You do not have to diet in the traditional sense when taking PhenQ. You never want to go on a calorie restricted diet for a short period of time. Rather you should follow a sensible eating pattern that is based on frequent smaller meals, high levels of lean protein and healthy fats while restricting your intake of sugary carbs. If you take PhenQ without following a healthy nutrition pattern you will probably be disappointed in the results you achieve. Remember. PhenQ is a supplement to sound food and nutrition, not the main course!
