What actually causes fat loss (and what's a myth)
Before debating cardio before or after, fasted training or HIIT, there's only one prerequisite: sustainable caloric deficit. Without it, no trick works; with it, almost everything works. The details below optimize — not replace — the basics. Let's bust the 4 myths that destroy student motivation the most.
Myth 1: "Cardio before weights burns more fat"
The order matters little for overall fat loss — what matters is the energy burned and the deficit by the end of the day. But there's a performance detail: doing heavy cardio first drains energy and hurts your lifting. Since muscle preserves your metabolism, the practical recommendation is:
- - Strength training first, cardio after (or in separate sessions) — preserves strength and quality of the weight training session.
Myth 2: "Fasted cardio burns more fat"
Fasted, the body does burn more fat during the exercise, but that doesn't translate into more overall fat loss for the day — the body compensates later. It works if the student enjoys it and tolerates it well; it doesn't outperform fed cardio. Don't push someone who feels unwell.
Weight loss is measured by your daily/weekly balance, not a single session.
Myth 3: "HIIT is always better than LISS"
- - HIIT: burns more in less time and has a slight afterburn effect. Great for those short on time — but it generates a lot of fatigue and hurts recovery if overdone.
- - LISS (light continuous cardio): less taxing, easy to sustain, good for volume of calories burned and cardiovascular health.
- - Best strategy: combine them — 1-2 HIIT sessions/week + LISS the rest of the time. The best cardio is the one your client actually sticks with.
Myth 4: "Weight training doesn't burn fat, only cardio does"
Strength training preserves (and builds) lean mass during a deficit — which keeps the metabolism up and ensures the weight lost is fat, not muscle. It's the foundation; cardio is the extra burn on top. See why tracking matters %BF and measurements it's about more than just the scale.
Practical framework
- 1. Moderate deficit (don't go hungry — an aggressive cut hurts adherence and lean mass).
- 2. Strength training 3-4x/week to preserve muscle.
- 3. Combined cardio (HIIT + LISS) based on time and preference.
- 4. Adequate protein and sleep on track.
