How Carb Blocker Herbs Work
Carb-blocking herbs act primarily by inhibiting digestive enzymes, specifically alpha-amylase, which breaks down starch into sugar. By slowing this process:
- Fewer calories from starches are absorbed.
- Blood sugar spikes are minimized, reducing insulin surges that promote fat storage.
- Satiety increases because slower digestion keeps you full longer.
Scientific research supports the use of these herbs as adjuncts to diet and exercise for weight loss and metabolic support.
