Losing weight and getting healthier are not always the same thing.
When you lose weight rapidly, your body breaks down both fat and muscle tissue. The faster the loss, the greater the proportion of muscle sacrificed. Long-term clinical data now confirms that up to 40% of rapid weight loss can be lean body mass - not fat.
And the consequences of that muscle loss compound over time.
Your resting metabolism slows - making weight maintenance harder. Your insulin sensitivity worsens - because muscle is your primary glucose disposal organ. Your biological age advances faster, low muscle mass is one of the strongest independent predictors of all-cause mortality. Your bone density declines, particularly in women over 35.
These are not theoretical risks. They are measurable biological events and they are entirely preventable if you know they’re happening.
Prioritise protein at 1.6-2.2g per kg. Resistance train. Take creatine 5g daily. And measure.
Not the scales. Your body composition. Fat vs muscle. Visceral fat levels. Lean mass by region.
The question isn’t how much you’ve lost. It’s what you’ve lost.
