The gravitational attraction between two objects will one object acquires more mass

The gravitational force between two objects is proportional to the
product of their two masses.  So if either object acquires more mass,
the magnitude of the gravitational attraction between them increases.

Here is a translation of the same statement, into simple English:

If you are on Earth, and your mass increases because you ate a lot,
then your weight will increase.
