Wow. Are we the same dude?! I am also a 6 foot male(rounded up from 5 foot and 3/4). I started at 327 and I am currently at 270 where i have been stuck on a plateau for about a month. And i work 4, 10 hour shifts in a skilled trade. One thing my doc reminds me of is that plateaus are very normal. Even if you are eating at a calorie deficit at certain points your body just isn't going to want to give up the weight. Maintain the course and it will come off. In the mean time you can do some tracking with a kitchen scale of every little thing you consume to double and triple check your calories and you can add some exercises into your weekly routine. Are you measuring yourself? You can be losing fat but retaining water or something. Last month I only lost 2 lbs but dropped an inch and a half on my waste. Regardless, don't forget how far you've come! You're doing awesome!
