Why I Started This Blog: I'm a Dietitian Who's Tired of Watching You Get Scammed by Diets and Workout Fads

I’m Erin Gallagher. I’m a registered dietitian in Boston. I’ve been doing this work for twenty years—eight of them on hospital floors, twelve in outpatient weight management, and the last several running my own telehealth practice. I’ve worked with more than four thousand people on fat loss and metabolic health.

And I’m tired.

I’m tired of watching smart, hardworking adults get sold the same shiny lie over and over: that fat loss has to be dramatic, complicated, or extreme to “work.” I’m tired of the diet industry and the fitness industry taking turns promising you a faster, easier, more exciting version of results that never stick. I’m tired of seeing people regain every pound—and then blame themselves for “not having enough willpower.”

So I started this blog.

The same cycle, different packaging

Here’s the pattern I see almost every week.

Someone comes to me after their third or fourth diet. They’ve done keto. They’ve done intermittent fasting. They’ve done the 30-day transformation program that promised six-pack abs and a “complete body reset.” They’ve bought the detox tea, the fat-burning supplement, the meal-replacement shakes, the app that counts every micronutrient. They’ve followed the Instagram coach who told them cardio was the secret, then the next one who said lifting heavy was the only way, then the one who said they needed to “tone up” with resistance bands and pink dumbbells.

They lost weight. Sometimes a lot of it. Then life happened—work stress, a kid’s schedule, a vacation, a plateau—and the weight came back. Often with interest.

When they sit down with me, the first thing many of them say is some version of: “I just need more discipline.”

No. You don’t.

You were sold a product designed to fail long-term so you’d buy the next one.

Crash diets create rapid weight loss by tanking your calories and often your protein. Your body responds the way bodies have responded for millennia: it slows things down, holds onto energy, and makes you hungrier. Workout fads do the same thing on the training side—promising “spot reduction,” “toning,” or “fat-blasting” circuits that look impressive in a 45-second Reel but don’t build the muscle or the recovery capacity that actually supports fat loss over years.

The result is the same: temporary change, permanent frustration, and a growing belief that you are the problem.

You’re not.

What actually moves the needle (it’s boring)

After two decades of watching what works and what doesn’t, here’s the unglamorous truth I tell every new client:

Fat loss is mostly math and habits.

You need a moderate calorie deficit that you can sustain. You need enough protein so you don’t lose muscle while the scale moves. You need strength training that builds or at least preserves muscle, because muscle is metabolically expensive tissue and it makes the body you end up with look and function better. You need to sleep enough and manage stress well enough that your hormones don’t fight you every step of the way. And you need to do all of this in a way that still lets you live a normal life on a Tuesday in March when the kids are sick and the weather is terrible.

That’s it.

No magic food. No forbidden food group. No 6 a.m. bootcamp that leaves you wrecked for the rest of the day. No 1,200-calorie “reset” that leaves you ravenous and thinking about food constantly.

The people who keep the weight off aren’t the ones who found the perfect diet or the perfect workout. They’re the ones who stopped looking for perfect and started building something repeatable.

Eat enough. Train hard. Repeat.

Why both sides of the equation matter

Most fat-loss advice treats food and training like separate religions. The diet camps act like exercise is optional. The fitness camps act like you can out-train a terrible diet. Both are wrong.

Nutrition without training often produces a smaller version of the same body—less muscle, lower metabolic rate, easier regain. Training without adequate fuel produces burnout, stalled progress, and the classic “I’m working out six days a week and the scale won’t move” frustration.

I cover both because they belong together. I’m a dietitian by training and credential, but I’ve spent enough years watching clients lift, plateau, and succeed to know that strength training is one of the highest-leverage tools we have for sustainable fat loss—especially for people over 30, and especially for women who’ve been told for decades that they should only do light weights or endless cardio.

I’ll give you the numbers. I’ll show you how to build a plate without an app if you don’t want one. I’ll explain why the five basic lifts cover most of what you need. And when something is outside my lane—advanced programming, injury rehab, medical nutrition therapy for complex conditions—I’ll say so and point you toward the right professional.

A little about the person behind the keyboard

I’m 48. I live in the Boston area with my husband Kevin (high-school chemistry teacher, official garden pH adjuster) and our two kids—Molly, who’s a sophomore at UMass Amherst, and Finn, who’s in seventh grade. When I’m not in client sessions I spend a lot of time in my vegetable garden and hiking the White Mountains in New Hampshire. I weigh my oatmeal most mornings—not because I’m dieting, but because I’m a nerd and it takes twenty seconds.

I’ve seen enough cycles of hope and disappointment to know that the boring approach is the one that actually lasts. That’s why this site exists.

If you’re done getting scammed by the next diet or the next workout fad, you’re in the right place.

We’ll keep it simple.
We’ll keep it honest.
And we’ll keep showing up.

Eat enough. Train hard. Repeat.
