Let's be real, this is the festive season and it's highly likely we're going to be eating big.
If dinner is going to be a big feast, opt for a small breakfast and lunch option or you could skip a meal all together. Enjoy your dinner and go right back to your regular eating the next day. Prepare some meals and keep them in the fridge or freezer. You can even eat left overs, as long as you prepare the right portion sizes for you to eat ahead of time.
