Setting your number — how big a deficit is sustainable

Your daily calorie deficit is a choice you make. Pick one you can hold for months, not one you quit in a week.

You open Burnie and see 'daily deficit'. A number sits there. You wonder how big it should be. Bigger means faster, right? Not always. The number you can keep for months is the one that works.

What a safe rate looks like

Health bodies agree on a steady pace. One to two pounds a week is the safe speed. That is about half to one kilo. To get there, you eat 500 to 750 fewer calories than you burn each day. Faster loss sounds great, but it usually fails.

The biggest deficit gives you the fastest result.

mostly false

Mostly false. A huge deficit works for a few days, then people quit. Adherence — your ability to stick with it — drops as the deficit gets harsher. A moderate deficit you actually follow beats a harsh one you abandon.

Pick your deficit size

Small (250 kcal/day)
About a quarter kilo a week. Easy to keep. Good if you are close to your goal weight or new to logging.
Moderate (500-750 kcal/day)
About half to one kilo a week. The sweet spot most health bodies suggest. Most people can hold this for months.
Aggressive (1,000+ kcal/day)
Over one kilo a week. Hard to keep. Higher risk of losing muscle instead of fat. Talk to your doctor before going this low.

The bottom line

A moderate deficit you keep for months beats an aggressive one you quit in a week. Your number is the one you can actually live with. Set it from your own log, hold it, and let the maths do the work.
