A pound of peanut butter per week sounds insane but apparently it's only like 2 cups and I feel like that's an edible amount. It's a lot but if I really got a hankering for some PB I could do that. But then after a week I would be over it. I feel bad for this person though that apparently they think eating nothing but PB is healthy. A human body needs a variety of different foods and nutrients and evidently eating nothing but peanut butter isn't that.
Same thing happens to me; I'll get a massive craving for peanut butter and easily consume an entire family-sized jar in a week. And just like you I'll get over it and go months without.
I wonder what causes this? Not enough protein in my diet?
You probably have plenty of protein in your diet. Requirements aren't that high for it. They're not a complete protein either but easily become one when paired with stuff most of us eat anyway.
They're pretty decent for b vitamins and things like copper (which is used for iron absorption).
Long story short you probably just like PB. I mean it's nice stuff but easy to get sick of.
Was putting less than that per week in my morning weight-gain breakfast shakes. Worked for a couple of months until the kidney stones put an end to that. Could never gain on carbs alone.
Of course not, protein is very literally what gains are made of.
It occurs to me that you might have just been talking about gaining fat, which is also more complicated nutritionally than you might expect. Especially to do responsibly.
Glycogen also makes up a good amount of muscle mass. But there was more in the shake than just pb and carbs. I had calculated a combination of macros though all those notes are long gone now. A 1500 cal shake over the course of a morning plus what amounts to 3500+ calories per day, all pre planned did not foresee the kidney stones peanut butter and cocoa would produce.
