Over the years, fad diets comprised of non-meat, liquids and fasting have emerged, promising great results within a short time. In most cases, these fad diets all have one similarity, they promise quick and rapid weight loss, with very high restrictions on the types of foods and the amounts recommended daily. No matter what age, these restrictive diets can be dangerous. Recent rankings defined fad diets less nutritious for health reasons and less responsive for long term weight loss.

Paleo Diet

The Paleo Diet is one of the most recent to emerge based on the idea that good diets include meat, green leafy plants and fruits in their natural state. It eliminates processed foods, which may make finding these food sources difficult. The diet is very restrictive and can be confusing to some. The recommendations are sometimes very high in saturated fats, and there’s also the fact that we have evolved somewhat since the Paleo age.

Dukan Diet

The Dukan Diet is another low carb diet, offering a support regime for weight loss. The difficulties are the rules, and the banning of food groups, particularly grains and fruit. For the short term like the other fad diets, it works, as a long term to maintain the weight loss, it’s questionable.

Raw Food Diet

The Raw Food Diet is a vegetarian diet with restrictions for dairy products, meat, and temperatures for cooking foods because the heat breaks down the nutrients. Weight loss does happen, if the diet restrictions are maintained, but there are similar vegetarian diets that accomplish weight loss without restrictions.

Atkins

The Atkins diet has been around for a while, as one of most popular low-carb diets, especially for those looking for quick and rapid weight loss. The concept is to limit the amount of carbohydrates forcing the body to use its own fat for fuel leading to weight loss. Weight can be affect because the body’s fuel is sugar causing a high energy when sugar is available and tiredness when sugar is low. Natural reaction for the body is to store sugar when levels are low preventing weight loss.

Fast Diet

The Fast Diet requires 5 days of normal eating without restrictions and 2 days of fasting with a limited amount of eating. There is a scheduled time frame for eating, which forces the body to fast through the day and replenish in the evening. The goal is to lose body fat quickly, with calorie restriction, eating only proteins and vegetables along with fasting. Although the weight disappears, there are health concerns for some related to intermitted fasting.
