You : You could look to see if you're leptin resistant. You could assess this with a reverse T3 (liothyronine) test and if it is elevated you like are leptin resistant. If you follow some simple rules how to eat you will be able to activate your uncoupling proteins. Humans have five total but the ones most important for weight loss are ucp 3 and ucp1. Ucp1 is activated by temperature. This is why elite athletes sometime will train in cold environments to shred weight. Mike phelps used this technique to win his gold medals. Sherpa use this too but too when they guide people to everest peak but they offset it by eat straight lard during their ascent to keep their weights up. Take a look at my leptin rx to help you start. Ucp3 is the major one that allows humans to burn calories freely uncoupled from energy metabolism so you can lose weight.

Increase exercise: You may benefit from simply exercising a little bit longer or at a higher intesity. Consider a pedometer to help you keep a consistent track of how active you are.
