The ultimate recipe book for the 'Switch On Diet 4-Week Program'!

A 4-Week Diet Plan to Get You Back to a Healthy, Fat-Free Body

“I lost 10kg of body fat while maintaining my muscle mass”, “I was able to stop taking my blood pressure medication”, “My fatty liver levels returned to normal”, “My blood sugar levels improved”, “My chronic fatigue disappeared”, “My menopausal symptoms were alleviated”… These are the testimonials of people who tried Dr. Yongwoo Park’s Switch On Diet program, which was introduced in “My Body Revolution” and became a huge topic of conversation.
Because it became popular as a challenge, called the '4-week program' or '4-week routine', YouTube and social media are overflowing with reviews and comments about the Switch On Diet.
The age range of practitioners is also diverse, from the MZ generation in their 20s to the elderly in their 70s.
The Switch On Diet is a diet method independently developed by Dr. Yongwoo Park based on his extensive experience in obesity research and clinical treatment. It is a type of 'treatment' program that returns metabolic abnormalities to a healthy normal weight.
This program aims to help you regain a healthy body by correcting your damaged metabolism, and goes beyond simple dieting to transform your body type.
Anyone can experience amazing changes in their body by strictly following the practices for each stage without exception from the first three days to the last four weeks.


When the Switch On Diet dramatically changed the weight that had not been lost despite eating less and exercising, YouTube and social media were flooded with praise and questions from people.
In particular, questions about ‘diet’ and ‘food’ were overwhelmingly numerous.
I've been wondering if my current diet is correct, how much of each food I should eat, and why certain foods are off-limits, so I've published my first recipe book to give you the answers you need.
The book includes a diet guide to follow for weeks 1-4, as well as a variety of diet menus and drink recipes that you can make and eat to your heart's content each week.
We've also included a Q&A page that compiles all of the questions people have about the Switch On Diet, tips on maintaining a healthy lifestyle after the 4-week program, and even a handy appendix with the "Switch On 4-Week Diet Plan at a Glance."
This is a must-read for anyone who wants to eat well and have a healthy diet, or who wants to improve their body's metabolic system and become healthier.

Switch On is really crazy!
We finished the program in week 7, and I lost 12kg and my wife lost 5kg.
I had been increasing my exercise and eating a strict diet, but my weight hadn't budged. Then, I started Switch On and was surprised to lose 6 kg in just the first week.
Now I can eat whatever I want without feeling uneasy and my weight doesn't change, so I'm really happy.
Everyone, start right now.

This is my first time on a diet that's so filling!
I lost 3.2kg on day 8! I even pack lunches and take them with me, and I'm actively recommending it to everyone I know.
We are all studying together, reading books, and dieting together.
It's so much fun and filling.
I found the diet of my life! @Mayo-o6l

Even the doctor who recommended the medicine was surprised
At first, I started with half-belief.
My blood pressure was 149, my fasting blood sugar was 189, and my liver function was also high.
However, after switching on the drug, the blood test results came back surprising to both the doctor who recommended the drug and me who refused it.
After a month and a half, all the values ​​returned to normal.
My weight is still not within the normal range, so I plan to focus on losing weight once more.
Thank you, Doctor! I'm on maintenance right now, so I do something similar to cheat on the weekends.
When warm spring arrives, Switch On begins again! @DreamingWhale-i4z

The most disappointing thing about treating obesity for a long time is that many people are so obsessed with the scale that they intentionally starve themselves or eat less.
Even though we emphasize the importance of eating well, people still can't shake off their doubts, like, "Will I lose weight if I eat like that?"
Dieting that consistently consumes less food will eventually lead to the yo-yo effect because it reduces the resting metabolic rate and causes loss of skeletal muscle.
So, you may experience the side effect of gaining more weight than when you first started dieting.

A body that is suffering from fatty liver, insulin resistance, leptin resistance, chronic inflammation, and carbohydrate addiction shows signs such as weight gain, increased waist circumference, high blood pressure, high blood sugar, and high cholesterol.
Because the symptoms of weight gain occur because the body is damaged and unhealthy, it cannot be treated with a low-calorie diet that simply reduces the amount of food consumed.

I become what I eat.
You need to replenish your body with healthy foods rich in dietary fiber and protein, and burn energy by consuming good carbohydrates and healthy fats.
This way, your damaged metabolism will recover and your body will become healthy.
While diet is important, regular exercise at least four times a week and getting at least seven hours of sleep should also be included in your treatment.

In our busy and tight-knit lives, it's not easy to get regular exercise and get at least 7 hours of sleep a day.
So, let's focus on this for a month.
If you completely cut out forbidden foods, eat plenty of healthy foods, and heal your body with intermittent fasting, exercise, and good sleep, you will be amazed by the results in a month.

You won't see any calories in this book.
A diet that restores a healthy body must include the concept of 'nutrients', which are more important than calories.
You can eat plenty of healthy foods, even if they are high in calories.
On the other hand, foods that are low in calories but not beneficial to your health are not recommended.
In short, you just need to eat healthy foods and avoid foods that are unhealthy.
