Remember when I raved about the dietary approach called If It Fits Your Macros, or flexible dieting? I experienced some significant personal growth with respect to the way I approached and related to food. I still believe that others can experience these breakthroughs via IIFYM as well. Not to mention, I and countless others have achieved significant changes in our physiques. But, at what cost? And were those changes sustainable? As I alluded in my How-To: Take a Break post, following IIFYM for a long-term, continuous basis is not feasible or sustainable. Like all diet plans and program, “flexible dieting” or If It Fits Your Macros has both benefits and pitfalls for its followers. I’ll be exploring the less desirable aspects of this program (and other “restriction diets”) in this post.
