With the rising focus on health and weight management, many people are exploring diets that help with fat loss and energy balance. Among the most popular are the Keto Diet (Ketogenic) and the Low Carb Diet. While both limit carbohydrate intake, they operate in different ways and deliver unique results.
In this guide, we’ll break down the key differences between Keto and Low Carb, their benefits and side effects, and provide sample meal plans to help you choose the approach that works best for your lifestyle.
Key Differences Between Keto and Low Carb
1. Carbohydrate Intake
- Keto Diet: Carbs are restricted to less than 50 grams per day, forcing the body into ketosis, where fat becomes the main energy source instead of glucose.
- Low Carb Diet: Allows more flexibility, typically 100–150 grams of carbs per day, without requiring ketosis.
2. Main Energy Source
- Keto: Relies heavily on fats (avocado, olive oil, butter, fatty fish) as fuel.
- Low Carb: Uses a balance of protein and fat while moderately reducing carbs.
3. Food Variety
- Keto: Very strict, cutting out most fruits, grains, and starchy vegetables.
- Low Carb: More inclusive, allowing small portions of fruits, legumes, and whole grains.
Benefits and Side Effects of Each Diet
Benefits of Keto
- Rapid fat loss in the first weeks.
- Lower blood sugar and improved insulin sensitivity.
- Enhanced focus and mental clarity for some after the adaptation phase.
Side Effects of Keto
- Keto flu: fatigue, headache, irritability in the early stages.
- Digestive issues like constipation due to lack of fiber.
- Difficult to maintain long-term for many people.
Benefits of Low Carb
- Easier to sustain long term.

- Helps reduce appetite and stabilize blood sugar.
Side Effects of Low Carb
- Possible lack of energy if carbs are restricted too aggressively.

Which Diet Supports Weight Loss Better?
