I wasn't sitting on the couch. I walked every night after work. I lifted three days a week. I ordered the grilled chicken at every birthday dinner while everybody else got the burger. I spent over $300 on green powders and a ten-day cleanse.

And yeah, I drink. A few beers most nights, more on game day. I wasn't quitting, so I figured the belly was just the price.

On the first of every month, I took a picture in the bathroom mirror. After two years I had twenty-four of them. Put the first one next to the last one and you can't tell which is which.

Picture #1 and picture #24. Two years apart.

My belly stuck out over my belt on skinny arms and legs. I was bloated after dinner, with a dull pressure under my right ribs. By 2 p.m. I was reading the same email three times. Then my blood work came back with my liver numbers a little high. My doctor pressed under my right ribs and said, "Let's keep an eye on it."

That was the whole plan. Wait and see.

Walt. Seventy-one, one cold beer on the porch every day at four, and flatter than I was at thirty.

Walt lives next door. He's 71, he still mows his own lawn, and every afternoon at four he sits on his porch with one cold beer. He's flat as a board.

One night I was dragging the trash cans to the curb after my walk, and he called me over.

"You walk past this porch every night," he said. "How long you been at it?"

"Two years."

"And it ain't moved."

"Not an inch."

He took a sip of his beer. "You ain't lazy. Lazy guys don't walk past my porch every night for two years."

Then he asked me five questions, the same five you just answered. I said yes to all five.

"That's not a lazy belly," he said. "That's a liver belly."

1. Your liver handles the fat. It decides what gets burned for energy and what gets stored.

2. Alcohol cuts the line. Your liver treats alcohol like poison, so it clears that first. Everything else waits, fat burning included.

3. Do that most nights for years, and the fat parks in the liver itself. A fatty liver falls behind, so what you're trying to burn off just sits there. It also falls behind on clearing estrogen, and that parks on your belly and chest too.

4. That's why the belly won't move, no matter what you do. Arms and legs skinny, belly out front. That was me in all twenty-four pictures. Powders, cleanses and heavier weights never touch the liver. That's why nothing I tried worked.

Why the belly stays put, the way Walt explained it.

Here's what my doctor didn't say. Fat on the liver is where it starts. Keep feeding it, and in some men it turns into inflammation, then scar tissue. Among heavy drinkers, up to 1 in 3 get liver inflammation and up to 15 in 100 end up with cirrhosis.[2]

You don't feel most of it. A little bloat, a dull pressure under the ribs, a 2 p.m. crash. That's about as loud as it gets.

Waiting isn't a plan. I was done waiting.

I told Walt I'd tried milk thistle. A big thousand-milligram bottle from the drugstore, a year in my cabinet.

"Go home and find out how much silymarin is in it," he said. "That's the part that does the work."

I looked. A thousand milligrams on the front, and nowhere on the bottle did it say how much silymarin was inside. One ingredient, and no idea how much of the part that works.

My old bottle next to Walt's.

Walt's comes with a 90-day money-back guarantee, even if the bottle's empty. So I had nothing to lose.

Every morning with my coffee. That's the whole routine.

Walt's is called Enerra Milk Thistle. It has 240 milligrams of silymarin in every capsule, plus five more things working with it:

• Milk thistle, 300 mg at 80% silymarin. That's the 240 mg. Silymarin is the part of milk thistle researchers actually measure.
• Inositol, 200 mg. Helps your liver move fat out instead of storing it.
• Kudzu root (pueraria). Drinkers in China have used it for centuries.
• Turmeric, vitamin C and L-methionine, in smaller amounts.

I asked him what every guy asks. "Walt, I've spent two years and a closet full of powders on this. Why would a capsule do what all that didn't?"

"Because none of that was for your liver," he said. "This is."

He stood up off the porch chair.

"I'm 71. I have a beer every day, and I take that every morning. You see a belly on me?"

I took it every morning and changed nothing else.

Week 1. Honestly, not much. Walt had warned me: "This is the week guys quit. Don't."

Day 10. My face looked less puffy in the mirror. I looked twice.

Week 2. No 2 p.m. crash. No bloat after dinner.

Day 30. I took picture number twenty-five and put it next to number twenty-four. For the first time in two years, they didn't match.

The first two months.

Not a six-pack. A smaller belly, a thinner face and a shirt that fit. After twenty-four pictures that never moved, that was everything.

That's why I tell every guy the same thing: don't buy one bottle. My real picture came at month two. The guys who quit in week one never find out.

Walt and I aren't the only ones. Here's what three other customers wrote, two on Enerra's own page and one on Amazon.

Liam B., 52, verified customer: "Three months on this. Haven't quit drinking. Still have my beers. But my body handles it completely differently now. The morning puffiness is gone. The afternoon crash isn't a thing anymore."

Jessica M., verified customer: "Last year my bloodwork came back with elevated liver enzymes and my doctor said 'we need to keep an eye on this.' That scared me. ... I'm now 4 months in and just got my labs redone. My liver enzymes are NORMAL."

Bobby, verified purchase on Amazon: "I'm a few weeks in and I've really noticed a difference in my overall energy levels and digestion. This specific combination is the best that I've had and the capsules are easy to swallow!"

Nobody told me to quit. Walt still has his cold one at four. I still have my beers most nights, and a few more on game day.

I'm not telling you the beers are free. They're not, and Walt only has one. But I wasn't quitting, and "keep an eye on it" wasn't a plan. So I gave my liver some help.

Four o'clock on Walt's porch.

Her sister's barbecue. She made this one her phone background.

Two months in, my wife took a picture of me at her sister's barbecue. Shirt tucked in. Not sucking in. Not hiding behind anybody.

She didn't crop it. She made it the background on her phone.

I caught her looking at it at dinner. "What?" she said. "I like that one."

Tonight, pull your shirt up in the bathroom mirror and take a picture from the side. Don't study it. Put it in a folder.

Then find the pants that stopped buttoning and hang them on the closet door.

Take Enerra every morning. Change nothing else. Keep your beers.

On day 30, take the second picture and put on the pants.

The pictures decide. If they don't show you anything, you get your money back. It's a 90-day guarantee, even if the bottles are empty.

If you walk, lift, diet, do everything right, and that belly won't move, you're not doing anything wrong. You're working on the wrong thing.

You're not lazy. Your liver is clogged, and nothing you've tried touches it. Every month you wait is one more picture that looks exactly like the last one.

Right now it's Buy 2, Get 1 Free: three bottles for $54.99, about $18 a bottle. That's less than one night's bar tab. Get the three. My barbecue picture came at month two, and you're covered for 90 days, even on an empty bottle.

P.S. Walt asks every guy who stops at his porch the same thing: "You see a belly on me?" Take the picture tonight and let day 30 answer for you.
