Last year I realised that I needed to sort myself out. I wan't desperately overweight, just unhappy with my body. I have always avoided 'diets' be they faddy or commercialised. I just decided to think 'natural'...
Breakfast - stick to wholegrain cereals, or a cooked protein based bacon & eggs etc. Avoid toast.
Mid morning snack - fruit
Lunch - salad with meat, cheese or fish and lots of carrot sticks celery, cucumber, radish, tomatoes etc
Afternoon snack - more fruit
Evening meal - home made food, nothing special just make it yourself, no pre-made sauces or microwave dinners.
Try to reduce sugar rather than fats. I don't go for the low-fat option, I go full fat (yogurt, coke etc...) but I just have it as a treat.
Don't go on a diet.
Don't calorie-count.
Don't weigh yourself (go by clothes size).
Do cut down on bread.
Do drink water
Do treat yourself (I eat chocolate, bread, cake, drink wine at weekends only)
Do be prepared! Make your lunch the night before. If you are out for the day take some healthy natural snacks with you (raw veg, fruits).
The strangest thing that motivated me into was getting a new bra... I know it's a bit weird but I had a proper fitting and the lady said to me "see how slimming it is now that you have a properly fitted bra" - and it was true! It really gave me a boost to start. I am now down from a size 14, to a size 12 - many of which sized clothes are loose (ish) on me!
Good luck - think natural!
