Complete Guide to Fasting for Weight Loss: 5 Key Benefits + 1-Week Meal Plan — Eat Smart, Stay Slim!

The "bigu diet weight loss method" (also known as Bigu, or Daoist-inspired bigu diet) has been trending on Xiaohongshu lately. In this post, we’ll dive into the top 5 benefits of Bigu, plus share a sample 7-day slimming meal plan. Don’t be intimidated by the word “bigu diet”—if done correctly, Bigu can be a safe and effective way to shed unwanted weight and reset your body.

1. What Is Bigu Fasting Diet?

Bigu, or Taoist bigu diet, originated in ancient China as a form of holistic wellness—not originally a weight loss method. Traditionally, it was practiced by Taoist monks as a means to enhance spiritual clarity and energy, drawing “natural qi” from the universe while abstaining from food. Ancient practitioners believed that even without eating, their bodies could remain energized and youthful by tapping into nature’s energy.

In modern times, Bigu has evolved into a popular detox and weight loss technique. Once your body enters a “fasted” state, it switches to burning fat for energy. This means fat is actively metabolized rather than stored, helping you slim down while also easing the load on your internal organs.

2. Is Bigu Fasting Diet the Same as Complete Fasting?

Not quite! Bigu is often mistaken for complete fasting, but the two are quite different. Bigu typically comes in three levels of intensity, and many people only need the beginner level to see noticeable results.

For beginners, Bigu doesn’t require total food restriction. Instead, you consume low-calorie foods and detox beverages. Compare that to more intense bigu diet methods, where people go without solid food for up to three days—those plans are far more demanding and potentially risky.

So, if you're looking for a balanced approach that still delivers weight loss results, Bigu might be the smarter and safer option.

3. Is Bigu Fasting Diet Right for Everyone?

While Bigu can help you drop several pounds in just a few days, it’s not suitable for everyone. Celebrities like Fan Bingbing and Michelle Chen have reportedly used this method to stay in shape, but not all body types are compatible with this form of dieting.

Who should avoid Bigu?

• People with chronic illnesses
• Pregnant women
• Individuals with weak digestion
• Manual laborers or those with physically demanding jobs

Bigu causes your body to lose its main energy source in a short period of time. If your body is already under stress or not in optimal condition, Bigu could worsen your symptoms or lead to fatigue, dizziness, or even illness. And if your work requires physical stamina, bigu diet may leave you drained and unable to keep up with your daily responsibilities.

2. Beyond Weight Loss: 5 Amazing Benefits of Bigu

1. Ancient Wisdom Backed by Modern Science

Bigu dates back to the pre-Qin period and was widely practiced during the Tang Dynasty. Originally, Taoists believed it helped open energy meridians and allowed "positive qi" to enter the body while expelling "negative qi." In today’s terms, that likely refers to improved circulation, lymphatic drainage, and enhanced metabolic function—all crucial for overall wellness.

2. Burns Fat, Not Just Water Weight

Unlike crash diets that mostly dehydrate you, Bigu encourages actual fat metabolism. Some users report losing around one pound per day, and what’s surprising is that the fat loss isn’t just water or muscle—it’s real fat reduction, confirmed through body composition tests.

3. Detoxes the Body Effectively

Many people notice that their waste (urine or stool) has a strong odor during Bigu. This is seen as a sign that toxins are being flushed out. Experts suggest that Bigu helps clear old waste from the gut, improving digestion and eliminating built-up toxins. By returning the body to a cleaner, more natural state, Bigu may even help reset your immune system.

4. Naturally Lowers Blood Sugar

A number of users have reported better blood sugar levels after a period of Bigu, even claiming improvements in prediabetic symptoms. Since your stomach has little to process, internal heat is reduced, easing stress on the liver and pancreas. Over time, this helps regulate glucose metabolism and brings balance to blood sugar levels.

5. Cleanses the Blood and Removes Impurities

Bigu is like a full-body reset button. As your body detoxes, harmful cells and residues—including bad cholesterol—are expelled. Studies show that this method may help clear debris from blood vessel walls, reducing the risk of high blood pressure and poor circulation, while promoting overall cardiovascular health.

