To eliminate the confusion of choosing a tailored program or a specific diet, you may first want to consult your physician to discuss what the best options for you are.
Your physician may ask you to add a fitness program to your diet as well, or may require you to choose a specific diet if you have health issues. Meeting with your physician is especially important before starting a program or diet especially if your goal is significant weight loss.
Once you have decided on either a program or a specific diet, you will then be able to tailor your program or diet to meet your lifestyle and achieve your desired results.
