Quality over quantity: A smarter way to lose weight

Why quality weight loss matters more than you think

For many people, stepping on the scale can feel like the defining moment in a weight loss journey. One number can seem to sum up all the effort, progress and setbacks.

Actors portrayal 

But weight loss is more complex than a single figure. Where there are many factors that define a healthy weight loss journey, losing the right kind of weight is arguably one of the most important ones. To understand what quality weight loss looks like we have to understand what the body is losing along the way: fat that can affect health, or the muscle that supports strength, movement and long-term wellbeing. This is where quality weight loss begins.

Up to 25-40% of weight loss can come from muscle or other fat free-mass if weight loss isn’t managed carefully.

Not all weight loss is equal. When you lose weight you don’t just lose fat, you can lose muscle too. Understanding your body composition, can help you to focus your weight loss goals to achieve fat loss and muscle preservation.

So, what is your body made of, and why does this matter when managing your weight and health? 


ComponentWhat it isWhy it matters
Fat massAll the fat in your body, including visceral fatReducing excess fat can lower risk of cardiovascular disease and type 2 diabetes
Visceral fatFat stored in the abdomen around your internal organsToo much visceral fat can put you at greater risk of diabetes, heart disease, and some cancers
Fat-free massAll non-fat components of the body including muscle, bone, organs and waterPreserving fat-free mass is a key part of quality weight loss as it supports strength and physical function

Targeting visceral fat to achieve quality weight loss

The goal isn’t just to lose weight, it’s to lose it in a way that supports your long-term health.

To self-monitor your quality of weight loss and visceral fat, try the Waist-to-Height-Ratio (WtHR). Using this measurement gives you a clearer understanding of your weight, remember to aim for less than 0.5. Try it here.

 To dive deeper you can also speak to your doctor about an MRI (Magnetic Resonance Imaging scan), which is the more effective way to tell if you are storing too much visceral fat.

What quality weight loss looks like in real life

Focusing on ways to reduce visceral fat while preserving muscle is what makes weight loss more beneficial for your health.

Imagine two people in their 50s who both lose 10 Kg over the course of a year:

  • Sarah loses weight quickly, but a significant portion comes from muscle as well as fat. She notices everyday tasks, like carrying shopping bags or climbing the stairs, feel just as challenging as before.
  • David also loses 10 kg, but most of the weight lost is excess body fat while he maintains more of his muscle mass. He finds it easier to move, feels stronger during daily activities and sees improvements in health markers linked to weight management

The scale shows the same result for both people, but their outcomes can look very different. Preserving muscle while losing fat is one of the key reasons quality weight loss matters.

By looking beyond the scale, building sustainable habits, and tracking your progress in different ways, you can work towards weight loss that truly supports your body.

Small consistent habits can make a big difference over time. For example:

  • Eating a balanced, nourishing diet
  • Staying active regularly
  • Getting good quality sleep
  • Managing stress levels

Sleep and stress can both play a role in weight management, and ongoing stress has been associated with visceral fat accumulation. That’s why prioritising sleep and finding healthy ways to manage stress can be part of a quality weight-loss approach.

Getting support from a doctor can also help you find the right approach for your body. You can find more information to support those initial consultations here.
