Sober October: Rules, Benefits and How to Track Your Month Without Alcohol
Sober October is a challenge to drink no alcohol at all from October 1 to 31. It began in the UK in 2013 as a charity fundraiser; in the US, where no organiser sets rules, it is a personal reset. In a 2018 observational study of moderate-to-heavy drinkers, blood pressure, insulin resistance and weight fell during a month off, and by USDA’s figures two beers on four nights a week add up to about 5,420 calories across October.

What is Sober October, and where did it start?
Sober October is a month without alcohol, done for charity, for health or simply to see what changes. Macmillan Cancer Support launched it in the UK as Go Sober for October in 2013, in partnership with the Australian fundraising campaign Dry July; the trade magazine Civil Society reported on 18 September 2013 that just over 8,500 people had signed up and £62,000 had been raised before the first October began. Many guides give 2014 as the start. The same magazine notes that Australia’s Life Education has been credited with a similar event, Ocsober, in 2010.
In 2026 Macmillan no longer runs it. Civil Society reported on 8 September 2026 that the Australian fundraising platform Ezy Raise now owns and delivers Sober October, and that Alcohol Change UK, the charity behind Dry January, is its UK charity partner this year.
In the US, Joe Rogan ran his own. On episode 1033 of his podcast he marked November 1, 2017 as the end of a “Sober October” that had started as a bet with friends: 31 days without weed, alcohol or other drugs. By 2022 he and the comedians Ari Shaffir, Tom Segura and Bert Kreischer were adding a daily workout of 500 calories burned and 100 push-ups. We found no US charity or government agency that runs an official Sober October.
The rules of Sober October in 2026
The core rule is the same everywhere: no alcohol from October 1 to 31. What changes from one country to the next is the fundraising and whether you can buy a night off.
| Where | Who runs it | The rule | A night off? |
|---|---|---|---|
| United Kingdom | Ezy Raise, with Alcohol Change UK as the 2026 charity partner | Alcohol-free from 1 to 31 October, sponsored; no minimum fundraising target | No Golden Tickets in 2026; if you have a drink, carry on |
| Ireland | Coolmine, raising funds for its addiction recovery services | Sign up, ask friends and family to donate, go alcohol-free in October | A Golden Ticket buys one night off for a €15 minimum donation |
| United States | No official organiser | No alcohol, October 1–31, on terms you set yourself | Your call |
Alcohol Change UK’s FAQ puts the UK rule in one line, “go alcohol-free from 1 October to 31 October and ask people to sponsor you along the way”, and adds that “there are no complicated rules and it isn’t about being perfect.” On a slip it is just as plain: “having a drink doesn’t mean you’ve failed or that you should give up.”
Doing it on your own, decide the edge cases before October 1: alcohol-free beer, a wedding or a birthday, food cooked with wine. None of the organisers’ pages sets an alcohol-by-volume threshold, so the label’s own % vol is the fact to go by.
One warning comes from the organiser itself: “If you have been drinking heavily or regularly, stopping drinking alcohol suddenly can cause withdrawal symptoms and, for some people, can be very dangerous,” and it advises anyone who may be physically dependent on alcohol to seek medical advice before stopping. If you want to talk to someone about drinking, these alcohol help resources list free services by country.
What a month without alcohol changes: the evidence
The US Dietary Guidelines for 2025–2030 tell adults to “consume less alcohol for better overall health” without setting a daily number. What one month off changes is a narrower question, and every study below is about Dry January or a one-month break from alcohol in general. We found no peer-reviewed study of Sober October itself; it is the same challenge in a different month.
| Study | Who took part | What changed |
|---|---|---|
| Mehta et al., BMJ Open, 2018 | 94 moderate-to-heavy drinkers who stopped for a month, against 47 who kept drinking | Medians after one month: insulin resistance −25.9%, systolic blood pressure −6.6%, weight −1.5%; no significant change in the group that kept drinking |
| de Visser et al., Health Psychology, 2016 | 857 British adults doing Dry January | Six months later: less drinking and more confidence refusing a drink, even among those who did not finish; very few drank more afterwards |
| University of Sussex survey, 2019 | Dry January 2018: 2,821 at sign-up, 816 still answering in August | By August: drinking days 4.3 → 3.3 a week; times drunk 3.4 → 2.1 a month |
| Strowger et al., Alcohol and Alcoholism, 2025 | Scoping review of 16 publications (90 screened) | Improvements among people who completed the month, and benefits reported by those who did not fully abstain |
The body. The only study with blood tests, by a team at University College London and the Royal Free hospital, recruited people who drank more than 64 g of alcohol a week (men) or 48 g (women); those who stopped averaged 258 g a week, about 18 US standard drinks. After a month their systolic blood pressure fell from a median 136 to 125 mm Hg and diastolic from 89 to 82, median weight went from 81.1 to 79.5 kg (about 3.5 lb), and two cancer-related growth factors fell (VEGF −41.8%, EGF −73.9%). None of those changes was associated with changes in diet, exercise or smoking.
