What You Need to Know
Kefir is a fermented dairy product made from milk and kefir grains, which introduces lactose into the diet. This lactose translates into carbohydrates, making kefir unsuitable for a strict ketogenic diet that typically limits daily carb intake to around 20-50 grams. The presence of milk as a primary ingredient contributes to its carbohydrate content, pushing it beyond the acceptable range for keto dieters.
For those on a keto diet, it's essential to look for low-carb alternatives that can provide similar probiotic benefits without the excess carbohydrates. Consider options like coconut milk yogurt or unsweetened almond milk kefir, which can offer probiotics while keeping carb counts low. Always read labels and opt for products specifically designed for a ketogenic lifestyle.
