I believe you want to feed your cat 20 calories per pound a day. So a 16 pound cat is going to need 320 calories a day to maintain their weight. The cans will let you know how many calories there are per can.
If you are wanting your cat to loose some weight, you can feed for the ideal weight, or for 2 pounds less, I believe. So for a 16 pound cat, you can feed for 14 pounds: ie: 280 calories a day. A cat's ideal weight is based on the individual cat. Your vet could let you know if your cat should lose some weight.
There are a ton of different style wet foods too. If you want him to get some more water, you can try finding a food with a lot of gravy (my cats love Weruva Cats In The Kitchen Pouches). There's pates, chunks, etc. If you are concerned about how much water your cat is drinking, you can add a little warm water to his food to increase liquid intake. Some cats also prefer moving water, so a water fountain might be something you can look into in the future.
