I remember seeing pizzas in those apps listed as 200 calories. It must be a combination of inability to understand portion sizes are not the entire thing and malicious editing. Hams must think that, if they can make the app say a pizza only has 200 calories, then it does. The app contains technology that directly communicates with and modifies your metabolism remotely. I stopped bothering with them years ago. By the time you include the inaccuracies of the manufacturer's calorie counts, the inaccuracies of people reporting those counts, and the variability of the actual calorie counts for a specific versus generic item, you have three levels of fudged numbers. If an apple could have 50 calories or 120 and that's just 1 single apple, you might as well guess or just work by whether or not you're gaining weight. I also found that having a diet that it mostly the same thing over and over again means you're just putting the same numbers in over and over again and I stopped seeing what I was getting from the app. Having a general understanding of food and calorie counts, knowing what is likely to be rich, being honest about when you're overeating, and knowing what normal portions look like is all you really need. The exact numbers aren't so important. Weight control is easy and I think the main audience those apps serve is fat people who deliberately misreport their intake and then fraudulently present their misreported intake as proof that eating less doesn't cause weight loss. If it's written down, it must be true!
