A lowered metabolic rate can cause numerous problems and make you feel just plain unwell.
Symptoms can include: slowed thinking, sluggishness and fatigue, easy weight gain and difficult fat loss, lowered immune function, PMS, carpal tunnel syndrome, IBS, fibromyalgia-like symptoms: joint pain, muscle pain; fluid retention/swelling, headaches or migraines. That’s a long list.
Below is a list of things that lower your metabolic rate:
- Fasting and caloric restriction
- Mineral deficiencies
- Excessive T4 (e.g. if you are on synthroid)
- Thyroid dysfunction/disease (which could include – Grave’s, Hashimoto’s, hypothyroidism, sometimes even hyperthyroidism)
- Lowered adrenal function; cortisol output
- Estrogen dominance (too much estrogen compared to other sex hormones)
Notice the first thing on the list is caloric restriction – this means dieting. So if you are dieting and reducing the amount of calories you eat in order to lose weight, you are actually working against your body.
If you suspect or are just curious about your metabolic rate – get an old-fashioned liquid metal thermometer (Geratherm) and check throughout the day to get your baseline. It should be 37C or 98.6F. If your temperature is consistently lower, then you should probably get checked out.
