I don’t know, I think there could be other factors. Are you getting enough sleep? Have you had any blood work done recently to make sure your hormones are all at good levels? Are you feeling stressed a lot? There could be some sort of hormone problem lurking under the surface, especially if you were taking medication previously that wrecked your body and sleep patterns. Is the sleep apnea still happening? Do you get good deep sleep at night? or is it light and do you wake up a lot in the middle of the night? That could make a big difference.
There’s some things that you could improve, but I don’t see this diet able to maintain 270 pounds.
You could ditch the “beef noodle soup” (I’m assuming this is ramen noodles, which I personally think are delicious, but acknowledge are a bad food source) and just add in the rest of the ingredients for an actual salad and not just eat lettuce. I feel like that would be the single best change you could make aside from maybe adding some more protein (you could possibly be getting enough, though; if your strength levels are still increasing, then adding more protein may just be adding more unnecessary calories).
Of course, with that being said, if your muscle mass is increasing from the 5/3/1 and your weight is staying the same, I suppose it’s possible that your weight is staying the same as a result. Does it seem like you’re carrying less fat? Do you have a way that you’re checking your fat percentage outside of how you look in the mirror and a weight scale?
You could be more concise with how many calories your dinner is, but unless you’re more than 300 calories off with your estimation, I don’t see this making a big difference. I’m thinking you’re savvy enough to at least be in the ballpark, but I may just be guilty of giving people too much credit.
Ditching the shot of brandy every night might not be a bad idea. It’s not a lot, but if you keep it to once every 2 or 3 nights or even once a week, it could help.
How long has your diet been like this? Did you just start it recently? or have you been sticking with it for a couple months or longer and still not lost any weight? Remember that results aren’t linear in many cases, so you may just have a short time period of no results, then start seeing them if you stick with the program long enough.
Also, I really like the predator conditioning article from earlier this month. You may want to consider dropping your last weight training exercise and putting more energy into some hardcore conditioning at the end of your workouts. You could do that and still stick with your 5/3/1. That could make your workouts more geared towards burning some of that fat off.
I don’t claim to be an expert, but these are my thoughts for what it’s worth. Could be way off, if so then please excuse my stupidity.
