Are you also trying, like 95% of folks on here, to lose weight?
If no – then have biscuits, what’s the issue. Biscuits are always worth having.
If yes – then do something more interesting for as long as it takes to get the hunger to pass. No-one ever felt hungry during a sky dive, not saying you can make work that exciting, but you get the point.
Or have a cup of hot water (maybe put some stock cube in) – it triggers the ‘full’ receptors, albeit temporarily, but enough to get you to lunch.
And 3. A substantial proportion of the world feels like that every day, with no end in sight. You’ve got 90 mins till lunch. Quit your jibberjabber and suck it up.
