3 Fitness Myths That Are Still Costing People Progress

In this episode of The Bodybuilding Dietitians Podcast, we work through three of the most persistent fitness myths we see in practice and online. We start with detox diets and elimination diets, covering what the body actually does physiologically to manage detoxification, where clinical elimination protocols like low FODMAP have a legitimate role, and why the casual use of juice cleanses, skinny teas, and food group restriction tends to create more problems than it solves, including nutrient gaps, food fear, and a rebound dynamic that undoes whatever short-term progress you see on the scale.

We then move into waist trainers and spot fat reduction, unpacking why external compression changes how your waist looks without changing your anatomy, why spot reduction is not how fat loss works regardless of what it feels like when you are doing crunches, and what you should actually be focusing on if a smaller waist or leaner midsection is your goal.

We close on the carnivore diet and other major food group elimination approaches, looking at why some people do feel better initially when they cut out fibre, what is actually driving that response, and the longer-term cardiovascular and bowel health risks that the short-term wins tend to mask. We wrap up as always with what we learned this week.
