Cats are showing aggression

I recently had both of our cats to the vet. He recommended that I stop leaving a dry food dish down at all times as one cat is too heavy.

He recommended 7 to 9 kibbles per feeding 3 times a day.

The girls were constantly crying and after about a month I increased the portions to 2 Tabelspoons 3 times a day for the heavier cat. 1 tabelspoon a day for the smaller cat.

Silver, my heavy cat lost quite a bit of weight. Ruby the smaller one seems about the same. This has been their diet for about 5 months now.

I have noticed that they seem to fight more now. Before they would frolick and play. Now I hear hissing and Silver in particular seems much more aggressive.

Do you think this has something to do with a diet change? Are they getting enough food?
