There’s a reason protein is the first thing I look at when someone tells me they’re barely eating.
Your body is remarkably adaptive. It can convert protein and carbs to fat, and fat (to a small extent) and protein can be converted into glucose for energy. But the reverse? Fat and carbs cannot be converted into protein. Ever.
Which means if you’re not eating enough, your body has one option. Pull amino acids from your muscle tissue to keep everything else running. Your immune system. Your hormones. Your enzymes. Your red blood cells. Every critical reaction happening right now depends on a steady supply of amino acids.
I had a client lose weight fast. About 4kg of that was lean mass.
Strength went. She regained the weight and it continued to creep further even though she wasn’t eating any differently. Felt exhausted. Couldn’t figure out why.
She wasn’t broken. She just needed consistent, optimised protein and progressive resistance training to rebuild. That takes time. Real time.
A few months to lose the lean mass. Close to a year to build it back.
This is exactly why, whether you’re considering a crash diet, Ozempic, Wegovy, Mounjaro, or weight loss surgery, my first thought is always: how much protein are you getting?
These tools can be genuinely useful for some people. But if you’re excited to lose weight as fast as possible, please slow down long enough to protect your muscle. The goal isn’t just a smaller number on the scale. It’s a body that’s actually stronger and functioning better on the other side.
Supporting weight loss is definitely something I do. I believe in a person’s right to choose what they do with their body. Just do it properly and safely. Your future self will thank you.
