I’m 166 cm and 48.9 kg, but I don’t look slim at all—maybe because of my straight body type.

From your papa’s perspective, you’d look best if you gained another 2 kilos or so. At least gain another kilo, even if that’s all. You’re already too thin for your health as it is. Losing even more would be worse.

At 166 cm and 48.9 kg, your BMI is under 18, so I’d say you’re already more than slim enough. Do you know that a BMI below 18.5 is associated with the shortest average life expectancy—shorter even than obesity? As Makéotoko also points out, I’d advise you to exercise and build some muscle. I wish the papas they’re seeing would think more carefully about their partners and offer advice accordingly.

I’m 166 cm tall and weigh 48.9 kg. But maybe because I have a straight body type, I don’t look slim at all. ☆Sometimes having a larger bone structure can keep you from looking petite. I also have a broad frame, so I can’t look delicate either. It’s sad, isn’t it? I eat two meals a day… I’ve lost 3 kg in two months, so I’m not dieting in an unhealthy way. ☆Do you eat breakfast and lunch? Do you know when to drink protein? If you naturally have a larger bone structure, you’re probably close to your limit already. Your period may stop, too. Please stop dieting with an excessive focus on your weight. I think it’s enough if you look toned. Please don’t let your weight control you anymore. ☆Papa… I want to tell him, “Why don’t you lose weight yourself? You’ve got such a flabby body.” I also want to ask him, “What are you going to do if the questioner develops mental health problems?”

Please go to a service like RIZAP and consult with them.

Your goal is to “become an attractive woman and be popular,” right? Or am I mistaken? Since dieting is just a means to that end, I felt like you might be headed slightly in the wrong direction, so I thought I’d answer. If it were me, I’d advise: “Get down to 50 kg by doing strength training and running to lose fat and build muscle.” That’s because it’s obvious you’ll become far more attractive that way. *Muscle weighs more than fat.* No matter how thin you get, without any muscle you’ll look frail and completely unattractive—just skinny. Only eat breakfast and dinner, twelve hours apart. If you start feeling dizzy around lunchtime, suck on some dark chocolate to raise your blood sugar. The best time for strength training is in the morning. In particular, doing squats in the morning makes your body more prone to losing weight. There’s no evidence for this, but it’s something bodybuilders know from experience. The model Rola is 165 cm tall and weighs 49.7 kg. She’s 1 cm shorter than you, yet actually weighs more, right? And look at her figure. Do strength training and aim to look like Rola. If you just lose weight, you’ll be heading straight toward being unpopular. I want to be ridiculously popular, so I do an hour of strength training every morning. I usually run during the day, but basically I run every day. If I don’t run, my heart rate doesn’t get strong enough and I can’t keep up continuous movement from the hips, so I don’t just jog lazily—I run while huffing and puffing. No matter how sexually driven a papa-katsu girl might be, I’m absolutely confident I could keep up with her.

You already seem quite slim, though… Maybe your clothes make you look different than you really are. I’ve never really paid attention to my body type, but I think I might have a “wave” body type. It’s kind of sad that only my upper body is thin. At first glance I look slim, but once I take my clothes off, not so much. If I were going to lose weight, I’d probably try that eight-hour diet—the one that was popular a while back, where you finish all your meals within an eight-hour window. When I tried it, I lost a little weight without much difficulty. There’s a limit to how far that can take you, though, so when I wanted to lose weight quickly, I used to avoid solid food for a week—about five years ago. If I did that now, I’d probably just look older, so I’d increase my exercise instead. Also, I think simply looking at yourself in the mirror every day wearing as little as possible can make a difference. Take it easy and do your best!
