There is also the question of the quality of the carbs you eat. You should get these 20 carbs from salad items and veggies - not from sugar or starch - and they should be spread out through the day.

Apart from that you should eat unprocessed meat, poultry, eggs and fish (in all cases with the fat left on).

You eat until you are satisfiied - not stuffed and drink at least 2 litres of water a day.

On this the majority of people will lose weight.
