About

Mind. Body. Back in Control.

Somewhere along the way, a lot of us lost a little control.

Not as sharp as we want to be. Not as lean, either.

We had it once. We want it back. And this time, we want to keep it.

I know because I’ve been there.

Why I Created BodyFitFast™

I’m Bob Rosenthal.

I created BodyFitFast for me.

Because I’d lost control myself and got it back.

I’d always been in pretty decent shape. Active, fit.

Then a few days before Thanksgiving, I broke my foot. No big deal, I thought. Then came a blood clot.

Out of commission for five, six months, healing. That’s when my mind allowed my body to get away from me.

That winter, on the couch a lot. Ate big. Packed on 15, 20 pounds. Pants didn’t fit. Felt lousy, sluggish, foggy…

New Year’s Eve dinner with my friend Patty. Took selfies on the couch. “Uh. You’re getting chunky, Bo. Skip dessert.” She kind of laughed and handed me the phone to see.

The pics hit me like a sucker punch.

My face looked distorted. I didn’t look like me.

New Year’s Day. A bloated stranger looked back at me from the full-length mirror.

Not gonna let my body go to hell and just settle for it. Not me.

I knew EXACTLY what to do (so I thought). Eat less, move more. I followed all the so-called expert advice.

Hours of brain-dead cardio on an exercise bike. Paleo. Keto. Counted calories. Hungry all the time. It sucked.

Six miserable months later, my foot was mostly healed. I was still fat.

Bob Rosenthal, shirtless and overweight, taking a selfie in a mirror — Damn. Bloated. Old. Stunned.

Conventional wisdom was wrong. Time for unconventional.

“Fasting” sure didn’t sound like fun. Yet, it seemed worth a shot.

So I built a fasting coaching program to coach myself.

Building it kept me focused and held me accountable. That allowed my mind to take charge again.

Took me a few days to adjust to the fasting. Sometimes I felt a bit hungry. A drink of water or black coffee, and it went away in a few minutes. After that, it was simple and easy. I actually enjoyed it.

And my body followed. It worked like gangbusters. The fat came off. All of it. And it stayed off for years.

The fog lifted. I was energized. I slept better. My clothes fit. I wasn’t embarrassed to take off my shirt.

I looked like me again. I felt like me again. So much more confident. So much more on.

It was just the greatest feeling, being back in control.

Friends noticed. “You look fantastic. What are you doing?”

Years later, that coaching program became Fast28, our first product.

Sound Mind. Sound Body. Ask Questions. Straight Answers.

Engraved bust of the Roman poet Juvenal — Juvenal wrote Sound Mind, Sound Body.

Engraved bust of the Greek philosopher Socrates — Socrates: the Socratic method.

Foggy and heavier at the same time? For me, it was one problem, not two.

The ancient Romans had an answer for that: “mens sana in corpore sano.”

It’s Latin for “a sound mind in a sound body.” The poet Juvenal wrote it nearly 2,000 years ago. A code to live by.

A sound mind and a sound body rise and fall together. Mine did.

And how do you get straight answers? Do what Socrates did. Keep asking questions until you get to the truth. Don’t put blind faith in authority.

Remember the food pyramid? The experts told us, “Fat bad. Carbs good.” How’d that work out?

The 1992 USDA Food Guide Pyramid, with bread, cereal, rice and pasta at the wide base — Expert Advice 1992.

Upside Down.

We question everything: the experts, the government, our teachers, the so-called influencers, the latest studies, the company line, and even our own ideas. So you get straight answers.

We test what we offer you with our own money. We go first.

Where to Start

Start with Fast28 coaching, our take on intermittent fasting. It’s a brand-new version of the program I first ran several years ago. The first group starts November 27.

The coaching comes to you every morning: a 5-minute video check-in, an email, texts and your Success Journal to keep you focused and accountable.

It’s designed for men who are off the GLP-1 shots, or tapering off, and don’t want the weight back. And for men who never took them and want to get leaner. No counting calories. No yo-yo diets.

We don’t have any ads, affiliate links or anything like that on the website. We’re proud American Capitalists. You can buy our coaching, and we’ll be using it ourselves. And the best-informed people make our best customers.

Round Two

Last March, I went all in on AI. Twelve hours a day at the screen. My life got crazy again, hectic, out of control. And then my mind allowed my body to get out of control.

I quit fasting. No gym. Junk food late into the night. Fifteen pounds came back.

Fasting kept it off. Quitting brought it back.

Hit bottom. Didn’t choose the shots.

I just decided to start again, getting my mind and then my body back in control.

And I’m rebuilding this coaching program to help other men with the same problem. Especially men coming off the shots.

Why sell it? Like I said, I’m a Capitalist.

I’ll be fasting with the men in the first group, coaching you and coaching myself at the same time.

First group starts November 27.

First-group price: $47, one time.

After the first group, it’s $67.

Unconditional money-back guarantee through all 28 days.
