Weight Loss Plateaus: Why They Happen and How to Break Them

You were losing steadily, then the scale froze for two, three, four weeks. Frustrating, but almost always explainable. Here’s what’s really going on and how to restart progress without panicking.

First, is it actually a plateau?

A few flat days are just water noise. A true plateau is three-plus weeks with no change in your weekly average. If it’s been less than that, keep going — you may not have plateaued at all.

Reason 1: Your maintenance dropped

A lighter body burns fewer calories. The deficit that once worked has shrunk as you lost weight. This is the most common and most legitimate cause.

Reason 2: Tracking drifted

Portions creep up, bites go unlogged, and estimates slide over time. Re-tighten your tracking for a week — weigh foods again — and the deficit often reappears on its own.

Reason 3: Less daily movement

Diets can unconsciously make you move less (NEAT drops) — fewer fidgets, slower walking. Your workouts may be intact while your background activity quietly fell.

How to break it

• Recalculate your calories for your new weight and trim 100–200 if needed.
• Tighten tracking for a week to check for hidden creep.
• Add movement — a daily step goal is the easiest lever.
• Consider a diet break at maintenance for a week or two to reset adherence.

Re-tightening is far easier with fast logging — Fotocal makes a “precision week” painless so you can spot exactly where the extra calories crept in.
