The first time I even heard about caloric restriction I thought it was out there. I did eventually try intermittent fasting and after skipping breakfast and lunch I was rewarded with a pounding headache from the lack of my daily morning muffin and coffee.

I literally had to go home from work to recover. I didn't try again until I saw this programme here in the UK: https://www.bbc.co.uk/programmes/b01lxyzc

Like a lot of difficult things it takes time and practise. I got better at doing it, but it's still really difficult, especially if the rest of your household don't practise it and you're seeing everyone else around you enjoying their usual meals and food treats.
