Can a Low-Carb Diet Help Close Racial Gaps in Obesity?

Main Takeaways

Some racial and ethnic groups, including Black individuals, tend to produce more insulin in response to high-carb meals. This may increase the risk of obesity and diseases related to insulin resistance.

A new clinical study suggests that Black women who are high insulin producers benefit significantly from a low-carbohydrate diet.

For people at high risk of insulin-related obesity, reducing carbs—rather than just calories—may be key to reducing health disparities.

How Long Does It Take to Lose Weight?

“How long will it take me to lose weight?”

It’s a common question—and an understandable one. If you’re making the effort to change your habits, it’s natural to want to know when you’ll start seeing results. But the answer isn’t a simple number or timeline. In fact, it’s a bit like asking, “How long is a piece of string?” The truth is: it depends.

Why Short-Term Diet Trials Can’t Solve Chronic Disease

Originally published in STAT News on April 22

Imagine a clinical trial involving sedentary, overweight adults. One group continues their inactive lifestyle, while the other begins an intensive regimen of daily running, calisthenics, and sports. After just a week or two, participants in the exercise group would likely feel sore, fatigued, and possibly even show a temporary drop in performance. No one would seriously conclude from this short-term snapshot that exercise is harmful. It’s clear we’d need a longer trial to understand the benefits of physical activity.

The Three ‘Whys’ of Weight Loss — Homeostatic Hunger

In the mid-2010s, there was an overwhelming sense of optimism in the medical and public health communities—a belief that we were on the brink of solving the global obesity crisis. The answer, it seemed, wasn’t a pharmaceutical breakthrough or a revolutionary diet plan, but rather bariatric surgery. Popularized through shows like My 600-lb Life, which chronicled extreme weight loss journeys, these procedures seemed like a miracle. Patients lost hundreds of pounds, reversed diabetes, improved mobility, and often gained back years of life. For a while, it looked like obesity had met its match.
