Gym sabotage

Today i was supposed to go to the gym with my gym buddy, but he is sick. I chatted with him for a little bit and it just comes down to him eating fast food and then he gets acid reflux, but he uses like a fancier word for it so it doesn't sound as lame. He thinks that him going to the gym will fix it cause "he will lose weight" not understanding that diet is like 90% of the process, and if you want to lose weight you need to eat less. My roommate eats like shit most of the time, and he is a skinny bitch lol. My gym buddy doesn't believe that and/or uses the "fast metabolism" argument, which is cope. I told him that it's not even about what you eat, but how much you eat of it. It frustrates me a lot cause he is sabotaging both himself and me by doing this. He is also aware that fast food is doing this to him and it feels unfair that he eats fast food the day before we go to the gym cause he knows it will f him up. So what gives??? Very annoyed. At this point i'd rather just not have a gym buddy tbh. I also realized that in the months he worked out with our PT he barely lost any weight, while at minimum he should've lost 7kg/15.5lbs. He is fat and didn't do anything for months/years. So him going to the gym should've kickstarted his body into losing fat more, which is obviously not happening. Tragic. Also disappointed in my PT for not pushing my gym buddy harder. If i would have a client like him i would tell him that i would drop him if he doesn't start eating healthier or get help/therapy for his eating habits, cause this is ridiculous.

Well anyways, atm i have a small mouse in the bucket, and i need to walk my dog, go to town, and i want to work-out at home. I'll just do two at home sessions this week i guess. Just need to check what i want to do today. Better get my ass into gear.
