And so, the 30/30/30 method gained significant traction.

Not exactly controversial, but another rule overpromising on fat loss nonetheless.

What is Tim Ferriss' 30/30/30 rule?

At Tom’s Guide, we’ve previously consulted nutritional therapistKerry Beeson(BSc) for protein advice.

But again, you dont need to cram your protein into a 30-minute morning window.

The most sustainable method to promote fat loss through exercise is through consistency.
