We're obsessing over one nutrient whilst completely ignoring another that's equally crucial for weight management, gut health, and long-term disease prevention.

I've been tracking my food on and off for years, and I've probably downloaded every nutrition app that exists. Some are brilliant. Some are frustrating to use daily. Most are somewhere in between.

But which ones are actually worth your time and money?

The fitness industry has been misinterpreting research for decades, turning nuanced scientific findings into oversimplified rules. Today, we're diving into what the research actually says about doing both cardio and strength training — and why the interference effect might be the most misunderstood concept in fitness.
