Caloric Intake: A Hidden Killer for Men with MASLD?

A groundbreaking study has unveiled alarming connections between daily calorie consumption and overall mortality rates among men suffering from metabolic dysfunction–associated steatotic liver disease (MASLD). While both low and high caloric intakes increase death risks, this troubling pattern appears to spare women from similar dangers.

With MASLD impacting nearly one in three adults in the US, the disease is notorious for its ties to both diabetes and sky-high mortality rates. Yet, experts are baffled by the lack of solid nutritional strategies to combat this condition.

The Study: Insight from 2,500 Participants

To shed light on the issue, researchers analyzed data from about 2,500 adults with MASLD gathered through the Third National Health and Nutrition Examination Survey. Participants provided a 24-hour dietary recall to assess their total energy intake, categorizing them into low, moderate, and high-calorie consumers. Mortality data were meticulously tracked, resulting in an average follow-up period of over 22 years.

U-Shaped Curve: The Grim Reality for Men

The findings exposed a U-shaped relationship between calorie intake and all-cause mortality, strikingly evident in men. Those who consumed fewer than 2,000 calories per day faced a staggering 35% increase in mortality risk compared to their counterparts with moderate intake (2,000 to 3,000 calories). Even more shocking was the 54% higher risk observed among men indulging in over 3,000 calories a day.

In contrast, women exhibited a much weaker connection between calorie intake and mortality, suggesting that the body's reactions to caloric consumption vary dramatically between sexes.

Why the Gender Gap? Secrets of Survival.

Researchers hypothesize that the notable sex-based difference may stem from biological factors. Women’s bodies tend to rely on lipid oxidation during food shortages or exercise, allowing them to preserve protein mass better than men. Additionally, hormonal differences, particularly estrogen's role in minimizing insulin resistance, may offer women a protective shield against diabetes.

Caloric Extremes: A Double-Edged Sword

The study also uncovered that both under-eating and overeating are significantly linked to increased cancer mortality within MASLD patients, with low intake leading to a 45% increased risk and high intake skyrocketing it to a staggering 94%.

Interestingly, no substantial links were found to cardiovascular or diabetes-related deaths, although low and high caloric consumers displayed unique health profiles.

Crucial Guidance for Health Management

These findings stress the dire need for revised nutritional guidelines for men battling MASLD. Careful calorie management might very well become a key strategy in combatting the grim prognosis linked to this liver disease.

As researchers continue to delve into the intricate dynamics of caloric intake and health implications, one thing is clear: understanding how energy consumption impacts mortality could save lives.
