Crunches address your abdominal muscles, but you also need to do exercises to hit the other major muscle groups including the legs, hips, shoulders, chest, back and arms. At least one set of eight to 12 repetitions of exercises for all of these muscle groups -- including crunches -- completes a total body routine and will help tone your stomach area faster than crunches alone. Once you can do that without getting too tired, repeat each exercise set two or three times, or make them harder by adding weight. The important thing is to continue challenging your body if you want to see continued improvement.
If this problem does apply to you (the problem being "estrogen dominance") it will be like a light bulb going off in your head as you are reading this book. Even if you are relatively young, if you've been subjected to long-term chronic stress (longer than 3 months), this can be significant enough to have shifted the cortisol in your body and to have affected your hormonal balance. If you have not changed your eating, are exercising about the same amount, and have not made any other lifestyle ch ...more
"Researchers are now discovering that gut bacteria also seem to play a role in the complex process of weight loss and weight gain," he writes. "We don't know exactly how much impact our Little Buddies have on our weight, but we're learning enough to believe that understanding the connection more fully may help us as we confront the obesity epidemic in the United States — and in our own bodies."
It's an all-too-common problem once you hit thirty: Despite your best efforts, you just can't seem to lose the extra weight around your middle, and you look in the mirror wondering what month and year you lost your waistline. Medical research proves you're not alone—that the average American gains one to two pounds a year after age thirty—usually around the stomach. Not only does this excess belly fat make you look and feel bad, it's the most damaging kind of fat; a precursor to heart attacks and certain types of cancer. 

In fact, weight-loss research proves that because of shifting hormone production, the average person will add one to two pounds around his or her middle each year between the ages of thirty-five and fifty-five. As long as your body's cellular metabolism is compromised by an untreated hormone imbalance—most particularly estrogen dominance—the extra pounds around your middle will be nearly impossible to lose.

It’s not just about weight loss. Having great gut health is linked to good health throughout your body. Scientists in this rapidly growing field are finding connections between gut microbes and the  immune system, weight loss, gastrointestinal health, , allergies, asthma, and even cancer. With every study that’s published, scientists become more convinced that having a healthy gut leads to having a healthy body.
