A plant-based diet can reduce the risk of several of today’s common diseases, including obesity, heart disease, type 2 diabetes, and various forms of cancer (1,2,3). It’s important to get the extra calories from a variety of food groups; protein, carbohydrates, and healthy fats. For example, weight lifting, squats, lunges. Push-ups and yoga will all help you to increase your calorie intake so that you have more energy than you burn. The most important thing is to ensure that you are getting enough protein in combination with some sort of resistance exercise.
