how many days does it take a person to eat what they weight?

Have a go at estimating how much mass you each each day. If your mass is 80 kg, then the number of days would be
80 kg/(mass eaten per day).

To estimate how many days it would take for a person to eat what they weigh, we need to estimate the amount of mass they consume in a day. Let's assume a person's weight is 80 kg.

To get an estimate, you need to have an idea of how much mass a person consumes in a day. This can vary depending on their diet, metabolism, and other factors. On average, an adult consumes around 2,000 to 2,500 calories per day, which corresponds roughly to 0.5 to 0.6 kg of mass.

Using this estimate, we can calculate the number of days it would take to eat what you weigh:

80 kg ÷ 0.5 kg/day = 160 days (using the lower estimate)
80 kg ÷ 0.6 kg/day = 133.33 days (using the higher estimate)

Therefore, it would take approximately 133 to 160 days for a person weighing 80 kg to eat the same amount of mass if they were consuming an average amount of food each day.
