Are you saying there's 120 calories in 100g of pasta?
Sorry - checked again it is actually 150 calories per 100g . But still my point is that it is a relatively low calorie food and should not be on the excluded list with fat and sugar.
100g is about the amount in a lasagne, a normal portion would be more.
Basically if anyone wants to work out how much pasta or rice or bread or potatoes they would eat over a day and then work out the calories in that food, they would most certainly be well under the calorie intake target on any weight loss diet.
Carbs tend to fill you up and if you are full you forget about food, so it is not an obsession. You just think about food at a meal time which comes along three times a day, at the point you start feeling hungry. The body is not pumping out "find food" messages all day.
If you cut out carbs and snack you are constantly running on empty and thinking about the next snack. A bit like driving around in your car and only filling it with one gallon of petrol, the fuel light will always be on. Also without carbs you end up with an over-rich diet as it is not bulked out.
