A shout-out to the Rationalist Team in the Unaging Challenge, for having the highest completion rate of the seven teams after three weeks! https://www.unaging.com/unaging-system-2025/

Streamlined the registration page, and added a field to note that you want to join a Less Wrong team: https://www.unaging.com/unaging-system-2/

Hmm... "Join a LessWrong team..."? Changing from "the" to "a" should make it clear that these aren't the honorable folks who run this website.

Oura also fine. Some of the people in the beta group are using them.

Thanks for the comments. You're right that "will not extend your life" is too strong. I revised it to "is unlikely to significantly extend your life." Given the impact of other factors on longevity (strength training: 25%, aerobic exercise: 37%, walking 12k steps: 65%, 20g nuts daily: 15%), I do feel the reduction in all-cause mortality from weight loss shouldn't be the top priority.

Well, it was a bummer that my research on fasting found out I wasted my time doing 5:2 fasting for the last decade. Welp, I'll just research the next blog on calorie restriction. Everyone knows that's grea...

Dammit. Why did I waste those five years doing calorie restriction before I started fasting?

Dammit. I researched Calorie Restriction, and found there's another five years of my life on a restrictive diet that didn't serve much purpose. Lab rats lie. I posted about it: https://www.unaging.com/calorie-restriction/

Premature death is basically dying before you would on average otherwise. It's another term for increased all-cause mortality. If according to the actuarial tables, you have a 1.0% change of dying at your age and gender, but you have a 20% increased risk of premature death, then your chance is 1.2%.

And yes, please read more on the blog!

I made a thing for adjusting your circadian rhythm for jet lag: https://www.unaging.com/jetlag/

Hello! I'm a health and longevity researcher. I presented on Optimal Diet and Exercise at LessOnline, and it was great meeting many of you there. I just posted about the health effects of alcohol.

I'm currently testing a fitness routine that, if followed, can reduce premature death by 90%. The routine involves an hour of exercise, plus walking, every week.
