Alcohol and Your Health: Sleep, Weight, Liver, and What the Guidance Says Now
Nutrition · Real life
No lecture. Just what alcohol does in your body, what the guidance says now, and how to drink less if you decide you want to.
Written for my patients. If you are not one, read "call me" as "call your own clinician", and take the questions here to them.
I do not ask about alcohol to catch anyone out. I ask because it touches almost everything else I am trying to help with, and because most people have been given information about it that has since turned out to be wrong.
The "healthy glass of wine"
For years, studies suggested light drinkers lived longer than people who did not drink at all. It was a comforting finding and it made its way onto a lot of dinner tables. When researchers looked more carefully, much of the effect came from who ends up in the non-drinker group: people who quit because they were already sick, which made the abstainers look worse than they should have.
A 2023 analysis of 107 studies and nearly five million people corrected for that and found no survival benefit from low-level drinking. The glass of red wine was never doing what we hoped.
What the guidance says now
The 2025–2030 Dietary Guidelines, released in January 2026, dropped the old limits of one drink a day for women and two for men. They now say only to consume less alcohol for better overall health. The main society of U.S. liver specialists publicly objected to removing the clear limits, and I understand why: a number, even an imperfect one, is something people can actually use.
A year earlier, in January 2025, the U.S. Surgeon General issued an advisory that alcohol is a leading preventable cause of cancer, linked to about 100,000 cancer cases a year in this country.
What it does in your body
What counts as one drink
| Drink | One standard drink |
|---|---|
| Wine | 5 ounces at 12 percent. Most restaurant pours are larger. |
| Beer | 12 ounces at 5 percent. Many craft beers are 7 to 9 percent, closer to two drinks. |
| Spirits | 1.5 ounces at 40 percent (80 proof). |
If you want to drink less
- Decide before you go. How many, and which nights. Plans made in advance hold better than decisions made with a drink in hand.
- Alternate every drink with water or something sparkling. Non-alcoholic beer and spirits have gotten good.
- Keep a few alcohol-free days every week, not just a dry month once a year.
- Notice what you are drinking for. Stress, sleep, habit, socializing. Each of those has a better tool, and naming the reason is most of the work.
- On a GLP-1? Many people notice they simply want less. A small 2025 trial found semaglutide reduced drinking in people with alcohol use disorder. Alcohol can also hit harder on these medications and worsen nausea.
Tell me if
You have tried to cut back and could not. You drink in the morning. You feel shaky, sweaty or anxious when you stop. Stopping suddenly after heavy daily drinking can be dangerous, so please do not do it without a plan. Treatment works, there are medicines that help, and none of this changes how I think of you. You can also reach SAMHSA's National Helpline, free and confidential, any hour.
I wrote this for my patients, and it reads the same for everyone: general information, not a plan. If you would like your own numbers read against your own story, that is what a Lab Second Look is for. If you are not sure where to start, the free intro call is fifteen minutes.
A note on how to use this. General information for my patients, not individualized advice. Do not drink at all if you are pregnant, trying to conceive, or recovering from alcohol use disorder.
