Yeah, I'll give up. It is quite obvious we won't come to an agreement, though I am still not sure what you actually take issue with. Especially since we obviously both agree that obesity is a big problem and should be tackled.

On metabolism: 1. & 2. seem to indicate that you want to do hormone therapy with triiodothyronine? I don't know how we got to hormone therapy from 'eating healthy food' but sure. If you want to go that far I obviously was wrong in saying you can't change your metabolism. I assumed you meant by doing something that didn't involve something as extreme. Like: 3. Exercise increases metabolic rate. Which I thought was obvious. But yes, I should have expressed myself more clearly by saying 'besides the things we are doing anyways because we are in a fitness thread'. That is my fault and you are right here.

On gut biome: 2. 'Overall, further research on long-term diets that include health and microbiome measures is required before clinical recommendations can be made for dietary modulation of the gut microbiota for health.' 3. is on mice but interesting. 1. Is pretty interesting as well. Still, none of those papers have actual recommendations for the common individual.

I mean I readily admit that there might be some amazing cutting edge academic research that already points to a great new way to lose weight by either increasing your metabolism or changing your gut biome. But I haven't seen it yet and your linked stuff doesn't convince me that it is there yet. Sure, I have never heard about triiodothyronine therapy, but that honestly sounds very, very experimental to me.
