I can't lose weight! i work out 5 hours a week, eat healthy, count calories, and have gained weight instead. also exhausted but negative on thyroid.

Explore thyroid more: There is a good chance you have thyroid issues despite "normal" tests. Most doctors do not correctly assess thyroid issues. Many people who are hypothyroid have a "normal" TSH. Check Free T3 (liothyronine) and Reverse T3 (liothyronine) as well as thyroid antibodies. An integrative doctor will be more likely to assess correctly.
