Here are a few tips to get a flat stomach without much exercise!

1. Eat slowly to avoid swallowing extra air that may cause bloating.
2. Avoid those carbonated drinks.
3. Be aware of some particular food which may cause bloating. Those are pulses, dried fruits, broccoli, cauliflower, cabbage, sprouts, peppers and citrus fruits, e.g., oranges and lemon.
4. Reduce your salt intake, either with food or without of it.
5. Avoid raw vegetables, especially carrot. Try to take them in boiled form.
