When summer approaches, plenty of people want to drop a few kilos before the beach or the pool. That is a fine short-term goal, but it raises a genuinely interesting question: when it comes to fat loss, fast or slow, which actually works better?
The old assumption
For years the common wisdom was that slow, gradual weight loss was always superior, on the theory that the habits built over a long, steady process are more likely to stick for good. It sounds reasonable. Recent research tells a more complicated story.
What the research actually found
A study from Melbourne University compared people who set out to lose weight rapidly against those aiming for a slower, steadier approach. The rapid group actually did better in the short term: 81 per cent of them successfully reached their target weight, compared to just 50 per cent of the slow group. The researchers suggested that seeing quicker results kept people more engaged and less likely to give up, with a stronger sense of day-to-day commitment carrying them through.
But is it all fat?
Rapid weight loss raises a fair question: is the weight coming off all fat, or is some hard-earned muscle going with it? A practical way to keep an eye on this is your strength in the gym. You might feel tired during an aggressive fat-loss phase, but your lifts should hold roughly steady. If your numbers in the gym are dropping along with the scale, you are likely losing muscle as well as fat, which is bad news for your metabolism and can set you up for rapid weight regain later.
The uncomfortable finding on keeping it off
Here is the sobering part. A separate Melbourne University study found that regardless of whether weight was lost quickly or slowly, there was no meaningful difference in how much of it came back. In both groups, roughly 70 per cent of participants regained the weight within three years.
What this actually means for you
Fat loss, fast or slow, is not really the question that matters most. Whichever pace you choose, protect your strength along the way by keeping up resistance training and eating enough protein, and put real thought into what happens after you reach your goal weight, not just how you get there. If most people who lose weight eventually regain it, the real focus needs to be on long-term behaviour, not a short-term sprint to a number.
If you are chasing a shorter-term goal, that is completely fine, just go in with a plan for what comes next. Where do you want to be next summer, and the one after that?
