A 300-calorie deficit is a conservative approach — sometimes called a "micro-deficit." Results are slow but body adaptation is minimal, making it easier to maintain long-term.
To achieve a 300-calorie daily deficit, the typical approach is a combination of dietary reduction (~60–70%) and exercise (~30–40%). For example, reducing food intake by 195 calories and burning 105 via exercise.
