Dial in Your Diet Jade Jenny, head CrossFit coach and owner of Champlain Valley CrossFit says that "reducing belly fat ultimately comes down to how you eat." You can't exercise away a bad diet, and abs truly are made in the kitchen. In order to lose belly fat, you need to reduce your overall body fat percentage by dialing in your diet, eating whole foods, ditching the junk, and creating a calorie deficit.
