KETO VERDICTLIMIT
Lager is higher-carb than spirits: ~3–4g net per 100 ml (≈10–14g per 12 oz/355 ml). It can fit occasionally with strict tracking, but frequent intake risks knocking you out of ketosis.
Each 100g serving packs 3.6g net carbs, so keep portions tiny or choose a lower-carb swap.

WHY TO LIMIT IT ON KETO
- Possible on flexible keto if portions are small and carbs are budgeted
- Lower carb than sweet cocktails, but higher than light beer or hard seltzer
- Alcohol temporarily pauses fat oxidation and ketone production—plan accordingly
- Primary concern is carbohydrate load; protein/fat are negligible
- Choose drier, lower-ABV lagers to minimize carbs
HEALTH BENEFITS
- Contains small amounts of B vitamins from brewing/fermentation
- Provides trace minerals (e.g., magnesium, potassium) in modest amounts
- Polyphenols from malt/hops offer minor antioxidant activity
- Moderate alcohol may be compatible with some diets, but frequency/portion matter
- Silicon in beer has been linked to bone health in some studies (context-dependent)
- Relaxation/social enjoyment when consumed responsibly
PREPARATION SUGGESTIONS
OCCASIONAL COLD SERVING
Chill and pour into a glass (no ice). Enjoy infrequently at social events while tracking carbs.
LIMITED PORTION CONTROL
Limit to 100–150 ml (≈3.4–5 oz) to keep carbs near ~3.6–5.4g, leaving room for food in your daily macros.
WITH KETO-FRIENDLY FOODS
Pair with low-carb snacks like cheese, olives, or pork rinds to help satiety and avoid carb creep.
SPECIAL OCCASIONS ONLY
Reserve lager for celebrations; choose light beer or spirits/seltzer most other times.
