I think your view is a little harsh. The concept and practice of ‘feasting and fasting’ is not inherently dangerous, indeed it’s promoted by many experts in fasting for health, including Dr Jason Fung - see this article. Many on here (including me) find intermittent fasting to be an excellent adjunct to a low carb/ketogenic way of eating.Goodness you are taking risks ! Splurging and then fasting? Are you joking ?
You should be eating steadily and carefully- I’m sure you know that. We all go off the rails a little bit but this sounds extreme and very dangerous. It isn’t your gadget you shouldn’t trust but your commitment.
And to get back on topic, so far I‘ve not eaten anything today. Am peckish but meeting a friend for lunch, so saving myself for that. Details and possibly pics later.
Consumption has been limited to a pint of iced water with fresh lime and pink salt and some Diet Coke! Hopefully lunch will cover me for the day, but if not there are some cold meats in the fridge.
