We have all seen or heard of the popular diet and weight loss plans that promise a rapid loss of weight, pounds and inches just melting off, and all in record time. These diets are what we call fad diets. The biggest problem with this type of weight loss plan is that their fat reducing effects are only temporary and in most cases the weight is regained as quickly as it left. Most diets that offer a miracle cure to losing weight or a quick fix for obesity are not only harmful to your body but can also be detrimental to your finances as well.The immense popularity of fad diets has grown even more rapidly as time goes by due to the increase in advanced communication such as television, movies, magazines, tabloids and especially the internet. Our over indulgent life styles that we have all become so addicted to has in many ways been detrimental, especially to our waist lines. Obesity has become a real problem and the desire to lose weight and live a more healthy life often lead to unhealthy methods in our quest to lose unwanted pounds and inches.One of the biggest problems with these popular, rapid weight loss plans is that they tend to limit our natural food choices, such as diets that cut carbohydrates, and increase other food groups such as fats and proteins. The result of this type of unbalanced diet results in rapid weight loss, with most of the loss being in water passed out of the system, often resulting in dehydration. Since the main source of energy for the body is carbohydrates the body begins to burn fat for energy and the natural response of the body is to store fat to prevent starvation, so we start to crave carbohydrates. Craving often leads to breaking the diet and eventually quitting the diet all together and regaining all the weight lost.The best diets are those that allow normal but reduced intake of healthy foods, coupled with a sensible exercise program to increase your metabolic rate. This type of weight loss is better for overall health and tends to become more of a permanent life style. It is better to lose a few pounds a week and keep if off, than to experience a rapid unhealthy weight loss that is usually regained once the fad diet is terminated. This is not only hard on the body but also leads to mental frustration as well.In conclusion, a fad diet may be popular, but beware of the harm they can cause to your body. A healthy diet and exercise plan will take some time and effort but in the long run be more beneficial to overall health.
