I find my thyroid medication DOES have a impact on my loss (as it does effect your metabolism) and my ketosis state. I am not a scientist but it DOES relate to loss. BUT you should take your thyroid meds at LEAST a month before you make any conclusions. TAKE YOUR MEDS EVERYDAY!! On an empty stomach and at the same time of day. If you are new to thyriod the best advice is patience..It has taken 2 years to get my meds close to right. So make sure and get tested regularly!!

Take care and GOOD LUCK!!
