No one knows that, cup isn’t a proper measurement unit, maybe for cooking in some cases but not even then… Use a kitchen scale and grams. That’s it. Much work if you have 32 items per day (probably not, it was me on low-carb and keto…) but there are guesstimation shortcuts if it’s very needed… I barely did any, I just measured 18 times for a soup sometimes… BUT it didn’t make my fat-loss more sure…
I can’t imagine how anyone can raise their calories only by 100, I raise it by 1000 without trying, it’s not even necessarily wrong but one week? It’s normal to gain 2 pounds if you raise your kcals significally. Even if you didn’t. It’s a mere week, it’s NOTHING! I gained 2-3 kg in the last several weeks according to my scale (the one that decided I weigh the same warmly dressed and naked so it’s more like 2kg) and my pants didn’t get any tighter, rather the contrary (and I never had this but well, there is a first time for everything except what never happens).
One week is nothing. You can’t figure out much in one week fat-loss wise. It’s WAY too little for that. And it’s about eating a healthy amount of food now, fixing your metabolism, not necessarily fat-loss but the previous things are pretty much needed for the latter if you want to do it healthily anyway (not like it happened with your truly super low-cal diet. and we say it’s very low as it’s very low for your stats. we are different, sure but when I was 170-180 lbs and inactive, I easily lost fat eating 2000 kcal. that is a tiny bit lucky but still normal enough. 1200 kcal is low, one may or may not pull it off with your stats but I would expect a pretty quick fat-loss or would think about slowed metabolism. and doctors often say stupid things, we know that).
Forget percentages (or not, they are fun, I like numbers but don’t try to fit into some more or less random numbers…). Eat low enough carbs, enough fat, enough nutritious food. Whatever it means for you, we are different regarding that.
I wouldn’t even feel okay with 10/20/7%. I couldn’t ever do 10% and stay in ketosis, to begin with… It’s probably true for most of us. But the protein is very off for me too, it never would work. The fat/protein ratio is okay for money but it’s too much carbs or too little food for most people. IF you experience it works for you, do it that way but it doesn’t seem so. And rigid percentages are usually a warning sign to me.
