Here are a few things to watch out for that I learned the hard way.
Low carb diets can cause:
(1) Dry Eyes – [more].
Tears, saliva, and mucus of the sinuses, airways, and gastrointestinal tract are all comprised substantially of glycoproteins called mucins. Mucins are primarily composed of sugar; they typically have a number of large sugar chains bound to a protein backbone. If, for whatever reason, mucin production were halted for lack of glucose, we would have no tears, no saliva and no gastrointestinal or airway mucus.
(2) High LDL – which you may or may not consider a problem [more]
(3) High TSH – which may be a good thing [more]
“Reduced thyroid levels (TSH levels above 5), for a lean individual following a low-carb diet, may be normal and healthy!”
