Why ‘Eat Less, Move More’ is the Worst Weight Loss Advice Ever

If you’ve ever struggled with your weight, chances are you’ve been told some version of this classic advice: “Just eat less and move more.”

Sounds simple, right? So why doesn’t it work?

For decades, we’ve been sold the idea that weight loss is just about willpower and discipline. Cut calories, exercise more, and the kilos should drop. But anyone who has attempted to lose weight can tell you – it’s not that easy.

So why do we struggle?

The truth is, weight loss is about so much more than just calories in versus calories out. 

Why Our Bodies Hold Onto Fat

If we look at history, holding onto fat made perfect sense. Our ancestors didn’t have access to three meals a day, let alone snacks, protein bars, and Uber Eats. Food scarcity was real, and the body evolved to store fat as an energy reserve for times of famine/starvation.

Even today, our bodies still function as if we might face starvation at any moment. When we dramatically cut calories, the body responds by slowing down metabolism, increasing hunger hormones, and making weight loss harder—not easier. This is not a failure of willpower; it’s your body doing what it was designed to do. 

The Real Problem: Your Metabolism is Not a Simple Math Equation

Your body isn’t a machine that simply burns calories based on what you eat and how much you move. It’s a complex system regulated by hormones, metabolism, and even your gut health—all of which influence how your body stores and burns fat.

 Insulin resistance: When your body becomes resistant to insulin, it holds onto fat more easily, making weight loss harder—even if you’re eating less.

Hormones matter: Leptin (the hormone that tells you when you’re full) and ghrelin (the hormone that makes you feel hungry) can be completely out of balance in people struggling with weight.

Set point theory: Your body fights to maintain a certain weight range, slowing metabolism and increasing hunger signals when you lose weight to try to “protect” itself and save it’s high energy fat for tougher times.

What You Can Do to Lose Weight

Sustainable weight loss isn’t about starving yourself or punishing workouts. It’s about working with your body, not against it. 

Here are some less obvious but highly effective strategies that many people overlook:

  1. Prioritize Sleep – Poor sleep disrupts ghrelin (hunger hormone) and leptin (fullness hormone), making you crave high-calorie foods. Aim for at least 7-9 hours of quality sleep each night.
  2. Manage Stress Effectively – Chronic stress elevates cortisol levels, leading to fat storage, especially around the abdomen. Techniques like meditation, deep breathing, and walking outdoors can significantly help.
  3. Eat More Protein (But Not Just for Muscle Growth) – Protein reduces cravings, stabilizes blood sugar, and increases thermogenesis (the calories burned digesting food). Try to get at least 1.6-2.2g of protein per kg of body weight daily.
  4. Incorporate NEAT (Non-Exercise Activity Thermogenesis) – Small movements throughout the day (like standing more, fidgeting, or walking while talking on the phone) burn far more calories than you think and contribute to long-term weight loss.
  5. Time Your Meals Strategically – Eating protein-rich meals earlier in the day helps regulate hunger hormones and keeps blood sugar stable, reducing the likelihood of evening binges.
  6. Use Resistance Training Over Endless Cardio – Strength training builds lean muscle, which increases your resting metabolism and allows your body to burn more calories even at rest.
  7. Drink More Water (Especially Before Meals) – Hydration reduces hunger signals, prevents unnecessary snacking, and can increase metabolism by 10-30% for about an hour after drinking.
  8. Optimize Your Gut Health – A diverse gut microbiome can improve digestion and help regulate fat storage and cravings. Eating fermented foods and fibre-rich plants supports healthy gut bacteria.

When Medication Might be Necessary

Despite doing everything right—eating well, exercising, sleeping properly—some people still find themselves stuck at a certain weight. This is not a failure of willpower! It’s because their body’s set point is keeping them there.

Just like some people fail conservative therapy for high cholesterol, blood pressure, or blood sugar and need medical treatment, some people need weight loss medication to break through their set point and recalibrate their body to a healthier weight.
