Weight Loss

After success on the Nutrisystem program, but unable to afford it anymore, I bought this book to try to bring the diet into my kitchen. It was not a mistake, but not as helpful as I'd hoped. Kind of a sales pitch for the diet plan, not as many recipes as I'd hoped.

Older book not up to date. Very good way of eating and easy to follow recipes and menu building. I've gifted this book during one of my relocations and it's helped the recipient. I lost 20lbs in 2 months. This is an excellent program. I haven't had much discipline when it comes to what I eat and this is the only program I've tried that really works and did not leave me feeling cranky and deprived. I lost 20lbs without exercise in the first 2 months and am continuing to lose 2lbs a week.

The weight loss has given me so much energy that now I can't sit still so exercise fit itself into the plan without being forced. This program works if you love to cook I don't and if you like convenience of prepackaged food I do.

I'm never hungry on this program because I eat 5x a day. The web site is informative and teaches proper portion size and a healthy mix of protein, carbs and fats. This book takes it the extra step to really explain what is behind the program so you can maintain the weight loss easily. I now know that my slow metabolism was due to blood sugar fluctuations.

My metabolism is no longer slow and my blood pressure is textbook-perfect. Don't wait, start the program today and feel better almost immediately. It really does work and it is very easy!!!

The machine that is supposed to get you the most fit; the one that burns the most calories; or the device that has least impact on your joints? These are all valid concerns -- but none of these is the most important question you should be asking yourself, says exercise physiologist Bryant A.

Which machine do you really want to use? So instead of choosing the treadmill for the calorie-burning factor, or the elliptical trainer your friend recommended, figure out which machine feels best to you, he suggests. Nashville exercise physiologist Kathy Alexander agrees: But how do you know which machine is likely to feel right to you?

Here's what you can expect from the most popular cardio machines out there, along with some tips on getting the most out of your workout. Here's the lowdown on what you can expect from some of the machines you're likely to find at your local gym. The treadmill burns the most calories of any of the cardiovascular machines available at most gyms, says Alexander. You can expect to burn about calories per mile, walking briskly. Stamford notes that a treadmill can be adapted to many different fitness levels by increasing the speed from walking to running or by adjusting the incline.

But even walking may be too much for someone who is overweight and has joint pain. Every time your foot hits the ground, says Alexander, "the impact forces are 3. Since a treadmill is moving under you, the impact may be slightly less than that. One more thing to keep in mind: Treadmills can pose a real balance challenge for new exercisers or those who haven't worked out in a while, says Matthew Vukovich, exercise physiologist and associate professor at South Dakota State University.

These machines pack a little less punch on the joints, and either can be a good alternative to the treadmill, says Vukovich. Because you use them in a standing position, you're using lots of muscle mass, so the calorie burn rate is still pretty high.

Elliptical machines with arm components can further increase the numbers of calories you burn, says Stamford. All our experts agree that the stationary bike offers the workout with the least impact on the joints. People with knee pain are often steered toward these bikes, since the impact of body weight is not a concern as it is on a treadmill, elliptical trainer, or stair stepper.

But to avoid knee strain, you must make sure the bike is adjusted to fit your body, Vukovich says. Most people sit too low, meaning their knees flex too much as they pedal. This can put too much pressure on the knee and result in soreness, warn Vukovich. The stationary bike is a less intense calorie-burner than some of the other machines. You'll need to pedal four miles to burn calories, says Alexander. Rowers are more advanced cardiovascular machines. Because you must push with the legs while you pull with the arms, rowers require coordination.

They also you require you to engage your core abdominal muscles to support and protect your back. Because they use so many muscle groups, rowers burn lots of calories. But this machine has several red flags for a beginning or unfit exerciser.

Extra weight often comes with back pain , and this is not a machine you want to use if you have back issues, he says.
