Well, I am certainly not going to defend myself, fully recognising my inferiority...
I don't understand this at all as you've always come across to me as someone of great discipline.
I was a little chubby in highschool but I changed my eating habits and started working out and leaned out. Went from a 36 waist size to 32 now which is loose but 30 would be tight. I struggled with the first few months but I was consistent enough, and by the time when I was 17 I was not fat anymore.
Most people who say they're dieting and exercising honestly don't do it properly or do it half assed, and when they fail they blame metabolism and genetics. It's a process that requires self motivation each and everyday. Granted, when you are obese it can be tough but it can still be done with patience and consistency.
Weight loss to me is more of a life style thing than strict dieting. I've found that calorie counting with decent protein intake = best for people who lift, and also doing cardio to the point where you burn 400-500 calories a day helps a lot. Today I had a gyro which was probably 650 cals and oats amounting to 260 cals with a glass of whole milk which I measured at 150. I burned 300 calories on the elliptical. I probably eat one more meal totaling 500-600 calories and I should be fine for the day. This is what I've been doing and I've maintained my strength, increased endurance and have gotten leaner. This is a plan anyone can follow, even those with busy schedules.
