Why give any grain at all if he's fat?
Horses generally don't need any other food than grass/hay/straw if they get this in a good quantity and a good quality.
But since we ride them and don't always have enough hay or good enough hay, many might need more to keep them in shape and to mix vitamins/minerals with if they need it.
If the horse is fat, the first thing to remove is the grain. Take an analysis on the hay (difficult when he's on grass perhaps) and only give him extra minerals or vitamins if he needs them. Make sure he gets enough protein and so on too.
It's also important that the horse (almost) always has something to chew on, even if it's just straw. It keeps the stomach working and since horses stomachs arn't like ours, an empty stomach means acid that causes ulcars etc. More than 80% of the horses that's in stalls with saw-dust(or the like) instead of straw, and that doesn't have free acces to hay, has ulcers when they die (according to an investigation made by vets). Only 20-30% of the horses standing on straw had ulcars. Horses that has acces to something to chew on also feels better mentally and don't get bad habits such as ''swallowing'' air and so on. I'm just saying this since a lot of people see that the hrse is fat and cut down on all food, or just cuts down on the hay.
If the hay is too good for him (=fattens him), mix with straw.
Other than that, excersise. Ride much in walk but in tough terrain if you can and if he's not fit for it, slowly work up the time he can trot or gait. Work him on long-reins or walk with him. I wouldn't advice you to lounge since it wears a lot on the legs, and they're already under stress from his weight.
Always keep your head up, but be careful to keep your nose at a friendly level.
