Diagnosing symptoms [ edit ]
Thyroid - Temperature and heart rate [ edit ]
“Oral or armpit temperature in the morning, before getting out of bed, should be around 98° F [36.6º C], and it should rise to 98.6° F [37.1º C] by mid-morning. […] Healthy populations have an average resting pulse rate of about 85 per minute.” - Ray Peat
Markers of health
Ideal
Before
After breakfast
Temperature
98.6 - 99F 37.0° - 37.2°C
Heart rate
85 - 90 BPM
Underarm/oral temperature and pulse upon waking and midday.
Track daily averages
aim for steady rises with changes.
Post-meal temperature
should rise if metabolism is healthy (fuel burning); if it drops, stress hormones may dominate.

Digestion [ edit ]
Bristol stool chart [ 1] [ edit ]
Quick bowel movements two to tour times a day is generally what is good to aim for.
Urine quality chart[ 2] [ edit ]
Foamy urine is a sign of increased circulation of fatty acids, which is most common after stress. In rare cases, foamy urine may be a sign of kidney issues.

If your hands are warm and you feel kind and energetic, you’re doing it right. If you’re cold and cranky, something is wrong
Ideal

White = SIBO or candida

Defficiencies[ 6]
Body skin [ edit ]
Ideal
Smooth, elastic, without spots
Symptoms
Cellulite = high estrogen, high PUFA
Thinning skin (ungrabable) = low thyroid
Lipufuscin spots (liver spots) = high PUFA, high iron
Yellow skin = liver problems, high keratine,
Cracks, ashy knees & elbows = low vitamin A
Hives, itchiness = high histamine
Melasma = excess estrogen upregulating melanin
Stretch marks = low copper, zinc, and selenium, high cortisol breaks down collagen and elastin,
Ideal
Smooth, elastic, without spots
Symptoms
Bulging veins = high estrogen, especially on the back of the hand

Symptoms
Posture [ edit ]

Cravings [ edit ]
Acidic/sour [ edit ]
your body needs more sodium
Aldosterone imbalance
When sodium drops, your adrenals compensate by releasing aldosterone to retain sodium - but this comes with costs like magnesium loss and inflammation. Simply eating more salt can turn off this stress response.
Premenstrual shift
Commonly trigger pickle cravings in women. Hypothyroid women especially suffer from both sugar and salt cravings premenstrually.
Thyroid function
Aging lowers your thyroid function, and your thyroid deficiency causes you to lose sodium. So the craving in most people is a very biological thing. But you could correct it by correcting your thyroid function, which makes you retain salt efficiently so you don't need to eat so much
The manganese connection
Blood test of pregnant women with pickle cravings showed manganese defficiency.

Iodine defficiency [ edit ]
"The skin test of iodine deficiency is completely unscientific. Iodine is converted to colorless iodide by reductants, including vitamin C, glutathione, and thiosulphate... The test is completely irrational. It implies that the body should be saturated with iodine.” - Ray Peat
Excessive amounts of iodide have been linked to the development of autoimmune thyroiditis in humans and animals[ 8]
Food intolerance [ edit ]
DIY Food Allergy Test [ edit ]
Before suspected allergenic meal, relax consciously and check resting pulse rate
Eat slowly, calmly
Wait 10 mins and check pulse again If BPM increases by
<10, unlikely
~10-14, possibly
>15, likely
Eliminate suspected food and repeat until +ID
Why do a food allergy test? [ edit ]
If you have symptoms of chronic inflammation:
Runny/stuffy nose
Excess mucous/saliva
Red/crusty eyes
Itchy ears
Brain fog/Headaches
Myalgia/Neuralgia
etc.
Rule out food allergies before moving onto expensive mycotoxin/heavy metal etc. testing[ 9]
