I have a couple tablespoons of cream in my coffee every morning, and i just discovered the awesomeness of pouring some cream over frozen blueberries. I'm not overweight at all, I'm very active, and don't really consume anything else that is not pure paleo.
Good question. I used to ask myself the same thing.
I'm a big proponent of skipping breakfast and having only lunch + dinner. But being active, I've found that to keep energized at my work, I need an infusion of energy during that time. I do this by adding 1/2 cup of half&half (10%) cream to my 6am coffee and again to my 10am coffee. That cup of cream provides the following nutritional boost
Energy: 314.6kcal Protein: 7.2g Carbs: 10.4g Lipids: 27.8g
This may not work for everyone, but after 1 1/2 years, and considering my 155lbs frame, I can report that it has not had any detrimental effects on my 6-pack :) (that's my proud face right there)... and keeps away any hunger pangs till lunch (even till dinner sometimes). Coffee purist will balk at my ritual... but I quite like it.
I also make my own yogurt with 10% cream only. Yeah, I'm a big fan of cream.