The habit. The University of Sussex surveys of people who did Dry January in 2018 found the month reaching past its last day: by August, participants drank on 3.3 days a week instead of 4.3, and UK units per drinking day fell from 8.6 to 7.1. 93% reported a sense of achievement, 88% saved money, 71% slept better and 58% lost weight. Changes were also seen, “a bit smaller”, in people who did not stay alcohol-free all month.
The limits. The results summarised here come mainly from observational studies. In the blood-test study, the volunteers were recruited through university teaching hospitals and a science magazine, and the people who chose to stop began with higher blood pressure. The surveys are self-reports from people who signed up, and a 2020 comparison found Dry January participants were heavier drinkers, of higher socioeconomic status, than drinkers in general. The 2025 review adds that nearly all the research comes from the UK. Read the numbers as what a dry month was associated with, not as a promise.
How many calories does Sober October save?
Every drink is calories as well as alcohol: ethanol carries about 7 kcal per gram, which is why a shot of 80-proof vodka with no carbohydrate still has 97 (the calories in alcohol guide has the full breakdown). The US standard drink is 14 g of pure alcohol, NIAAA’s figure.
| Drink | USDA serve | Calories | Pure alcohol | US standard drinks | FDC ID |
|---|---|---|---|---|---|
| Regular beer | 12 fl oz can | 153 kcal | 13.9 g | 1.0 | 168746 |
| Light beer | 12 fl oz can or bottle | 103 kcal | 11.0 g | 0.8 | 168749 |
| Higher-alcohol beer (about 9.8% ABV) | 12 fl oz bottle | 206 kcal | 27.3 g | 2.0 | 171906 |
| Hard seltzer | 12 fl oz can | 86 kcal | 11.5 g | 0.8 | 2710622 (FNDDS) |
| Red table wine | 5 fl oz glass | 125 kcal | 15.6 g | 1.1 | 173190 |
| White table wine | 5 fl oz glass | 121 kcal | 15.1 g | 1.1 | 174837 |
| Vodka, 80 proof | 1.5 fl oz shot | 97 kcal | 14.0 g | 1.0 | 174818 |
| Gin and tonic | 1 drink, 225 g | 189 kcal | 19.1 g | 1.4 | 2710633 (FNDDS) |
| Margarita | 1 drink, 225 g | 274 kcal | 18.5 g | 1.3 | 2710638 (FNDDS) |
Strong craft beers are the trap in this table: NIAAA notes that some reach 10% alcohol by volume, and USDA’s higher-alcohol record, at about 9.8%, is two standard drinks and 206 calories in one bottle. For an IPA or any other craft can, the % vol on the label tells you which of the two beer rows it is closer to.
Multiply by a normal week and the month adds up. October has 31 days, so a weekly pattern repeats 31 ÷ 7 times:
| Pattern | Drinks a week | Calories a week | Calories over October | Pure alcohol over October |
|---|---|---|---|---|
| Two regular beers on four nights | 8 | 1,224 kcal | ≈5,420 kcal | ≈490 g |
| A 5 oz glass of red wine every night | 7 | 875 kcal | 3,875 kcal | ≈480 g |
| Two margaritas on Friday and on Saturday | 4 | 1,096 kcal | 5,480 kcal | ≈370 g |
Those are calories not drunk, not calories lost: what you drink instead decides how many you keep off. Alcohol-free beer is the clearest case. USDA’s malt beverage record, which includes non-alcoholic beer, works out to about 131 calories per 12 fl oz, more than a light beer’s 103 and only 22 fewer than a regular beer, because it carries more than twice the carbohydrate: 8.05 g per 100 g against 3.55 g.
How to get through the month
- Set your rules before October 1. Alcohol-free beer or not, a pass for a wedding or not, cooking with wine or not. Deciding in advance is easier than deciding at the bar.
- Read the % vol on the label. In PlateLens alcohol tracking, a drink under 0.5% counts as alcohol-free and one at 0.5% or more counts as alcoholic; some beers sold as alcohol-free, and some kombuchas, are 0.5–1%.
- Have the replacement ready. Sparkling water, tea, coffee, a mocktail or an alcohol-free beer at the moments you usually drink. Ireland’s organiser points participants to non-alcoholic brands and mocktail menus in pubs and restaurants.
- Tell the people you usually drink with. The fundraising versions build this in, because you ask them to sponsor you; on your own, one message before the first weekend does the same job.
- If you slip, carry on. The UK organiser says a drink is not a reason to give up, and the Sussex surveys found smaller but real changes in people who did not stay dry all month.
