How many calories/day for optimal feminization?

I'm 5'9, 29, a little over 2 and a half years on HRT. I've gained 20lbs since starting HRT from 155-175 (10lbs in the first few months and 10lbs at about 2 years) , but wondering if that's why I've seen no results. My BMI is listed as "overweight", but I'm not seeing proper results from HRT.
