Not eating in the morning is the chief culprit of obesity, and drinking milk on an empty stomach is bad for your health! You can have sugar-free oats in the morning, vegetables for lunch and vegetables for dinner. If you don't eat, you will feel very hungry. If you don't persist, you may eat snacks. Vegetables will not only not gain weight, but also help you lose weight. I wish you success in losing weight, but good health is the most important thing!
