From a physical health perspective, flexible dieting is a great way to get in shape and ensure you’re getting the proper nutrients you need without any guesswork. The precision required means that if you set up your numbers and food sources properly, you can give your body exactly what it needs to feel and look good day after day. Other diets tend to take a broad approach; they ask you to eliminate certain food groups, try to control your portions, and hope for the best. Sometimes this works and sometimes it doesn’t, but these other diets don’t always ensure you’re actually getting the right nutrients.
