You feel stronger. Your muscles are pumped. Motivation is high.
Then you step on the scalesโฆ
And your weight has gone up.
So what's going on?
First of all โ this can be completely normal when you start strength training.
It doesn't mean you've suddenly gained a load of body fat.
As you train, your muscles can increase their glycogen stores. Glycogen is stored alongside water, so changes in training and carbohydrate intake can produce a noticeable increase in body mass.
That's water โ not overnight fat gain.
And then there's another factor people often overlook:
Exercise doesn't automatically create a huge calorie deficit.
The calories burned during training can be smaller than many people realise, and exercise can also influence appetite and how much energy you expend during the rest of the day.
That's where NEAT โ Non-Exercise Activity Thermogenesis โ comes in.
NEAT is the energy you use for everything outside deliberate exercise: walking, standing, moving around, household tasks and even spontaneous movement.
For some people, increasing structured exercise can be partly offset by reductions in everyday movement.
Then there are the calorie estimates from watches and fitness apps.
They're useful for tracking trends, but they aren't precise enough to treat exercise calories as an exact food allowance.
So if your goal is fat loss, focus on the bigger picture:
Your long-term energy balance matters far more than what your watch says you burned in one workout.
And don't judge your progress from a single weigh-in.
Your scale weight can fluctuate because of water, glycogen, food volume, sodium, hormonal changes and training-related inflammation, as well as changes in body fat.
Strength training can build a stronger, more capable body while the number on the scales temporarily moves in the opposite direction.
The scale doesn't lie.
It just doesn't tell the whole story.
