Body fat question.

What % of bodyfat and how much muscle are ideal for longevity. Is having more muscle always better with sarcopenia draining us of muscle until end of life? And what % bodyfat should we should for, are there any cognitive declines etc with greater obesity?

What is the best way to measure body fat?

Can you talk about different ways to measure body fat %? Like is a $20 handheld device off of Amazon, the same or about the same as a $150 device? Or is it best to go to a lab or something to measure body fat %?

Insulin Resistance

Is insulin resistance reversible? If so, what type of protocol would achieve this? Recently found out through an insulin assay that I have insulin resistance. Not enough to be prediabetic, but it feels like I’m on the path to metabolic syndrome. I know I can manage it through low carb, exercise, and fasting. But I’m wondering if it’s possible to eliminate it entirely?

What are your thoughts on heat therapy?

Can cold therapy help reduce delayed onset muscle soreness (DOMS)?
