Hi Gillykins
I’m on day 14 and loving the approach – I wish I had come across this months ago!
I use weightlossresources to plan my food intake but I believe myfitnesspal works well and is free.
I would definitely encourage you to weigh your food. It sounds a pain but once you get into it, it will become second nature. It will also help you plan meal sizes and where and when to use your calories. It helps me SO much and I’m sure it is key to my success along with re-reading the book on my Kindle. The more you weigh food the more you’ll start to recognise portion size. This will help when you are in social settings where you definitely won’t want to be weighing food.
Chicken breast sizes are so variable so you would need to know the size and calories.
When I started I did spend a lot of time working out calories for the food I wanted to eat. I now have a list of food I love along with their calories. One thing I have discovered is that I have had no problem in sticking to 50g of carbs as I’ve now realised how bland carbs are compared to avocado, nuts and seeds on my salad (all weighed!), oily fish and meat.
I never thought I would be able to stick to 800 calories, I thought I’d feel like I’m missing out but I LOVE this approach.
