What's interesting about this post isn't the actual diet advice, but the guidance to track and see what works for you. Different people react to fasting differently - some continue to burn calories and drop weight, some just go into starvation mode, have their BMR crash through the floor, and end up exhausted all the time because their body is fighting like crazy to conserve energy. Likewise - some people, when they…

>Everybody is somewhat different in how they'll react to various diet and exercise regimes. Understanding that, and taking a bit of time to watch how your body responds, is the important insight here.

This exactly. I did the same thing to lose a bit of extra weight, except the machine learning part was just using my noodle. I found it interesting that the author didn't notice sleep reducing weight right away. He only measures morning weight. If he measured morning and at night before bed, he would have noticed right away. Some other things the author seems to have overlooked in his analysis.

1) While sleep is good for weight loss, eating before sleep is not. I give at least a 2 hour window before bed where no food is allowed.

2) Track how often you poop. When I'm not pooping, I'm putting on weight. I don't mean poop is heavy. The stuff floats. Weigh before and after a big poop and be prepared to be surprised. People will commonly say that weight loss is just energy in 3) Weigh before bed too. I noticed some foods were "soft" weight and some are "hard" weight. Soft weight goes on fast but drops quickly. I found some things shoot my night weight way up, but it's mostly gone by the next morning. Other foods, hard weight, put on fewer pounds, but take days to lose again. For me, fried potatoes are the absolute worst hard weight. Anyway, if you only weigh in the morning, you may see you gained a pound from the day before. If it's soft weight, no worries. That will be gone before lunch. If it's hard weight, it will still be there tomorrow, and the next day too.

4) Be on the lookout for magic combos. Some foods individually are weight gain, but combined are weight loss. Take coconut rice as an example. Rice by itself is a soft weight gain for me. It's not hard to lose, but it puts on pounds. Coconut rice on the other hand is weight loss for me. My spouse made it with some spicy thai chicken and I fully expected to gain, but I didn't. Now I can eat it without reservations. Apparently, I'm not alone, and there's some science behind this one

The author is wrong that sleeping more just gives less time for eating. Truth is that sleeping more reduces insulin resistance, increases testosterone production in males and puts leptin under control. All three reduce carb craving, push us towards meat and fat and increase natural fat burning.

Thank you. Getting plenty of sleep also lowers levels of "stress hormones" like cortisol, which tend to promote fat storage.

Which is sort of what those hormones are for. It's easy to see how ancient humans or proto-humans who had this tendency to store extra calories during times of stress, would've had survival/evolutionary advantages.

Therefore don't mimic times of high stress by shorting yourself on sleep!

> It's pretty easy to lose 40-50 pounds and end up being much less healthier than you were before Maybe if you amputate your legs or catch AIDS or syphilis in the process. Otherwise, I can't see how losing 50 pounds will leave you less healthier than before.

What I was trying to say, perhaps poorly, that is if you were heavy because you were working out a lot, and eating a lot, and then decided to lose weight by reducing the eating/working out, you can end up being skinny/fat/weak. At the very least, doing regular body-weight resistance training (pushups, situps, pullups, air-squats), helps to reduce the amount of muscle you are losing while you are losing weight.

And you can lose weight but look bigger if your muscle to fat ratio goes down. Fat is less dense, it takes up more volume per equal masses of muscle or fat. It should never be about weight loss, but muscle to fat ratio, as I wrote about in the thread above. You will be healthier when you lower your fat percentage and boost your muscle mass. Weight does not differentiate between between fat or muscle.

Might be lacking glucose; I believe that is why marathon runners eat glucose before they run.

Some corrections from the point of view of an endurance athlete (triathlon). First of all you don't really "eat glucose", that would be an oversimplification. Glucose is produced by your own body when metabolizing carbohydrates. As a backup mechanism your liver can also produce glucose by converting amino acids (muscle) and even fat, a process known as gluconeogenesis. Now, if we replace "eat glucose" with "eat carbo…

All of this with the qualifier 'marathon runner' or 'endurance athlete', since explosive, short-duration, powerful sports require immediate energy reserves, which they readily deplete when you do this type of exercise. Fat metabolism would be too slow for the quick, short types of activities.

I also believe endurance or extreme endurance activities are more for your enjoyment than fitness. They take their toll on the body's joints, organs and regulatory systems. Moderation is good advice in lots of things.

I don't have a weight problem, I learned about ketosis researching natural ways for improving focus and concentration, and somehow came across "bulletproof coffee". (I'm only using BP for lack of a better name and I don't endorse the stuff they sell online). To my utter surprise, something as stupidly simple as coffee blended with butter with coconut oil (or MCT) first thing in the morning did unbelievable things for…

"Bulletproof Coffee"(TM) is snake oil stuff. It's based on the assumption that all other coffee on the market has mycotoxins, yet literally none of the brands in first world countries have them anyway. This was confirmed by tests.

He started off by selling high-fat coffee creamer and sugar-free hot chocolate, which are reasonable. It's only later he's gone on to try to convince everyone coffee and wine are full of secret mold toxins.

Magic beans ? This sounds familiar.

Earlier quoted context omitted.

I do a lot of rock climbing, so most of my body is muscle. I'm currently floating at 170 lbs, but would love to lose 10 lbs so I can get up the wall faster. I think that fasting might be foolish because my body needs energy for climbing. In fact, if I wait too long after eating lunch, I tend to get really hungry during climbing and I start yawning a lot (not sure why).

Just fast on rest days, or don't climb those days. Go for a a short/easy hike or something. I do a lot of cardio. Some days I will burn 5000+ cal. I am absolutely unable to lose weight or restrict calories on those days because I always feel insatiable hunger.

Interesting - I can do 3000-4000 calories through cycling and get away with only a small protein rich meal (scrambled eggs + steak) after. Even today, another 2 hour mild session (appx 1000 cal) and have only had light breakfast, coffee + pie. Hunger is there, but not at the forefront at all.... unless I eat a few sugary meals in a row.

I'd really like to see this kind of analysis applied to a larger sample. If someone were to put together a little app to make this sort of data collection trivial and upload it to a central (preferably cheap) repository, would people be interested in contributing their data in exchange for analysis? Also, since this is HN, is anyone interested in building something like this? I've got an hour or two a week of spare t…

We are working with a few groups to make this sort of this possible. Feel free to reach out if you are interested.

I'm interested!

Warning: unpopular opinion here. Long term low carb dieting and ketosis is not without risk. Yes, you will see weight loss, but what about other health markers? Check out some of the information here: http://nutritionfacts.org/topics/low-carb-diets/ What has worked for me was a plant based diet without added oil and processed foods: https://medium.com/@borkdude/tl-dr-of-my-long-term-weight-lo... Been doing that for f…

For once I want someone who isn't morally opposed to eating animals tell me that low carb diets are bad. Vegans and animal lovers don't like low-carb-high-fat diets because it requires eating a lot of animals, so I find it hard to trust them.

OK, then watch this lecture by Denise Minger. She is known within paleo circles and is pretty unbiased when it comes to eating animal foods:

The observation that "no breakfast" is #1 way to lose weight by extending fasting period that includes sleep is pretty astonishing. Everything I have read says no breakfast is one of the contributors to weight gain.
