I've had similar results with blood pressure, although a smaller weight loss (about 30 lbs) and smaller decrease. Another 10-20 pounds to go.
For what it's worth, I'm on a intermittent fast. I only eat between 5pm to 10pm, with no real restrictions on what I eat. I was surprised how quickly weight fell away, and how easy a diet it was to stick to. 'Eat after work' was a simple behavior to adapt to.
People are very individual, and this might not work for a lot of people, but it's doing great for me. I didn't want to spend the rest of my life on blood-pressure drugs.
Isn't that an extreme version of IF?
I think the usual window is 8 hours, so people should first try eating between lunch and dinner, say 12PM-8PM.
A lot of people eat breakfast out of habit, and I found that once I got older, I just stopped needing it. It made me bloated and sluggish. You just don't need that many calories per day when you stop growing or not working in construction.
