Postmenopausal women are at an age where they get this little bump in weight. Following this diet isn't going to cause a weight gain.

Participants in the two intervention groups made greater changes than those in the control group and saw the greatest benefit in blood pressure status. This shows that people at risk for heart disease can successfully and simultaneously make multiple changes in lifestyle, for a substantial benefit.

We really need to see the results of the trial to see whether following this diet is good for cancer or cardiovascular disease. Let's see what happens.

You had this population-wide reduction (in fat). Everyone heard about fats. We wanted to get saturated fats down. One way to do that was to lower total fats. That was the public health message.

These results do not support previous notions that a low-fat diet is the cause of the obesity epidemic. This pretty much shows that certain things we do now are healthful, such as low saturated fat intake.

People have been questioning whether low-fat diets are good. Just as the percentage of fat in diets has been decreasing since the late 1970s, at the same time the prevalence of obesity has gone up. Is there a connection?
