For years we have been told that the body defends fat levels through the Lipostat Theory and I have always admired it and spoken about it. But after working with people in my clinic and athletes in training programs, I keep seeing something interesting: People often lose fat very quickly. Sometimes within a week. But their body weight hardly moves.

And this happens even when I do not make them to eat less. Calories remain roughly the same. I only change things like movement, training, timing of food, and type of foods etc.

If fat was the primary variable the body was defending, this should not be so easy to cut away fat that easily?

So it raises a question –
What if fat is not the main thing the body is trying to protect?
What if body weight itself is the defended variable, and fat is simply the easiest tissue the body can adjust to maintain that weight?

Think about it this way –
– Bone does not change quickly.
 -Organs do not change quickly.
 – Muscle changes slowly.

But fat can expand or shrink rapidly.

So fat may act as a buffer that helps stabilize overall body mass?

Interestingly, newer ideas like the Gravitostat Theory suggest that bone cells such as Osteocytes may sense mechanical load and communicate with the Hypothalamus to regulate body mass. If that is true, the body may be trying to maintain a certain mechanical load, not just a certain amount of fat.

This may explain what I observe in my studies: Fat drops quickly. But body weight changes slowly. Which raises an interesting possibility:
– Maybe fat is not the controller.
– Maybe fat is simply the adjustable component the body uses to stabilize the system.

And if that is true, it may explain why improving how the system works through movement, training, and metabolic efficiency can reduce fat even without aggressively cutting calories.

Something worth thinking about.
