Why has my weight loss all but stopped?

I’m 5’11 and around 185 lbs. I started off the landscaping season at around 215 in early April. By early May I had already lost 25 lbs and noticed and increase in muscle mass just from raking leaves, pulling weeds, and trimming bushes etc. It is basicly light cardio for 30-50 hrs a week lol. Unfortunatly I then started working at darien lake and I re-gained like 5 lbs. Normally I would be doing alot of heavy lifting and bulking up right now…but I just walk around/drive a tractor all day. :tdown:. I want to join a gym or something to try to get back into shape alittle more. I have tried to cut my junk food intake which is quite high latly and I’ve been drinking 5-6 bottles of water every day at work. (we get cases of them). Hopefully I can kick my heavy pop pepsi lol, I drink probably 3-4 gallons of pepsi a week…which is actually alot less than I use to.
