hi there thanks for asking on HCM, you can continue with the banana almond shake it is healthy it gives you both protiens and carbohydrates. you can take 5 small meals per day instead of 3 regular meals. take fresh fruit juice atleast once daily, a glass of milk in morning and evening is good and also have dry fruits and nuts along with your regular diet. drink lot of water. dont take bad fats like cheese and butter.workout in gym regularly for atleast 30 mins.eat healthy and stay healthy.
