> you thought that cells only metabolize glucose, and dietary fats & proteins are converted to glucose Pretty much. I don't know where that may have come from, but I suspect I'm not the only one who naively thinks that this is the case. Somehow "ketone bodies" aren't mentioned in dietary conversations nearly as frequently as glucose.

LOL yeah, I just spoke to a dietician the other day who swore that glucose is the only thing your brain can use for fuel. It's easy to be ignorant about a situation you never experience. Every single person they deal with is going to be in a carb-adapted state and never miss a meal, so their body will run entirely off of glucose.

I vaguely remember reading about this in "The Ketogenic Diet". There are some functions that do require glucose. However, your body can convert enough fat and protein into glucose to satisfy that.

As a long-term ketogenic eater (10 years), here are my top simple tips. Unfortunately they were not gleaned using machine learning. 1. Watch your protein. Most people when first going keto will eat too much protein and not enough fat. Protein has an insulinogenic effect when eaten in quantity. Keep protein below 8 oz per meal. Don't be afraid to eat more fat. 2. Avoid cheese. Yes, it's technically low carb, but it re…

Cheese is the only way I can stay on Keto. Nuts are good but in small amounts. It's way too easy to over eat nuts in calories and carbs. Especially since the better they taste, to me, the more sugar they have. I'm looking at you cashews.

I don't think it matters whether you run 4 passes or 1 pass, it's still going to overfit. You can run an online linear regression in a single pass too, but that doesn't magick away the uncertainties. The results are still going to be garbage, and any effects you get are due to your health-consciousness and not any specific dietary choices you make (how could it be, when the data is so weak and noisy that each item ca…

Thanks so much. Your comments are really helpful. I realized early on that the data is hopelessly noisy, due to the small daily changes and the scales resolution so rather than trying to build a perfect model to gauge the variable importance of each and every kind of food, I focused on the few days when weight change was more significant hoping I could detect some signal in those, and extrapolate and further explore…

Is it possible weight loss made you sleepy?

Ketosis is the greatest thing to ever happen to me. It has been life-changing for myself and many of my closest friends. I lost over 200lbs doing keto and it was one of the easiest, most ennjoyable things I have ever done in my life.

Keto is absolutely amazing and life-changing. I encourage everyone to try it.

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…

What you are experiencing is called the placebo effect. Google it.

Yeah, that was a TIL moment for me when I found out the body can make glucose without carbohydrate. There were others, like how mitochondria burn fat more efficiently than glucose.

I experienced this. I never needed to lose weight, always been lean. But I wanted to see if I could reduce my blood sugar since it was borderline high. So I went very low carb for a while. Did not intend to but lost 5 kilos right away and felt fine, although it seemed like I was a bit underweight. A few weeks later got a miserable case of flu and couldn't eat for a few days. Lost even more weight, felt terrible, look…

My research indicates those 5 kilos were probably mostly water because when you go low carb your body uses up all of its glycogen, which is stored with 3-parts water, and that takes a lot of salt with it. So you have to drink more often and consume more salt. Then it can take 2-4 weeks for your body to ramp up the right chemicals to switch to fat burning.

Ingesting more salt goes against common knowledge (which doesn't mean it's wrong).

Usually people state that the salt keeps the water in the body, so if you want to lose weight you need to lower your salt intake.

But what you say kinda makes sense, I'm interested in hearing more of your ideas.

One thing I've never been able to get a clear answer on, is when you "lose" fat, how long does it take for the number of fat cells to go down? As I understand it, at first fat cells just deflate (not the right word) are will easily plump up again and that's one reason why it's hard to keep weight off. What's involved in actually ridding the body of the extra cells (outside of mechanical means)?

Any dietician will tell you that fat cells never go away.
