Why diets fail - and what works instead

Failure Is the Norm

Let’s start with an uncomfortable truth: 95% of all diets fail in the long run. Within 1–5 years, most people regain the weight they lost—and often even more. This isn’t just an anecdote; it’s the result of decades of research.

Nevertheless, the diet industry makes you feel like you’ve failed. In fact, it’s the other way around: the system has failed. Your body is functioning exactly as it should—it’s fighting against the restriction.

The Biology Behind the Yo-Yo Effect

Set-Point Theory

Your body has a "comfort weight"—a set point that it actively defends. When you drastically reduce your food intake, your body interprets this as a famine and activates countermeasures:

• Your metabolism slows down—you burn fewer calories
• Ghrelin rises (hunger hormone)—you get hungrier
• Leptin drops (satiety hormone) — you feel less full
• Cortisol rises — stress that leads to emotional eating

Metabolic adaptation

After a crash diet, your body burns up to 500 kcal less per day than before the diet — even if your weight remains the same. This effect can last for years. This explains why so many people weigh more after a diet than they did before.

Diet Mentality vs. Body Intelligence

The diet mentality is characterized by:

• All-or-nothing thinking — “I ate a piece of cake, now the day is ruined”
• Forbidden foods — the more you deny yourself something, the more you want it
• External rules — apps, points, calories instead of body signals
• Reward and punishment — exercise as punishment for eating, deprivation as an achievement

Body intelligence is the opposite: trusting your body’s signals. Hunger, fullness, appetite — these are not enemies. They are information.

Important note Crash diets can slow down your metabolism in the long term and increase the risk of eating disorders. Always speak to a doctor or a specialized counselling centre if you are suffering severely.

What works instead

Intuitive eating

Intuitive eating means listening to your body’s signals again and trusting them. It’s not “eating whatever you want”—it’s about reconnecting with a natural relationship with food.

Mindful eating

Eat more slowly. Taste more mindfully. Enjoy without guilt. Mindful eating is the practical first step toward a new eating habit.

Joyful Movement

Movement that’s fun—not just to burn calories, but as a gift to your body. Dancing, walking, swimming, yoga—whatever moves you.

Self-Compassion

Research shows: Self-compassion is the strongest predictor of sustainable healthy behavior. Not discipline. Not willpower. Kindness toward yourself.

Your body isn't the problem

In a world that tells us every day that we need to look different, it’s revolutionary to say: Your body is okay just the way it is.

Body neutrality isn’t about “loving” your body (that can be a tall order). It’s about accepting your body and giving it what it needs—not as a reward or punishment, but out of care.

When you stop fighting against your body and start working with it, everything changes. Not necessarily your weight. But your well-being, your energy, your relationship with food—and ultimately: your life.

Is it really healthy to give up diets?

Studies show that the non-diet approach leads to better metabolic markers, fewer binge eating episodes and more stable mental health than classic diets - even if the weight remains the same. Health is not synonymous with a certain weight.

What about "healthy eating"?

Healthy eating means: predominantly whole foods, sufficient nutrients, regular meals - without prohibitions and feelings of guilt. The difference to dieting: there are no restrictions, no calorie counting and no target weight.

Can my set point change?

The set point can shift slowly over the course of a lifetime - in both directions. Drastic diets can shift it upwards (the body stores more as protection). Long-term, gentle changes in diet and exercise habits can slowly lower it.

What do I tell my doctor when he recommends losing weight?

You have the right to ask about evidence-based methods. Ask about specific health markers (blood pressure, blood sugar, cholesterol) rather than BMI. You can also ask for a referral to a weight-inclusive nutritionist.
