A pound of peanut butter is around 2600 calories. A pound of Nutella is about 2400 calories. Honestly not as bad as I thought initially.
1 to 2 pounds a week is 370 to 740 calories per day. Eating that much peanut butter for a week or so wouldn’t be too hard, but keeping that rate up consistently would be tough.
That's nuts (sorry). 400 calories of peanut butter is only 2 servings, 4 tbsp. I'm a big PB fan as well, and can easily eat 2-3 servings a day. I wonder if other nut butters have the same risks and would make good alternatives.
