I don't do 'denial' and would rather do without than plan my week around low fat, low cal,low sugar, low taste foods. So what works well for me is a bowl of special k and skimmed milk(long life because it;s creamier) for breakfast - fresh fruit, tea, coffee with sweeteners or low cal drinks through the day 'as and when' and then for my evening meal I have whatever I fancy with a diet drink to fill me up before I eat so that I'm half full already and don't pig out. (should add that i don't really like water).
This way I can look forward to my meal each day, I'm not doing without or "not allowed" anything at all. And I'm no different to anyone else in the family. It's surprising how quickly not eating lunch becomes a habit and the pounds drop off effortlessly.
