Abstract Recent evidence suggests better appetite control in states of high-energy flux (HEF) adults and lean children. Nevertheless, it is unknown whether this extends to youth with obesity. This study compares the effects low, moderate or HEF on short-term appetitive adolescents Sixteen obesity (12–16 years, Tanner stages 3–5, 11 females) randomly completed three conditions: (i) low-energy (LEF); (ii) energy (MEF; + 250 kcal) (iii) (HEF; 500 kcal). Energy was achieved MEF through elevated intake (EI) concomitant increase expenditure using cycling exercise (65 % VO 2peak ). Ad libitum EI, macronutrient relative EI were assessed at dinner, subjective sensations taken regular intervals food reward measured before dinner. dinner greater LEF compared ( P = 0·008), (REI) higher 0·003) < 0·001).
