We prove a law of iterated logarithm for random walks on a family of diagonal products constructed by Brieussel and Zheng (2021). This provides a wide variety of new examples of law of iterated logarithm behaviors for random walks on groups. In particular, it follows that for any 21≤β≤1 there is a group G and random walk Wn on G with E∣Wn∣≃nβ such that
