Where I'd suggest you go too far is implying that saturated fat and sugar are similarly bad. Technically you do hedge the claim with "excess", which is effectively a tautology, so the claim isn't outright false. You also don't qualify whether you mean excess in absolute terms (i.e. caloric intake) or as a proportion of macronutrients.
In practical terms, I don't consider it useful guidance based on the available evidence. As far as I can tell, there's little to no evidence that saturated fat is unhealthy (but lots of bad studies that don't prove what they claim to prove). Meanwhile, the population-wide trial of reducing saturated fat consumption over the past half-century has empirically been an abject failure. Far from improving health outcomes, the McGovern committee may well have triggered the obesity epidemic.
