I’m trying to lose weight and was told that hwo I eat about 800-1000 calories a day is too low and lowers my metobolism which will prevent weight loss. I’ve looked up some meal plans and can’t really afford stuff like chicken breast, steak, or salmon every week. So that is why I’m wondering how I can eat 1500 calories a day. Are there some alternatives that I can do?
Also I’d like to ask, say I exercise and burn say 500 calories would I have to eat those calories back or no? I ask cuz I’ve been told yes and told no.
You cannot accurately measure just that. But measuring calories you eat is a good enough approximation to help you control how much you eat. You can estimate you calories out by your weight, if you are gaining weight you are eating (and adsorbing) more then you are using, if you are losing weight then you are eating less - and that is the most important part.
There is also water weight to account for, but realistically there is an upper and lower bound to that and over several weeks you can get a pretty good idea for what level of calories you ingest leads to weight gain or loss. And if that changes for any reason you can adjust the amount you eat in correspondence. We are just looking for averages over time and the overall balance here, no need to be super accurate with exactly what you adsorb and what you have accurately used during an exercise. I never even measure calories burnt as it does not give much value vs just weighting your self over time.
