Beta keto acids

BITSAT 2015 Coaching › Organic Chemistry questions › Beta keto acids

Why are beta keto acids unstable?
Or the other way round....Why do beta keto acids undergo decarboxylation easily?
Can't just find a good reason for this.....

Decarboxylation is easy for beta-keto acids because the ANION INTERMEDIATE is STABILIZED BY RESONANCE or the acid forms a more STABLE CYCLIC INTERMEDIATE via intramolecular H-bonding.During this process, CO2 is lost and the orginal beta-keto acid is converted into a ketone
