I did exactly what you suggested, using the AD at the start of 07 for about 6 months and the 2day carb ups led to a massive gain in weight, and along with it, FAT!..I got soooo carried away with the scale going up and the t-shirt getting tighter, that I ignored the ridiculous fat gain and how shit I looked without a t-shirt on.
In the end I bust my ass in the gym and diet etc, so that I dont have to be ashamed to take my top off at the beach, and only stuck wearing a singlet only showing of my arms. This is why I have strived to get lean and build LEAN mass, rather than just look big in a t. Having said this, everyone takes their own path, so no judgement on my end.
To each his own I guess. I’m not ashamed to take my shirt off either, it’s not like I’m rolling at a high bf%, my abs show, my chest is defined, I have shoulder seperation, a little love handle action isn’t a big deal, I’m not trying to be a model.
You can keep it under control just fine on a high carb diet by having carb cutoffs, and taking in the majority if your carbs pre-post workout, just like any other healthy diet.
