We deduce, as a consequence of the arithmetic removal lemma, an almost-all version of the Balog-Szemerédi-Gowers theorem. It states that for any K ≥ 1 and ε > 0, there exists δ = δ(K,ε) > 0 such that the following statement holds: if |A+ΓA| ≤ K|A| for some Γ ≥ (1-δ)|A|2, then there is a subset A' ⊂ A with |A'| ≥ (1-ε)|A| such that |A'+A'| ≤ |A+ΓA|+ε|A|.
