Counterregulation of insulin by leptin as key component of autonomic regulation of body weight

Figure 1 Correlation between energy expenditure and peak hunger in two studies in which exercise energy expenditure of between 2300 and 2500 KJ was inserted between the morning and midday meal (A) or between both morning and midday, and midday and afternoon, meals (B). Correlation coefficient between energy expenditure during overnight fast before the morning meal, and during morning intermeal interval that included exercise on one hand and peak hunger at the next meal was 0.06 in A. In B, the correlation coefficient between intermeal intervals that included exercise and peak hunger at the subsequent meal was 0.0002. Data from Ref. [69].
