Personally, I find that the easiest way to get tightened up in a hurry is to follow the Phil Hernon dieting principles. Easily digestible protein like chicken breast or grassfed ground beef(or eggs for breakfast) cooked with a healthy fat source like olive oil, macadamia nut oil, red palm oil, coconut oil or avocado oil and carbs coming from fruit sources like pineapple, strawberries and blueberries. Most importantly, you only eat when you’re really hungry, no Force feeding and no eating until you’re absolutely stuffed. When I clean things up and simplify them to this degree, I feel like I can see the changes happening in my body extremely quickly. It’s so extremely simple too.
