AB  - Because day-to-day food intake varies, we tested the hypothesis that ad libitum 
      food intake and energy expenditure show corrective responses over periods of 1 to 
      10 days in healthy young women. Food intake and accelerometry measurements were 
      collected daily for 17 days in 15 young women. Total daily energy expenditure 
      (TDEE) using doubly labeled water was also measured. The daily deviations in 
      macronutrient and energy intake and energy expenditure from the average values 
      were compared with the deviations observed over succeeding intervals to estimate 
      the corrective responses. The intraindividual coefficients of variation for 
      energy intake averaged +/-25%, ranging from 16% to 34%. TDEE had a coefficient of 
      variation of 8.3%, and accelerometry had a coefficient of variation of 8.4% 
      (range=4.6% to 16.4%). Energy expenditure by accelerometry (2,087+/-191 kcal/day) 
      was not significantly different from TDEE (2,128+/-177 kcal/day), but reported 
      daily energy intake was 20.4% lower (1,693+/-276 kcal/day). There were significant 
      corrective responses in energy from fat and total energy intake. This occurred 
      from Days 3 to 6, with a peak at Day 5 that disappeared when data were randomized 
      within each subject. Human beings show corrective responses to deviations from 
      average energy and macronutrient intakes with a lag time of 3 to 6 days, but not 
      1 to 2 days. These corrective responses are likely to play a role in bringing 
      about weight stability.
