Diet. Individuals on a high-fat diet have been shown to lose less fat in response to exercise than those on a high-carbohydrate diet.10 High intakes of dietary fat lead to a greater energy surplus which is then stored in depot fat cells, while blood fats and glycogen are utilised for energy. The benefits of exercise are thus at least partially negated by the effects of excess energy in the form of fat. Yet while this is known, it is often difficult to verify.

Recent research using radioactive isotopes has shown that people under-estimate the amount of energy consumed in their diet by around 30 per cent, and over-estimate the amount of exercise they carry out by about 40 per cent. The under-estimate of food intake is reportedly higher in women than in men and there are indications that women may unconsciously eat more after exercise, whether as a means of defence against fat loss or a reward for having carried out exercise. Particular attention therefore needs to be paid not only to the fat content of the diet as a whole, but to the compensatory energy intake following exercise in some women. It’s not dear whether different types of exercise have different effects on this level of compensatory eating.
