@prodigalson8523 Best of luck!!! You got this, just don't obsess over counting and don't do a drastic deficit, okay? - been there, done that - it wasn't nice and at some point I was crying every day. Remind yourself that even a 150 calorie deficit a day is a deficit and that losing slowly is better and more sustainable in the long run. No need to go 500-600 lower a day, you can and should find a deficit that helps you lose while staying energetic and feeling yourself.
Just out of curiosity, if the average height there is about 150-155, how much do you reckon ladies weigh? I know Japan can be notorious for beauty standards and such, that being slim is seen as a virtue and all that jazz, so just curious if we're talking 40-45 kgs lol, or in the range of 45-55 in your perception.
As a small person (153cm, 47-48 kg) but with a pretty squared body (played tennis for a long time, so no hour-glass figure I'm afraid, more like looking fit and athletic, but no boobs at all and not necessarily conventionally feminine), I always feel way bigger in my home country where women tend to be petite and gorgeous haha. I used to live in the Netherlands - man, I tell you I'd never felt slimmer in my life!! So, don't let that bother you too much.