2. Are There Risks to the Bigu diet? 5 Hidden Dangers You Might Not Know

1. Loss of Muscle Mass

The bigu diet may not be suitable for those building muscle. Many women pursue fitness for a healthy, sculpted physique—but bigu diet and strength training just don’t go hand in hand. Bigu diet emphasizes reducing physical activity and food intake to reset the body to its original state, while muscle-building requires consistent, intense workouts. What’s more, during the bigu diet process, you’ll lose muscle along with fat, potentially blurring those hard-earned muscle lines and even reverting your body to its pre-toned shape.

2. Poorer Skin Quality

Many women online have shared their bigu diet weight loss journeys, and one common complaint is deteriorating skin condition. A lot of people abandon the bigu diet for this reason, calling it an effort with no reward—a “dumb tax” on beauty. The culprit? Collagen loss. This restrictive eating method causes your body to shed collagen, the key component that keeps skin firm and plump. As a result, bigu diet can lead to dehydration, reduced elasticity, and rough texture. Unfortunately, these skin issues usually only start to improve after your body fully adapts to the bigu diet routine.

3. Risk of Hypoglycemia

Bigu diet drastically reduces food intake, leading to low blood sugar levels. While high blood sugar gets a lot of bad press, low blood sugar is no better—your body needs balance. Hypoglycemia can cause chronic symptoms like dizziness and anemia, and in more severe cases, it may damage brain cells or disrupt the immune system.

4. Weakened Digestive System

A weakened digestive system is another possible side effect of bigu diet. Since bigu diet often involves abrupt changes in eating habits, it essentially “forces” your digestive system to adapt. With less food in your stomach, your intestines slow down, and excess stomach acid may begin to damage the intestinal lining. This disruption of normal digestive rhythms can lead to discomfort and long-term issues.

5. Low Energy and Mental Fatigue

If you’ve tried bigu diet, you may have noticed how much more easily you get tired or distracted. That’s because your body isn’t getting enough food to produce energy. The ancient ideal of being "spiritually full without needing food" is tough to achieve—most people simply can’t maintain normal energy levels without proper fuel.

3. The 3 Stages of Bigu Diet: What You Can and Can’t Eat

1. Reduce Portion Sizes and Swap Staple Foods

Before starting a bigu diet, it’s important to first cut down your overall intake and swap out your usual carb-heavy staples like grains, rice, and noodles. These are often the main culprits behind weight gain. Reducing or completely cutting out these foods can lower your overall calorie intake—a solid starting point for weight loss.

2. Beginner Level

For bigu diet beginners, start by avoiding cooked foods—not raw or cold dishes, but instead switching to a diet of mainly fruits and vegetables for your three daily meals. If you’re not ready to cut out staple foods entirely, small portions of easy-to-digest items like congee or thin noodles are okay. This stage is all about conditioning your stomach to get used to eating less.

3. Intermediate Level

At the intermediate level, you’ll need to stick more strictly to bigu diet. Cut out all staple foods completely and rely on water or honey water for meals. If hunger becomes overwhelming, you can have small amounts of fruit, nuts, or red dates. The goal is just to stave off hunger—not to overeat, or all your efforts will go to waste.

4. Advanced Level

At this stage, no solid food is allowed. You’ll consume only liquids to feel full—juices, detox water, herbal teas, or even coffee, depending on your preference. This is the most restrictive form of bigu diet.

4. Bigu Fasting Like a Celebrity: The Diet Plans of Fan Bingbing & Michelle Chen

Fan Bingbing’s Bigu Diet Plan

Fan Bingbing has her own unique method: for the first three days, she drinks one cup each of apple cider vinegar and lemon-passion fruit water. For the following four days, she switches to dendrobium and red date water, while walking 5 to 6 km daily. With this routine, she lost 6kg in a single week!

However, she emphasizes that this extreme regimen was driven by her job requirements and shouldn’t be blindly copied. For beginners, she recommends trying intermittent bigu diets for just 1 to 2 days, then gradually increasing your intake after 3 days. Never go completely food-free!
