Why Does Insulin Resistance Develop?

Insulin resistance has several interacting causes, and these are not fully understood. Genetics, excess body fat—especially around the waist—and physical inactivity are important risk factors. Some diseases and medicines also contribute. [1]

Carbohydrates are not a single category of food quality: whole grains, legumes and fruit differ from sugary drinks and refined snacks. A normal rise in glucose and insulin after a meal does not itself demonstrate insulin resistance. Overall diet, energy balance, activity and individual health matter. [2]

The amount and type of carbohydrate can be adjusted to individual needs. Meal frequency alone should not be presented as an established main cause of insulin resistance.
