Читать книгу The Blood Type Diet Cookbook - Lucy Degremont - Страница 25

If you are exercising and following the diet and you still have difficulty losing weight, it is worthwhile checking your thyroid – a weak point for your O system. Hypothyroidism can also be responsible for chronic fatigue, weight gain and difficulty losing weight, depression, low libido, period problems in women, a weak immune system and many more symptoms. Here is an easy test you can do yourself. As soon as you wake up in the morning and before moving about, take your basal metabolic temperature. Place a traditional thermometer (not electronic) in your armpit for 10 minutes, and remain quiet during this time. Follow this procedure at the same time on three consecutive days (menstruating women should do this on days 2, 3 and 4 of their cycle). A temperature below 36.6°C (97.8°F) on three consecutive days most probably indicates low thyroid function.

Blood tests alone do not always give enough information as to what your thyroid status is. If the blood test indicates low thyroid function, fine. If it is normal according to the lab, then it is necessary to consider your symptoms and your temperature before dismissing low thyroid function. A practitioner who knows about thyroid function would be able to help you determine whether your symptoms point towards low thyroid function. I also recommend Martin Budd’s book Why am I so Tired? He has studied and treated hypothyroid problems for over 20 years.
