Weight gain is not just about eating more; it’s about eating right. The first step in your weight gain journey is understanding your basic calorie requirement.
For most people, this can be calculated as – 35 calories per kilogram of body weight per day.
For example, if you weight is 60 kg, your basic calorie requirement would be – 60 × 35 = 2,100 calories per day.

To help you hit your calorie surplus easily, we’ve curated three nutrient – rich homemade shakes. These shakes are high in calories, easy to digest, and incredibly tasty, making your weight gain journey enjoyable.
