Can you blow your diet for one day and still lose weight?

Yes , you can blow your diet for one day and still lose weight, depending on how far along you are in your diet. If you just started within a few days to a week and you "pig out" immediately, you are not going to lose weight. However, if you have been on your diet for enough time to have noticed weight loss , more than likely , you have increased your metabolism and your body is now capable of burning fat quicker and easier than before. It is actually good to pick one day out of a week to indulge yourself in foods that you forbid yourself on a diet (foods within reason, of course) because it mixes things up a bit and can actually increase the speed of your metabolism even further.
