Insects and fish for meat were also consumed: until they moved into villages, individuals were only consuming unprocessed and only natural foods. Energy balance theory: states: energy intake = internal heat produced + external work + energy stored, energy is consumed in the diet through three macronutrients: protein, carbohydrate and fat. Examples include rice, wheat, potatoes, natural sugars etc. The obesogenic environment: today"s modern food environment has become engineered to maximize the scale"s as most are processed foods.
