The Keto Diet

The Ketogenic Diet, commonly known as Keto, has surged in popularity as the latest wellness craze, captivating Silicon Valley elites and celebrities alike—from Kim Kardashian to Halle Berry, who credit it for maintaining their svelte figures and vitality. The diet’s premise revolves around drastically reducing carbohydrate intake (yes, even fruit!) and prioritizing fats, a shift proponents claim fuels weight loss without the gnawing hunger pangs. How does it work? By slashing carbs, the body enters a metabolic state called ketosis, where it pivots from burning glucose to efficiently converting stored fat into energy. During this process, the liver transforms fats into ketones, molecules that serve as an alternative fuel source for the brain. Beyond weight management, studies suggest the Keto Diet may significantly reduce blood sugar and insulin levels. Together, these effects—elevated ketones and stabilized metabolic markers—are linked to potential benefits such as enhanced mental clarity, improved energy, and better metabolic health.
