I know this is an older post but I wanted to make a suggestion in case you are still struggling with your son's weight.
Eating a diet rich in grains and low in fat and protein is a high-glycemic diet, which can lead to excess weight gain. Little kids needs lots of good fats and protein to build those growing bodies and to utilize the fat-soluble vitamins and minerals from their diets.
I would suggest eating whole-fats in their natural form and cutting out grains as much as possible, focusing on proteins, plants, and healthy fats instead. Eating more fats and protein gives a feeling of satisfaction. Carbs tend to make you want to eat more, and tend to have an addictive quality because of how they affect blood sugar levels.
Vegetarian ideas to replace grains are eggs, whole dairy products, and fish, as well as low-glycemic fruits eaten sparingly and lots of vegetables with pastured butter. Cod liver oil and coconut oil given daily can also help make him feel satisfied and help keep his blood sugar and weight stabilized.
Eating the protein and fat as the first part of a meal helps keep the blood sugar from spiking, especially if starchy foods are to be eaten. I would suggest trying this, too.
I would also suggest reading about diet on Mercola.com or the Weston Price Foundation website. I have learned so much from these sources and they have helped me on my own path to health and wellness.
