I'm just gonna weigh all the food I eat and measure how long it'll take me, I'm aiming for less than a month but that's still loads
Might need more than a month.
According to your profile, you are 220 lbs. The average human eats about 3-4 lbs of food a day. This comes out to 55 days.
Hypothetically speaking, you could eat 8 lbs of food in a day and make it in 27 - 28 days. However, based on my experiences with stuffing my feedees all day for extended stretches of time, you won't be able to eat that much consistently.
Also, depending on your current capacity, you may be unable to eat 8 lbs in a day. You'd need to train yourself to eat that much.
