I hear ya. Maintaining weight is not easy, that's why I don't do it. I'm always aiming to reduce weight. Doesn't mean I always succeed. And that's okay. The point is the mindset. Not looking to remain steady but to keep improving, the body will take care the rest. As far as tracking things such as calorie and macro-nutrients, I just go with common sense and listen to my body. Check out my blog about Goldilocks. I find that much easier to follow than an app. That's just me. Whatever works, right?
