There’s also the impact fiber has on your gut health. By now you’ve likely heard of the microbiome—the trillions of bacteria that live in your digestive tract. It turns out that a predominance of certain strains of bacteria may encourage inflammation and weight gain, and eating fiber-rich foods can favorably shift this balance. While it’s too soon to say that changing your microbial makeup will prompt weight loss, it’s likely to send a “hey, stop gaining weight,” message.
No matter how many ab workouts you do, they won't help you reduce belly fat. Instead of focusing on spot reduction — targeting one specific area on your body — you've got to train your entire body, fuel up with nutritious foods, and make sure that you're recovering (nope, all-nighters won't help) to lose fat in general. And losing body fat all over means you will be losing some on your belly as well.
"Only doing abdominal-focused workouts, like crunches, won’t help you banish the bulge. Belly fat is simply where your body stores energy, so you need to take a whole-body approach to tackle it. HIIT training (high intensity interval training) is a great way to burn fat and get your heart rate up. Squats, burpees and treadmill sprints are all examples to try."
