When it comes down to it, burning more calories than you take in = weight loss. Whether that's exercising more, taking in less calories, or both. I work two jobs, train in agility three times a week and groom dogs every week. I'm way too busy to go to the gym. So because I can't make it to the gym, I'm eating healthier foods and limiting my sugar intake (cutting the colas alone has done wonders for me). I'm too busy to cook most days so what I do is I cook healthy meals ahead of time and freeze them so I can just pop them in the microwave when I'm ready. It seems to be working so far!
