It is not recommended to lose more than 1 pound per week for healthily weight loss. The reason for this has do to with the issues which quick and drastic weight loss can have on your body's metabolism and muscle mass. When you lose a lot of weight quickly, you really need to strictly monitor where this weight is coming from. Is it water weight, body fat or muscle mass? The majority of the time, it unfortunately comes from lean muscle mass and this is exactly what will cause serious issues with your metabolism. Muscle is your body's most potent and active tissue for burning calories and body fat. Its basically your body's "furnace" which you want to always keep burning hot. When someone loses a lot of weight, which usually comes from crash dieting or some other unhealthy way of dropping the weight, the body's lean muscle mass is cannibalized and you lose some of your biggest "power" tissue for keeping a lean body.

The worst thing is when the person finally decides to get off the diet and start eating again. Their calories go back up, but since their BMR (basal metabolic rate) is lowered and they have lost muscle mass, the end result is they pack on the body fat very quickly! Ever heard of the term "yo-yo" dieting. This is the reason why tons of people have issues and hard times with their weight loss plans.

Try and focus on creating a max 500 calorie deficit per day which equates out to an overall 3,500 calories per week (1 pound of body fat). Create this overall 500 calorie deficit through a 250 calorie drop in your diet and another 250 burned with an exercise routine. This is the healthiest way to lose body fat while keeping your muscle mass and having your body run at an optimal level. It will also provide you with a much better plan to permanently keep the weight off forever!
