When we switch from an animal-based diet to a plant-based diet, it becomes difficult to track our calories. It is because plant-based foods are not as rich in calories as animal-based foods. Hence, if you are eating smaller portions as you did in your earlier lifestyle, it is sure to bring down your energy levels drastically. You must ensure that you are consuming a proper 2000 calories diet even while eating a plant-based diet. By not having enough nutrition, you don’t just risk health problems but also increase your chances to abandon your diet and go back to old ways.
