I've recently downloaded the Noom application on my smartphone. It's basically a weight-loss application which sets tasks for me to do, encouraging me to eat healthy snacks and to walk more (it has an in built pedometer function). What sets it apart from other applications is that I don't have to search specific food types like in myfitnesspal.. it split food groups into green, yellow and red - good, ok and bad foods. Genius!
I've only been using it for 3 days and have lost 0.5kg which I credit to eating less crap throughout the day.
Hopefully I'll be able to lose weight (I put on 5kg in 2 years!!).. and be bikini-beach-ready for summer!
