Oh please. To quote your much loved Harvard Medical Journal (https://www.health.harvard.edu/staying-healthy/do-gut-bacter...): 'We are just beginning to understand the role of gut bacteria in obesity, and the science hasn't led yet to treatments that will make it easier to lose weight. However, I believe that day is coming.'
And to quote it again (https://www.health.harvard.edu/staying-healthy/the-truth-abo...): 'How fast your metabolism works is determined mostly by your genes.' and also saying: 'But you can't entirely blame a sluggish metabolism for weight gain, says Dr. Lee. "The reality is that metabolism often plays a minor role," he says. "The greatest factors as you age are often poor diet and inactivity."'. Sure, they then list a number of ways to 'boost it', but they all come back to the exact same tune I have been talking about. Exercise and food (And apparently Green tea. Huh, a 100 cal a day isn't great but isn't horrible either).
So if you know of some great way to control either of them, please link me a journal or paper, I would love to learn more.
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.
that is incorrect, and shows that your level of understanding doesn't warrant the certainty of your comments about weight loss.
