I fast, on average, once a week. At least once a month, I try to do an extended fast (2-5 days) to force ketosis. I also do intermittent fasting basically daily (I only eat between 12-8). Been doing this for about 4 years now. Some anecdata: - Fasting > 24 hrs paradoxically gives you an extreme boost of energy and mental focus. I especially love how my olfactory sense is extremely heightened. It's pretty cool and eve…

The biggest benefit I've found to fasting is the sort of reset it provides the digestive system. I've suffered from some pretty frustrating gut health issues over the past few years, and taking a 1-3 day fast every few months significantly improves most of my symptoms. When talking to my doctor, a combination of "reduced inflammation", "digestive rest" and "gut biome health" are all things that get thrown around, but generally "Who knows, but if it works keep doing it" is the general result.

In general with a good diet there is no need to continuously take vitamin supplements.

That also assumes you're getting enough sunlight. A lot of people who work in an office don't.

That's a bad diet compounded by a bad lifestyle. Working in an office does not mean one has to stay indoor all the time and at weekends.

- Even on fast days, make sure you take vitamins (I take Fish Oil, Zinc, a Multivitamin and Magnesium) I have done some fasting recently (water, some water/apple cider vinegar in the morning; coffee, green tea, Ooolong tea), and have a similar vitamin intake (B complex; calcium/D combo; Magnesium; Zinc; Iron; Fish Oil). During the fasting I don't take the Fish Oil, I haven't read anything about it specifically, but j…

- During the fasting I don't take the Fish Oil, I haven't read anything about it specifically, but just assumed Fish Oil was fat that would break the fast. Do you have an opinion on that?

A fish oil pill has around 14 calories and most of the times will break your fast -> Take it after your first meal.

Vitamin D is a fat soluble vitamin and you should take it only after a meal containing some fat. Taking it while fasting will just not be absorbed.

Are you fit? as in, do you lift weights or are active in sports that require strength? I ask because I wonder about the effects of extended fasts on muscle loss/retention, a big problem cutting weight for some people is that they get rid of some muscle mass along with the calories they wanted to eliminate.

Around my 30s I was quite overweight ~310lbs/140kg. Had done some stronglifts 5x5 and then decide to incorporate Keto into the mix (later targeted keto + IF). In the course of few years went down to ~230lbs/105kg while my lifts all went up (e.q squats from around 375lbs/170kg --> 460/210kg). At least my personal "gut feeling" is that I gained some muscle mass (my priority was to drop weight/fat).

For the past year, as an experiment, I've eaten carbs "normally" while doing 4x week gym. Few things I've noticed. My gut doesn't feel as good as it did while keto/IF, when you are in Keto and eat a cup of oatmeal ~45min before gym and start lifting you have this insane focus for the heavy 1-3 reps, I can seem to tolerate more better quality volume now compared to while doing keto/IF. But the overall feeling I have outside of the gym while not being in Keto/IF is a bit "sad", so most likely I'll start doing Keto/IF again to feel better. It's funny how insanely sweet strawberries taste while in Keto, and I kinda miss that feeling.

"According to the finding of the research, any amount of Pb, Hg and Sn were not detected in the organic certified nuts. In the organic certified nuts, the levels ranged between 5.53-123.78 ppb Cd, 8.22-16.62 ppm Cu, 0.24-1.86 ppm Ni, 15.03-46.37 ppm Zn, 444.1-810.6 ppb Cr, 22.06-67.42 ppm Fe and 1.24-3.14 ppb As."[1] Perhaps you are speaking of conventional (non organic) nuts and seeds ? I would not consider consumin…

Why would organic nuts have less heavy metal toxicity than conventional? Your link is broken btw.

Based on the quote I tracked it down to this paper: "Determination of heavy metal contents in some organic certified dried nuts". I can only access the abstract, couldn't find it on sci-hub. The study is focused on organic nuts though, it's not specifically an organic vs non-organic.

I was heading to the gym near the Twitter HQ in SF yesterday and saw Jack Dorsey walk past. He looked extremely thin and borderline sick to me. I think he does more extended fasts over the weekend but it’s a bit unnerving when someone in a position to influence behavior like he is seems to be taking fasting to an extreme.

At the same time many magazines glorify obese people (women generally) saying they are beautiful.
