How to fix body health fast ? I am currently 20 years old , height 5 feet 6 inches and I weigh 49 kg and BMI 18.00 . When I was at home, 0.5 liters per day. I used to eat cow's milk but after coming to Dhaka I don't get cow's milk anymore so I don't eat it. Sometimes I drink liquid milk. The mama of the shop says that there are different types of powdered milk kits available. I am getting dry day by day and the taste in my mouth is less Would it be better to buy powdered milk or liquid milk ?? If it is better, tell me which powdered milk to buy. How can I gain 10 kg weight in 3 months ?? Looking for the right advice to fix my health ???
