Ketogenesis is a super scientific name, and has a lot of science behind it, which is probably why people call the diet: Keto. Keto is a shorter term for ketosis, a process where living things break down fats to sustain life -- it usually happens during starvation or out of control diabetes. Artificially putting your body into a ketogenic state is growing in popularity.
The Keto Diet is basically, a temporary food restriction program that is high in saturated fat and almost entirely cuts out carbohydrates. Suggestions include having bacon with everyday, meat at every opportunity, and sides of veggies Meal suggestions also often include using both butter and olive oil. Some people follow this diet for months or years at a time.
Your brain and body run on glucose, a simple sugar. Glucose is made from lots of things, but a big source is carbohydrates. Once carbs are converted to glucose it enters the bloodstream and can either be used immediately or stored. Stored, if you’re eating more calories than you’re burning, can mean as fat. People see the Keto diet as a way to cut out carbs, and thus sugar storage, removing a source of fat from the body.
However, even without carbs coming in, the body needs glucose, so once glucose drops to less than 100 grams, the body enters a ketogenic state. The brain needs glucose. “Ketogenic” comes from ketone bodies. They’re another source of cellular fuel, not the body’s preferred fuel, mind you, but an alternative supply for vital organs. This is like an emergency backup system for your body. The ketogenesis kicks in when your body is starved of glucose, starting a lipolytic process that breaks down fat.
