چکیده انگلیسی
This study investigated the effects of hydration status and fluid availability on appetite and energy intake. Sixteen males completed four 24âh trials, visiting the laboratory overnight fasted on two consecutive days. Standardised foods were provided during the 24âh and on day two an ad-libitum semi-solid porridge breakfast was provided. Water intake during the 24âh (0 or 40âmLâ
kgâ1) and fluid provision during the ad-libitum breakfast were manipulated so subjects were euhydrated with (EU-F) and without fluid (EU-NF) available at breakfast; and hypohydrated with (HYPO-F) and without fluid (HYPO-NF) available at breakfast. Blood samples (0 and 24âh), urine samples (0-24âh) and subjective responses (0, 24 and 24.5âh) were collected. HYPO trials decreased body mass by ~1.8%. Serum and urine osmolality increased and plasma volume decreased during HYPO trials (Pâ<0.001). Total urine output was greater during EU than HYPO trials (Pâ<0.001). Ad-libitum energy intake was not different between trials: 2658 (938) kJ (EU-F), 2353 (643) kJ (EU-NF), 2295 (529) kJ (HYPO-F), 2414 (954) kJ (HYPO-NF), (Pâ=â0.131). Fluid intake was ~200âmL greater during HYPO-F than EU-F (Pâ<0.01). There was an interaction effect for thirst (Pâ<â0.001), but not hunger or fullness. These results demonstrate that mild hypohydration produced by inadequate fluid intake and fluid availability during eating does not influence ad-libitum energy intake of a semi-solid breakfast, at least in healthy young males.
