South Beach Diet What is the CML? It is the total number of calories you need to consume each full day to maintain your CURRENT fat . Lets claim your CML is 2608 calorie consumption for your current weight. To start losing weight, change your daily calorie consumption to a value significantly less than your present CML (target around 500 calories not as much ). The decrease will trigger your body to find the missing calorie consumption from surplus fat to make an effort to maintain your current excess weight at that activity level. You should start seeing weight loss the primary week, if not reduce your calorie intake somewhat more and/or increase your activity level. The additional increase in demand for calories begins eating apart at your body fat.
