To answer OP (sort of): a lot of ppl lose on keto for two reasons. Increased insulin sensitivity and ingesting fewer calories. It’s not however particularly healthy . Most longevity research favors a plant based pescatarian diet for overall health (which shockingly is not the same thing as weight, through there a correlation) if you can control your insulin production via reduction in high glycemic foods, less frequent eating and increase your fiber intake via diversity of plants, (particularly for gut health), switch to healthier fats (avoid inflammatory oils) and keep animal products lower , keep active daily but it can be moderate , then this is generally for most people a recipe for health span. So yes carbs are not the devil
but the right carbs. And you don’t need to load up on protein to make up for it. I used to eat a ton of protein but in fact I think it can adverse impacts long term (so you really want to stimulate growth all the same? Same growth factor that builds muscle feeds tumor growth). By the way the centenarians around the world war like this, exercise and get good sleep. One addendum is also that we all have different (and changeable) microbiomes which impact how we react to different foods. So this is both why some people do better in some diets than others .. BUT the way to create a healthy micro biome with advantageous microbes for metabolic and other kinds of health seems to be by eating lots of plants, some fermented stuff.’ and avoiding processed fats, sugars and starches. This is my bigggest issue with super keto /carnivore diets.
Once I started reading about longevity, science backed research on healthspan I shifted my focus from weight to health. I feel better than I have In a couple years and am happy with my smack in mid range of normal
BMI.
Op here - thank you for this thoughtful post. I’m definitely at the stage of life where I’m focused on feeling healthy and strong. I’m not striving to be super skinny and am only 10 or so lbs over a comfortable weight for me. Maybe it’s more the bloat I’m contending with that’s uncomfortable. Sounds like I need to read more about gut health and inflammation.
Could you direct me some of the resources you’ve read?
Gladly! I actually started down this path because of ongoing GI issues: low absorption of nutrients (chronic low ferritin, and other blood markers); endless bloating and burping, signs of gut inflammation (blood/mucus in stools, etc). Without going too far down the rabbit hole of IBS, gut/brain microbiome, etc....I ended up listening to a variety of podcass by Rhonda Patrick (Found my Fitness) and reading/learning about research by Valter Longo (USC), Dr. Andrew Huberman(yale), Dr. David Sinclair, Peter Attia, Satchin Panda, Matthew Walker (the Slee p Guru) Steven Gundry. While I dont subscirbe to everythign they say/do/recommend and there are differences of opinion between these researchers, the overall commonalities they share are the following: metabolic dysfunction is a result of a terrible western diet of sugars, inflammatory oils, etc. This changes the gut microbiome in profound ways and the gut microbiome regulates everything from cardiometabolic health to emotional wellness (feel good brain chemicals are produced in the gut!). what these researchers tend to share is the folowing: some form of time restricted eating, with many supporting occasional extended fasts for health reasons; high fiber, plant rich, polyphenol rich diet with omegas; low intake of highly processed foods; the importance of sleep and the importance of exercise. Protein requirements seem to be a debate, but overall studies suggest that high animal protein diet is linked to lower lifespan.
I spent a lot of time listening to these podcasts while walking and it has slowly changed everything for me and my family. We eat more vegetables, I eat more nuts and avocadoes (which used to hurt my stomach); I add prebiotic fiber (tasteless) to my am coffee. We eat more legumes than we used to (hummus, blackbean soup, etc) . I switched regular bread for occasional real, high quality sourdough (because fermenetation and its delicious) and whole wheat pasta for white. I don't diet, but I do do IF and occasionally short "fasting mimickingdiet/lowcalories'protein fasts, once every 3/4 months). I tried to take walks after dinner and not eat right before bed. I don't rule anything out, but as I've moved toward a high fiber, high plant, high monounsaturated fat diet, I have found my tastes really have changed. Basically, to sum it up, a whole foods diet prioritizing fish as an animal protein (butI do eat cheese, dairy, chicken and beef, just not daily, I drink red wine and occasionally white but no sweet cocktails unless its super special); moderate exercise, sleep, and I take a couple supplements (iron, probiotics/prebiotics, berberine and omegas). I lost my stomach bloat and fat (esp after my 3rd short fast), sleep better, and my digestive issues are resolved (although I had to go slow on all the fiber at first). Most of all, it seems sustainable, do-able in social and work travel situations, and reasonable.
