My weight loss has stalled, OMG – now what? (Part 2 - Set Points)

If Part 1 was about eating too little (the most common stall cause we see), Part 2 is about the sneakier one: set points.

Look at my own weight graph from a while back. For nearly three full months, I bounced around 228 — up a pound, down a pound, nothing. Then, in the last few weeks of that stretch, I dropped to 217 like someone cut a rope. That's a textbook set point break.

Here's what's happening. Your body has a built-in weight thermostat — an ancient survival system designed to keep you alive when food is scarce. When you cut calories, your brain's weight control center (the hypothalamus) fights back using hormones like leptin, ghrelin, and insulin. It slows your metabolism, makes you hungrier, saves energy, changes how you store fat. In short: it does everything it can to hold you at the weight it's used to.

That's a set point. And the cruel part is that after years at a higher weight, your body defends THAT weight like it's the correct one.

The good news — and this is where the medication earns its keep: GLP-1s work directly on that signaling. They quiet the hunger hormones your body is weaponizing against you. That's a big part of why patients on Semaglutide or Tirzepatide can push through plateaus that stopped them cold on every previous diet.

The practical takeaways from watching 1,300+ patients break through these: stay consistent through the flat weeks (the break often comes suddenly, like mine did), keep protein high so the weight you lose is fat, and use your 3D scans — your body is often changing shape even when the scale is staging a protest.

Stalls aren't failure. They're your body negotiating. Hold the line.
