Coaches are taught that people can know what to do, but if there is no action then there is no forward movement.
I've been at fatsecret for a year and I've observed a few things.
1. The people who post continually and participate in more than one group + challenges are more likely to lose
2. People who log into fatsecret more than once a week are most likely to lose weight or at least, not gain more, than those who only log in once or twice a month.
3. Loging in appears to help people avoid cheating and keep on goal.
4. People who log in their food and exercise are most likely to succeed in the long-term. This may be due to the fact that they are less likely to quit.
As long as you try, and try again, you will never fail. You never lose. The only way to truly fail is to quit.
