I Tested Alcohol Again — On Purpose. 8 lbs of Water and 7 Days of Inflammation Later.

July 10, 2026 | Ben Nelson, Founder of ShredCoach

Back in May, I wrote about what happened when two cocktails and some appetizers on Cinco de Mayo spiked my weight 3 lbs in 48 hours after 70 days of eating clean. I ended that post saying I was done with alcohol for good.

Then the scientist in me started nagging. One data point isn't proof. Maybe Cinco was a fluke — the wheat, the dairy, the tomatoes, all hitting at once. Maybe alcohol alone wasn't the problem.

So two weeks ago, in Las Vegas, I ran the experiment again. Deliberately, this time.

The Setup

This wasn't a relapse dressed up as science. I planned it like a test, because after the Cinco post, readers kept asking me the same question: was it the alcohol, or was it the food?

Going into that Vegas weekend I was deep into the cut — around day 115 of 130, weight trending steadily down, inflammation long gone, sleep and energy the best they'd been all year. On June 24, two days before the trip, the scale read 194.0 lbs. A clean baseline.

The test: drink over a weekend in Vegas, keep everything else as controlled as a Vegas trip allows, and let the scale and the data tell the story.

What Happened: The Full Timeline

Days 1-2 — the spike. The morning after, the scale jumped hard. By June 29 I'd gone from 194 to 202. Eight pounds. After Cinco it was 3. This time my body escalated the response.

Days 3-4 — the plateau. This is the part that breaks people. Back home, eating perfectly clean, hydrating, walking — and the scale barely moved. The water wasn't leaving yet. My rings were tight, my face was puffy, my joints felt stiff.

Days 5-6 — the drain begins. The whoosh started. Down 2, then 3 lbs across two mornings as the inflammatory water finally started releasing.

Day 7 — baseline. A full week after the weekend, the scale read 194 — exactly where it started. Not 194-ish. 194. Seven days of progress, paused, for one weekend of drinks.

Today, July 10 — below baseline. This morning the scale read 192.3. Once the inflammatory water finished draining, the cut picked up right where it left off — through the old baseline and past it, like the weekend never happened.

That 192.3 is the whole argument in one data point. If any meaningful part of the 8 lbs had been fat, I couldn't be below my pre-Vegas weight two weeks later on a normal deficit. The math agrees — you'd need to overeat by roughly 28,000 calories to gain 8 lbs of actual fat, and nobody does that in a weekend, not even in Vegas. It was water, held by an immune system that clearly no longer tolerates alcohol.

Why the Second Reaction Was Worse

Cinco de Mayo: 3 lbs, gone in about 4 days. Vegas: 8 lbs, gone in 7. Same body, cleaner baseline, bigger response.

That tracks with how sensitivities work. When you eliminate an inflammatory trigger for months, your body doesn't become more tolerant of it — it often becomes louder about it. The chronic exposure that used to mute the reaction is gone, so when the trigger comes back, the response is sharper and easier to measure.

There's also a compounding factor I'll own honestly: Vegas is an inflammation stress test all by itself. Restaurant food is saltier than anything you'd cook. Sleep is worse. You're flying. Even a teetotaler comes home from Vegas holding water. But an 8-lb spike that takes a full week to clear isn't salt and jet lag — that's a systemic response.

Does the Dose Matter? (Full Disclosure: This Was Not Two Drinks)

Time to be completely honest about the size of this experiment, because it changes how you should read it. This wasn't a couple of cocktails. This was two days of drinking in a row, and on Saturday alone I had probably north of 16 shots of tequila across drinks mixed with soda water and pineapple. Cinco de Mayo was a few drinks with dinner. Vegas was a different order of magnitude.

So the natural question — the one I asked myself on the flight home — is whether the dose is what made the reaction so much worse. Would two drinks have done the same thing to me as sixteen? The physiology says almost certainly not:

• The response scales, but not in a straight line. At a few drinks, your liver processes the alcohol's toxic intermediate (acetaldehyde) roughly as fast as it arrives. At 16 shots, it can't keep up — the toxin circulates for hours longer and inflames far more tissue. • Heavy doses unlock effects light doses don't. High-volume drinking temporarily makes the gut lining more permeable, letting things into the bloodstream that trigger a much larger immune response. That mechanism mostly doesn't fire at one or two drinks. • Dehydration rebound. Sixteen shots dehydrates you severely, and your body answers by aggressively hoarding water for days. Two drinks barely registers on that system. • Day two stacked on day one. Drinking two days in a row means the second day's inflammation lands on top of the first's, before any recovery has happened.

What the dose question doesn't change: months of abstinence didn't make my body more fragile. There's no evidence your system "punishes" you extra for drinking after a break — the escalation from 3 lbs to 8 lbs is far better explained by a few drinks versus sixteen than by lost tolerance.

And here's the honest gap in my data: both of my experiments were meaningful doses. I have zero measurements on what two drinks does to my body now. Maybe it's a 1-lb blip that clears in two days. Maybe my threshold is low enough that even two drinks costs me several. That's a third experiment — a controlled, two-drink test on a clean baseline — and if I ever run it, you'll get the data here.

What the Data Bought Me

Watching that 8 lbs sit there for days, I felt none of the panic I would have felt two years ago — because the app told me exactly what was happening. My logged calories couldn't mathematically support fat gain. The trend line was flat under the spike. It was water, and water leaves.

This is the entire reason I track. Not to be perfect — I clearly wasn't — but so that when the scale does something scary, I have data instead of dread.

And this is where most cuts die. Someone has a big weekend, sees +8 on the scale, concludes the diet "isn't working," and quits — two weeks before the water would have cleared and revealed they were fine the whole time.

The Verdict

Two controlled tests. Two escalating reactions. The question I set out to answer — alcohol or food? — has its answer: for my body, alcohol alone is enough. The inflammation cost is real, measurable, and getting more expensive each time.

So now I can say it with data instead of drama: I'm done with alcohol. Not because a wellness influencer told me to quit. Because I ran the experiment twice and the results replicated.

If You Want to Run Your Own Test

You don't have to take my word for any of this — that's the point. Your triggers are yours. Here's the protocol:

1. Get a clean baseline. At least 3-4 weeks eliminated, weight trending predictably. 2. Reintroduce one variable. Just the alcohol. Or just the wheat. Not everything at once, or you'll learn nothing. 3. Track everything through the spike. Daily weigh-ins, same time, same conditions. Log every meal — this is exactly what quick logging in ShredCoach is for. 4. Wait for the trend line to answer. Give it a full week minimum before drawing conclusions. Water lies for days; the trend tells the truth.

The scale spike after a big weekend has broken more cuts than any birthday cake ever has. Understand what the number is actually telling you, and it loses its power to make you quit.
