In preparation for their wedding, Simon Cowell’s fiancee Mezhgan Hussainy has reportedly put him on a strict diet, starting with a 5-week “detox” of vegetable smoothies and one protein meal a day. After an initial weight loss of 12 pounds, Ms. Hussainy is now helping Mr. Cowell count calories. We previously reported on a new iPhone application that could help them. PhotoCalorie enables people to simply take pictures of their food for a visual diet diary or journal. This app (available from the iTunes store and PhotoCalorie.com) then calculates the calorie content AND nutritional make-up of the meal after the dieter enters a brief description. Even if you’re not counting calories, the visual diet diary allows you to analyze and track your dietary patterns and habits which are, in the long run, the key to success.
