Avoid wasting calories on alcoholic beverages. The average alcoholic drink contains 150-200 calories per glass. Indulge in just 2-3 drinks and you’ve drunk the equivalent calories of an entire meal. If you partake in these beverages, choose wisely. For example, instead of having a full glass of wine, try mixing half a glass of wine with sparkling water or with a diet cola. This will help cut your calories in half.
