A period in which average energy intake is lower than average energy expenditure.
Why Calorie deficit matters
A consistent, manageable deficit is the main nutritional condition required for body-fat loss, but a larger deficit is not automatically better.
A practical example
Reducing average intake by a modest amount while maintaining protein, resistance training and daily movement.
Common mistake
Cutting calories aggressively and judging progress from a single day of scale weight.
Keep the context in mind.
Training and nutrition terms describe general principles. The right exercise, intensity or food target still depends on your experience, health, goals and schedule.
Personalised coaching
Apply the principle to your own training.
A definition is useful, but your programme still needs to match your experience, schedule, recovery and goals.
