For most people, too much weight is too much fat. High triglycerides in the blood are often seen in overweight persons. These triglycerides are the direct result of carbohydrates from the diet being converted by insulin. Increased blood pressure. Carbohydrates do this by changing the brain chemistry.
Carbohydrates increase serotonin, which produces a depressing or sleepy feeling.
IR is also prevalent in persons addicted to alcohol, caffeine, cigarettes or other drugs. Often, the drug is the secondary problem, with IR being the primary one. Treating this primary problem should obviously be a major focus of any therapy. IR sufferers may have other symptoms as well. However, when a person with this problem finally lowers carbohydrate intake to tolerable levels, many if not most of the other symptoms may disappear.
