And to expand on that... The free T3 level also needs to be watched. If That level isn't also within the upper part of its range, weight loss will be much tougher. Not everyone can produce enough T3 from the T4 they take. If they aren't, a T3 med has to be added to the regimen.
Also, at the very beginning of treatment, old symptoms might worsen and/or new ones might appear. Weight gain is one of the things that could go awry during early treatment, and it should return to normal once levels are optimal and stable for a few months.
It's my belief that people who say the "med makes me gain weight" have a lot of other issues going on. Weight gain is not solely dependent on thyroid levels, so it can't be solely blamed on that. Someone who has begun treatment and is feeling otherwise better could be eating more because their appetite has been re-awakened, or they now have the energy to prepare meals when they could barely get out of bed before, or because the hypo-induced depression is lifting.... possibilities all. Just being in treatment is no guarantee that excess weight will suddenly begin melting away... Just as being hypo is no guarantee that everyone who has it will gain weight. It's just a much more complicated subject than to generalize like that.
