Please read the stickies at the top of the board - particularly - Are you new to EF Women's Board - there are some basic questions that you'll get asked anyway -e.g. your current weight, bodyfat, how long lifting, current diet IN DETAIL PLEASE, and such.
Please DO NOT expect to find the ultimate "weight loss supplement" -- your DIET AND TRAINING are what you need to optimize.
Can you please post up IN DETAIL (e.g. meal 1, time, portions, what you ate - e.g 4 oz chicken, 1 c broccoli, etc.). Then it is a really great exercise to put a typical day's meal plan into a food counts program (e.g.
www.fitday.com - its free, online, very easy to use) and it will tell you how much you are REALLY eating - total cals, macro breakdown etc.
It really doesn't tell me much that you are on a hi carb / med protein / low fat diet - are you eating GOOD UNPROCESSED carb sources? ENough good quality fats? Good quality protein? and how much of it.
Also diet is great but if you expect to make progress on a schedule you really need to increase the energy demands on your body & build some muscle mass to help burn fat. 15 min of weights - eh - doesn't tell me much and I have no idea of the intensity - it takes 15 minutes just to get warmed up & start some fat burning. And are you doing any cardio with that?
I don't mean to overwhelm you with questions - but the point I"m making is that it is a combination of 1000% tight & optimized diet and consistent, persistent and intense training & cardio (doesnt' mean you are lifting too heavy for what you can lift & killing yourself on the treadmill -means you need to do tight form, do it intensely and like you mean it, and long enough that your body actually acknowledges it as a demand on its energy sources. And most importantly - "supplements" - a good multivitamin & mineral supplement is great. Other than that, if you want to try a thermogenic of some sort - great - there are lots of over the counter thermos that will give you a little kick in the gym - but dont' expect amazing fat burning from ONLY the supplement. If your diet & trainign arent' consistent by themeselves you won't see anythign dramatic from any supplement.
And please. ... T3 - that's a thyroid medication that is a controlled substance. It will indescriminantly consume both fat and muscle. And it is important that it consumes muscle -many women will say "i dont' care about muscle I just want to lose the fat" - Your body is made up of LEAN MUSCLE MASS, BODYFAT, BONE, and WATER. It very much DOES matter that you have muscle. Women don't produce enough natural testosterone to worry about looking like Arnold Schwartzenegger just because you started lifting weights.
..
Anyway - there's a little more to it than just "im' on a diet, I train some and i need a suppplement." If you can add a little more detail we can help w/ some more specific suggestions
