let's talk physics

(Universal Gravitational Constant, G = 6.673 x 10-11 N m2/kg2)

Have you seen the above formula before? It's Newton's universal law of gravitation. this law extends gravity beyond Earth. This means Newton's law of universal gravitation is about the universality of gravity. Not only that, according to Newton, ALL objects attract each other with a force of gravitational attraction.

So, if we manipulate this formula, you could calculate the Force of attraction say... between Grinch and trees (assuming you know their masses).

Supposed, mass of Grinch, M = 60kg (Well I am, in case there are any doubters out there!)
And mass of trees, m = I dunno... maybe
2.0 x 1020kg
And the distance between me and the centre of those group of trees, r = 20m

So, if we input those data into the formula...

The Force of attraction between us is 2.0 x 109N or 2.0 x 109kgms-2 (which is quite high)
So meaning, I love trees! :D

This means, if we increase both M & m, (not just in our diet), the two objects will have a higher force of attraction. Can this apply to your other half, you asked?

Just visualise, if you and your partner have massive M & m, it can mean both of you will be attracted to each other more than if you are both so skinny. This is assuming if both of you remain close (r) though. So keep your r close if you want sparks to continue.

Next time if your girlfriend asks if she looks fat in her new dress, quickly input the above formula in your head, reduced the r (move closer to her), and tell her that she's not and she looks beautiful.

Let this formula be your guide.

See! Physics is fun!
