Chances are you have been on the health and weight loss hamster wheel for a long time. Every new diet and/or exercise routine you try brings nothing but more of the same.
If you start a new technique or go back to one that has brought you positive results in the past with the same mindset you can guarantee that your results will be the same. With that said, there are weight loss methods that aren't healthy and can actually exacerbate health issues or create new problems. For this reason it is best to not assume that a program or technique is safe or healthy without doing research.
Diets that entirely cut out macronutrients (e.g., carbs) can have health implications that you may not be aware of. Exercise routines that do not balance the body's entire muscle system or do not take into account preexisting conditions can create injuries or make existing injuries worse.
Once you have determined that a program or routine is best for you, the next step is to check what other assumptions you are bringing to the table.. By this I mean your mindset. Are you spending your hard earned money and your limited time and effort on this program but deep down you really don't believe it will work, or you see it as deprivation and punishment?
We all make assumptions and when they go unchecked, we fail to see where the root of the problem is and therefore are constantly stuck on the never ending wheel. Healthy eating and exercise are two excellent modalities but usually aren't enough to get us to reach our goals. Understanding your conditioning is crucial and no one can address what they cannot see. Make a list of all the assumptions you are making about diet and exercise before you start another program so what has been unconsciously stopping you is finally illuminated and can be worked with.
