Today is a big day of eating, giving thanks with your family, eating, relaxing in front of the TV, and more eating.
If you've got goals that don't include gaining weight, this is a problem.
What to do?
Remember - it's just one day.
If you let it extend into the next day, and the next, and the next after that . . . and begin a month-plus long binge of eating that doesn't end until your New Year's Resolutions kick in . . . then it's a problem.
If not, it's just one day. It won't make or break your diet, your training, or your results. Enjoy the day. Enjoy the day, enjoy the company, and get back into your training on Friday. Consistent work and attention to diet day in and day out is what gets you results.
