Will my metabolism slow down if I'm not eating as much as I used to?

Not at all. In fact, Shivercise and Tightercise can speed up your metabolism. So rather than eating in the morning to get your metabolism started, you can Fastercise to boost your metabolism. You won’t feel as hungry throughout the day, and that’s a sign that you’re using your stored fuel (fat) as your energy source. If you find that you go long stretches of time throughout the day without feeling hungry, and you’re maintaining your Fastercise program, this is a sign that your body is maintaining itself with its stored fuel. You will likely see weight loss in the days to follow as well.
