It doesnt have to be one sitting. Eat 2500 diet and add a cup of roast nuts twice a day and you are basically there.

Moreover, you dont need to eat anywhere close to 5k to be morbidly obese.

1 cup of roast nuts over TDEE will gain you 100lbs in a couple short years

Assuming you maintain same activity level, the increase in weight wouldn't be that simple.

TDEE rises as body weight rises (heavier body burns more)

Overfeeding increases NEAT in some people (more fidgeting, movement)

I cup over TDEE will always be more as it raises
