Inget fett på morgonen?

Varför ska man inte äta fett på morgonen?

[King Grub]

Därför att det sänker insulinkänsligheten bra många timmar framåt. Gäller främst mättat fett. Och det handlar inte om "inget fett" - behöver inte överdriva - , utan mycket fett.

"A small difference in fat intake at breakfast has a large influence on circulating diurnal NEFA concentration, which it is concluded influences adversely glucose tolerance up to 6 h later."

British Journal of Nutrition, Volume 80, Number 4, October 1998, pp. 323-331 (8 ).

"Postprandial insulin sensitivity (SI(Oral)) was assessed for 180 min after each meal. SI(Oral) was significantly lower after lunch than after breakfast for all four test meals (P=0.019) following the same rank order (SFA < n-6 PUFA < n-3 PUFA < MUFA) for each meal. The present study demonstrates that a single meal rich in SFA reduces postprandial insulin sensitivity with 'carry-over' effects for the next meal."

Ok. Tack!

Det beror alltså på att man fastat under natten?
