Not really. Healthy fats are your friend when bulking(well, fats are your friend period). Adding peanut butter and oils to shakes is a great way to pack in come calories. I remember a guy who had recipe for a peanut butter and coconut milk shake that was about 700 calories itself. Some of my favorite calorie dense bulk foods are:
Mixed nuts(almonds, walnuts, pecans, cashews and peanuts)are great because they require no preparation. Throw some in a bag and take them wherever you go.
avocados (avocado, mozzarella cheese, roma tomatoes, with some herbs drenched in olive oil is awesome!)
Shug’s morning hot protein and coffee drinks are awesome. Drink one or two of these(I have one with breakfast and take another with me for the drive to work)with breakfast and you are getting some extra protein to wash it all down.
You need to get creative with your food prep. Then it’s not nearly has difficult to get your bulk on.
