Nonetheless, Fung told Live Science that she thinks the study clearly demonstrates the potential for a ketogenic diet to have a detrimental effect in humans. And, until researchers better understand the risks of those detrimental effects, she suggested that people consider other ways of accomplishing their health goals, such as trying a less-restrictive diet.
On a ketogenic diet, your entire body switches its fuel supply to run mostly on fat, burning fat 24-7. When insulin levels become very low, fat burning can increase dramatically. It becomes easier to access your fat stores to burn them off. This is great if you’re trying to lose weight, but there are also other less obvious benefits, such as less hunger and a steady supply of energy. This may help keep you alert and focused.
