It’s hard for me to drink heavy cream but I can drink half and half like it’s milk. Will I get the same benefits of heavy cream (subcutaneous fat, delayed gain, etc) if I drink half and half?

Dont know if "half and half" is a product description in the US (Im from germany) but what I do is mix half a liter of heavy cream with half a liter of chocolate milk and drink that in a few minutes. Its 2000 calories and taste basically like slightly thicker chocolate milk.
If you like chocolate milk then I can recommend trying that
