I'm reading an intriguing book called "Brain Over Binge." I'm not a binge eater, but wonder if the principles in this book can be applied to the act of simple overeating. I often eat mindlessly and compulsively.
I'm on a chapter that discusses habits, and the author talks about how, when you do something often enough, it becomes a habit; almost second nature. This is because neurons can change in your brain. They form new connections that become stronger each time you perform a certain action. Likewise, unused synapses will weaken -- essentially breaking the habit.
I want to get rid of my bad habits and start new, good ones. I'm not sure yet how long it takes to form strong enough connections in my brain that exercising every day will become a good habit, or how long it will take the synapses governing my bad habit of compulsive eating to weaken. But I'll let you know.
