It’s been widely reported that Americans are drinking more during the COVID-19 pandemic. And we all know the health consequences of too much alcohol.

But how does obesity enter into the risk equation?

Well, a recent study looked at alcohol intake in relation to body mass index (BMI). Researchers found an increased risk of developing fatty liver disease and all-cause mortality.

Obesity and Fatty Liver Disease: A Study

The study reviewed 18,506 patients without fatty liver disease (FLD). Participants were classified by alcohol consumption status: non-drinkers, moderate drinkers, and heavy drinkers. The patients were followed for about 6 years.

And what did they find?

Moderate Drinking & Obesity

The risk of developing FLD or all-cause mortality in moderate drinkers varied. Those with normal weight were at a reduced risk. But individuals with obesity were at a greater risk.

This supports the current recommendation that individuals with obesity should not consume alcohol. Even low alcohol intake may not be safe.

Moderate Drinking & Normal Weight

For normal-weight individuals, moderate alcohol intake may be safe and even offer liver protection. Decreased insulin resistance, improved lipid profiles, and anti-inflammatory properties may be the reasons.

The survival benefit of moderate alcohol use was not found in those with obesity.

In Summary

Moderate alcohol intake is a risk factor for FLD in individuals with obesity, but protective in those with normal weight. As a result, alcohol consumption should be avoided in individuals with obesity.

People with fatty liver disease who continue to consume alcohol may be at risk of developing cirrhosis. If you think you may be at risk, eliminate alcohol consumption and talk to your physician.

Nick's Story

"I wish I would have come here first. We spend all our time reacting to the next great weight loss tip or program. It might work for a while, but does not last and we end up yo-yoing from one fad to the next – as we gain more weight." Read More

   Trustindex verifies that the original source of the review is Google. I cannot say enough wonderful things about Dr Robert Ziltzer! He helped me reach my ideal weight and more importantly maintain it for over 2 years. He has also helped me keep my blood pressure exactly where my internist wanted it. Dr Ziltzer is not only exceptional in weight management but also a truly gifted internet’s. His knowledge, kindness, and dedication are remarkable. I am deeply grateful for his care and recommend him whole heartedly!

Everyone at the center was caring and friendly, from Bianca, at the front desk, to Lily, who is the MA.  Kristen listened to my frustrations and prior disappointments about what has not worked, and is confident that she can help me achieve my goals of weight loss.  I am looking forward and excited to see the success I will attain.

   Trustindex verifies that the original source of the review is Google. I'd lost 20 pounds on my own and struggled to keep it off.  I decided GLP-1 meds were the next step in losing more and keeping it off.  I wanted a medical doctor supervised program and chose SWLC. I am so very glad I did!  The team in Glendale is so supportive and kind; and when I feel discouraged, they pick me up with positive energy and input.  They really do a great job with encouragement all the time. 6 weeks in I've lost 17 pounds, and am approaching weight loss with a very new perspective.  Also knowing that when I reach my target goal, they'll be there through maintenance and beyond is encouraging as well.  Good to not feel alone on this journey.
