Someone told me this about t3 use and carbs.

someone i dont know how up to speed he was but he said that if im on t3 and im eating 0 carbs that the t3 will be ineffective cause it relies on carbohydrate metabolism to work. so if im not eating carbs that i wont get the full effect of the t3. now i just started on the jpi jones gytomel pills at 75mcgs a day split up 2 in the am 1 pm and im curious to know if this is true. it dosent make sense cause why would your metabolism only be higher when u eat carbs? can someone shed some light on this. if i have to eat carbs can i get away with only eating them before 12pm or something so im not sleeping on carbs and they get burnt off by the end of the day? any advise is appreciated

i believe he was confused. If you are in ketosis your body will stop producing t3-t4, but since youre supplementing it youll be fine.
im pretty sure tyroid hormone is not involved in glucose metabolism.

Negative. Your body does not stop producing thyroid hormone while you are in a keto diet. That's absurd.
 
Your thyroid slows down when on a diet because you eat less, hence the reason for 6 meals a day. Since you have t3 being supplemented how could your thyroid drop? I think he is confused with dnp. Either that or he's just a blabber mouth.
 
I believe your friend was talking about this

Switching to a higher carb, lower fat and lower protein diet is crucial in helping your thyroid bounce back after a cycle. A three-day carb up would be a good idea following a T3 cycle. This study demonstrates how important carbohydrates are for normal thyroid function. (Note: Some people seem to think of carbs as Lucky Charms and toast when there are far better carb choices that won't make you look like the Michelin Man.)


Dietary-induced alterations in thyroid hormone metabolism during overnutrition.
Danforth E Jr, Horton ES, O'Connell M, Sims EA, Burger AG, Ingbar SH, Braverman L, Vagenakis AG.

Diet-induced alterations in thyroid hormone concentrations have been found in studies of long-term (7 mo) overfeeding in man (the Vermont Study). In these studies of weight gain in normal weight volunteers, increased calories were required to maintain weight after gain over and above that predicted from their increased size. This was associated with increased concentrations of triiodothyronine (T3). No change in the caloric requirement to maintain weight or concentrations of T3 was found after long-term (3 mo) fat overfeeding. In studies of short-term overfeeding (3 wk) the serum concentrations of T3 and its metabolic clearance were increased, resulting in a marked increase in the production rate of T3 irrespective of the composition of the diet overfed (carbohydrate 29.6 +/- 2.1 to 54.0 +/- 3.3, fat 28.2 +/- 3.7 to 49.1 +/- 3.4, and protein 31.2 +/- 2.1 to 53.2 +/- 3.7 microgram/d per 70 kg). Thyroxine production was unaltered by overfeeding (93.7 +/- 6.5 vs. 89.2 +/- 4.9 microgram/d per 70 kg). It is still speculative whether these dietary-induced alterations in thyroid hormone metabolism are responsible for the simultaneously increased expenditure of energy in these subjects and therefore might represent an important physiological adaptation in times of caloric affluence. During the weight-maintenance phases of the long-term overfeeding studies, concentrations of T3 were increased when carbohydrate was isocalorically substituted for fat in the diet. In short-term studies the peripheral concentrations of T3 and reverse T3 found during fasting were mimicked in direction, if not in degree, with equal or hypocaloric diets restricted in carbohydrate were fed. It is apparent from these studies that the caloric content as well as the composition of the diet, specifically, the carbohydrate content, can be important factors in regulating the peripheral metabolism of thyroid hormones.

A post cycle crash is inevitable; this is the time when your diet really matters.
