The latest weight loss fad is the Keto diet, with Kim Kardashian and Halle Barry both supposed advocates.
The premise is that by banishing carbs, including fruit, and consuming fat the dieter will lose weight without suffering from hunger.
The diet has a history of scientific backing, with doctors advocating such a diet for epilepsy for almost a century. The diet is also considered promising for people suffering from Type 2 diabetes. But this diet is pretty much the Atkins diet rebranded. That and other low-carb plans weren’t very effective, and there’s no reason to think that the keto diet will be any different.
To understand the premise underlying the diet, you have to understand how the body turns food into energy. Glucose is our primary fuel, and it comes from carbohydrates in bread, fruit, potatoes and similar foods. If our glucose gets too low, we could die. Moreover, the body can’t store that much – just enough for a few days. Cut the carbs and you have to find some other fuel. One way to fuel the body is through ketogenesis.
In this process, the liver breaks down fat into an energy source, ketones. Organs can then use this substance instead of glucose for fuel. Once the process begins and the body is in ketosis, the body increases burning fat. If you eat less than 20-50 gram of carbs per day, you can start the process. On the keto diet, people get 5% of calories from carbs, 15% from protein, and 80% from fat.
What that means is that you have to eat mostly meat, eggs, cheese, butter, fish, oils and vegetables. Sugar, bread and other grains are a no go. And if this sounds familiar, it’s because we’ve been there, done that with the Atkins Diet. Keto advocates claim that the diet creates a metabolic advantage that will burn up to ten times more fat and an additional 400-600 calories per day.
This is due to what some experts call the “carbohydrate-insulin hypothesis.” Carb consumption boosts insulin production, stimulating hunger and prompting the body to store fat and burn fewer calories. By replacing carbs with fat, you can quell hunger, increase the calories burned, and get rid of fat.
