If you've been following a healthy diet and exercising for 7 months and have only lost 8 pounds, I strongly suggest that you make a visit to your doctor and have her/him run some simple blood tests to make sure you don't have hypothyroidism (under active thyroid gland). Weight gain, or inability to lose are prime symptoms of hypothyroidism. Others include constipation, cold intolerance, fatigue, hair loss, acid reflux/GERD, puffiness in the face (especially around the eyes).
The blood tests you need are Free T3, Free T4 and TSH.
What are some good natural supplements to eat or drink??
