Many people believe that the biggest calorie income from our body is from carbohydrate. That’s why many people avoid eating food that contains lots of carbohydrate. Well, cutting back the carbohydrates is working especially at the first week. But don’t you know that it’s not a fat loss but water and muscle body loss.

This diet was very popular during the 70s and was popularized by Dr. Atkins. But, after a couple of years of popularity Dr. Atkins' dieting approach fell by the wayside for several reasons. Unfortunately, the low-carbohydrate, high-fat diet is back, and seems to be gaining in popularity once again. Currently, Dr. Sears' book The Zone and another called Protein Power have revitalized the Atkins' diet.

Low carbohydrate diet concept is that a person should eat more protein, more fat and very little carbohydrate. Eating more fat, make you feel full longer, and this helps the person exert more control over hunger.

In the past, people were allowed to eat as much red meat as desired, but had to keep their carbohydrate intake as low as possible. This combination of foods causes a chemical reaction, thereby causing the person to burn body fat at an accelerated rate. It's called a ketogenic diet. The low intake of carbohydrate, coupled with a high-fat diet and exercise causes the production of ketones. Ketones are the chemical residue of broken-down fats in the blood. To be more specific, if insufficient carbohydrates exist, the body begins to mobilize fat to a greater extent than it can use.

It’s not healthy! This is incomplete fat metabolism and the accumulation of acid by-products called ketone bodies, can lead to a harmful increase in the acidity of the body fluids, a condition called acidosis or ketosis.

Still Want to Start Low Carbs Diet? Read This
  1. By reducing carbohydrates you will see a drop of body weight and body fat. However, if you drop them too low while exercising, you could alter your body's T3 levels. T3 is an active thyroid molecule that helps regulate your metabolic rate. Diets low in carbohydrate tend to cause a reduction of T3, which in turn can slow down your metabolic rate.
  2. Losing weight from low-carbs diet is not fat loss but water loss! For every gram of carbohydrate you ingest, about three to five grams of water usually accompany it. By decreasing your carbohydrate intake you naturally drop body water.
  3. During the 70s, clinicians began noticing that people that followed the Atkins' diet regained their weight very rapidly once they ceased the diet. In fact, they found the longer a person had been on the low-carbohydrate diet, the more carbohydrate sensitive they became. Further, when this diet was combined with exercise it caused people to become even more carbohydrate sensitive. Body tends to horde and store the carbohydrates as opposed to using them for energy.
  4. Carbohydrates provide a "protein sparing" effect. Under normal circumstances protein serves a vital role in the maintenance, repair, and growth of body tissues. When carbohydrate reserves are reduced the body will convert protein into glucose for energy. This process is called gluconeogenesis.
  5. Muscle fullness depends to a large extent on your carbohydrate intake. Low carbohydrate levels tend to make muscles lose their density and flatten out. Carbohydrates are a great source of fuel, so not eating enough can lower your energy level and make your muscles feel softer.
  6. Insulin does play a role in fat storage, but it also causes glucose to be shuttled into muscle cells as well. Blood levels of insulin should be as stable as possible, not try to suppress its release.
  7. Low on carbs but high in fat and protein? Remember fat increases your risk of heart disease, cancer, and obesity!
