WHY IT'S NOT KETO-FRIENDLY
- Very high starch: ~37g net carbs per 100g is incompatible with keto
- High glycemic load: rapid blood sugar/insulin response
- Usually fried in seed oils (omega-6 heavy), not ideal for keto inflammation goals
- Easy to overeat due to palatability and large portions
- If craving hits, choose a low-carb fry alternative (see preparation ideas)
HEALTH BENEFITS
- Provides potassium and vitamin B6, but carb load outweighs benefits on keto
- Some fiber if skin-on, yet still very high net carbs
- Energy-dense; not aligned with ketosis or fat-adapted goals
