What Is the Keto Diet?
The Keto diet (short for ketogenic) is a low-carb, high-fat eating plan designed to put your body into a state called ketosis. In ketosis, your body switches from burning carbs for energy to burning fat.
| Macronutrient | Percentage of Calories |
|---|---|
| Fat | 70–75% |
| Protein | 20–25% |
| Carbs | 5–10% (usually <50g/day) |
When carbs are low, your liver produces ketones, which become your body’s main energy source—especially for your brain.
🔥 How the Keto Diet Helps with Weight Loss
Here’s how keto supports weight loss:
- Reduces hunger – Fat and protein are more filling than carbs
- Burns fat for fuel – Especially stored body fat
- Lowers insulin levels – Helps the body release fat
- Reduces water weight – Fewer carbs = less water retention
Many people see quick initial weight loss in the first 1–2 weeks.
