Keto vs Low-Carb: Which Diet Wins? (Singapore)

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.
