You did the hard part. You survived the weddings, the awkward happy hours with soda water, and that one Friday night when everyone was doing shots and you were just... not. Half a year has passed. Your skin probably looks better, your sleep is deeper, and your bank account is definitely healthier. But then you step on the scale and realize you’ve experienced 6 months no alcohol and no weight loss.
It feels like a betrayal.
We’ve been sold this narrative that booze is just "empty calories" and cutting it out is a magic metabolic lever. While it's true that a standard IPA has about 200 calories and a large glass of wine sits around 150, the math rarely works out as a simple 1:1 subtraction in the real world. If you were drinking three beers a night and cut them out, you "should" be down twenty pounds by now.
But you aren't. Honestly, it’s frustrating as hell.
The Sugar Swap Nobody Warned You About
When you stop drinking, your brain loses its primary source of easy dopamine and quick-burning fuel. Alcohol is basically liquid sugar for the metabolism. When that’s gone, the "Sugar Dragon" wakes up. Most people I talk to who hit the six-month mark without losing an ounce eventually admit—after a bit of prodding—that they’ve been crushing pints of Ben & Jerry's or keeping a "survival stash" of gummy bears in the pantry.
It's a biological pivot.
Your body is seeking a neurochemical replacement for the ethanol. This isn't a lack of willpower; it's a physiological response. Dr. George Koob, director of the National Institute on Alcohol Abuse and Alcoholism (NIAAA), often discusses how alcohol affects the brain's reward system. When you remove the substance, the brain demands a substitute to maintain its "set point" of pleasure. Often, that substitute is highly palatable, calorie-dense carbohydrates. If you swapped 500 calories of vodka for 600 calories of evening snacks, the scale stays stuck.

Metabolic Adaptation and the "Healing" Phase
Your liver has been busy. For years, perhaps, it prioritized processing ethanol—a toxin—over performing its other 500+ functions, including fat metabolism. When you stop, the liver doesn't just immediately become a fat-burning furnace. It has to heal.
Six months is a significant milestone, but in the context of long-term metabolic health, it's still early days.
There is also the "pink cloud" effect followed by a metabolic plateau. In the first few weeks, you might lose water weight because alcohol is an inflammatory diuretic. But once that initial flush is over, your body enters a state of homeostasis. It’s trying to figure out its new "normal." If you have underlying insulin resistance—which many long-term drinkers do—your body might still be struggling to access stored body fat for fuel, even without the alcohol interference.
The Cortisol and Sleep Paradox
Here is something weird: sometimes we don't lose weight because we are trying too hard.
Quitting drinking is a massive stressor on the nervous system. Even if you feel "calm," your internal chemistry is recalibrating. High cortisol (the stress hormone) is a notorious weight-loss killer, specifically causing the body to hold onto visceral fat around the midsection.
Then there’s the sleep. You’d think 180 days of sober sleep would make you a super-athlete. But for many, the first six months are plagued by "rebound insomnia" or disrupted REM cycles. According to research published in Alcoholism: Clinical and Experimental Research, sleep architecture can take up to a year to fully normalize after chronic alcohol use. If you aren't sleeping well, your ghrelin (hunger hormone) goes up and your leptin (satiety hormone) goes down. You end up eating more during the day just to stay awake, effectively neutralizing the calorie deficit created by sobriety.

You're Gaining Something Other Than Fat
We need to talk about body composition.
Stop looking at the number. Seriously.
Alcohol is catabolic, meaning it actively breaks down muscle tissue by inhibiting protein synthesis. When you stop drinking and (presumably) start moving a bit more or even just eating better protein, your body begins to repair muscle. Muscle is significantly denser than fat.
It is entirely possible to go 6 months no alcohol and no weight loss while simultaneously dropping two pants sizes. Have you measured your waist? How do your shirts fit across the shoulders? If you are "recomposing"—losing fat while gaining muscle—the scale will lie to your face every single morning.
The "Health Halo" Trap
There’s this psychological phenomenon where, because we are doing one "virtuous" thing (not drinking), we give ourselves a pass on everything else.
"I didn't drink today, so I deserve this extra large pasta."
"I'm sober, so I can skip the gym."

This is the Health Halo. It’s a subconscious negotiation. You might be moving less than you think. Alcohol often provides a weird, frenetic energy or accompanies social activities that involve standing and moving. If your sobriety has turned you into a homebody who binge-watches Netflix until 11 PM, your Total Daily Energy Expenditure (TDEE) might have plummeted.
Hidden Liquid Calories
So you swapped the Gin and Tonic for a "craft mocktail."
Check the label.
Many non-alcoholic replacements are loaded with simple syrups, agave, and fruit juices to mimic the "mouthfeel" of spirits. Some of these mocktails have more sugar and calories than the original drink. If you’re hitting the seedlip-and-tonics or the booze-free beers hard, you might still be drinking your "dessert" every night.
Actionable Steps to Break the Plateau
If you are at the six-month mark and feel stuck, it’s time to move past "just not drinking" and start "active recovery" for your metabolism.
- Track your data for exactly seven days. Use an app like Cronometer. Don't change how you eat; just record it. Most people are shocked to find they are eating 300–500 more calories in snacks than they realized.
- Prioritize protein like your life depends on it. Aim for 1 gram of protein per pound of goal body weight. This increases thermogenesis (the energy required to digest food) and kills the sugar cravings that alcohol withdrawal leaves behind.
- Get a blood panel. Specifically, ask for Fasting Insulin, HbA1c, and a full Thyroid panel. Alcohol can mask underlying issues like hypothyroidism or bridge the gap into Type 2 diabetes. You need to know if the "engine" is actually working.
- Move, don't just "exercise." Don't worry about hitting the gym for an hour of soul-crushing cardio. Focus on 10,000 steps. Walking lowers cortisol, whereas high-intensity interval training (HIIT) can sometimes spike it, keeping that stubborn "alcohol belly" (which is now just a "stress belly") right where it is.
- Audit your "sober" drinks. Switch to plain sparkling water with a squeeze of fresh lime. Avoid the sodas and the high-sugar kombuchas for a month.
Six months is a massive achievement. Don't let a static number on a plastic square in your bathroom diminish the fact that your organs are functioning better than they have in years. The weight loss often follows the internal healing—it just operates on a delay.
The next step is to look at your daily movement patterns. If your sobriety has become sedentary, start by adding a 20-minute walk after your largest meal to blunt the glucose spike and signal to your body that it’s time to start burning stored energy again.
