Alcohol doesn’t make weight loss impossible, but it will slow your progress especially if consumed too often. Even if you’re not worried about gaining weight, it will still be calories that could have been allocated more effectively. And over consumption of alcohol will lead to sub-optimal athletic performance.
However, the principle of nutritional contrast—the concept of revving up your metabolism before reducing food intake to create a fat-loss effect—will stay intact regardless of whether or not you consume alcohol. The fat burning effects may be blunted and the overall calorie count of each meal plan will be higher by the amount of alcohol consumed, but it doesn’t mean other changes to your diet have no effect.
More notably, restrictive meal plans, particularly ones implementing carbohydrate restriction, will have their effects more severely blunted by frequent intake of alcohol. Remember, not all alcohol is created equal. Any amount of alcohol works against your weight loss efforts but some forms are much worse than others. As you track alcohol you’ll get a sense for how impactful each type of alcohol is based on its impact on your progress bar. This impact is designed to reflect the effects a certain type of alcohol is likely to have on your progress. Alcohol consumed while on a lower phase will have a greater impact on your progress bar (and body). Always track accurately when you chose to indulge so MetPro can work as designed.
