A lot of diets, especially IF style diets, are pretty much just tricks to get you to eat less calorie wise. Intermittent fasting does this by just setting the simple rule, only eat during a relatively small window of time. It's easier to eat less during that period because there's only so much you can comfortably eat in that time. (Granted you can totally fit a whole day's intake in the IF period but it's harder).

> It's easier to eat less during that period because there's only so much you can comfortably eat in that time. Unless you're a food addict, in which case you can trust me that neither time limitations nor discomfort is an obstacle to filling your gob.

True on the face of it but if someone is able to do IF at all they have at least some control over their urges to eat.

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.

I'm personally very skeptical [as well]. I notice that almost nobody that recounts their fasting experience ever mentions sport. I personally found very hard already to progress on weightlifting during diet cycles, as I need to cut on volume significantly; can't imagine to do that while fasting, unless fasting would "flip a switch" in how the (my) body works, which I doubt.

There is some evidence that appears to support the idea that there is a difference between calorie restriction and complete fasting. You sound like the type of person that likes to dig into the studies. Dr. Jason Fung does a good job of writing in plain English while linked to and referring to the supporting studies: https://www.dietdoctor.com/fasting-muscle-mass

The studies may not have been conducted among athletes so, testing your own body's response (by measuring lean body mass before and after a fast) seems like the best way forward.

I have read that people on keto diets or fasting have less "explosive" energy for workouts. I am not concerned that my body is going to cannibalise my biceps if I don't eat for a day or two. There is a lot more energy kicking around that is less important.

For me, it's worth it for the HGH boost: https://www.dietdoctor.com/fasting-and-growth-hormone

I'm just saying, if your rule is going to be "eat whatever you want during your window", that's never going to work for a food addict. Ultimately you will have to count calories regardless.

- 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…

In a talk my parents sent me a few years ago, the speaker (I believe a nurse) argued that you need at least ~20 calories to trigger a metabolic response. Hence, things like tea, coffee (even with a tiny bit of milk), fish oil, etc. should be fine.

A tablespoon of cod liver oil has 122 calories.

I did for a few months this year, but I've been lazy over the summer. I'm 155lb, 6'0, so fairly skinny, maybe at around ~15% BF. I noticed that fasting doesn't help with BF at all unless I eat very clean and lift. I was at 170lb, around ~28% BF earlier this year and had to work my ass off to get my body fat percentage down.

Lifting specifically, or any sort of physical activity? I’ve been running and IF for the past month in order to cut my BF %. I was at about 16%, but I’d like to get down to 12%.

I've found that lifting is much better for weight loss than running/biking. I've gained weight while running 30-40 miles/week and typically lose weight while lifting (if I pay attention to my calories.) A lot of people say the same.

If you're focused on BF%, lifting is even more appealing since you'll be building muscle/reducing bf% even at a constant weight.

Be careful If you are going to try fasting. If you read carefully, fasting increases PUFAs on the serum and if you have plenty of PUFAs in your body, it could kill your thyroid and metabolism.

Before trying fasting be sure to have at least a month of healthy eating and try sipping unsweetened lemon juice while you fast.

>shifting about 20-30% of my calorie input to nuts I wouldn't do that. Nuts contain tons of metals that you don't want to overdose on.

"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.

The comment I responded to did not add substantively to the discussion, and I pointed out why. I am not "policing" anything. I have no power to arrest someone or censor someone for being an asshole online. I expressed an opinion about the kind of community I'd like to be a part of. Also, it seems like you're doing what you're criticizing me for. I don't think the world's got enough of minding one's own damned busines…

> Also, it seems like you're doing what you're criticizing me for. Sure, but only in a meta-sense to curb the proliferation of the technique. I'd liken it to nuking would-be nuclear powers to prevent further problems. And maybe, _just maybe_, Jack Dorsey should eat a sandwich.

> I'd liken it to nuking would-be nuclear powers to prevent further problems.

So, when you wrote this, did the idea of using nuclear weapons preemptively seem like an obviously good idea, to you?

Been doing intermittent fasting for a long time now and have been doing ADF for the last few months. I lost fat and retained lean muscle while - eating between 3000-6000 calories on eating days - running 30-35 miles per week - weight lifting 3x per week Here is a reddit post about my progress with some documentation including pics of recent DEXA scans. https://www.reddit.com/r/leangains/comments/cliuqk/been_prac...

Regarding exercise during IF, does it have a negative effect on your performance if you don't eat some carbs BEFORE exercise? How do you prevent the body from eating itself up for energy during exercise?

true, but food addicts usually have other issues with self-discipline as well, and IF makes it easier to stick to the program as you have to count your calories only once a day... at least it's my experience
