Black Cat Systems has announced that Diet Sleuth 4.9.0 (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 options to duplicate a food in the food editor and print out food and recipe nutritional information, as well as enhancements to the user interface and several bug fixes.
