Low carb diets are still popular. Low-carbohydrate diets or low-carb diets are dietary programs that restrict carbohydrate consumption usually for weight control. There are many different versions of the low-carb diet all of them have one thing in common a very strict reduction in the consumption of carbohydrates.

According to many experts, most overweight people became overweight due to a condition called hyperinsulinemia — elevated insulin levels in the blood. When you eat a high-carbohydrate meal, the increased blood sugar stimulates insulin production by the pancreas. Insulin is the hormone that allows blood sugar to be used by the cells. However, a side effect of insulin is that it also causes fat to be deposited, and it stimulates your brain to produce hunger signals. You eat more carbohydrates, and the cycle repeats.
Restricting the intake of carbohydrates puts a halt to this vicious cycle. When you restrict your carbohydrate intake, your insulin levels decrease and the levels of glucagon increase. Glucagon is a hormone that causes body fat to be burned and cholesterol to be removed from deposits in the arteries.
If you severely restrict carbs, your body goes into a state of ketosis–burning fat with the subsequent production of ketone bodies in the bloodstream.

Low carb diets are not only safe, but if followed properly, can be heart-healthy. Low carb diets have several good effects on cholesterol. Low carb diets are designed to prevent blood sugar levels from spiking and causing the overproduction of insulin a hormone that helps convert carbohydrates to body fat. The first carbohydrates you need to add back to your diet when you move beyond Induction are more vegetables, then seeds and nuts, then berries and then if you are still losing legumes and grains. Low carb diets are easy for people who enjoy meats and cheese, but it may be tough for a vegetarian to go on a low carb diet. In general, on a low-carb diet it is not necessary to count calories.

Advantages of Low carb diets:

* Sustained weight loss
* Stabilized blood sugar (especially important for diabetics)
* Lower insulin levels
* Better blood lipid profile (low cholesterol)
* Lowered blood pressure
* More energy

Low-carb dieters dropped an average of 26 pounds, compared to an average of 14 pounds shed by the low-fat group. The low-carb group had decreases in blood fat levels and increases in good cholesterol than their counterparts on a low-fat diet. Low-carb diets are very popular for their quick results.

Carbohydrates are not bad, only some of them are, and should be eaten in moderation. Finally, there is the personalized metabolic typing diet, which is using your body’s intuition to determine the best combination of fats, proteins, and carbohydrates for your optimal health. Carbohydrates are found in almost any kind of food, even vegetables — not just bread and pasta. Carbohydrates including bread, pasta, rice, cereals, milk, most fruit and any sweets usually provide over half of people’s daily calories. On a low-carb diet, however, carbohydrates are limited or avoided, thus leading to a significant reduction in calorie intake.

Low-carbohydrate diets probably result in weight loss by forcing your body to burn fat for energy. The body would rather burn carbohydrates- either from blood sugar or stored carbohydrates in your liver and muscles. Low-carbohydrate diets are essentially very simple. By restricting carbohydrate intake, cravings for carbohydrates will over time subside, resulting in a lower food consumption and weight loss.

In the first week of a low-carbohydrate diet a great deal of the weight loss comes from eliminating water retained in the body. However, this is a short-term effect and is entirely separate from the general weight loss that these diets can produce through eliminating excess body fat.

Low-carb dieters should also be aware that low-carbohydrate and low-calorie are not the same thing, just as low-fat and low-calorie are not synonymous.
No study has demonstrated that such diets are safe or effective for long-term use. But following a low-carbohydrate diet under medical supervision may make sense for some people .
