1500 calories is far too few for you & I suspect 1890 is, too. I’m 5’5” & am currently losing 1/2lb per week based on 1820 & fueling my workouts. Last year, I was just riding a few times per week & eating 1500/day & lost weight very well but I’m a little guy.
There are various BMR calculators on the internet. Find a couple & put your numbers into them to see what comes out. At my age, height & weight I’m just shy of 1500.
Somebody up there ^^ mentioned Matt Fitzgerald. I’ve used his Racing Weight QuickStart guide in the past & it really helped me to drop weight relatively quickly & then transition into a more sustainable low loss/maintenance pattern.
You can get to where you want to be, just take your time & figure out what works for you.
