Hi and welcome to the forum,
I'm sorry things have been tough for you, you've had a pretty bad run. It's nice to see that you're still staying positive though, and congratulations on losing 1 inch off your measurements! Sometimes the scales can be cruel to us and not move, but if you've been working out and eating well, you can probably guarantee that your measurements are still decreasing.
In relation to what you should be eating for your diet, I think Brendan gave you some fairly decent advice. I also don't really count calories or follow any particular plan - it's mainly just about eating well and avoiding unncessary junk. As a very basic rule try and eat:
- As many vegetables as you like. (No, McDonalds fries don't count as a vegetable - I wish!
- 1-2 pieces of fruit a day
- 2 serves of dairy a day
- 2 serves of protein a day - lean beef, chicken, fish etc
- 2 serves of carbs a day - e.g. 2 pieces of bread, 1 serve of rice and 1 piece of bread etc.
The above guide may not suit everyone, but i've found that it's helped me a lot when I've been focused on losing weight. Basically, just try to focus on making the best food choices you can. E.g instead of snacking on potato chips, try low fat crackers and dip instead.
All the best
