Um . . . no.
1 kilogram = 1000 grams
1 kilogram = 2.2 pounds
So, 500 grams = 1.1 pounds
Therefore, 150 grams = (roughly) .33 pounds.
Stop panicking. You’re not going to die of meat poisoning.
You forgot that meat is something like 75% water by weight. So yes, it’s a fair amount of food, but by no means an unreasonable amount, especially if you avoid junk food.
Huh?
This would be correct if 93% lean burger meat were 100% protein. But it’s not, so you’re completely, disastrously, embarrassingly wrong.
According to the nutritional figures on this page, 95% lean burger has 22.3g of protein in every 3oz patty. That’s about 7.4g/oz.
So, to get 150g of protein from 95% lean burger meat, you’d have to eat 150/7.4 ounces, or 20.27 ounces of burger meat. That’s a pound and a quarter.
Oh, fine. Be all reasonable and knowledgeable. See if I care.
