The Dangers Of Fasting For Weight Loss

In a never-ending effort to come up with new angles on fat loss, the health industry has created a slew of fad diets over the years. One type of diet that has gained traction is fasting.

The big problem with fasting, however, is that it can cause some very serious issues especially if you do it for a prolonged period of time. Don't believe me? Here are 6 reasons why you shouldn't be fasting:

1. An emptied liver. What gets emptied from your liver? Carbohydrates that are stored in the form of glycogen. This liver glycogen is responsible for maintaining normal blood sugar in between meals. Without it, your blood sugar will be at a perpetual low.

2. The transformation of muscle to sugar. Without sugar, the brain shuts down. This is one of the reasons diabetes is so scary. When you fast, sugar becomes depleted in your body. In order to prevent death, your body begins to transform muscle tissue into sugar.

3. Vital tissues get burned as fuel. Lean tissue isn't the only thing your body will go after to survive. Proteins in your blood, digestive linings, heart mass and lung mass ALL get burned as fuel. And burning up such vital tissues is probably not the healthiest thing to do.

4. Ketosis. If you fast for an extended period of time, your body will produce ketone bodies to prevent death. Ketone bodies are modified fat fragments that your nervous system can survive on, although not optimal. Thus, you begin to function on inefficient energy sources.

5. No proven benefits. Many people undertake a fast under the impression that there's some type of health benefit. Yet there hasn't been any solid scientific evidence proving this. On the contrary, fasts tend to be extremely unhealthy.

6. Metabolic acidosis. Acidosis is not fun. An immediate drawback will be the inability to exercise with intensity. In fact, exercise will become astronomically painful. You'll also lose an abundance of minerals through urine.

Unfortunately, most fasts are also accompanied by a weight gain rebound. This happens because as you fast your metabolism slows down significantly. Then once you stop fasting, you eat an excess to compensate, but you have a slower metabolism!

Thank you for so clearly laying out the dangers of fad diets, particularly as they can affect people who have diabetes. I've long been an advocate of eating a healthy diet combined with proper exercise as part of a diabetes care regimen.

In my blog at http://www.dentistryfordiabetics.com/blog, I write extensively about diabetes control and it?s relationship to sensible diet, exercise and good oral health care.
