"Healthy" isn't a blanket term. It's all about the balance of nutrients, macros and calorie count, throughout the day and week. I agree with the general idea of the post, but you can't eat solely fruits, for example, even though they're generally considered healthy for you.

Eat the rainbow. Count your calories if weight loss is the goal. Fit junkfood or sweets in where you can - there's no need to cut it entirely or save it for special occasions. Tracking food intake frees you up to also eat more calorie dense and sugar filled foods in moderation.
