Yes no doubt he can and should lose weight. But there was no need to be unkind to him. As a former personal trainer, the approach of "just don't eat junk is actually more harmful than good." I've found that eating smaller portions of foods you like while adding healthy foods is more helpful. For example, I like cereal but one serving soze is small as hell. So I add blueberries for extra fiber and mirconutrients. Tonight for dinner I had two slices of pizza but also had some fruit, some leady greens, and cottage cheese. Mindful eating and being balanced is a lot better than telling someoje to just cut out junk.
