We need some way to correlate weight-gain/loss to nutritional intake, life style. That will probably provide a better feedback than just knowing one aspect.
Great info. Thank you.
I’m curious to hear what people think these sites/apps are doing well, and what they wish they did (or think isn’t being done well). I’m working on a new fitness mobile app and site and would love to get your thoughts.
Thank you!
I have been using TheCarrot.com for the past few months for a weight loss journal and to manage my asthma.
My favorite new startup is Lollihop. I heard the co-founder Suzanne Xie at Harvard recently and she was amazing. The site will help you to build a team to lose weight. It is so cool thus far and I can use my Withings scale!
Have fun Lollihopping!
