Usually on diets where you go from a carb heavy regimen to less carbs:
first you lose water weight as electrolytes start to balance due to the change in insulin levels
the body removes fat from organs as first priority (sometimes called visceral fat). The body does not want to store fat in organs, but it does so only if it can't put fat anywhere else. Once you start to lose weight it comes from here first.
then we are at generalized weight loss, which is different for everyone.
Thats a myth, here are some videos by a guy with a PhD, any sort of calorie deficit will result in fat being burned, unless you manage to break the laws of physics and create energy from nothing.
Eating enough carbohydrates to cover your energy need isn't a deficit. I meant what I said, the body uses what it has available but prefers "easy" sources
They were talking about going from carb heavy, to carb light, which is how most people cut calories. They aren't going "man I really ate too much steak yesterday!" They're thinking about that candy bar or that donut they had. Carbs are burned by your body first as you eat them because they're the easiest for your body to process.
They simply outlined the stages of what that type of dietary change usually looks like. Most useful information? Maybe not, but they aren't contributing nothing.
Any fat loss should come from your organs first. The only reason fat is stored in your organs is because your body is unable to store it any other place.
You're a very negative person, it's very difficult to have a conversation with you. You ask implicit questions, and then get angry when people answer the question to the best of their ability but wasn't what you intended.
Keto has no bearing on the loss on visceral other than it helps people lose fat. In any circumstance where your body has an opportunity to reduce fat, it comes out of the organs first. Because fat in the organs is extremely unhealthy.
