I have been working out and clean eating just recently. Decided to get my health on track. For the first week I did some moderate workouts and I lost some weight. I decided on my 2nd week to amp it up and since then I've been doing some intense workouts. In 3 weeks I lost 10 pounds, but for some reason in my 4th week I've only lost half a pound. My workouts haven't changed too much except that my weights have increased a little bit. My eating I admit isn't 100 percent clean its like 95 percent. Why haven't I lost too much this week? Is that normal? Sorry if its stupid but I'm new to this.
