Last week was about reading your thyroid labs. This week is about what you can actually do. Johan walks through the full thyroid pipeline - from the brain's TSH signal, to T4 production, to the T4-to-T3 conversion that sets your metabolic rate - and turns it into a practical checklist: the raw materials your thyroid needs, the factors that quietly inhibit it, and why stress and chronic low-calorie dieting push your body into reverse T3, the metabolic brake.
In this episode:
00:00 - Genetics load the gun, lifestyle pulls the trigger: why this week is a checklist, not a lab lecture
04:49 - DM Johan a topic on Instagram - first suggestion in might become next week's episode
06:14 - The pipeline from the top down: TSH, T4, T3, and reverse T3 as the metabolic brake
06:59 - The raw materials for T4 production: iodine, tyrosine, iron, zinc, B vitamins, vitamin D3 with K2 - and why chronic dieting leaves you short on all of them
09:25 - What inhibits production: stress above everything, plus infection, trauma, fluoride, toxins, and autoimmune attack on the thyroid itself
10:37 - The conversion step: zinc and selenium (two Brazil nuts a day), and what shifts T4 into reverse T3 instead - stress, low-calorie diets, inflammation, liver and kidney dysfunction
13:34 - Testing smart: full panels once or twice a year, trends over single numbers, and the free at-home gauge - your body temperature
