20 % of resting energy goes to the 1.4 kg blob between your ears—same as a 20-W LED bulb left on 24/7.
Mental gymnastics (Sudoku, chess) raise cortical glucose uptake 5-8 %, but no, it’s not a fat-burner—so keep the actual burpees.
Pro tip: combine learning with light cycling; University of Graz research shows 15 % better memory retention.

2. The Power of Sleep: More Than Just Rest 😴

One all-nighter = 30 % rise in ghrelin and 24 h craving for 500 extra kcal (University of Chicago).

Weight	0.55 kg	0.45 kg
Caloric burn/day	7-10 kcal	2-3 kcal
Space occupied	18 % less	—

Take-home: swap 5 lb fat for muscle → jeans fit looser, scale may stay put, but BMR rises ~50 kcal/day.

5. The “Afterburn Effect”: EPOC Explained 🔥

Vigorous 45-min cycling can burn 420 kcal during, plus 14 % bonus (≈60 kcal) over next 14 h.

Type	Duration	Best for
Static	30-60 s	Post-workout, cool-down
Dynamic	10 reps	Pre-workout, neural priming
PNF	6 s contract + 10 s stretch	Rapid ROM gains

Mobility = usable ROM under control; flexibility = passive ROM. Train both.

🚫 Busting the Bunk: Debunking Popular Health & Fitness Myths

Myth 1: “No Pain, No Gain” 🤕

❌ Reality: pain = injury warning. DOMS ≠ sharp pain. Use RPE scale; stop at 8/10.

Myth 2: “Carbs Make You Fat” 🍞

❌ Reality: excess calories do. Whole-grain carbs aid thyroid → metabolic health.
Exception: refined sugars spike then crash hunger.

Myth 3: “You Can Target Fat Loss” 🎯

❌ Reality: fat loss is systemic; genes decide where it melts first. Combine deficit + full-body resistance.

Myth 4: “Sweating More Means Burning More Fat” 💦

❌ Reality: sweat = thermoregulation; sauna suits only drop water weight. Fat oxidation measured via gas exchange, not puddles.

Myth 5: “Only Intense Workouts Count” ⏱️

❌ Reality: walking 30 min/day lowers CVD 19 %. Any movement > none—WHO mantra.
