How to Stay Slim: A Mustachian Guide to Health and Fitness


If Mustachianism could be summed up in one word, it would be control.

Most people arrive at this philosophy feeling overwhelmed by a lifetime of surrendering to the storms of unchecked consumerism. They feel their happiness, wealth, and even health are dictated by external forces—politicians, corporations, or economic circumstances. And to some extent, they’re right. The modern world is designed to subtly and pleasantly trap you in a cycle of working, spending, and borrowing, leaving little room for autonomy.

When you embrace Mustachianism, you begin to regain control. You see the excesses of your previous lifestyle and start carving a path to financial independence. But this journey isn’t just about cutting costs—it’s about reshaping your desires and embracing a new way of life, one that brings happiness while requiring less.

At its core, Mustachianism is about learning to control your own mind. Once you grasp this, you can apply it beyond finances—breaking destructive habits like smoking, binge-watching TV, or overeating. Physical fitness, much like financial independence, is a matter of control. And because I care about your well-being, I want to ensure you’re not just wealthy but healthy too.


The Keys to Slimness

Physical fitness might seem unrelated to financial freedom, but both hinge on self-control. A lack of it often leads to poor decisions about food and exercise. Here’s how to reclaim that control and, with it, your health.

1. Understand the Problem

Research reveals two major reasons for the rise in obesity:

  • Lack of knowledge: Many people genuinely don’t understand what constitutes a healthy diet and lifestyle.
  • Psychological challenges: Even when people know better, they struggle to resist unhealthy habits.

For example, many think it’s fine to drink sugary sodas or consider walking to their car sufficient exercise. Others fall into patterns of binge eating or skipping workouts due to stress or convenience.


Practical Steps to Slimness

Watch BBC’s “The Truth About Food: How to Be Slim”

This fascinating documentary uses real experiments to debunk common myths about weight loss. Here are a few key takeaways:

  • “I’m fat because I have a slow metabolism”
    Not true. Heavier individuals typically have faster metabolisms because their bodies work harder to maintain extra tissue. The real issue is overeating, often driven by unrecognized hunger signals. A simple solution? Eat more protein and cut back on bread.
  • “All calories are fully digested”
    Not necessarily. Foods high in calcium can reduce fat absorption. In the documentary, participants who ate low-fat yogurt excreted more undigested fat compared to others.
  • Portion size matters
    Larger portions lead to overeating. People who are served double portions tend to consume 45% more food without realizing it.
  • Keep a food diary
    Tracking what you eat makes you more mindful of your choices. A quick photo of your meals can deter mindless snacking and help you stay on track.

Tips from the Mustachian Playbook

Learn to Appreciate Hunger

Mild hunger can be invigorating. Instead of rushing to eat at the first sign of hunger, view it as your body tapping into stored fat reserves. Snack smartly with vegetables like cucumbers or carrots to keep your nutrient intake up without overindulging.

Incorporate Weightlifting

Strength training is one of the most efficient ways to lose fat. Building muscle requires significant calories, and beginners can trigger substantial muscle growth with just a few intense workouts. Exercises like squats, bench presses, and rows can transform your body faster than hours on a treadmill.

Rethink Your Breakfast

Switch from sugary cereals and toast to high-protein options like eggs, almonds, or cheese. These meals curb hunger and reduce the temptation to snack before lunch.


Control Is Key

Becoming slim isn’t about starvation or extreme diets—it’s about mental control. By learning to manage your mind, you can build healthy habits that stick.

If you stumble along the way, don’t beat yourself up. Recognize that the challenge lies in your mindset and keep working to strengthen it.
