Unfortunately this is not an uncommon scenario. Many people intending to make lifestyle changes procrastinate as they are not sure which eating plan or exercise programme will suit them best. The result is either total inaction, or the constant chopping & changing described above.   Underlying this problem, are two faulty assumptions: Firstly, that there is indeed one perfect option which is much better than all the others, and secondly, that if one takes one’s time and thinks long and hard enough about it, one should be able to identify this perfect solution.   Both of these assumptions are inherently incorrect. There are simply too many factors involved in determining which option will work best, at any given moment. Often, setting out on this impossible quest for certainty is nothing more than avoidance behaviour.   Maybe one day we will indeed get to the point of being able to pin-point exactly what approach is going to work best for any particular person, at a particular time, under specific circumstances. Until then however, my client will accumulate far more health benefits by making sure that he is fully committed to something (that is even reasonably helpful), at any given moment.     It is key for him to understand that there is nothing wrong with gathering information on other options, as long as in the meantime he is in fact still fully committed to something. Also, that he only make a change once (a) he has properly followed through on his current choice, and (b) has clarified the specifics (what, when, where, how, etc) of his next decision.   Over time then, one properly tries out different options. This process of doing a series of ‘experiments’ is in fact currently our best hope of finding what works optimally for any given individual.   In short - it’s not about finding 100% certainty about which is the best path for you, but rather about committing 100% to your current, chosen path.
