I would look into MyFitnessPal and do a calorie deficit or basically well eat less move more approach always works 

But about your question, DHT isn't something you want to play with, it can seriously attack your hairline it is the leading cause of male pattern baldness so if you continue down this path be very careful as DHT reacts to people differently.

I've taken a LOT of Pygeum which would reduce DHT, so I think getting it up back to more "average" levels might be beneficial?
Dieting and gym workouts haven't made a dent on weight loss, there's likely a hormone imbalance that's causing an issue.
I know I have low T, I could get more blood tests to check. Thyroid seemed fine last time I got a test, and am now on TRT as well.

there are a couple of other things you can do to try to lose weight without messing with your DHT. 

try eating hot peppers, hot as you can stand. the capsaicin in the hot peppers temporarily boosts metabolism. (you gotta break a sweat). this i know from experience. i lost 30 lbs in 3 months on a bet. just by adding hot peppers to everything i ate.

I have heard Apple cider vinigar is good for weight loss , but you need to dilute it in water, DO NOt drink it straight up. (2 tsp to 8 or 16 oz glass) . i am currently using to reset stomach acids and lose some additional lbs.

Also i had a boss who swore by eating a half a grapefruit before he went to bed. (not sure if that works).  He claimed that it help him lose weight. 

hope some of this helps...
