If it were me, though, I would start cutting back on alfalfa hay now and start adding timothy hay to his diet.
My other one, Mr. Bubbles is an American. And he's quite a bit bigger. His weight on the same sugary diet went over 3 lbs. He was identified as being overweight by the vet when I had him in for his nail trim. I was very lucky he didn't get the same infection as Scruffy. He's not as active as Scruffy, but he's not a statue either. Once I fixed his diet, he's dropped down to 2 lbs 13 oz, which is good for his size.
My vet recommend a cup of veggies a day including red leaf, green leaf, romaine lettuces, bell peppers, can be given daily, unlimited Timothy hay daily, one tablespoon of Oxbow pellets daily; parsley or cilantro can be given no more than twice a week. Carrots can be high in sugar, but once or twice a week, they can have a quarter of a regular sized carrot.
If you have a lawn that is safe from dogs, cats or other predators and doesn't have fertilizer or insecticides, you can let them eat their fill of grass daily. Just watch them closely and don't leave them even for a second. You should probably get one of those collapsible enclosures to put them in so they don't wind up getting lost. Also keep an eye on the weather and temperature as heat or cold can kill them very quickly.
