"Prime Cast" opens up. Pat Chayanit Chansangawech. From a severe asthmatic child to a genuine partygoer! She candidly shares every angle, having once followed the extreme health trend of eating only one meal a day to live longer. However, the results were the opposite—thin, worn out, irritable, hair falling out, and no visible fitness gains. She admits life isn’t perfect.
Were you a child who had to carry an oxygen tank to school because of asthma?
Pat Chayanit: Yes, I had asthma. Do you know about Malaysian grass? It's flat with hairs on it. I was severely allergic. The school planted it everywhere, so during breaks when kids ran around, I couldn’t join. If I ran even a little, I had two choices: 1. nosebleed or 2. asthma attack. I had to carry an oxygen tank to school. I wanted to play, but when I had an attack, the caregiver would shake the tank for me. Now I’m cured because they started allergen immunotherapy injections when I was about 10 years old. I was treated from age 10 until grade 7.
Do you still have any allergies today?
Pat Chayanit: Nowadays, I’m allergic to nuts, milk, butter, eggs—basically foods—and still to dust and PM 2.5. Do you understand the concept of hereditary diseases? It’s something that doesn’t go away. So I have to accept it and take antihistamines.
What symptoms occur from the foods you’re allergic to?
Pat Chayanit: It’s common—like acne flare-ups. I still can’t pinpoint what exactly causes hives after eating, but it’s in common foods like milk, butter, nuts, eggs, oats. I can't eat much. But I’m not OCD or overly strict; sometimes I just don’t care. If I eat something on Monday, then from Tuesday to Sunday, I’ll eat clean food. I allow myself one or two cheat days a week, no more.
Are you someone who eats clean food all the time?
Pat Chayanit: All the time, because I have many allergies. If I can bring my own food, I do. If not, I eat whatever's available. I don't want others to fuss over my food, so I always bring or prepare my own.
Because you’re prone to allergies and illness, did that make you take better care of yourself?
Pat Chayanit: Not really. I tend to fix problems after they happen. I handle most things reactively. For longevity, I focus on mental health first. If your mind is well, everything else follows. I eat clean because I naturally don’t like fried, greasy, or creamy foods. When allergic, it’s not a burden to live this way. I exercise not to lose weight but because I enjoy using my energy.
What kind of exercise do you do?
Pat Chayanit: I like indoor cycling and HIIT classes. My friends have started forcing me to do weight training, which I dislike—it's just not my thing.
Have you ever misunderstood anything about health care?
Pat Chayanit: Many misunderstandings, like when I was in high school, I thought sleep was useless and a waste of time. Later in university, I started liking sleep, but my mindset was if I had to choose between partying or sleeping, I’d pick partying.
Then when you entered the entertainment industry, did your perspective change?
Pat Chayanit: I realized there was no time for partying because I had early shoots the next day, so I began living a balanced life. I had a career and aimed for balance. Not long ago, I tried eating only one meal a day after hearing from Japanese people that those over 70 who eat one meal a day are very healthy. But my health check was the same.
What was the downside?
Pat Chayanit: My muscles got weak, I was very thin and unattractive. Looking at myself made me miserable. I became irritable because of hunger, snapping at everyone. I ate nothing all day except black coffee and water, turning into a nervous wreck.
What did your trainer say?
Pat Chayanit: The trainer got discouraged because there were no results. I lost everything. I’m a person who likes using my strength and energy in workouts. I kept doing the same exercise but cut down to one meal a day. Everything was wrong: hair loss, no fitness gains, thin, unattractive, and irritable for almost a year.
What happened on the day you stopped?
Pat Chayanit: I got bored. That’s it. Life had no principles or system—just daydreams about wanting to try and conquer things, pushing forward without reason, principles, or research.
If you had to choose, would you pick partying, sleeping, exercising, or seeing your boyfriend?
Pat Chayanit: I’d pick all of them. I do everything in one day, including work. I've done it before.
How many days a week do you drink?
Pat Chayanit: People don’t count. Maybe more than two days. It’s better not to talk about it because I’ve heard it’s like a curse—if you say you’ll drink lightly today, the opposite happens; if you say heavily, the same. So I don’t talk about it and just go with the flow. On average, 2-4 days a week with some wild nights.
Any tips to cure hangovers so a party girl can still look good?
Pat Chayanit: None.
If you drank the night before, can you work out the next day?
Pat Chayanit: It depends on how I feel. If it’s really bad and I can’t lift my head, I don’t. Someone once told me it could be deadly. My boyfriend always tells me not to exercise after drinking because alcohol separates blood and water in the body, causing dizziness and imbalance.
Does your boyfriend drink too?
Pat Chayanit: No, he doesn’t drink. For him, two glasses is enough. For me, it’s pairing. I’m laid-back, chill, and when I drink, I don’t get angry like some people. I become happy, smile, and relaxed—even if I can’t stand straight. I’m stress-free and chill.
Update on your love life: how did you meet your boyfriend, how long have you been together, who made the first move?
Pat Chayanit: Two years. He made the first move intentionally. He’s a friend of my friend Arin. They’re friends, and he started chatting with me. We talked for quite a while, about 4-6 months on average.
Did you fall head over heels on the first date?
Pat Chayanit: Not on the first date, but on the second, we went bar hopping. He tried to get me to drink. I told him I’m fine with that—I’m not a lightweight. I made it clear from the start that I enjoy drinking, not just for social reasons but because I genuinely like it.
You feel you’ve both been 100% yourselves from the beginning—does that mean there’s no walls or pretense?
Pat Chayanit: Exactly. We’re authentic. I’m not afraid to be myself or worry about how he sees me. No overthinking or pretending.
When you go out, does he follow you?
Pat Chayanit: No. We clearly communicate that this is my world, my lifestyle, and my friends. Also, I don’t go drinking and causing trouble or drama with other men—I just dance with my longtime friends, whom he knows well. I genuinely like drinking but choose my company carefully.
If guys try to flirt with you, do you fight back?
Pat Chayanit: Yes, I fight with all my heart. A long time ago, before my current boyfriend, one guy was okay with it and even said, “You’re cute, but you’re scary when you drink.” Sorry, we met that very first day.
Do you think that’s why you’ve been single for a whole year?
Pat Chayanit: Probably, because not every guy can accept this. Not every guy likes a straightforward, tough, or unconventional woman. Women have standards, and men do too. Don’t think you’re the best or everyone is perfect. Don’t overthink.
Are you like this with your boyfriend?
Pat Chayanit: Exactly like this.
What’s the biggest fight you’ve had?
Pat Chayanit: In two years together, the biggest fight was about choosing between Thai or Chinese food. We rarely argue. I even told him, “I want to argue—can you help me pick a fight about something?” He said that’s the most trivial thing in the world.
Is longevity just an ordinary topic for you?
Pat Chayanit: I love gossip—it’s entertainment and fun. I forget it when I get home. Sometimes I don’t even have personal issues to discuss. Gossip equals longevity because mental health is most important. I prioritize mental health above all. Whatever makes me happy and uplifts my spirit—that is longevity.Some people with good mental health say they balance sleep, diet, mental and physical health, work, and finances. What about you?Pat Chayanit: My mental health is great. Even if something goes wrong or I don’t sleep well, it’s okay. Tomorrow is a new day. If the backstage crew is chaotic, that’s fine—I’ll handle it tomorrow. Maybe others get a bit stressed, but not me.
What else helps your mental health?
Pat Chayanit: I’m very extreme—I party to the fullest and when I want peace, I’m equally extreme in that.
