The best cardio for fat loss isn't whichever burns the most fat during the session — it's whatever keeps you consistent and keeps your total weekly calorie deficit high enough, regardless of whether the fuel during the workout is fat or carbs.

The central argument matches the exercise-physiology consensus: fat loss is driven by total energy balance over the week, not by the fuel-source split during a single session. The video correctly debunks two persistent myths — the low-intensity 'fat-burning zone' and fasted cardio as a fat-loss accelerator — a point matched by the fasted-training literature (controlled trials show a trivial effect on body composition at matched calories, even though in-session fat oxidation is higher fasted). The measurement protocol (two testers, wearable trackers) is informal self-experimentation, not a controlled trial, so the specific per-exercise numbers are illustrative rather than published findings. The overarching message — pick the cardio you'll actually sustain rather than whichever 'burns the most fat' on paper — holds up well against the literature.
