Calorie Deficit Basics: A Realistic Starting Guide

To lose body fat you need to consistently eat fewer calories than you burn. That’s a calorie deficit – and it doesn’t have to be extreme.

Step 1: Estimate maintenance

A quick starting point is body weight in kg × 30–33 kcal. Use this as an estimate, not a rule, then adjust using real results over 2–3 weeks.

Step 2: Create a modest deficit

Subtract around 300–500 kcal from maintenance. Bigger cuts make hunger, fatigue and muscle loss more likely.

Step 3: Build meals around protein and fibre

  • Protein at every meal
  • Vegetables, fruit, pulses and whole grains for fullness
  • Limit liquid calories like sugary drinks and juices

Step 4: Track and adjust

Weigh yourself a few mornings a week and look at the average. If nothing changes for two to three weeks, trim 100–150 kcal or add more daily steps.

Not suitable for anyone with a history of disordered eating, pregnancy or medical conditions – speak to a doctor or dietitian first.
