Black Cat Systems has announced that Diet Sleuth 4.8 (US$34.99) has been released, the latest version of its nutritional database and personal health logbook. A built-in Recipe Editor allows you to quickly enter a custom recipe, with the nutritional information automatically calculated, based on the ingredients. Diet Sleuth can also keep track of your daily weight, and calculate your EER or Estimated Energy Requirements, which is an estimate of how many calories you burn each day, based on various factors. This version adds the printout of a daily summary of foods eaten along with a pie chart showing carbs, fat, and protein, some general improvements to the user interface, as well as several bug fixes.
