My Personal Journey with Carb Restriction
For those of us who have been navigating the world of diet trends for years, blood sugar control may feel like a new label for an old concept—but it works.
About 5 to 6 years ago, I first discovered the power of carbohydrate restriction through a ketogenic diet. I limited my daily carb intake to just 50g (about 1.76 oz), and in just two months, I lost nearly 10kg (around 22 lbs).
As a woman around 160 cm tall (5'3"), the transformation was significant. I've currently been consistently maintaining my weight between 52-54 kg (114.6-119.0 lbs).
Back then, keto was hardly mainstream in Korea. Zero-sugar alternatives were rare, so I often had to cook everything myself from scratch. But times have changed.
Today, the blood sugar control diet has exploded in popularity across Korea. Supermarkets and convenience stores now offer a growing selection of zero-sugar drinks, snacks, and even low-carb bakery items—making the diet far more accessible than ever before.
How It Works: The Science Behind Blood Sugar Control
To understand why a blood sugar control diet works, it’s important to know what happens in your body after you eat carbohydrates.
- Insulin & Glucose: When you consume carbs, your body breaks them down into glucose, which enters the bloodstream. In response, your pancreas releases insulin to help shuttle this glucose into cells.
- Spikes Lead to Resistance: Over time, eating too many sugary or high-GI foods leads to repeated blood sugar spikes. This can cause insulin resistance, where your cells stop responding properly, demanding more and more insulin.
- Consequences:
- Fat Storage Increases: Excess insulin promotes abdominal fat storage and blocks fat breakdown.
- Crashes & Cravings: Sharp drops in blood sugar post-meal lead to fatigue, irritability, and sugar cravings.
- Metabolic Slowdown: Insulin resistance is associated with slower metabolism, inflammation, and type 2 diabetes.
In short: Stable blood sugar = stable insulin = easier fat loss and better overall health.
Step-by-Step Guide: From Beginner to Intermediate
✅Beginner: Start Simple with Everyday Habits
1. Reverse Eating Order
Known in Korea as ‘거꾸로 식사법 (geokkuro siksa-beop)’, this method involves eating vegetables first, then protein, and ending with carbs. This slows the glucose absorption and leads to a lower blood sugar response.
2. Post-Meal Walks
A 10-minute light walk after meals can reduce blood sugar spikes by up to 22% (according to a 2022 study in Sports Medicine).
Even indoor walking or pacing works!
✅Intermediate: Taking Control
1. Limit Refined Carbs and Sugary Foods
- White bread, rice cakes, noodles
- Sugary drinks, sweetened coffee, flavored yogurt
- Processed snacks like chips and cookies
- Sweet sauces like teriyaki and ketchup
Try to keep your total carbohydrate intake under 100g per day (about 3.5 oz), or lower depending on your personal goals.
2. Use a Continuous Glucose Monitor (CGM)
Devices like Freestyle Libre and Abbott Libre Sense are now more widely available in Korea. A CGM lets you monitor blood sugar in real-time, helping you identify which foods work for your body—and which don’t.
Final Thoughts
When I first tried carbohydrate restriction, I stuck to a strict 50g per day limit—and it worked. But that might not be necessary for everyone. If you're considering this diet, start small and observe how your body responds. Don’t blindly copy influencers or meal plans. Your body and metabolism are unique.
Thanks to Korea’s growing market for zero-sugar products, low-carb bakeries, and digital glucose tools, this approach is more accessible than ever.
If you've struggled with other diets and haven’t seen long-term results, the blood sugar control diet may be the missing piece. By keeping glucose steady and minimizing insulin spikes, you support both weight loss and metabolic balance. Start small, stay consistent, and your body will thank you.
