I wish that the study did not focus just on middle-aged folks... people in their late 20's onward aren't normally slim like they were as the norm, 30 years ago. Witness the cut and style of women's clothing now compared to back then.

Good habits start before hitting your late 40's and upward. While it's true that for many women in perimenopause and menopause, metabolism may slow down a tad without exercise and diet changes, it should be an alert for younger women who need to make changes now before mid-life.
