The answer is no. In the book, Tiny Habits, by Fogg, PhD, it’s more a matter of modifying design, rather than willpower. How can you modify your environment, along with tiny habits, to put you in a position to succeed, rather then simply focusing on willpower? Think designing better environments, for example. If refined sugar is an issue, can you swap in whole, sweet fruits to your environment (home and wherever you go) instead and swap out the refined sugar? A handful of cookies may be 300 cal whereas an apple is about 80 cal. Pair with a twice weekly food shopping habit to set you up for success. How to design your life with habits, routines and modifying your environment at home, work, on the road, winter, spring, summer and fall to get healthy food in front of you when hungry? Think strategy and design more than willpower and discipline to make it easier to succeed. Combine with tiny habits to simplify for success!