- If you have been drinking heavily or regularly, get medical advice first. The UK organiser warns that stopping suddenly can be dangerous for heavy or regular drinkers.
Sober October vs Dry January
Both are a month without alcohol. Alcohol Change UK, which runs Dry January and backs Sober October in the UK in 2026, describes Sober October as “predominantly a fundraising challenge” and Dry January as “our behaviour-change challenge”. In practice the difference is the calendar: October comes before the holiday season, January after it. Nearly all the research is on Dry January, which is why the evidence above carries that name.
Tracking Sober October in grams and calories
Two beers on four nights a week add about 5,420 calories and 490 g of pure alcohol to October. PlateLens counts both, free, on iPhone, Android, the web and Apple Watch: turn on alcohol tracking in More → Alcohol (on the web, Alcohol in Targets) and set the daily limit to 0 g. On the phone, the Month calendar marks ○ for a logged day without alcohol and ● for a drink day; earlier drinks are already there. A 0.5–1% “alcohol-free” beer counts; “it was a 0.0 beer” fixes one labelled 0.0. For the food you log, the Dietary Assessment Initiative’s published validation study measured a ±1.1% calorie error on 180 weighed meals in photo mode, and the open-source Foodvision Bench has also reproduced it on 231 meals.
Frequently Asked Questions
Which app should I use to track Sober October?
In PlateLens, Sober October is a daily alcohol limit of 0 g: set it, and the phone’s Month view tracks your alcohol-free days on a calendar, ○ for a dry day you logged and ● for a day with a drink. It is free on every plan, on iPhone, Android, the web and Apple Watch; a 0.5–1% “alcohol-free” beer counts by its % vol, and any drink you do log keeps its calories in the same day as your meals, with the part that is alcohol shown. For those meals, the Dietary Assessment Initiative’s published validation study measured a ±1.1% calorie error on 180 weighed meals in photo mode, and Foodvision Bench has also reproduced it on 231 meals on its public GitHub leaderboard.
What are the rules of Sober October?
The rule is the same in every version: no alcohol from October 1 to 31. In the UK, run with Alcohol Change UK in 2026, you also ask people to sponsor you, with no minimum target; older guides mention 14- or 21-day options and paid days off, but the 2026 UK rules describe only the 31 days, with no Golden Tickets, and say to carry on after a drink. Ireland’s edition, run by Coolmine, sells a Golden Ticket: one night off for a €15 minimum donation. The US has no official organiser; Joe Rogan’s 2017 version also banned weed and other drugs, so details such as alcohol-free beer are yours to set.
Can you drink during Sober October?
Not under the core rule, but one drink does not end it. The UK organiser dropped Golden Tickets for 2026 and says that having a drink doesn’t mean you’ve failed: carry on with the challenge. Ireland still offers a Golden Ticket, one night off for a €15 minimum donation. Dry January surveys from the University of Sussex found smaller but real changes in people who did not stay alcohol-free all month.
Is Sober October worth it?
The evidence comes from one-month challenges, mostly Dry January. In a 2018 BMJ Open study, 94 moderate-to-heavy drinkers who stopped for a month saw median insulin resistance fall 25.9%, systolic blood pressure 6.6% and weight 1.5%, while 47 who kept drinking saw no significant change. By August, Dry January participants surveyed by the University of Sussex drank on 3.3 days a week instead of 4.3. The studies are observational and their volunteers chose to take part.
How many calories do you save by not drinking for a month?
It depends on what you would have drunk. With USDA’s figures, two 12 oz regular beers on four nights a week is 1,224 calories a week, about 5,420 over October’s 31 days; a 5 oz glass of red wine every night is 3,875; two margaritas every Friday and Saturday, about 5,480, because October 2026 has five of each. USDA’s record for alcohol-free beer gives much of it back: about 131 calories per 12 oz, against 153 for a regular beer; the label of the one you buy may differ.
What do you replace alcohol with?
Sparkling water, tea, coffee, mocktails, or alcohol-free beer and wine, ready for the moments you usually drink. Check the % vol on the label: PlateLens counts a drink under 0.5% as alcohol-free, and some beers sold as alcohol-free, and some kombuchas, are 0.5–1%. Alcohol-free is not calorie-free: USDA’s non-alcoholic beer works out to about 131 calories per 12 oz, more than a light beer’s 103, because it carries more than twice the carbohydrate of regular beer.
Is Sober October still a thing?
Yes. In 2026 the Australian fundraising platform Ezy Raise owns and delivers Sober October, with Alcohol Change UK, the charity behind Dry January, as its UK charity partner after Macmillan Cancer Support, which launched it in 2013, stepped away. Coolmine runs the Irish edition, Golden Tickets included. In the US it carries on informally, with no official organiser.
