The keto diet is vastly popular at the moment. While there are several variants of the diet, in most instances dieters are required to strictly moderate their intake of foods that are high in carbohydrates. In addition, those on the keto diet are required to up their ratio of protein and fat. The protein helps to keep the person feeling full for longer, and the fat is there to replace the energy source usually taken up by foods high in carbohydrates.
During this process, the body switches from using carbs as an energy source -- and uses fats instead. When this happens, it is said that the body has gone into ketosis.
Recently, Today anchor Savannah Guthrie has undertaken the keto diet, and spoke out about her experience with it -- including why Dr. Mehmet Oz asked her to breathe on him during a function that they were both attending.
Savannah said that she wasn't using the keto diet in order to lose weight, merely as a "little summer experiment," according to her interview on Today.
"I'm not really trying to lose weight or anything, but we might overeat and then you're like, 'I'd like to lose 2-3 pounds, 5 pounds, so I did it and I did like it,'' she said.
The Today anchor was honest in her assessment of the keto diet. While she felt less energy in relation to working out, she was convinced that her mental alertness had improved.
