This is an excellent explanation of the difference between being interested in something and the commitment to something. Don't just be interested in health and fitness, make the commitment to yourself to change whatever you need to in order to live a healthier life!
People ask me some of things I do differently when it comes to eating. Because fried foods were a big part of my unhealthy eating habits, that was one of the first things I quit eating. There are many healthy alternatives to foods that may not be the best for us. Keep an open mind and try new things!
