Losing the Same Weight Didn’t Produce the Same Health Benefits
Confirmed
In Short: The study underscores the benefits of weight loss itself, as all three diets improved metabolic health.
A new study published in the journal Cell Metabolism reveals that weight loss from different diets can have varying health impacts, even when the amount of weight lost is the same.
Among several diets tested in a clinical trial, a ketogenic diet produced the greatest improvements in liver and metabolic health, according to Samuel Klein, MD, the Danforth Professor of Medicine and Nutritional Science at Washington University School of Medicine.
Despite the diets containing very different proportions of carbohydrates, fat, and protein, all three groups lost about the same amount of weight, but the ketogenic diet produced larger improvements in liver fat, liver insulin sensitivity, and blood sugar control.
However, the findings suggest that the type of diet used to achieve weight loss can influence the extent of health benefits.
Petersen, another researcher involved in the study, noted that weight loss — even just a moderate amount — is universally beneficial in people who are metabolically unhealthy.
The study highlights the importance of considering the specific health benefits of different diets when recommending weight loss strategies for individuals with obesity, prediabetes, and fatty liver disease.
What's confirmed
- Democratic-led states and cities are challenging a federal rule they say gives President Donald Trump’s administration broad discretion to deny green cards to immigrants who use food stamps and other public benefits.
What's still developing
- “This rule preys on that fear and counts on families forfeiting the food assistance, health care coverage, and other public benefits to which they are legally entitled,” she said Monday at a news conference in City Hall alongside New York City Mayor Zohran Mamdani and immigrant advocates.
- Specifically, James said, the rule unlawfully gives immigration officials broad discretion to consider a wide range of public benefits when making their decisions on immigrants seeking legal status in the country.
- That means a parent’s green card application could be at risk simply because their U.S. citizen child used state-provided health insurance or participated in a school’s free lunch program, James said.
