It's very hard, I've been struggling for years. I'm almost a vegetarian, I still got belly fat when I turned into 40s. A few things helped. Wheat grass, I take one spoon each day. Psyllium works similar to wheat grass. Eat mainly non-starchy vegetables and protein, less carbo, that also helps. Drink a lot of green tea, no sugary drinks. Cutting suguary drinks off doesn't help me lose much weight, however if I add them back I'll gain more fat in a short time. So, that still count.
