Their fat levels soar! Even though "eating vegetarian" should be really good for the body. The cause is not because they eat vegetarian food incorrectly, but because they "choose the wrong food", causing the body to receive too much carbohydrate and fat, especially during times when the proportions or quality of vegetarian food are not properly controlled. In this article, a team of doctors W9 Wellness Center Will come to recommend a guideline “Control fat during the vegetarian diet” With simple, practical nutritional principles, it helps you Jay gets merit, good health and a strong heart at the same time. With in-depth health screening guidelines to prevent fat accumulation that may be a risk for heart disease in the long term.
Why is it risky to gain fat and weight during the “Vegetarian” period?
Many people think that vegetarian food is always safe, but in reality, many vegetarian foods are full of
- Simple carbohydrates Such as vegetarian noodles, white rice, vegetarian fried foods
- Processed protein Such as vegetarian pork and vegetarian chicken, which are made from high flour and sodium.
- Hidden oils and sugars In stir-fries, fried foods, or vegetarian desserts
Eating this type of food continuously for 7-10 days may cause blood fat levels, especially Bad cholesterol (LDL-C) and triglycerides In addition, a lack of good quality protein can also slow down your metabolism and make you feel hungry more often.
Nutritional principles: “Vegetarian but not high in fat”
To effectively control fat during the vegetarian diet, the W9 Wellness medical team recommends 5 nutritional principles that everyone can apply in their daily lives.
1. Choose high-quality plant protein.
Protein is an important nutrient that helps maintain muscle mass and increase metabolic rate. Plant-based foods that are high in protein include tofu, tempeh, chickpeas, soybeans, black beans, and quinoa.
avoid “Vegetarian pork” or “vegetarian chicken” because they often contain high amounts of flour and sodium.
2. Use complex carbohydrates.
choose Brown rice, riceberry, sweet potato, oats Because it is rich in dietary fiber and provides more stable energy than simple carbohydrates such as white rice or noodles.
3. Add vegetables to half your plate at every meal.
Colorful vegetables provide fiber, vitamins, and antioxidants, which keeps you feeling full longer and reduces overall energy expenditure.
- Green leafy vegetables: Kale, spinach, broccoli
- Orange–yellow vegetables: Pumpkin, carrots, bell peppers
- Purple vegetables: Eggplant, purple cabbage
- Cruciferous family: cauliflower cabbage
- Aromatic vegetables: Basil, coriander, spring onions
4. Eat mainly good fats.
Good fats from nature such as Avocado, almonds, flaxseeds, olive oil
avoid Fried vegetarian food or reheated palm oil
5. Control salty and sweet tastes.
Ready-to-eat vegan foods are often higher in sodium and sugar than usual. It's better to read labels or cook your own food to be safe.
Example of a healthy vegetarian menu for 1 day (~1,600–1,800 kcal)

Health tips
- Drink at least 2–2.5 liters of water per day.
- Avoid sugary drinks and regular iced tea.
- Walk or do light exercise for 15–20 minutes after a meal.
- If weight loss doesn't occur within the first 2 weeks, try reducing your carb portion by 10–15g.
If you are eating vegetarian but your cholesterol is still high, what additional tests should you do?
In some cases, even though you control your diet and exercise well, your body still tends to have high blood fat or you feel like you're not burning as well as before. This may be caused by: Hormonal imbalance or Metabolism that is not working at full capacity
Additional tests to help you understand your body more deeply
- Advanced Lipid Profile: A comprehensive lipid test assesses the types of fat, such as small dense LDL (sdLDL), that directly affect blood vessels, helping doctors plan more targeted care and prevention of heart disease.
- Hormone Balance Test: Check levels of key hormones such as estrogen, testosterone, and cortisol to monitor your metabolism, stress, and energy levels, which affect your fat and weight levels.
- Urine Organic Acid Test : Urine metabolism test to assess the functioning of cells and the body's energy system. Suitable for people who, despite controlling their diet, still feel tired easily or whose fat is not decreasing.
Data from the Journal of Clinical Endocrinology & Metabolism (2023) suggests that hormone and metabolic balance testing can help with more personalized nutritional planning and behavior modification.
