A recent study seems to suggest that vigorous exercise does help in burning fat, but it also increases appetite.  Apparently, our body has a tendency to maintain our current weight, whatever it might be.  The key is apparently to burn calories on the sly, without triggering the compensating appetite.
So – in addition to standing around a lot as suggested by the article, consider the following three ways of sneaking exercise into our day by marrying mini-workouts with every day tasks:
Walk ‘n Talk
Turn your tete-a-tete with a colleague into a brisk …

I’ve never liked vegetables.  Except tomatoes.  Except a tomato, technically, is not even  a vegetable.  Getting the five-odd servings a day has always been a struggle.  Frankly, I didn’t worry about it too much.  After all, I was fine, healthy, bounding with energy and all around feeling-goodness.

Boost productivity: Set the timer for a 15 or 30 minutes to focus on a task and commit to it completely till the timer goes off.  You’re only committing for 15 minutes.  Totally doable.  This also works …
