Phentermine is an appetite suppressant used in medical weight loss protocols to help patients jumpstart fat loss and regain control over their eating habits. As a stimulant, it works by activating the central nervous system to reduce hunger signals and increase energy expenditure, making it easier to adhere to a calorie-restricted plan. Phentermine is typically used short-term under medical supervision and can lead to significant weight reduction when combined with lifestyle changes. It’s especially effective for individuals struggling with cravings, emotional eating, or metabolic slowdown, helping them accelerate progress and stay motivated on their weight loss journey.
