The hottest Fasting Substack posts right now

A 6‑day mostly water fast (with diet soda and limited energy drinks) was used more as a metabolic diagnostic than a reliable weight‑loss strategy, and it only extended fasting tolerance by one day versus a prior attempt.
Thermogenesis fell dramatically during the fast, causing extreme cold sensitivity even indoors and while bundled up, but normal warmth and heat production returned quickly after refeeding.
Weight loss from the fast was modest and rapidly regained, so it didn’t produce sustainable fat loss; the slight improvement in tolerance might be from apple cider vinegar, longer linoleic‑acid reduction, or lower caffeine, but the cause is uncertain.

Adding a cream sauce on top of a high‑cream diet didn’t produce fat loss — weight stayed around 214–215lbs and the trial was stopped early because of confounders and life logistics.
A sudden, intense protein‑hunger episode occurred about a week in and only settled after eating substantial protein, showing protein‑leverage can trigger strong, hard‑to‑satisfy appetite at surprisingly low protein intakes, especially when activity, illness, or injury raise needs.
Emulsifying rendered tallow with cream made the food much more palatable and allowed near‑infinite fat intake, creating a major caloric confounder that likely masked any effect of the sauce change.

The concept of a Fasting-Feeding Reset involves stacking supplements to optimize both fasting and feeding states for tissue health.
Fasting is not suitable for everyone, especially pregnant/lactating women, children, or those with certain medical conditions.
The fasting-feeding reset approach aims to clean up damaged tissue during fasting and rebuild healthy tissue during feeding for immune system improvements.

Vitamin D activity may be better understood by measuring both 25(OH)D and 1,25(OH)2D due to their different strengths in activating the VDR.
Fatty liver reversal progress can be seen in weeks with effective approaches, but the timeline varies based on individual factors.
Prefer CGM results over HbA1c to assess diabetic status due to confounding factors affecting HbA1c accuracy.

Dry fasting for 48 hours felt easier than expected. The experience didn't match the scary stories I'd heard online about serious difficulties.
I lost about 5-7.5 pounds after the dry fast, mainly due to water weight. It was surprising how quickly the weight dropped without eating or drinking.
This experience made me more interested in trying dry fasting again. It seems less daunting now, and I have noticed that many people are exploring it more as a way to lose weight.

Experimented with a 'fat fast' by lowering protein intake and increasing fats
Lost 10.7lbs in 14 days by following a specific diet regimen
Considered factors like potassium supplements, workout routines, and PUFAs in the weight loss journey

Iron may play a role in post-COVID fatigue and hair loss, but indiscriminate supplementation is not recommended. Instead, focus on reducing inflammation, testing iron levels, and supplementing strategically if needed.
Some argue that COVID may lead to cellular iron overload and that copper, not iron, could be the solution. Exploring these contrasting perspectives can help in addressing iron trapped by inflammation.
Consider a holistic approach to releasing iron trapped by inflammatory processes, which may be beneficial for individuals experiencing long-COVID symptoms.

Christians can follow a paleo diet while maintaining their faith and beliefs.
The paleo principle should be treated as a heuristic, not a rigid diet or dogma, to guide personal health choices based on ancestral eating patterns.
Orthodox Christianity provides insights on the relationship between faith and reason, fasting practices, and the heart as a tool for seeking God.
