keto

"By switching to a keto diet, ketones are produced and used as an alternative fuel source. This may decrease the chance of developing Alzheimer's by preserving the health of brain cells."

"As our study shows, diets like keto that are very high in fat can have serious unintended side effects -- even causing the tumor to grow."

Chaix, Ducker, and Hilgendorf also stress that their study is one specific type of cancer adapting to an obese environment, and that the keto diet may be beneficial for other types of cancer.

Many patients consider the keto diet, which emphasizes high fat and very low carbohydrate intake to trigger a metabolic state called ketosis, where the body burns fat instead of carbs for energy.

Keto diets with lots of protein and fat, while popular, have low adherence and the same weight loss as other diet programmes in the long term.
