A plateau is not always a stop
The number on the scales mixes fat, muscle, water and the contents of your gut. From one day to the next it can shift by a kilo or more without any change in body fat: a salty meal, a short night, the menstrual cycle or a hard workout is enough. Before calling it a plateau, look at the trend over three to four weeks, weighing yourself in the same conditions (in the morning, before eating, after using the toilet).
Your waist measurement is a useful extra: it can go down while your weight stays the same, especially when you start exercising again.
The most common causes
- Your body uses less energy: as you lose weight, there is less body to run and move around. The same intake as at the start therefore creates a smaller deficit.
- Portions creep up: after a few weeks, amounts tend to grow without you noticing. A well-known study found that people convinced they were eating very little were in fact underestimating their intake by almost half (Lichtman et al., 1992).
- You move less without realising: the tiredness of a deficit reduces everyday movement (walking, stairs, fidgeting), which counts for a lot in total expenditure.
- Weekends undo the week: a few large meals can cancel out part of the deficit built up over the previous days.
- Sleep and stress: too little sleep increases hunger and the appeal of fatty, sugary foods.
What to do when your weight stalls
- Check your portions for a week: weigh the most calorie-dense foods (oil, starchy foods, cheese, sauces) and note your drinks. That is often where the gap is hiding.
- Recalculate your needs at your current weight: a few kilos less changes your expenditure. Our calorie calculator does it in a minute.
- Add movement rather than cutting more food: an extra 20 to 30 minutes of walking a day adds to the deficit without raising hunger in the same way.
- Look after protein and fibre: they are more filling and help you stick to the deficit.
- Keep the same routine at weekends: you do not need to be perfect, just avoid repeated big departures.
- Give it two more weeks: a ten-to-fifteen-day plateau is common, and the drop often resumes all at once.
What is best avoided
Slashing your intake or skipping meals seems logical, but it increases hunger and fatigue and makes giving up more likely. Likewise, piling on intense workouts without eating enough wears you out and rarely restarts weight loss. A small adjustment kept up for several weeks beats a big effort abandoned after ten days.
What if you have reached a balance point?
Sometimes a plateau is simply a weight your body can hold comfortably. If your BMI is already in the so-called healthy range, moving on to keeping your weight stable may be wiser than trying to lose more. You can work out your BMI to see where you stand.
How the cure BalenZ programme handles plateaus
In the programme, the deficit is set phase by phase: larger in the first month, a little gentler afterwards, then a stabilisation phase. Your final review recalculates your targets at the weight you have actually reached. See How it works.
