Here's an analogy that nicely describes the weight loss process. It's called the water wheel effect. As water from a river drives a water wheel, the wheel starts spinning, which pushes the wheel to pick up more water and the wheel stays in motion.
From this point on, it takes very little water to keep it moving. The same thing happens with your fitness and weight loss goals. Once you get started with a plan and begin seeing results, you don't want to stop because you know it's working.
The critical thing here is making sure you are exercising patience, because fat loss can take weeks, months, and even years.
Hope this helps!
