Thyroid & Metabolism

Chronic low-grade inflammation can drive weight gain by disrupting insulin and leptin signalling. Here’s the mechanism, and what functional testing reveals.

Reverse dieting means raising calories gradually after a long diet. How it may ease adaptive thermogenesis and reduce the risk of rapid weight regain.

TSH can rise after starting iodine. Why that shift is often the thyroid axis recalibrating rather than a sign of harm, and when a rise is worth reviewing.

Metabolic adaptation is why weight loss stalls: your body burns fewer calories than predicted. What drives the plateau, and what may help you past it.

HIIT is generally more accessible and better tolerated, while sprinting…

Author: Rohan Smith | Functional Medicine Practitioner | Adelaide, SA Quick Answer Fasting and starvation are physiologically distinct states. Therapeutic fasting is a controlled, voluntary period of food abstinence during which the body shifts from glucose metabolism to fatty acid oxidation and ketone production, activating adaptive processes such as autophagy. Starvation, by contrast, occurs when…

Can’t lose weight despite diet and exercise? Thyroid conversion, insulin and leptin resistance, cortisol and gut bacteria can each block fat loss.

Signs you may not be converting T4 to T3, why TSH alone will not show it, and which thyroid markers reveal conversion problems and autoimmune activity.

Your metabolic set point is defended by the hypothalamus through leptin and insulin. How adaptive thermogenesis lowers your burn rate, and how to work with it.

eTRF, or early time-restricted feeding, means eating inside a 6-8 hour morning window. Research suggests it may improve insulin sensitivity and blood pressure.
