I am Dr. Sun Zhongwei, Ph.D. in Sports Science from Tsinghua University and a senior sports nutritionist, specializing in blood sugar control and muscle building for 12 years.
Jia Ling lost 100 jin (50 kg), and the entire internet erupted.
But as a sports nutritionist who has studied blood sugar control and muscle building for 12 years, I want to remind fellow diabetics: Do not blindly imitate; first, understand the essential difference between muscle building and weight loss.
Jia Ling's Subtraction Method: Not a Direct Blueprint for Diabetics
Jia Ling's weight loss plan is a typical Hollywood-style transformation: extreme calorie deficit, high-volume aerobic exercise, and round-the-clock professional team support.
Result: Body weight dropped by 100 jin (50 kg), but with significant muscle loss.
For ordinary people and celebrities, this might be considered a "success." But for diabetes patients, this is a danger signal.
Why Can't Diabetics Just "Lose Weight"?
1. Muscle is the Most Valuable Asset for Diabetics
Skeletal muscle is the body's largest glucose metabolism organ.
- During muscle contraction, the GLUT4 transporter is activated, allowing insulin-independent glucose uptake from the blood.
- Each additional kilogram of muscle increases daily calorie expenditure by approximately 13 kcal, continuously improving metabolism.
- Muscle secretes myokines like IL-6, which can improve whole-body insulin sensitivity.
The core issue for diabetics is not obesity, but low muscle mass combined with insulin resistance.
2. Extreme Weight Loss = Accelerated Muscle Loss
Studies show that extreme low-calorie diets combined with high-volume aerobic exercise result in more than 30% of weight loss being muscle.
For diabetics, this means a further decline in blood sugar control ability, a lower basal metabolic rate, and an increased risk of sarcopenia.
3. The Correct Sequence for Diabetics: Preserve Muscle First, Then Reduce Fat
| Phase | Goal | Method |
|---|---|---|
| Phase 1 | Preserve Muscle | Resistance training + Adequate protein (1.2-1.6 g/kg) |
| Phase 2 | Reduce Visceral Fat | Low-carb diet + Intermittent fasting |
| Phase 3 | Nutrient Timing Management | Post-meal exercise, Protein distribution |
Three-Dimensional Reversal Perspective: Muscle Building × Liver Nourishment × Pancreas Regulation
The three-dimensional reversal theory I propose is specifically designed to address the unique needs of diabetics:
Muscle Building Dimension: Using ACSM-standard resistance training protocols to maximize muscle preservation or even muscle gain while losing fat.
Liver Nourishment Dimension: The liver is the master regulator of glucose metabolism. Extreme weight loss can disrupt hepatic gluconeogenesis, paradoxically worsening fasting hyperglycemia.
Pancreas Regulation Dimension: Through nutrient timing management (e.g., post-meal exercise), reduce insulin demand, giving the β-cells a "break."
Practical Advice for Diabetics
Exercise Protocol (ACSM Standards)
Resistance Training (Priority, 2-3 times per week)
- Compound movements like squats, deadlifts, and overhead presses for large muscle groups
- Intensity: 60-80% 1RM, 8-12 reps per set
- Benefits: Muscle building + Blood sugar lowering + Improved insulin sensitivity
Aerobic Exercise (Auxiliary, 150 minutes per week)
- Brisk walking, swimming, cycling
- Moderate intensity, performed 1 hour post-meal
Dietary Principles
- Protein: 1.2-1.6 g per kg of body weight, distributed across meals
- Carbohydrates: Choose low-GI sources, consume primarily post-exercise
- Fats: High-quality fats (deep-sea fish, nuts, olive oil) to support hormone synthesis
Monitoring Indicators
Don't just focus on body weight; track: Body fat percentage (especially visceral fat), Muscle mass, Fasting and post-meal blood glucose, and C-peptide.
Nuogongzi Three-Dimensional Reversal: A Diabetic-Friendly Version of Jia Ling's Transformation
The Nuogongzi Three-Dimensional Reversal mini-program I created provides diabetics with a personalized "muscle-preserving and fat-reducing" plan.
Core features: Take photos to log your diet, AI automatically analyzes nutritional composition; generates daily exercise and diet plans based on the three-dimensional reversal theory; tracks muscle mass, body fat percentage, and blood glucose trends; community support with professional instructor feedback.
Pricing: 365 RMB/year, includes a 7-day free trial.
Summary
Jia Ling's 100-jin weight loss is a triumph of willpower, but it is not necessarily a model for diabetics.
The goal for diabetics is not simply to be "thin," but to: Preserve muscle, reduce visceral fat, stabilize blood glucose, and improve insulin sensitivity.
This requires a Muscle Building × Liver Nourishment × Pancreas Regulation three-dimensional reversal approach, not just a simple calorie subtraction.
