To begin with, we must understand that this regimen is very fundamental in nature. First, we must first identify our current eating habits. What do we eat on breakfast, lunch, dinner and in-between if there are any? Second, which among those items can we reduce our consumption? Can we instruct ourselves that instead of eating a full cup of rice and can we eat half instead? If it is done religiously then we can observe that our body is slowly becoming leaner by quite some time.
Third, which among our consumed foods can be substituted with much healthier alternative? For example, instead of using animal-based cooking oil perhaps we can replace it with plant-based oils such as canola, soya or corn. Another example would be using tofu instead of using meat products as a source of protein.
If you can do these, then there is no need for you do to calorie counting. However, to maximize its full potential you must also equip yourself with exercise and other healthy living habits such as non-smoking, etc.
Moving forward, four day diet plan does not require you to become a vegan (vegetarian). However, becoming such would be better as well. The four diet plan resembles or serves as our reminder to consume foods as prescribed in the food pyramid. The right foods and in proper proportions are the only things that we need.
