What can accelerate the speed of your bodyís metabolism?
Well the best thing is thyroxin, the hormone that comes from your thyroid gland in your neck. This binds to your DNA in different cells in the body and it turns on various genes to up your metabolic rate. If you have too little thyroxin, you become hypothyroid and you get very cold, you tend to put on lots of weight, you can get your muscles feeling very weak, itís hard to think straight, and have no energy. Pretty much the reverse happens if you have too much thyroxin, hyperthyroidism.
