The half-year performance, for the year to June, showed UK volumes 0.7% behind 2007.
Stella Artois volumes were down 0.3% internationally, with Beck's slipping 1.5%.
But Inbev managed to raise operating profit by 1.3% to Euro1.67 billion on revenue ahead by 4.6% at just short of Euro7billion.
Chief executive officer Carlos Brito said: “Our second quarter results were better then the first quarter but still below our aspirations.
“Although industry growth in some key markets is below last year, we delivered market share results in the majority of our markets.
“Our overall pricing is healthy, but rising costs continue to put pressure on our margins.”
InBev has launched Beck's Vier and Stella 4% in the UK in a bid to get consumers paying more for standard strength beer.
Internationally, Inbev expects to complete its acquisition of Anheuser-Busch by the end of the year.
“Our team, however, remains focused on driving our organic business” said Brito.
