To get a flat tummy, fill your plate with green leafy vegetables like celery. Celery is extremely low in calories, full of fiber, and contains calcium and vitamin C that aid in weight loss.
You can drink half a glass of celery juice before eating your lunch or dinner to help cleanse your system. You can also add celery to salad or soup. An additional benefit of celery is that it contains apigenin, a natural compound that reduces the risk of ovarian cancer in women.
