Yeah I went to one meal a day (lunch) about 6 months ago, this is only for during the week... weekends is a free for all, I love my BBQ and beer.
For my weekday meals I pre-cook and freeze (Pasta/casserole/stroganoff etc etc) in 400gm portions, At first I used to devour that 400gm portion, now I struggle to eat it all.
I did it for weight loss and to date am down to 83kg from 124kg... goal is 65kg.
I don't do any exercise but am on my feet at work 13hrs a day 5 days a week.
