Eat A Cool Breakfast
You can keep your core body temperature as low as possible by eating a cool breakfast with foods that will produce a low thermogenic effect. Some people like to eat a plain bagel with peanut butter on it, and while that’s fine, it’s going to be a little harder to digest—and therefore have a higher thermogenic impact—because of its fat content. Drinking a cold smoothie or eating chilled low-residue fruit (grapes, cantaloupe, plums, apricots, melon, peaches, watermelon, applesauce) will help keep your core temperature low. Eating a piece of white toast with jam on it is OK, but avoid raw and dried fruits, raisins and berries and prune juice.
