Good effort, cutting out booze will lower your estrogen levels and decrease your moobs. Cut right down on carbs, especially sugar.
You need around 13 inches (lean, no fat) around your calves and a similar mass of meat around your upper arms to be healthy, depending on height.

PS. You don't need a gym.
Get some resistance bands, a couple of 5kg dumbbells and a couple of hand grips, use them for intermittent short bursts of reps frequently through the day.
Carry the resistance bands and hand grips around with you, they're very conveniently portable, you can use them while working at your desk, while push ups and squats you can do anywhere.
Just keep moving, your chair's the biggest killer you've got.
Do squats and pushups. Do the lot, half an hour a day
