Carbohydrate Restriction: A Powerful tool to reverse type 2 diabetes

The inability of the current, low fat, moderate carbohydrate, sugar in moderation, nutrition recommendations to control the epidemic of diabetes points to a need for change. The benefits of carbohydrate restriction in diabetes are immediate and well documented. Carbohydrates in the diet are by far the greatest contributor to blood sugar rises, and as expected, dietary carbohydrate restriction reduces the blood sugar (glucose) profile. (1) Simply put; by reducing or eliminating carbohydrates and focusing on fat, protein, and fiber, you can reverse type 2 diabetes. (2)

As you can see in the image below, dietary carbohydrates cause a much larger spike in blood glucose than protein and fat do. Carbohydrate restriction is a powerful tool, and it is the first and most important component of the American Diabetes Society nutrition guidelines.

Individuals have been able to tape off as much as 150 units of insulin in 8 days on carbohydrate restricted diets!

Low carbohydrate diets are safe, sustainable, and effective. With a well-planned carbohydrate restricted diet, individuals reliably reduce blood sugar (glucose), reduce A1c, reduce elevated triglycerides, lose excess weight, and may reduce or eliminate medications. (1) The foods that can be eaten on low carbohydrate, high fat, moderate protein diets are delicious, satiating, and blood sugar stabilizing. One of the reasons this way of eating works so well is that people genuinely like the food they are eating.

Animal based protein is one of the healthiest foods on the planet and is your new ally.

It’s unfortunate that many well-meaning doctors, dietitians, and other health professionals have condemned animal-based foods. Animal proteins not only contribute to blood sugar stability, they also provide vitamins, minerals, building blocks to neurotransmitters and a variety of cofactors that help our bodies and brains function optimally.

There is sentiment that has been created that “restricting” a certain food group such as carbohydrates can cause one to have a dysfunctional relationship with food.

These statements fail to recognize the impact of dietary carbohydrates on a metabolic level. Many people who have used carbohydrate restriction as a tool of reverse type 2 diabetes find food freedom. They no longer have to worry and obsess about foods, nor do they feel compelled to overeat. Of note, case studies have been written where remission was achieved for severe eating disorders including anorexia and binge eating disorder. (4-5).

Also, it makes sense to question if eating real whole foods such as beef, eggs, butter, and low starch vegetables, while forgoing cakes, cookies, pasta, and sugar filled beverages truly is “restricting.” We’ve come to a crux in society where individuals have been convinced that foregoing foodlike substances that cause harm is a problem. The dietary requirement for carbohydrates in the human diet is zero. (3) You do not need to eat any carbohydrates to live and thrive. Does it make sense that someone with impaired blood sugar should consume highly refined versions of these very things?
