@LogocentricKorn Sorry, I must have missed something. This does not make sense to me:
What I mean is some doctors started if your waying 1 or 2 meals a day you need less macros less vitamins. Huge difference between maintaining my weight eating g 2500 calories and eating 1600 calories.
My first attempt to translate: "What I mean is some doctor(s) stated if you’re eating 1 or 2 meals a day you need less macros and less vitamins. Huge difference between maintaining my weight eating 2500 calories and eating 1600 calories.
If not, please advise. If so:
‘Macros’ are the ratios of fat/protein/carbs you eat, independent of how much you eat. For example, if you eat 200 grams of fat and 100 grams of protein, the macro ratio is 2:1. If you eat 100 grams of fat and 50 grams of protein, the macro ration is still 2:1. You’d eat half as much, but the macro remains the same.
Vitamins and minerals are not dependent upon how many calories you eat per day. They are based on how much of them you deplete/excrete and need to replenish each day. When you’re eating keto, these amounts may differ from what you needed before keto. Since keto does not retain water, many water soluble vitamins and minerals are depleted via urine and require replenishment more frequently.
Yes, there’s a huge difference between 2500 and 1600 calories. So the point is what? Do you know your RMR? Your typical DREE? You need to know those numbers, at least roughly, to determine whether or not you’re eating sufficient calories to maintain weight overall. Whether to eat more or fewer calories is also related to hormonal factors as well, since they affect how calories from specific sources are dealt with. Example: a calorie of fat gets metabolized very differently from a calorie of protein or a calorie of carbohydrate. Elevated insulin, for instance, will prevent fat from being used as energy.
