The Basics of Weight Gain and Nutrition

Before we jump into the list, it’s essential to grasp the basics of weight gain and nutrition. For healthy weight gain, you need to consume more calories than your body burns in a day—a state called a caloric surplus.

While carbs, proteins, and fats all provide calories, some people may opt to focus more on fats and proteins, particularly if they’re following a low-carb diet.

Understanding High Calorie, Low Carb Foods

High-calorie, low-carb foods are rich in healthy fats or proteins (or both) and contain fewer carbs. These foods can help achieve a caloric surplus needed for weight gain while keeping carb intake low.

However, it’s still crucial to ensure a balanced diet by also consuming adequate fiber, vitamins, and minerals.
