| Critiques of caloric restriction (CR) studies include issues with control groups in animal research where these groups might eat more than usual complicating comparisons. Also, CR's benefits could vary based on eating habits and may not apply to everyone. There's a concern that extreme CR can weaken the immune system among other issues like bone density loss etc. The overall impact of CR on health and longevity clearly needs more research to be understood. While its undeniable that some of the strains of mice and fruit flies did live longer, extrapolating that to humans and associating that with "health fasting" is questionable at best. If this becomes a viable technique for human health and life extension it ought to be undertaken in a supervised and managed way with the assistance of health professionals. Not sold as a magic treat-yourself cure for all ailments on the internet. All in all CRL outside of an academic and scientific setting is almost certainly just going to spread dangerous misconceptions about health and our bodies. > "Well fasting is hardly a consumerist conspiracy, as that would be a contradiction." No fasting clearly isnt but most of these "health fasting" diet types also shill other dangerous "health" advice from juice "detoxes" to radioactive "aura cleansers" About that "CALERIE" trial:
"many of them had BMIs that fall in the overweight category at the start of the trial. This means that any health benefits observed cannot be fully decoupled from the weight loss most participants experienced on their restricted diets. It is already well-known that going from being overweight to a healthy weight has a positive impact on the body; however, the trial results do not clearly answer the question of whether metabolic changes due to calorie reduction beyond a normal diet can improve health. Moreover, the trial was too short to determine the long-term effects, good or bad. " https://sitn.hms.harvard.edu/flash/2020/can-calorie-restrict... So like I said above portraying this as somehow proven to be healthy in humans is a vast oversimplification of a complicated field and really isnt related to "health fasting" at all |
I already brought up osteopenia and the effect on the immune system two posts ago. Furthermore, they are discussed at length in 2 of the sources I linked. Yet you repeated this point as if it was something completely new. It contributed nothing to adding further context and moving this particular conversation forward. I also never brought up the CALERIE trial (which btw had an average BMI of 25 and excluded anyone abouve 28); however, I did post a source to a different trial in healthy (normal weight) people, which you didn't engage with. You actually didn't engage directly with a single point of mine.
All in all, it seems I'm just wasting my time expecting a nuanced conversation that I can learn something new from. You're just eager to repeat a memorised script.
