Interesting. I've always had best results from letting activity create a deficit rather than dieting - lost my first 65 pounds without dieting or knowing anything about nutrition.
Still, I'm watching what I eat this summer (no cookie dough shakes

)- but trying to lose fat through pure calorie restriction has never gotten me anywhere

- like you said, it's not a great long term strategy (not sustainable).
on topic: I'm adding some muscle mass this summer, but I'm also leaning out. started at 193 pounds, down to 184 now with minor but definite growth in the chest, arms, legs, traps and lats (everywhere I guess

). strength is up.
eating plenty on training days (3 days/week) and less on sedentary days. lean meat, oatmeal, olive and peanut oil(for frying), flatbreads, whey, veggies, beans, peanut butter, blue cheese . Gonna boost my activity levels after my upcoming deloading weeks to try and lose another 2-4% before the end of summer.
