The ketogenic (keto) diet has gained widespread popularity for its potential to aid weight loss and improve metabolic health. Centered around high fat, moderate protein, and very low carbohydrate intake, the keto diet triggers a metabolic state called ketosis, in which the body burns fat for fuel instead of carbohydrates. This shift can significantly support fat loss while preserving muscle mass.
In this article, we’ll explore how the keto diet works for weight loss, its benefits and risks, and how to structure an effective keto diet plan.
What is the Keto Diet?
The keto diet is a low-carb, high-fat eating plan that typically consists of:
70–75% fat
20–25% protein
5–10% carbohydrates
By drastically reducing carbohydrate intake (usually to 20–50 grams per day), the body enters ketosis, where it breaks down fat into ketones for energy. This process can lead to significant fat loss over time.
How Keto Aids in Weight Loss
Reduces Insulin Levels
Lower carbohydrate intake reduces insulin spikes, encouraging fat burning and reducing fat storage.Suppresses Appetite
High-fat and high-protein foods promote satiety, reducing the urge to snack or overeat.Boosts Fat Burning
In ketosis, the body becomes highly efficient at burning stored fat for energy.Improves Metabolic Efficiency
Many people on keto experience more stable energy levels, fewer sugar crashes, and reduced cravings.
