A new study has examined the effects of food on typical biological signs of advancing age. Generally, as you get older, you will have elevated levels of glucose, insulin, and triglycerides.
Study participants were given a high-fat, low-carbohydrate diet with an adequate amount of protein. The researchers measured a number of factors, including body weight, fasting serum glucose, insulin, leptin, lipids, and thyroid hormone.
The diet resulted in improvements in the factors related to the aging process. Serum leptin decreased by 8 percent on average, insulin by 48 percent, fasting glucose by 40 percent, triglyceride by nearly 8 percent, and free T3 by almost 6 percent.
