Follow an alcoholic drink with a low-calorie alternative like sparkling water rather than accepting a refill on the alcoholic drink. Alcohol has 7 calories per gram, which is more than carbohydrates (4 calories/g) or protein (4 calories/g). Alcohol can also weaken your resolve and lead to mindless eating. Replacing meat toppings with vegetables can save you 100 calories per meal.
Follow the 80/20 rule and strive to keep 80% of your intake on track, while giving yourself 20% of wiggle room. As pounds falls off, your metabolism changes and weight reduction gets harder. Your body is smart and recognizes when you are not getting what you need to maintain your existing weight. If you continue to lose pounds, your metabolism slows down so that you will survive longer - this is your system preparing for starvation mode. However, as simple as the energy equation is in theory, it is not a perfect science.
