Test Text1 plain Now, to the secrets the pros are not revealing. We've been working with "read "readers' digest" to bring you what the pros won't tell you.

Do not arrive at a training session in the following state -- on an empty stomach? Coming off a cold or a stomach bug? On four hours' sleep. Or any of the above? "D" come ready to roll. If you are feeling rundown, do something different. Like go for a walk. Or do some yoga.

Here's a problem. You go to a dinner. A party. And you're not really in control of what's being served. How do you handle that? The number one is just make yourself useful. Get up, help the host set the table. It gets you away from your plate. But you're part of the social interaction. I'm like, ding, ding, ding. Does sweet play a role in hunger?
