Why This Keto Chili Works
Unlike traditional chili, this low-carb version focuses on high-protein ingredients like ground beef, complemented by nutrient-rich vegetables and anti-inflammatory spices. Celery adds fiber and crunch, while red onions and garlic offer immune-boosting properties. According to research from the NIH, capsaicin from cayenne and chili peppers may help with appetite suppression and metabolism boosting – making this a weight-loss-friendly recipe, too.
