I am an 18-year-old male currently living in Kota. My weight is very low, only 37kg, and I feel like I am losing more weight recently. I want to gain muscle and reach a healthy weight, but I have a very low appetite. I am a student on a tight budget. Please suggest if I need any blood tests (like
thyroid or CBC) to find the cause of weight loss, and recommend a high-calorie diet plan that a student can afford. Also, is it safe for me to take Ayurvedic weight gain supplements?
