Suggestion: Yes, when walking, consciously tuck in your abdomen, hold your head up and hold your chest out, and your abdomen will be firm.

First, make a weight loss plan that suits you. Eat 8 points full, try not to eat greasy food with high fat, and eat more vegetables.

Vegetables and fruits, drink plenty of water. Do proper exercise after meals and try not to sit. This is necessary. I wish you early success in losing weight.
