Why do so many fitness people eat so much sweet foods?

I‘m talking about fitness influencers to just people who are into fitness and post what they eat.

Idk if it’s just my perception since I personally don’t eat a lot of sweet foods (candy, desserts, cakes, sweet granola bars etc.) But so many of them eat that everyday like a chocolate or nougat proteinshake, protein chocolate bars in between, protein snickers cake, or porridge with chocolate sweetened protein powder honey etc.

I know that you should eat carbohydrates that are available quickly to your body before you have a workout, but to me the consumption of sweet food from other people seems so high
