Congratulations on keeping off 19 pounds as well as being sober for over two years. That's fantastic. It's also fantastic that you're being active. Exercise is an important part of our long term health.
But, so is eating right. I won't call it "dieting". However, I do need to be honest. A person can't outrun a bad diet with exercise. If you want to take the weight off and keep it off, you need to eat right first and for most. Good nutrition is what takes the weight off and keeps it off. Exercise is what keeps our bodies fit and healthy.
Because let me ask you this, what happens if you become injured ? What happens when you have to stop exercising for whatever reason ? I'll tell you, the weight packs back on. That's why it's important for people to eat right to the best of their ability. And that doesn't mean starve yourself. Too many people think that they have to drastically cut their calories in order to lose weight. This is a misconception. While it's true the many Americans eat too much and need to eat less, the problem is that they are eating too much of the wrong food and not enough of the right food.
Quality of the food you eat has a huge impact on your health as well as your weight. One good way to improve your health (and help the scale decrease) is to eat 6-9 servings of fresh fruit and veggies. Eating that many veggies each and every day can and will make a difference. If you find that 6-9 servings is too much. set a goal to eat 2-3 servings each day for one week. Once you've achieved that goal, you set a new one. You keep adding servings until you are eating at least 6-9. that's one way to help you eat more veggies.
Also, one thing you don't want to do is look at weight loss or good health with an all or nothing mentality. You've been making great progress ! You don't have to be perfect to be healthy. Keep making those small changes like you've been doing. One thing at a time so that you don't become overwhelmed.
Educate yourself. If you want to be a healthier person, read as many of the different Spark articles you can. There are ones on nutrition, exercise, well being, etc... the better educated you become about your health, the easier things will get with time.
But you need to be patient with yourself and your body. Slow and easy really does win this race.
