Wellness Wednesday for April 17, 2024

The Wednesday Wellness threads are meant to encourage users to ask for and provide advice and motivation to improve their lives. It isn't intended as a 'containment thread' and any content which could go here could instead be posted in its own thread. You could post:

  • Requests for advice and / or encouragement. On basically any topic and for any scale of problem.

  • Updates to let us know how you are doing. This provides valuable feedback on past advice / encouragement and will hopefully make people feel a little more motivated to follow through. If you want to be reminded to post your update, see the post titled 'update reminders', below.

  • Advice. This can be in response to a request for advice or just something that you think could be generally useful for many people here.

  • Encouragement. Probably best directed at specific users, but if you feel like just encouraging people in general I don't think anyone is going to object. I don't think I really need to say this, but just to be clear; encouragement should have a generally positive tone and not shame people (if people feel that shame might be an effective tool for motivating people, please discuss this so we can form a group consensus on how to use it rather than just trying it).

Yeah, the meta shows no effect on all cause mortality - but that's not the question we're discussing. I only brought it up since you responded to the graph of mortality outcomes rather than weight outcomes.

To stop gaining weight, decrease mono-unsaturated and poly-unsaturated fat.

In fact, the meta shows that substituting unsaturated for saturated fats reduces weight and there's no association If the studies were actually controlled metabolic ward studies, they'd probably show no effect with isocaloric diets.

According to the PUFA hypothesis, it's more like a cliff than a gradient. Humans naturally eat around 4-5 gr a day of PUFA without seed-oil or mono-gastric animal sources. This study has the Sat Fat group get twice that.

This seems like an extremely specific and unusual claim, perhaps a result of undeniable studies chipping away at the upper limits of what people can defend. We definitely shouldn't privilege weird rat studies over human ones to defend this claim. Linear relationships should be the default assumption.

Losing lean mass when losing weight can actually be quite good, as you don't want a lot of extra skin hanging around.

The lean mass lost is not skin, it's internal organs, muscle mass, water weight, etc. The amount of skin remaining after weight loss does not depend on the diet.
