The simplest way is to eat as varied and as colourful as possible. The colours in the vegatables indicate the vitamins in them.It is my lifestyle now. I am on low carb, low fat, high fibre, high protein and a hour brisk walk 5 times a week, and I have lost 31lbs/14kg and gained better health. I am now maintaining my 108lbs/49kg for more than a year, with more fruits and complex carbs.Details such as my experience, meals, snacks, recipes, foods to buy, reading labels, walking as an exercise and to shape the body etc etc, are in my blog
