I just turned 50. I'm 182lb at 5'1. I'm trying to lose at least 50-80lbs through IF and EF. I fasted 400 out of 480 hours Dec 12-31, and 110 hours so far in Jan. I've only lost 8lbs. I keep my eating window short and eat only whole foods, low carb. in small portions. When I was younger, I could do this and lose 20lbs in that time. It's VERY frustrating.
It's crazy isn't it?! Absolutely diabolical
. It's bad also because one gets into all sort of negative ways of thinking, from 'my body is against me', to 'fuck it', to 'it's not fair', etc. It takes absolute ages to lose a few pounds and literally a day or two to gain everything back 
What about exercise? I have found that weight lifting, which increases muscle mass, seems to have a positive effect on metabolism and mood and general feelings towards my body. No gym for me, I have a set of dumbells and a mat at home.
Walking is no good... I enjoy walking to work and back, around 45 minutes each way, but it makes me so hungry! I invariably end up bingening in the evening.
As I have BED I just try to eat normally, 1,700-2,200 calories a day, restriction triggers my binges. Been experimenting with intermittent fasting, but I need to be careful with it for the same reasons, also if I'm in hot flashes phase drops in blood sugar levels send them crazy, even at nightime 
By the way, I see from your stats that you have gone from 240 to 182, congratulations, it's a great result, well done
