Are You Fit to Climb the Corporate Ladder?
Instead of sitting down to a high-calorie lunch, round up some coworkers and go on a heart-pumping walk. If you can't indulge in that afternoon workout to cure the post-lunch slump, then don't rely on that other standby - sugar. Try a snack that has some protein to give your body and brain a boost.
And if you need a second cup of coffee, then it's probably fine to indulge.
