Black Cat Systems today announced that Diet Sleuth 4.6 (US$34.99) has been released, the latest version of its nutritional database and personal health logbook. This version adds a quick “Find Food” button, improvements to the user interface, as well as several bug fixes. You can select from over 5000 different foods from 21 categories, including fruits, vegetables, breads, fast food, lunch meats, junk food, seafood, and baby food. 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 lets you estimate how much weight you can expect to lose on a given day, based on your caloric intake.
