Hi Marvin

Losing 13 pounds in one week is excellent news. Yes it is fast, but you do not say how much you weigh to begin with. I suspect that it is quite a lot and you don't want to own up to it! If that is so then 13 pounds is fine. Keep on induction for the next week and then start to increase your carbs.

A lot of what you have lost so far is water that was associated with the carbs in your body, now starts the real process of losing body fat. After the first 2 weeks you should aim for a weight loss of no more than 3 pounds a week. Doing exercise is great as it will tone up your muscles, give you a better body shape and convert that fat to muscle.

Yes, your age does help as well as being male!

Go on, own up to what you weight and what you would like to slim down to.

Continued success.
