Figure 5 - Energy balance 5 10 Although most people are able to sustain a calorie per day deficit of energy in the short term, in the long term it becomes much more difficult.

Basal metabolic rate, and energy burned through activity both decrease as a person loses weight, so in order to continue to lose weight dietary intake needs to be further restricted. Also, eventually a person s hunger often overcomes the voluntary restriction of food intake.
