Keto Diet: Benefits, Risks, and What to Expect
The ketogenic (keto) diet has gained immense popularity for its potential weight loss benefits and other health perks. However, like any diet, it comes with its pros and cons. This article breaks down the keto diet in an easy-to-read, skimmable format, helping you decide if it's right for you.
What is the Keto Diet?
The keto diet is a high-fat, low-carb eating plan that aims to put your body into a state of ketosis. In ketosis, your body burns fat for energy instead of carbohydrates.
How Does It Work?
- Low Carbs: You consume very few carbohydrates, usually less than 50 grams a day.
- High Fat: The majority of your calories come from fat.
- Moderate Protein: Protein intake is moderate to prevent converting protein into glucose, which can kick you out of ketosis.
