The Keto Diet is well known for being a very low carb, high-fat, moderate-protein diet, where the body produces ketones in the liver to be used as energy. It’s referred to by many different names – ketogenic diet, low carb high fat (LCHF), etc. When you eat something high in carbs, your body will produce glucose as a result of increased insulin levels.
Lipolysis, or the breakdown of stored triglycerides in our adipose tissue, is inhibited by insulin. Muscles will also take up glucose in the presence of insulin and use it directly as fuel, or store it as glycogen. When you restrict carbohydrates, insulin levels are then suppressed, and it stimulates the release of the hormone glucagon. The ratio of glucagon to insulin is an important contributor to ketogenesis – a higher glucagon-to-insulin ratio is required for the production of ketones.
If you find that eating carbohydrates causes large fluctuations in your energy, a ketogenic approach might help control this.
Might kеto Diet help improve your health?
Optimal ketone levels suppress appetite and offer many health, weight loss, physical and mental performance benefits.
For example, Keto Diet is effective at lowering blood triglycerides, which are fat molecules that increase risk of heart disease.
Also, human’s brain and nervous system usually run on glucose. Fueling it mostly with ketones is a whole new world to these cells, and may provide benefit. The main condition this has been studied for is epilepsy, but more research on other conditions is underway.
Is Keto Diet safe? What if I have a medical condition?
It is individual. Some people can sustain a keto diet for years. Others don’t do well on it.
For example, if I eat too much fat and too few carbs, I lose too much weight.
Speak with your doctor about your health condition and goals to decide if a keto eating plan is right for you.
