Half information and a gross oversimplification yet again. https://www.sciencedirect.com/topics/neuroscience/gluconeogenesis This is the process by which fats, proteins and in certain cases alcohol is converted into glucose. Since you won't read it, because you didn't read it the first time I'll tell you again that even if you eat zero, none, never any, carbohydrates you'll still create glucose by that process. If you eat an excess food energy be it in the form of alcohol, carbohydrates, fats or proteins you'll will gain weight. If your body burns 2500 kCal in a day, and you eat 3500 kCal of protein in a day you will store the excess energy that was not used for the Kreb's Cycle in the form of glucose, as adipose tissue. And again insulin is required to move that energy into the cells. If you're tolerant to insulin you will not uptake into the cell, to be converted during the CAC to ATP and your body will starve. Your muscle cells and others will whither and die. Type 1 diabetics tend to be very skinny if they do not take care of themselves as they do not uptake the glucose they need. Insulin does not shove anything into a fat cell that does not belong there. If you have less energy in your body you will store less fat or pull from fat for energy. You don't have to eat less carbs specifically, just eat less of everything. You can eat roll, drink beer, eat a steak and still lose weight so long as the overall kCal at the end of the day is less than the overall kCal that is required by your TDEE.
