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.
