77: Dr. Bill Campbell: The Weight Loss Resistance 75–80% of Midlife Women Say They're Facing (And Why Your Scale May Not Be Budging Either)

One thing I hear all the time from women in perimenopause is how confusing weight loss can suddenly become. They try the diet everyone online is swearing by. The scale does not move. They tighten things up. Still nothing. And somehow the advice keeps coming back to the same thing: eat less.

But how long can "eat less" be the answer before we start asking a better question?

That is what made this conversation with Dr. Bill Campbell so interesting to me. He is studying women who already exercise and pay attention to nutrition to figure out whether weight loss resistance during the menopause transition is actually real, or whether something else is getting blamed on hormones. In his preliminary survey, roughly 75 to 80% of peri- and postmenopausal women reported experiencing weight loss resistance. The number is huge, but the WHY behind it is what he is trying to uncover.

Dr. Bill Campbell is a professor and director of the Performance and Physique Enhancement Laboratory at the University of South Florida. He has spent his career studying fat loss, resistance training, and body composition, but his own wife's experience through menopause made him realize there were questions his research still could not answer.

22:17 Whether weight loss resistance in perimenopause is actually real, and what the 75–80% number really tells us.

26:39 What happens when cutting calories even lower still does not get the scale moving.

32:09 How much protein women may actually need to protect muscle while working on body composition.

41:07 Why years of dieting and repeated weight-loss cycles may matter more once midlife hits.

51:46 How heavy women really need to lift in their 40s and 50s, especially when strength training is new.

1:02:16 Where hormone therapy fits into the weight conversation, and why the research is not as simple as "estrogen makes you lose weight."

If the scale feels a whole lot more stubborn in midlife, this episode gets into the research behind why "just eat less" may be way too simple of an answer.
