I wanted to get into MFP because I love stats and stuff, but I never could work it out. It would have default portion sizes and I couldn't enter my own, so it wasn't as accurate as I'd want it to be and I wasn't going to increase my portions to fit the default portion sizes in the app. for example, I eat 30grams of cheerios with 90ml of semi skimmed milk but MFP has 40g of cheerios with 120ml of milk as the smallest portion size you can choose (Or something like that) there are similar issues with other foods I tried to put in. I just use the nutritional information on the food packaging, or google with fresh produce and a digital kitchen scale, with a calculator. It's a lot more accurate and takes about the same amount of time as the app. The only problem is that I would like to make use of the apps tracking features and food history. I just wish i could put my own custom values into it. Maybe I'm missing something.
