Honestly, I think to lose weight effectively, most of us have to accept that measuring and counting is part of it. The reason that so many people put on weight isn't that their food is terrible, it's because their portions are ridiculous. The meal you had was probably fine by itself, but needed smaller portions.
So regardless of what "diet" you choose ... you'd probably have the best luck if you accepted the necessary lifestyle change of measuring your portions first. Good luck with your journey either way.
