What Hacker News says?
If you haven't heard of it, maybe give MacroFactor a look (not affiliated, just a happy user). It is the only food log and weight tracker that I've used with success. On the weight tracking side, it also requires daily weigh-ins and tracks your trend weight over time. Combining that with the calories you log, it determines your TDEE and adjusts your calories and macros from week to week depending on the goal you wan…

HN discussionProbably relevant for the HN crowd: there's a bunch of very geeky next gen fitness guys that keep up with the cutting edge of fitness research, and occasionally expand it themselves. If you're reading them, this kind of thing is being discussed for years, with new studies just moving the odds a bit in favor of the current hypothesis. Yes, they're very Bayesian, explicitly so. A few names/links, pick and mix as you w…

HN discussionhttps://macrofactorapp.com/body-composition/ Estimates in level of inaccuracy on the high end ranges from ~5% to ~10% If you see your lean mass going up in DEXA, your muscles are getting larger, and you're getting stronger, particularly across a wide variety of exercises where CNS adaptation can't explain the strength gains, they're likely broadly accurate. Mine have all tracked quite closely with what I'm seeing in…

HN discussionI highly recommend this article from the MacroFactor team on this: https://macrofactorapp.com/refeeds-diet-breaks/ Basically their view is that refeeding (aka cycling) probably doesn't do much physiologically speaking, but there may be advantages to adherence when people use diet breaks (typically longer than a cycle or refeed).

HN discussionMost people I know consider me a “disciplined” person. I’m a fitness junkie who has very rarely missed a workout in the last 10 years. I maintain a not-as-strict-as-I’d-like-but-seemingly-better-than-most diet. I prioritize habits that help me or that I enjoy like sleep and reading. There are days I do not want to. There are days when I am tempted. There are days when I am depressed, busy, etc. Things get in the way…
