Sometimes we tend to overcomplicate things, especially with regard to health and wellness. We overthink the details - do we work out first thing in the morning or in the evening? When do we eat? What kind of exercise do we do?
Until you are able to develop a workout and nutrition plan, your best option is to just do SOMETHING. Anyone can go for a 30-minute brisk walk. Anyone can do pushups and chair squats. The key is to start and keep working as you're learning the finer points of exercise.
What about your eating plan? Well, we all know what foods are really bad for us - fast food, sugary sweets, and soda - so it's easy to eliminate those things from our menus while we take the time to study exactly what it is we should be eating. We all know that drinking water is a better choice than drinking any other beverage, so it's simple to make that change.
Keep it simple. Make the best decisions you can at this point in time. When you are able to figure out the details, you can integrate them into your program over time. Start the process of fat reduction before you know everything, and then move yourself along the path more efficiently over time.
