If you’ve ever followed a diet under 1200 calories, you need to read this.
Not because I want you to feel bad about it.
Because I want you to understand what actually happened to your body.
And why perimenopause feels harder than it should.
The fitness industry sold you restriction in your 30s.
Then watched you enter your 40s with compromised bone density, a suppressed metabolism, and a body that no longer responds the way it used to.
And now they want to sell you the fix.
Here’s what they never explained.
There is a clinical threshold for underfuelling called Low Energy Availability (LEA). Below 30 calories per kilogram of fat free mass per day, your body stops prioritising bone remodelling, hormonal function and metabolic regulation.
Most women on sub-1200 calorie plans were well below it.
In younger women, LEA shows up as a lost period, a clear warning sign.
In women over 40 with irregular cycles? It gets written off as perimenopause.
The warning sign disappears.
The damage continues undetected.
You were never the problem. The prescription was.
The fix starts with knowing your actual numbers, your real energy requirement, your lean mass, your metabolic baseline.
