Week-by-Week Projection to Your Goal Weight

Most people draw their expected weight loss as a clean line from point A to point B. Real bodies don't behave that way. The first two weeks of almost any cut show an outsized drop — three to six pounds is common — because stored carbohydrate (glycogen) and its bound water flush out quickly when calorie intake drops. Weeks three through five settle into the honest pace that matches your actual deficit. Weeks six through ten slow down as your metabolism adapts. Weeks eleven and beyond require course correction to keep moving.

This calculator projects both lines. The dashed "linear" curve is the naïve math: deficit divided by 3,500 kilocalories per pound times seven days. The solid line shaves a small, compounding percentage off each week's loss to reflect the slowing that most people observe. If your real-world weekly average tracks the solid line, you're doing it correctly. If it tracks below the solid line after week four, you've either stopped being honest with your logging or your starting TDEE estimate was too high.

Reading the chart

Week 1 is a dead zone for judging progress. Week 2 is slightly better but still dominated by fluid changes. Real diagnostic information starts at the week-three weekly average. From there, compare your weekly average — not any single day — to the curve. A plateau that lasts 10–14 days inside a confirmed deficit is normal and usually resolves on its own. A plateau that exceeds three weeks requires intervention: recalc TDEE at your new weight, audit logging for hidden calories, and consider a diet break with the plateau calculator.

What drives the timeline

Three levers set your pace. The first is size of the deficit: larger deficits pull weight off faster but hit diminishing returns past 20–25% below TDEE because hunger, muscle loss, and training performance degrade non-linearly. The second is protein intake: higher protein (0.8–1.0 g per pound of bodyweight) protects lean tissue, which in turn keeps your TDEE higher and your loss more fat-weighted. The third is sleep: short sleepers lose the same total weight but a much higher fraction of it comes from muscle, which makes the curve in the mirror look very different than the curve on the scale.

Front-loading versus even pacing

You have two broad strategies. Front-loaded cuts run a larger deficit for the first 6–10 weeks when willpower is highest and novelty is carrying you, then ease to a smaller deficit for the final stretch. Even-paced cuts set a moderate deficit from week one and hold it. Front-loading gets you to 70% of your goal faster; even pacing is easier to maintain for cuts longer than twelve weeks. Neither is wrong — pick the one that matches your temperament and schedule.

Weeks 6–10: the danger zone

This is where most cuts die. Novelty is gone, the mirror hasn't caught up to the scale yet, social events accumulate, and adaptive thermogenesis starts making honest logs feel like they're not working. The rescue protocol is mechanical: recalc TDEE at your current bodyweight, take a 5-day refeed at maintenance, log every single input for a week without exception, and add 15 minutes of walking per day. Three out of four stalls dissolve in the next ten days.

When to declare the cut over

Stop when you hit the goal, when your weekly-average loss has been under 0.25% of bodyweight for three consecutive weeks at a real deficit, or when hunger and training performance cross a line you're no longer willing to tolerate. A finished cut needs a structured maintenance phase — 4–8 weeks eating at your new TDEE — before any future cut. Yo-yo-ing from one cut to the next with no maintenance is the fastest way to metabolic adaptation you can't easily unwind.
