ture, weight will be lost. Increases in energy
expenditure and moderate decreases in energy
intake may help preserve FFM and muscle
strength while dieting.



  • Rate of weight loss is important. Do not use
    severe energy restriction or fasting as a means of
    weight loss. For most athletes, a weight loss of
    0.5–1 kg · week–1is the maximum recommended.

  • Composition of the diet is important, espe-
    cially for weight maintenance. Carbohydrate,
    protein and alcohol oxidation appear to match
    their energy intake, while fat oxidation does not.

  • The protein/energy intake ratio is impor-
    tant. When energy intake is low, a higher
    protein/energy ratio is required. In addition,
    athletes have higher protein requirement than
    sedentary individuals.

  • Micronutrients are important. If dieting is
    longer than 3–4 weeks, micronutrient supple-
    mentation may be required to meet the recom-
    mended intakes.
