Keto vs Low-Carb: Which Diet Wins? (UK)
Both diets reduce carbs, but only keto restricts them enough to shift your metabolism into ketosis. The right choice depends on how strict you can be — and how much you love bread.
Feature Comparison Table
| Feature | Keto | Low-Carb |
|---|---|---|
| Daily net carbs | Under 20–30g | 50–150g |
| Enters ketosis? | Yes | No |
| Macro split | 70F / 25P / 5C | 40F / 30P / 30C |
| First-week loss | Often 4–10 lb (water) | 1–3 lb |
| Sustainability | Lower for most | Higher for most |
Comparison Verdict
Keto produces faster early results and suppresses appetite; low-carb is easier to sustain long-term. Both work if you stay in a calorie deficit.
