I must be so gullible. Before I started this diet, if a recipe said 200 grams of something and I opened a 400 gram tin I would just split it in half and assume I had 200 grams. Wrong, just opened a 400 gram tin of chickpeas, actually weighed 200 grams and that left just over 100 grams. I assumed net weight meant without the weight of the tin, but no, it is the weight of the total contents so when you pour away the water you have lost about 100 grams. Another example, tinned tuna, net weight 112 grams, pour away the water and you are left with 90 grams of actual tuna. This can be important when counting calories, so just be aware and weigh things after removing from the tin.
