When this happens a person is said to be in a state of ketosis - characterised by smelly breath (an acetone smell like nail varnish) and side effects such as nausea and fatigue. So you cut out things like pasta, bread, rice and alcohol, yet you eat unlimited amounts of meat, cheese and butter. That's why the Atkin's diet claims to be so luxurious. Do Low Carbohydrate Diets Work? In the short term, most people who go on low carb diets do lose weight and they lose it very quickly. However, the majority of weight loss comes from loss of water and muscle tissue, not fat which is what you need to lose to keep the weight off. Also, if you're trying to lose weight permanently, losing precious lean muscle tissue is like sabotaging your own body. Muscle tissue is metabolically active, and burns calories even when you are at rest. A decrease in the amount of muscle tissue you have will lead to a decrease in the number of calories you need each day to maintain your weight, making it much harder to keep your weight under control when you stop following the low carb diet. So Why Do It? People are attracted to low carb diets as weight loss is very rapid, and we like to see instant results on the scales!

We know, for example, that high- protein diets may be harmful to the kidneys, and are associated with calcium loss, which can result in bone problems. Also, an extreme diet of any kind . Also, when a whole class of foods is restricted, critical nutrients may be lacking from the diet. In a fat- rich, low- carbohydrate diet, the body switches to a form of metabolism that produces ketones. The presence of ketones in the blood system causes the blood to become acidic. Persistent acidity can lead to nausea, muscle breakdown, headaches, irritability, kidney problems and weak bones. Another problem with the low- carbohydrate diets is that they may be deficient in essential nutrients such as calcium, potassium and various vitamins. Discovery Health: A number of books on the market virtually guarantee weight loss simply by adjusting the percentages. Shike: It's true that consuming high- protein or high- fat diets may initially induce weight loss in some people. But what has to be understood is that weight loss is based on calorie restriction . People lose weight not because of the altered food balance, but simply because they are restricting calories. Of course they will lose weight! Now, if you are going to restrict calories ? Nobody needs excess protein and fat in their diets for the many health- related reasons we have already discussed. Although the potential negative effects that I mentioned earlier may take some time to become apparent, it is important to understand that the long- term safety of these fad diets has not been established. Discovery Health: But what about the fact that high- protein diets appear to reduce insulin requirements in diabetics? Isn't this a good thing? Dr. Shike: In the overweight person, increased insulin requirements are related primarily to excess body weight. People who are obese tend to develop an insensitivity to the natural insulin produced by the body . They have developed non- insulin- dependent diabetes (NIDDM), or Type 2 diabetes. Once you reduce body weight to normal levels, insulin insensitivity decreases. The formerly obese person now becomes more responsive to naturally produced insulin. When that happens, he or she requires less supplemental insulin and may not even require insulin injections as long as normal body weight is maintained. Such individuals should still have their blood sugar monitored closely. Discovery Health: Is this also true for people who don't require insulin but might have . Shike: Losing excess weight can help prevent or delay the onset of diabetes. In people who routinely test high for blood sugars, losing weight frequently lowers it, and may even return blood glucose levels to the normal range. Overweight, non- insulin- dependent diabetics will also find the disease under much better control when they lose weight. Discovery Health: So, what you're saying is that high- fat and protein diets do work, but for reasons other than those that are claimed for them? Dr. Shike: Diets work to induce weight loss when they restrict calories. What I have just said about the health and weight- loss benefits of calorie restriction, and the direct relationship between obesity, insulin insensitivity and poor sugar metabolism is nothing new. It's not something that has been.
