What actually happens when you lose weight fast… 📉
We seem to be conditioned into expecting extremely rapid weight loss when we start a new diet or exercise regime. Social media is also full of promises of diets that will help you ‘lose 5kg in a week’. I can see why it’s tempting and I can also see why it’s nice to lose large amounts of scale weight when you start a new diet, and why it’s easy to feel disheartened if you don’t.
First things first, remember weight loss is not the same as fat loss. You’ll see lots of diets promising x kg loss in a week etc. What these diets – be they juice cleanses, ‘detoxes’, 7 day challenges, fasting, keep etc , don’t explain is that if you did indeed see that amount of loss in a week then it wouldn’t be fat loss. The harsh reality is that most of that weight loss is actually water weight, stomach contents, and a fraction of that is also muscle , and only a little bit of actual fat. Plus if it’s a particularly restrictive diet or is using pseudoscience to back it up it can also mess up your relationship with food and mental health.
Weight loss and fat loss are not the same thing. It’s quite easy to manipulate water weight by consuming fewer carbs (as 1g carbs binds approx 3g water), reducing salt intake or using diuretics (which increase the amount of water and salt excreted in the form of urine). This is how some athletes cut a few kg in the week before a competition.
So what should you do?
Do not crash diet – please! Instead try to make sustainable longer term changes to your calorie intake. A moderate calorie deficit will allow you to lose sustainably and steadily (an average of <1% body weight/ week). Shift your expectations away from big scale losses as a measure of success each week and instead look at long term trends and changes in things like clothes size, or measurements or progress photos rather than the scales.
