I did IF and ultra low carb (with weekly carb reloads) for four years starting in 2011. 16 hour intervals daily for IF.

My blood sugar, blood pressure and bodyweight got back to normal about midway and in the last two years or so I changed the routine to introduce daily carbs into my diet, but I only eat real food and not too much.
Last meal before 7:00pm, breakfast at 10:00am.

I also make sure I have solid 8 hours of sleep every night, longer on the weekends.

Additionally I changed jobs and stopped spending 10hrs a day at a desk.
All in all I dropped my pant size from a tight 42 to a loose 34 in the process... Been wearing the same size for the last 4 years - that has been always an indicator for me. Scales lie and mirrors are subjective.
My usual routine requires a lot of physical activity and I spend my days running around so that helps as well.

I think it's the combination of all of those things, but the so called intermittent fasting was a good start - it definitely did (and still does) play an important part in it.
