> [on high metabolic rate - very high temps and [[pulse]] - which is a result of low [[thyroid]]] About your high metabolic rate and high temperature: In my teens and twenties, I needed about 8000 calories per day when I was physically active, about 4000 to 5000 when I was sedentary, but after I took [[thyroid]], I needed only about half as many calories. [[thyroid]] is the basic regulator of blood glucose, and it causes it to be fully oxidized for energy, so that it produces ATP efficiently, on relatively few calories. If blood glucose falls, because it's being used very quickly, the body responds with stress hormones, including glucagon, adrenalin, and cortisol. They cause fat and protein to be burned for energy, while in [[hypothyroidism]], glucose can still be used inefficiently for glycolysis, producing lactic acid, displacing bicarbonate and carbon dioxide. This causes mineral imbalances, with effects including cramps and nerve-muscle tension, which produce heat and waste energy. When you first start taking [[thyroid]] again, your tissues will need some extra [[magnesium]], during the time when the dose is increasing, and when the mineral balance is restored your temperature and metabolic rate might decrease a little. Orange juice, [[milk]], and coffee are good for the main minerals, while salting your food to taste. > Supplementing [[thyroid]] can sometimes reduce the rate of metabolism, by allowing cells to retain enough [[magnesium]], which stabilizes ATP. > [WHITE [[SUGAR]] BAD IDEA WHEN METABOLISM IS HIGH?] But sometimes it can lower the stress hormones, so it requires experimenting > I think the mineral and vitamin requirements do increase with calorie requirement. > [Is there ever a time that one would WANT TO DECREASE THE METABOLIC RATE?] When marooned without food, waiting for rescue.
