According to the American Diabetes Association, there are 29 million Americans who live with Diabetes, 90-95% of which have type 2 diabetes, and 86 million more are currently at risk of developing diabetes.
While individuals may be genetically predisposed to developing Type 2 diabetes, a dietary lifestyle that is high in fat (especially saturated fat) could be the trigger for diabetes to rear its ugly head.
Why Does Type 2 Diabetes Occur?
Type 2 diabetes occurs when sugar has a hard time getting into the body’s cells. Blood sugar rises, and the typical recommendation is to limit consumption of carbohydrates (which, ultimately break down into sugar, aka glucose). However, the latest nutrition research reveals another piece of the puzzle that must be included into the conversation.
As illustrated below, when we eat high-fat diet (when fat calories are >20% of total calories and come from meat, dairy, oils, or processed foods) little, teeny, tiny, fat globules may build up inisde our cells. This is different than the type of fat we try to exercise (or wish or pray) away. Ever wonder why there are individuals who are diagnosed with diabetes who are as thin as a toothpick? This is why. A high-fat diet can result in high-fat cells.

How does a high-fat diet affect our cells?
When there is a build up of fat inside our cells, it acts like gum jamming up a lock. Insulin, the key, cannot open the door which will ultimately let glucose into the cell so we can go about our daily lives. Subsequently, glucose builds up in our blood stream. Over time, chronically high blood glucose levels will cause inflammation and can affect the vessels of the eye, kidneys, and limbs. For a person diagnosed with pre-diabetes or diabetes, finding ways to add more fruits, vegetables, whole grains, and beans can totally change the trajectory of your life.
Risk Factors for Type 2 Diabetes
- High fat diet, with calories coming predominantly from meat, dairy, oils, & processed foods
- Overweight – being overweight is the primary risk factor
- Fat distribution primarily in the abdomen
- Family history of type 2 diabetes
- Those who have pre-diabetes or have had gestational diabetes
The Benefits of a Plant-Based/Vegan Diet on Type 2 Diabetes
By reducing fat intake, increasing dietary fiber, and increasing vegetable protein, you can help battle insulin resistance. This could mean blood sugar control and reduction or even elimination of medications.
- Improve blood sugar control more than typical diabetic diets.2
- Aid in weight loss.2
- Help reduce the amount of fat inside muscle cells which resist insulin.2
- When vegan diet is followed, there is a significant reduction in HbA1C (blood sugar normalizes), and this effect is seen further with higher compliance.3
- May be more effective than other diabetic diets in improving cardiovascular risk factors and insulin sensitivity in those with type 2 diabetes.3
- Decreased or elimination of diabetes medication
Nutrition Intervention to the Rescue! Type 2 Diabetes Success Stories
|Jason, Benjamin, and Barbara have all watched their A1C, glucose, and weight plummet and ultimately saved money by decreasing, or eliminating, their monthly medications. For those who have made a conscious effort to eat more meals centered around whole, plant-based foods, they found they have traded the side effects of medication for the side effects of better health.|
|Learning how to use familiar foods in new ways and exploring new foodsis key for moving closer to your health goals. Learning how to read food labels, properly pre-prepping food, and preparing plant-based foods quickly and deliciously can be the difference between being at the mercy of medications and doctors visits or in control of how your money and time is spent.|
