“Last year it was the one-food diet, this year intermittent fasting, and I signed up for Pilates because it’s trendy…” Do you try a new method every time, but the results are always walking in place? The reason you fail at dieting isn’t because you lack effort, but perhaps because you obsessed over methodologies while ignoring the ‘principles of fat burning’.
Today, I introduce the ‘5 Immutable Laws of Diet Exercise’ that gym trainers unanimously emphasize and that work regardless of the era. If you follow these principles, your body will definitely change.
Law 1. ‘Strength Training’ is Not an Option, It’s Essential (Securing Basal Metabolic Rate)
“I want a slim line, not muscles, so I’ll only do cardio.” This is the most dangerous thought. Muscle is our body’s ‘Energy Incinerator’. To become a constitution that doesn’t gain weight even if you eat the same amount, you must increase your ‘Basal Metabolic Rate (BMR)’, which burns calories just by staying still. The only way to make this possible is through strength training.
- Prevention of Yo-Yo Effect: Weight lost only through cardio and starvation without muscle comes back 100% as a yo-yo effect. You must fill the space where fat left with muscle to create elasticity and form a shield against gaining weight again. Women, please pick up dumbbells with peace of mind; hormones prevent you from getting bulky easily.
Law 2. The Core of Cardio is Not Time, But ‘Heart Rate’
“I walked for an hour while watching a drama.” I’m sorry, but that is not exercise, it is ‘activity’. Fat does not burn in a comfortable state. Only when the heart beats fast enough for the body to feel, “Uh oh? Is this an emergency?” does it start using the stored fat.
- Fat Burn Zone: Fat burns best in the range of 60-70% of your maximum heart rate. It’s an intensity where you can talk to the person next to you but are too breathless to sing.
- Strategy: Stop walking just to kill time. You need to do ‘Real Cardio’ where sweat drips by increasing the incline on the treadmill or speeding up.
Law 3. The Body is a Genius of Adaptation (Principle of Progressive Overload)
After starting exercise, you lose weight well for the first month, but then a time comes when it suddenly stops. Why? Because your body has ‘adapted’ to that exercise intensity.
Our body tries to use energy efficiently for survival. If you exercise with the same weight, same reps, and same speed every day, the body no longer uses much energy.
- Solution: If you did 10 squats yesterday, do 11 today. If you lifted 5kg yesterday, lift 6kg next week. Whether it’s reps, weight, or reducing rest time, you must gradually increase the intensity (Overload) for the body to continue changing. The moment it becomes comfortable, the exercise effect disappears.
Law 4. The Other 23 Hours Are More Important Than the 1 Hour at the Gym (NEAT)
Many people are satisfied with the fact that they exercised for 1 hour at the gym, and then stick to the sofa or chair for the rest of the time without moving. However, the secret of people who lose weight well lies not in the gym, but in ‘Daily Life’.
This is called ‘Non-Exercise Activity Thermogenesis (NEAT)’.
- Taking stairs instead of escalators
- Taking a walk during lunch time
- Diligently doing housework These trivial habits gather to burn an additional 300~500kcal a day. Don’t say “I don’t have time to exercise.” Every moment you move is exercise.
Law 5. There is No Intensity That Beats ‘Consistency’
It is 100 times more effective to do 30 minutes every day than to exercise for 5 hours a day and lie sick for a week. Dieting is not a sprint, it is a marathon.
- Minimum Habit: On days you don’t want to exercise, lower your goal to “Let’s just go take a shower” or “Let’s do just 10 squats.” Once you start, our brain’s desire to finish a task (Work Excitement Theory) will eventually make you exercise. The important thing is not to let go of the string of exercise.
Conclusion: Your Body Does Not Lie
There is no pill in the world that makes you lose weight immediately upon eating, and there is no body shape you can get without effort. But conversely, it is also my body that surely rewards as much as the sweat shed.
The 5 laws introduced today are not special secrets. But sticking to the basics is the fastest shortcut. Start right now, today. Build muscle, make your heart beat, and move more than yesterday. Three months from now, the you in the mirror will be much more beautiful and stronger than you imagine now.
