There are hundreds of workout programs and diet plans out there claiming to be the best. Many of them are solid programs that can produce great results. Unfortunately there is no “one size fits all” program.
Its important to understand that everyone is different. Some people will lose weight on a certain diet plan and some will not. There are many factors that play into these results.
The best program is one you can stick to consistently. It shouldn’t take over you life or cause added stress. It should create a positive change and improve your well being.
If you feel the need to try a diet or workout program make sure you stick to it. Trying something for a week will not change anything. If you are consistent for several months and still don’t see the progress you want, then revaluate and try something else.
