The Häagen-Dazs Grapefruit Question

Of course any nutritionist worth their salt substitute could tell you a grapefruit is more healthful than Häagen-Dazs and blah blah blah. But what if it’s your charted destiny to consume coffee icecream blanketed in cinnamon, ideally having liberated it from Kitchen Table at 11:30 pm? (The walk there being exercise. Ish.)
     Then, the pressing question for nutritionists is actually:
     If, in a feat of extraordinary restraint, you’ve kept a quarter of the pint to scrape out of the container next morning for breakfast, wouldn’t mounding on 47 extra calories worth of grapefruit be somehow injudicious?

P.S. Never skip breakfast.
