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

Glycemic Index (GI) is a ranking system for foods containing carbohydrated. The GI number signifies how quickly a food triggers a rise in blood glucose (sugar).

High GI food tends to increase hunger and promote overeating, which can then lead to excess weight gain and obesity.
High-fiber foods, which generally have a low GI, move slowly through the body. Because they stay in the stomach for a relatively long period of time, they promote a feeling of fullness.
