There's a saying in fitness circles: "You can't outrun your fork." Exercise is great, and you should do it, but reducing calories and changing their composition is far more impactful when the goal is losing weight. Even extremely vigorous and prolonged exercise burns only small amounts of calories.
That's a pithy saying and I think pretty accurate, but there is only so much I can manage my diet. The fact that I've maintained my weight for weeks and I'm extremely sedimentary says that the last 15 lbs is gonna involve a run. Good job diet in getting me back to my previous weight before I exercised. I think I'll get back to my goal weight by doing what I did before when I was at my goal wait: taking a 30mins run every day. That's just all that's left when you don't drink alcohol or soda or eat a lot of sweets or carbs.
