Among adults with body mass index scores greater than 30, as many as 60% may have autoimmune thyroid disease
Even in adults without overt thyroid disease, body weight and visceral fat relate to thyroid levels. A TSH change of 1 unit relates to weight changes of 0.66 pounds for women, and 1.8 pounds for men.
Weight loss resistance is the single most common symptom associated with thyroid disease. Some find that they never had weight struggles prior to the onset of thyroid disease. Others find that thyroid disease greatly amplifies ongoing weight struggles. The specific symptoms include unexpected weight gain, weight loss only with extreme measures, or an inability to lose weight even with extreme measures.
Supplements may help weight loss efforts through a variety of diverse mechanisms. Some mechanisms may not be safe or helpful when weight gain relates to thyroid disease. Others can be more appropriate. These include:
Appetite reduction - decrease the amount of food preferred
Increase NEAT - raise the amount of energy expended through daily activities
Lower inflammation - decrease the amount of inflammatory triggers and associated hormones like leptin and adiponectin
Amylase blocker - decrease the absorption of dietary starch
Lipase blocker - decrease the absorption of dietary fat
Increase hepatic lipogenesis - improve the breakdown of stored fat from within the liver
Raise diet induced thermogenesis - increase the effect of meals on elevating the BMR
