My Husband Lost Weight and I Didn't — Why?

"My spouse was able to lose 70 pounds when I started cooking with low glycemic foods. Why does this not work for me?"

Four separate readers have sent a version of this, and it is one of the most demoralizing experiences in this whole area — partly because of what it seems to imply about you.

It implies nothing about you.

He wasn't running the same experiment

You changed the food in one kitchen, so it looks like one experiment with two participants. It isn't. It's two experiments that happen to share a menu.

Muscle mass. Men typically carry considerably more, and muscle is the body's largest site of glucose disposal. More muscle means more capacity to absorb what arrives.

Where fat sits. Men store more visceral fat, which is the metabolically active kind. It's more dangerous, and it's also more responsive — it goes first.

Hormones. Estrogen influences where fat is stored and supports insulin sensitivity. As it declines, storage shifts toward the abdomen, and the visceral fat that accumulates there is strongly associated with insulin resistance.

Researchers still debate how much of that insulin resistance comes from the hormonal change itself versus from the redistribution. What isn't debated is the redistribution, or what visceral fat does once it's there. Add the muscle loss that comes with this stage of life and you have the full picture.

Starting point. If he was carrying substantially more weight, early losses are larger. That's arithmetic, not virtue.

What this means practically

You are not doing it wrong, and you don't need to eat less than him to catch up.

Protein, higher than feels necessary. The threshold that matters after fifty is 25 to 30 grams per meal, and most women are well short at breakfast. This is the biggest lever you have, and the one his body doesn't need as urgently.

Resistance training over cardio. You're protecting the tissue that does the glucose disposal. He has more of it to spare.

Judge by something other than the scale. Waistband, energy, the afternoon crash, sleep, your next A1C.

Give it longer than he needed. Your timeline is different and that isn't a failure of the approach.

The thing worth saying plainly

Watching someone eat your cooking and get the result you wanted is a specific kind of hard. You did the work. The cooking that produced his 70 pounds was yours.

Try this week: add protein to breakfast and pick one measure other than the scale to track for a month.

Education, not medical advice.
