Mine weight scale has resolution of 0.1 and accuracy of about 0.2-0.3. It doesn't matter that much because if your input is noisy your output will be noisy but if you use it intelligently you don't have to eat -0.2kg ;). I've seen that typically I need to eat about 0.7-1.5kg daily and if some day I get result lower than 0.2kg I just eat 0.2kg, no less. It may mean that I eat very little for about two days and then it's back to normal amount. Your mileage may vary, but if you use this diet you WILL lose weight. After going to target weight my calculator maintains constant weight reference so that I can control my weight and don't have yoyo effect. Measuring food - I just weigh myself after morning piss and calculate amount of food to eat that day. 1/4 for breakfast, 1/4 for lunch and leave 1/2 for dinner, but before dinner I make last measurement and eat accordingly. Before that diet I've only eaten 2 toasts for breakfast, but now I'm feeling fuller through day. For food weighing I have small pocket scale which can measure up to 0.5kg (res 0.1g) but I could use a scale which has a resolution of 0.01kg. I don't measure drinks, this is a small source of noise but not really important. After several days of measuring various foods you have pretty good mental scale. I don't eat lunch with friends/coworkers, so premaking measured food portions was best case for me.
