Summary:

Dr. Bikman explains why losing a large amount of weight can sometimes cause the body's metabolism to slow down more than expected.

He uses contestants from The Biggest Loser as an example. Six years after their dramatic weight loss, many had regained much of the weight, yet their bodies were still burning approximately 500 fewer calories per day than expected for their size. This phenomenon is called metabolic adaptation.

Ben explains how hormones such as leptin, insulin, and thyroid hormone influence this process. As body fat decreases, leptin falls, signaling the brain to increase hunger and conserve energy. The body may also reduce spontaneous movement and other energy-consuming activities, making it increasingly difficult to maintain weight loss.

The encouraging news is that the way someone loses weight can make a difference. Ben reviews research suggesting that lower-carbohydrate diets may help preserve energy expenditure after weight loss, particularly in people who produce more insulin. He also emphasizes the importance of eating sufficient protein, maintaining muscle through resistance training, and staying physically active throughout the day.

The central takeaway is that successful weight loss isn't just about losing pounds—it's about protecting your metabolism and developing habits that make the new weight easier to maintain.

Dr. Bikman explains why micronized progesterone should not be confused with the synthetic progestins historically used in many hormone therapies. Micronized progesterone is chemically identical to the hormone produced naturally by a woman’s ovaries, while synthetic progestins can also activate cortisol- or testosterone-related receptors, potentially affecting insulin sensitivity, blood lipids, and other aspects of metabolic health.

Ben reviews clinical evidence showing that micronized progesterone can effectively protect the uterine lining when estrogen is used while preserving more of estrogen’s favorable metabolic effects. Oral micronized progesterone is also converted into allopregnanolone, which enhances the brain’s calming GABA signaling and may improve sleep. Better sleep itself can support insulin sensitivity, while progesterone may also reduce hot flashes and night sweats that interfere with sleep.

The safety evidence is also encouraging. Compared with some synthetic progestins, micronized progesterone appears more favorable with respect to blood clots, breast cancer risk, and metabolic markers. Ben’s overall conclusion is that for women using menopausal hormone therapy who need progesterone to protect the uterus, micronized progesterone appears to be a metabolically favorable partner to estrogen.

Summary:

Dr. Bikman explains why some people may produce an inadequate GLP-1 response and how insulin resistance could be part of the problem. Because intestinal L cells have insulin receptors, chronically elevated insulin can make these cells insulin resistant, reducing their ability to release GLP-1 and potentially creating a cycle of faster stomach emptying, higher glucose, more insulin, and further impairment of the natural GLP-1 response.

Ben uses this physiology to explain how he believes GLP-1 medications should be used: not simply to produce maximum weight loss, but as a temporary window in which carbohydrate cravings become easier to control. Rather than escalating automatically to the highest tolerated dose, he favors using the lowest dose that makes refined carbohydrates easier to resist while still requiring the person to exercise some choice and discipline. During that window, the goal is to establish meals centered on protein, healthy fats, and whole foods while improving sleep and resistance training.

Ben also addresses concerns about lean-mass loss, explaining that body-composition scans can classify losses of water, glycogen, organ fat, and even the non-fat portion of adipose tissue as “lean mass.” Ultimately, he argues that GLP-1 therapy should have an exit strategy: improve insulin sensitivity, restore the body's own GLP-1 signaling as much as possible, establish sustainable habits, and then work with a clinician to gradually reduce the medication rather than assuming it must be permanent.
