Alcohol doesn't stop weight loss completely, but it makes it a lot harder. Drinks add calories, drinking makes you eat more, and alcohol disrupts your sleep, which makes you hungrier and less likely to train the next day. You can still lose weight while drinking if your drinks fit into a small calorie deficit. For most men, that means cutting back, not cutting out.
If you want a full plan that puts training and food together, follow the 4-week restart plan for men over 30.
How does alcohol slow down weight loss?
Alcohol slows down weight loss in four ways. Drinks have plenty of calories, drinking tends to increase how much you eat, alcohol makes sleep worse, and a rough morning often means a skipped workout and a bad food day. Each one is manageable on its own. Together, on a regular basis, they can cancel out a week of good choices.
1. The calories in the drinks
According to MedlinePlus, a regular 12-ounce beer has about 153 calories, a light beer about 103, a 5-ounce glass of wine about 121 to 129, and a shot of 80-proof spirits about 97. A couple of drinks out can add 500 calories or more. Those calories count just like food.
2. The food that comes with drinking
A 2019 review in the British Journal of Nutrition of 22 studies found people don't eat less to make up for alcohol, and that drinking tends to increase food intake. Bar snacks, late-night pizza and the hangover breakfast all add up.
3. Worse sleep
Alcohol reduces REM sleep, even at around two drinks, according to a 2025 meta-analysis in Sleep Medicine Reviews. Poor sleep makes you hungrier and more tired the next day.
4. The lost next day
A heavy night often means skipping the gym, ordering takeout and spending the day on the couch. That's a double hit: fewer calories burned and more eaten.
It's rarely the beer alone. It's the beer, the wings, the late pizza and the wasted Sunday.
Can you drink and still lose weight?
Yes, you can drink and still lose weight, as long as your total calories for the week stay in a small deficit. That usually means drinking less often, drinking fewer drinks when you do, choosing lower-calorie options and planning the food around it. Most men can keep their social life and still lose weight steadily.
A simple framework:
- Set drink-free days. Monday to Thursday off is a common starting point.
- Decide your limit before you go out. Two or three, not "we'll see."
- Eat a proper meal with protein first. You'll snack less at the bar.
- Swap to lighter drinks. Light beer, or spirits with soda water.
- Alternate with water. One drink, one water.
- Plan the next morning. Have breakfast and a walk lined up.
When you're ready to put numbers on your week, here's how to calculate a calorie deficit without obsessing.

Does alcohol affect muscle and training?
Heavy drinking can affect muscle and training. A 2014 study in PLoS One found that drinking about 12 standard drinks after a hard workout reduced muscle protein building by 24%, even when protein was eaten too. A beer or two won't do that, but regular heavy nights make it harder to keep muscle while you lose fat.
That matters because the goal isn't just to weigh less. It's to lose fat and keep muscle, so you look and feel better at the end. More on recovery in why recovery takes longer after 30.
What do US guidelines say?
The Dietary Guidelines for Americans, 2025 to 2030, advise people to "consume less alcohol for better overall health." They no longer give a specific daily number. Some people shouldn't drink at all, including those recovering from alcohol use disorder and those on medications that interact with alcohol. If you're unsure, ask your doctor.
What's the best first step?
The best first step is to count your drinks for one normal week. Write down every beer, glass of wine and shot, then multiply by the calories above. Most men find drinks make up a bigger share of their week than they expected. Once you see the number, cutting back becomes an obvious, specific target instead of a vague promise.

Your next step
Alcohol doesn't stop weight loss, but it slows it down through extra calories, extra food, worse sleep and lost days. You don't need to quit. Count a normal week, set drink-free days, plan your nights out and fit your drinks into a small deficit. Then start the 4-week restart plan and make counting your drinks the first thing you do.
