The power of a negative energy balance
Ian van der Werf
29 November 2025A negative energy balance - using more energy than you take in - is essential if you want to lose weight. But at De Werf we look beyond the scales. Because losing weight only becomes valuable when it helps you get fitter, stronger and more resilient - physically and mentally.
Why a negative energy balance works
When you are in a negative energy balance, a lot changes in your body. With proper guidance, it delivers not only weight loss, but also structural health gains. These are the five key effects we see at De Werf every day:
1. Responsible weight loss
Your body starts using stored fat reserves, leading to a decrease in weight and fat mass. This process is fundamental when overweight, but needs to be controlled to prevent loss of muscle mass.
2. Improved body composition
With the right guidance you mainly lose fat and maintain muscle mass - crucial for strength, posture and vitality.
3. A healthier metabolism
By strategically combining movement and nutrition, you reduce the risk of lifestyle diseases such as type 2 diabetes, cardiovascular disease and inflammation.
4. More mental clarity
Many clients notice they feel sharper, calmer and more alert when their nutrition and energy expenditure are in balance. Your body works more efficiently - and you can feel it.
5. Sustainable energy levels
It can be challenging at first. But with a well-attuned plan you'll find your energy increases, you sleep better and you feel fitter in daily life.
No crash diet, but a strategy with impact
A negative energy balance is not a quick fix. It is a strategic choice within a bigger whole of behavioural change, insight and guidance. That is exactly what we stand for at De Werf: a sustainable route towards your goals, without performance pressure or a standard approach.
