But the truth is that not all the diet is suitable for everyone, and what works for one may not work for others. However, there are lots of diets out there to choose the best suitable one for you. Here are some different types of diets that people follow around the world.

However, it destroys certain harmful compounds and bacteria. This diet’s primary intent is to create a rise in energy, reduce inflammation, and lower the number of carcinogens.
