Phentermine Mechanism: Suppressing Appetite and Boosting Metabolism

Phentermine primarily works by suppressing your appetite and stimulating your central nervous system. It decreases hunger signals, making it easier to consume fewer calories, a crucial factor in weight loss. Additionally, Phentermine increases the release of certain neurotransmitters, further promoting a feeling of fullness and enhancing energy expenditure.

Fat Loss Impact: Boosting Metabolism and Fat Oxidation

When you take Phentermine, it can lead to an increase in your basal metabolic rate (BMR). This means your body burns more calories even at rest. Moreover, Phentermine may enhance fat oxidation, allowing your body to tap into fat stores for energy, a critical factor in weight loss.

Weight Loss Expectations:
