1,000 Calorie Challenge

i wouldnt suggest going on any 1000 calorie diet. if you cut to many calories of your diet then you are going to go into stravation mode. looks like you have done a great job in your journey. you might try changing up your exercise routine. i dont think the last 30 is going to come off as easy as the first 30.

I'm not familiar with the workout/challenge. Are you trying to consume less than 1000 calories a day, or trying to burn an extra 1000 calories? I would completely avoid the former. As mentioned by Dafrog, you'll probably end up putting your body into starvation mode. At the very least you'll end up throwing your metabolism out of whack once you trying eating normally again. If you're going for the later, I routinely burn between 1000 and 2000 extra calories per day when I'm at the gym (down 18 pounds in seven weeks). Somedays are harder to keep the intensity up than others, but it's not impossible and I don't feel weak or fatigued (other than the expected light soreness form the weightlifting).

Has anyone tried the 1,000 Calorie Challenge/Six Pack Abs Project? Was just looking at it and wondering if it's worth it. I have 30 lbs left to lose, and I want to be one hot mama when I'm done.

If you've tried it: How are the workouts (besides challenging)? Exactly what do you do? I have access to a gym, and when I do go, I'm there for an hour or two. I don't mind a little hard work. Heaven knows I've put some in to drop nearly 75 lbs!

The hard part is that it's more about patience than hard work. I'm pretty close to my target weight and have had a real hard time dropping lately. Still, eating less than before to speed things up isn't the answer since it is natural for the progress to slow as fat becomes scarce. It gets harder to access the remaining fat storages which leads to muscle tissue becoming more and more attractive source of energy for the body. To minimize the loss of muscle tissue you need to make sure the deficit doesn't get much greater than 300-500 Kcal a day when you get close to your goal.
I don't know what the "1,000 Calorie Challenge/Six Pack Abs Project" is but if it includes restricting daily consumed Calories to 1000 Kcal, it sounds like it's tailored to burn the abs away and keeping the fat..
