Any ideas of how to speed up the metabolism?

I posted this on the main board but a member suggested that I post it here to see if I get any different ideas. I am curious if anyone has any ideas of how to speed up your metabolism.  I have heard of some people taking a drug called  Cytomel which is a symthetic thyroid hormone you can buy in the internet....has anyone else heard of this?  Suppose to burn fat. I have been exercising and staying within my calories and protein requirements but it seems like I am now starting to gain weight since I am alomost 15 months out.  I am scared I will get back to my old weight if I don't do something now. I eat about 1000 - 1200 calories a day and exercise 5-6 times a week to include aerobic and weight training. Does anyone have have any ideas I really need the help. Thanks,

I am not a pro, but I heard this from an endocrinologist. You metabolism revs up if lean protein makes up the vast majority of your calories. This also happens to be the basis of most quick diets as far as I know.

Michelle: There are a couple ways to increase metabolism, namely aerobic exercise and resistance training that builds muscle mass.  You see, muscle is metabolically more active than fat, which is why men lose weight faster than women ( genetically woman have more fat than men...so unfair isn't it?)!  Since I don't know your height or weight and one's meatbolic rate depends on many factors including medical history, dieting history etc., I can only provide general information at this point.  However, for someone who is exercising 5-6 days per week, 1000-1200 calories per day does not seem like enough calories.  I know the concept that "you have to eat to lose" is a difficult one to get your head around, but think of food as fuel like gas is to a car.  If you don't put enough fuel in your tank, things don't run right.  Your body may be actually decreasing it's metabolic rate to compensate for the lack of calories it needs to function on a daily basis in addition to the calories it is burning during your exercise sessions.   As for Cytomel, this is a prescription drug used to treat hypothyroidism and should only be taken after a person has had their thyroid tested AND the drug has been prescribed by a physician.  DO NOT TAKE THIS DRUG UNLESS YOU HAVE BEEN DIAGNOSED WITH HYPOTHYROIDISM.  Additionally, ordering drugs over the internet without seeing a doctor is a dangerous practice.   If you want more specific information, please consult a registered dietitian who is experienced in WLS.   Best of luck, Melania Behrens, MA, RD eNutritionCare.com
