It's not even necessarily a matter of overeating for the animals either.
Consider for a minute that the standard practice to increase on-the-hoof weight for farm animals is to feed them grains. Grass fed cattle beef is naturally leaner than grain fed feed not beef. They get unlimited amounts of food when they're allowed to graze in a grassy pasture - they eat constantly. When they're on the feed lot, they're given a specific amount of grains, at specific times of day, not unlimited amounts of grain. They also don't gain muscle (meat) weight on the grains, they gain
fat.
Also consider: The recent trend in very lean pork products is due to the industry reducing the percentage of grains in their diet, not due to feeding them less food.
Most pet food companies now produce a reduced calorie product for pets who have become obese. Why are the pets too fat? The industry will tell you that it's from being fed from the owners' tables, given too many pet treats - in other words, eating too much. The way they're telling pet owners to help their animals lose the excess is just like what they tell people to do to lose weight: eat less, lower fat intake, exercise more. But if you look at the ingredients in dog and cat food, they're mostly grains. Pets have been fed from their owner's tables since just about forever, but they were never overweight until people started feeding them pet foods based on grains. A feral cat or dog will not be overweight, not because they're not eating enough (although they might not be), but because they're eating their natural diet whenever possible - one that's high in meat, with little to no vegetable matter.
This metabolic problem isn't unique to a very small percentage of the human population - any time you give a human or animal a diet which is composed primarily of starches and sugars when their natural diet is meat (or in the case of cattle, grass), they're going to gain weight, unless you so limit their food intake that they barely have enough calories to survive.
