Outrun the Treadmill Mentality: Why Fat Loss Isn't About Working Out

Mike Collette • May 30, 2025

If You're Still Relying on Exercise to Lose Weight… You're Going to Lose

Spoiler alert: Exercise alone is not a winning weight loss strategy. In fact, if it’s your only lever, you’re likely setting yourself up to fail — not because movement doesn’t matter, but because it’s only one part of a much bigger metabolic equation.

Let’s clear this up with real numbers, not noise.

How Your Body Actually Burns Calories

Your Total Daily Energy Expenditure (TDEE) — or the number of calories you burn each day — comes from four main sources:

📚 Sources:

Levine JA. Non-exercise activity thermogenesis (NEAT). Best Pract Res Clin Endocrinol Metab. 2002;16(4):679–702.

Hall KD et al. Quantification of the effect of energy imbalance on bodyweight. Lancet. 2011;378(9793):826–837.


Why You Can’t Out-Train a Poor Diet

Even a “great” workout — say, 45 minutes of high-intensity training — might burn 300–500 calories. That’s about the same as:


  • 1 muffin and a flavored latte
  • 1 Chipotle burrito
  • Or just… overeating slightly all weekend


And research backs this up:


A 2009 study from Louisiana State University followed women exercising 3–5x/week for 6 months. Result: negligible fat loss unless diet was also changed.


A 2012 meta-analysis in Obesity Reviews concluded that “exercise alone produces modest weight loss,” especially without dietary control.


So What’s the Point of Training Then?


Because exercise is your metabolic amplifier, not your calorie eraser.


Here’s what smart strength training and aerobic work actually do:


1. Builds Lean Muscle → Boosts BMR

Muscle is metabolically active. That means it takes more energy just to maintain it. Studies show that increasing muscle mass raises resting energy expenditure (BMR), even when you're doing nothing.

2. Improves Insulin Sensitivity


This makes your body more efficient at using carbs for fuel instead of storing them as fat.


📚 Source: Holten MK et al. Improved insulin sensitivity after physical training in insulin-resistant individuals. Diabetes. 2004;53(2):294–305.


3. Enhances Hormonal Balance


Exercise (especially strength work and zone 2 aerobic training) helps regulate:


  • Cortisol (stress hormone, linked to belly fat)
  • Leptin and Ghrelin (hunger/fullness hormones)
  • Testosterone and Growth Hormone (preserve/build muscle)


4. Improves Sleep


Quality sleep increases leptin, reduces ghrelin, and improves dietary adherence.


📚 Source: Spiegel K et al. Sleep curtailment increases hunger and appetite. Ann Intern Med. 2004;141(11):846–850.


Training Is Like Investing in the Stock Market

Think of each workout like a deposit — not an instant return.


“You don’t make money just because you bought stocks today. But over time, with consistency, the dividends compound.”


In the same way:


  • A single workout burns 200-300 calories


  • But 3 months of lifting + recovery = 5–10 lbs of added muscle


  • That muscle burns more calories every day, even at rest


And unlike cardio alone, strength training helps preserve muscle while in a caloric deficit — preventing the other outcome of losing body fat AND muscle. Just remember... more muscle, the more you burn.

The Real Fat Loss Formula: Nutrition + NEAT + Training + Sleep


Let’s simplify:

If You Remember One Thing…


Don’t chase sweat — chase systems.


  • Stop thinking of exercise as a punishment for eating.


  • Stop thinking you can eat whatever you want because you worked out.


  • Stop tracking your Fitbit burn like it’s gospel.


  • Start training to be stronger, not just lighter.


Your weight loss strategy should start in the kitchen — but it ends in how your body adapts to smarter inputs.

Devon is a fantastic part of our community — always kind, coachable, easy-going, and consistently putting in the work. She shows up, supports others, and truly represents what PTS is all about. Prototype of the Month is well deserved! Below, she answers a few questions about her time at PTS. 1.) Share your experience at Prototype After what felt like an entire year of sitting during grad school, I knew I wanted to be more active. I came back to Prototype, and it was the best decision. I’ve made so many new friends here who make every class fun (no matter how tough the workout is) but my favorite moment has to be meeting my boyfriend Ed! 2.) What is your favorite part about being at Prototype? I used to do at-home workouts and always felt like something was missing. When I came to Prototype, it felt like I finally found that missing piece, the community! It truly makes a huge impact. Everyone here genuinely wants the best for you. 3.) What are your hobbies and activities? If I’m outside, I love playing pickleball, skiing, and going for walks. And if I'm inside I enjoy crocheting, reading, or baking! 4.) How has Prototype helped you or solved a problem for you? Prototype has shown me that if you put your mind to something, you can truly do hard things. I also know I will always feel better after going to the gym. Sometimes the hardest part is just getting in the car, but I never regret it once I’m there. 5.) What are you continuing fitness goals to this point? To get some form of movement everyday and to one day get a pull up. 6.)

Tim has been an incredible part of our community — always positive, funny, generous, and willing to help. His energy makes everyone around him better. Prototype of the Month is well deserved! Below he answers some questions about his time at PTS. 1.) Share your experience at Prototype This actually isn’t my first stint at Prototype - I’ve been around and worked out here a few times in my heyday. My very first legitimate class though, as a member, was 5am earlier this year and I was welcomed first by Nicole. You can all imagine how that interaction went… and I came back! Prototype is welcoming, fun, clean, and I’ve made amazing friends along the way. It is one of the best hours of my day. 2.) What is your favorite part about being at Prototype? Prototype is not just another workout but a mental reset for me, it fills my cup. 3.) What are your hobbies and activities? Activities mostly involve time with my family outside whenever we can, trips to Ptown and traveling all over for work. I have a hard time sitting still and typically keep a busy schedule. Mix in photography and interior design opportunities with fitness and family and I’d say that's my perfect mix. 4.) How has Prototype helped you or solved a problem for you? I work remotely so in person face to face conversation is something I’ve found I need for my mental health. I’m also super competitive so I tend to push a little harder when I workout with others. 5.) What are you continuing fitness goals to this point? I want to be a parent who can show up for their kids in every aspect of life, which also means physically. Staying fit is important to be able to keep up with them as we collectively get older. I am training for a few Hyrox races coming up but mostly just trying to maintain my current level of fitness for as long as possible. 6.)
