Were you walking to the cake shop and back?

Haha no unfortunately

That's pretty much textbook why exercise on its own will not reduce weight. You need to control your intake as well.

There is some evidence that we offset all that activity later in the day. I know that if I go for a long bike ride then I will inevitably veg out in front of the TV later.

Exercise is important but it's not because of the burning of calories.
