Increase Average Weight Loss When Taking Phentermine
Food: Fueling the body with the right nutrients can intensify the effects of Phentermine. Do not eat less than 1,200 calories per day. Going below this amount will trick the body into thinking that it’s starving, which will result in slowing down the metabolism. Instead, keep the metabolism burning by consuming fresh fruits and vegetables, lean meat and fiber. Non-meat eaters can substitute meat with beans, nuts, and dairy.

Water: Many people taking Phentermine experience fast weight loss during the first week due to water intake. Not enough water will slow the metabolism. Drinking at least 64 ounces of water per day flushes out waste and excess sodium, hydrates muscle mass, and increases the metabolism.

Exercise: Aerobic exercise, such as walking, jogging, or stair climbing increases the heart rate, which burns fat. Building lean muscle mass by doing strength training exercises will keep the metabolism high and melt away fat. Incorporating physical activity into a weekly routine is ideal.
