WHY IT'S NOT KETO-FRIENDLY
- Not keto: very high net carbs (~56g/100g dry) easily exceed daily limits
- Even small bowls (≈40g dry) are ~22g net carbs—hard to fit on strict keto
- If used at all, limit to targeted/cyclical keto around intense training
- Better swaps: chia-seeds, flax-seed-meal, or psyllium-husk porridge
- Pair with fats only if carb-cycling (e.g., heavy-cream, coconut-oil)
- Avoid flavored packets—added sugars push carbs even higher
HEALTH BENEFITS
- Rich in beta-glucan soluble fiber that can support cholesterol management
- Provides minerals like manganese, phosphorus, and magnesium
- Contains polyphenols (avenanthramides) with antioxidant activity
- For non-keto diets, can offer sustained energy vs. refined grains
- Whole-grain choice compared to many processed cereals
- Nutritional positives don’t offset the high carbs for keto
PREPARATION SUGGESTIONS
MINIMAL PORTION (CARB-CYCLE ONLY)
If cycling, cap to 20–30g dry and add heavy-cream, peanut-butter, or coconut-oil to slow glucose impact.
AVOID OR SUBSTITUTE
Swap with keto porridge: warm flax-seed-meal + chia-seeds + almond-milk-unsweetened and a pinch of salt.
POST-WORKOUT TKD
For targeted keto, a small serving immediately post-training may be used strategically—log carefully.
MIXED SEED BOWL
Replace oats entirely: combine chia-seeds, psyllium-husk, and flax-seed-meal for texture and fiber.
