I'm down 50 lbs but still look exactly the same

My clothes fit the same. My mirror reflection looks the same.nothing seems to have changed. It's frustrating that I've been doing this for just over 6 months and I still see no evidence of it. Just shows how much I have to lose. Sw 386 cw 336 gw 185. I've got a long way to go, but this is a start I guess. I need to start exercising more. I only do a mile a day on the treadmill, but know I need to expand what I'm doing. I recently changed from keto to cico. I'm eating in the neigh orhood of 1200 calories per day. Some days a little more. All in all, I'm proud of my weight loss, I just wish it showed more.

ETA - TIL about the paper towel effect and am encouraged to keep going to see the bigger changes. Thanks all.
