Any of the advice above. The trick is finding what works for YOU!

For me, calorie counting does my head in. I much better watching portions and limiting carby foods. So for me, TWD or the 1 Million Kilo Challenge meal plans (which is based on Weight it Up), seems to work for me.
Planning helps, having idea for the day or the week. So knowing if I want rice with dinner, then no bread with lunch. Also means there is less chance to slip and grab the easy foods which are not good for me.
