached epidemic size.
Rapid urbanization is going to make it even more widespread a problem. So too is there a booming market for weight loss solutions and products. It is estimated to have crossed US billion annually. Concern, interest and investment have increased in conducting scientific studies into its causes and solutions. All these have resulted in numerous claims and counter claims.

Starvation diet or a crash diet seems to be the spontaneous and immediate response to overweight problem with the intention of burning away the accumulated excess fat. This is grounded on the popular notion that near starvation or starvation is the way to lose weight. Of course, this may look to be alright in the beginning. But when the metabolism declines with near starvation, hunger will increase. There is also the risk of undernourishment and physical weakness. Rather than starve, it is better and safer to increase the frequency of the meals but with lesser quantity of food.
It is generally believed that carb-free diet will make the flab disappear. But then all carbohydrates are not really all bad. Good carbohydrates slow down digestion and are really needed by the body as it makes one feel full for a longer time too. The craving for food declines. Slow digestion is important for weight loss.
The insulin that is released becomes slow while the glucogen burns the fat away from the body. For instance, bread digests fast and is a bad carbohydrate. The weight loss market offers a number of weight loss diet formulas such as the The Atkins diet, 7 day diet, NutriSystem, Anne Collins Weight Loss Program, Diet Smart, Negative Calories Food& Recipes, Beverly Hills Diet and Fit Yummy Mummy. But you will have to find out what you need and whether any of these fulfill your need.
What is more important is to lose weight and maintain the weight. It is important to know what the reasons for your weight gain are. What you need to know also is your food compatibility.
