The Atkins Diet:The focus of this diet plan is to get rid of carbs from the diet and increase consumption of as many proteins and fats. Similar to the Dukan diet, this diet is also split into four phases. In the induction (first) phase 20 grams of carbs is consumed per day for two weeks. In the remaining phases, the aim is to re-introduce healthy carbs. Being a low-carb diet, it can be instrumental in eliminating belly fat.
