Yes, there is certainly something in it - My type 2 went into remission when I started to just eat one meal a day. I wake up at 9.30 to my alarm, & not have breakfast, (never have) then go for a walk (my exercise) skip lunch, then have a cooked meal with all the trimmings around 5pm
Little snooze until about half 6 / 7 then I wouldn't be hungry at all (as I was still digesting my meal) before I fall asleep around 1am
Next day, repeat. Made a huge difference to my readings - I'm still on metformin (because my one meal a day isn't always exactly healthy) but a HUGE improvement from when I was eating several small 'Healthy Meals' throughout the day - Sounds almost counter intuitive, but it DOES work
