I comply with this rule because at home, we focus more on feeling full than taking pleasure in the taste of the food which makes my family and I very energetic and lively. Berkeley Wellness also refer to this in their "14 Keys to a Healthy Diet". They advise that we should check serving sizes, especially when choosing to eat higher-calorie foods. When my parents prepare a meal, they always serve us in small or medium sized plates that way there is an illusion of enough food on the plate, when in reality it's most likely less than we might think. Additionally, my parents' home cooked meals are almost exactly enough for the entire family and rarely are there ever leftovers. This is because my parents consider the serving size for each of us and they nearly never allow seconds, unless it's on special occasions such as Thanksgiving and Christmas, but even then, they have to consider it. It allows me to be aware of the portions for protein, vegetables, fruits, grains and dairy and consume all the possible nutritions I can and I don't have to frequently buy myself new clothes because I consumed too much calories that I can't burn off.
Moreover, most of my family's garden is vegetables and edible plants such as parsley, sage and mint. This brings us to Pollan's sixth rule which is "eat mostly plants, especially leaves" (Pollan). Berkeley Wellness also support his claim by declaring that eating plenty of produce is a healthy and necessary to a diet because "the nutrients, fiber, and other compounds in these foods may help protect against certain types of cancer and other diseases" ("Keys to a Healthy Diet"). While, no evidence is provided to support either of these claims, it is safe to assume that eating any type of vegetables is beneficial to your health and well-being. The garden also complies with his rule in that we should know what we are consuming and putting in our bodies.
