I started Atkins' induction a little more than 2 months ago, and after the first 2 weeks on 20g of carbs, I didn't lose that much weight at all, and fell into the category of metabolic resistance. A couple weeks later I discovered intermittent fasting (IF), and found that in once sense, we all do it. All it is is the break between meals, especially the time from your last meal (dinner) to when you sleep and wake for your first meal (breakfast).
When you do IF, you create a break between meals and your insulin levels have a chance to drop, compared to eating 3 meals a day and snacking between them.
So IF can be many things - one I like is 16:8 (sometimes seen as 16/8) - you eat during the 8 hour window, then you fast 16 hours from your last meal until your next meal. Say you eat breakfast a 6am, lunch at 2pm (8 hour eating window - no snacking between (or after)), then you skip dinner and by 6am breakfast the next morning you just fasted 16 hours.
Another IF is OMAD (one meal a day). Eat one meal, and fast until your next. Depending on when that next meal is, you could fast for 24hours.
One thing I quickly found is that hunger was not an issue when I did IF. Your body keeps it's basal metabolic rate and if you were in ketosis from low carb, you keep burning fat, and you'll lose weight (and inches). I lost weight, and inches from my waist.
The beauty of it is you do IF when ever and however you like. If you start a 16:8 and decide you're going to have dinner anyway, no problem - continue it the next day - no big deal.
edit: most of what I've learned of IF has been through Dr. Jason Fung's books (The Complete Guide to Fasting, The Obesity Code, and The Diabetes Code) and his videos and IDM blog postings. Here is a good video to start. It's Megan Ramos, who works with Dr. Fung:
