Want to feel full and not gain weight during weight loss? Many people immediately think of cucumber (about 16 kcal per 100g). But a nutritionist points out that there are actually 10 other vegetables with even fewer calories. Eating them in moderation, along with a balanced diet and exercise, is a healthy and satisfying way to manage weight.

Nutritionist Gu Chuan-ling introduces 10 "low-calorie treasures" among vegetables, along with simple and delicious recipes, to help you get enough vitamins, minerals, and dietary fiber while controlling calories:

1. Celtuce / Stem Lettuce (15 kcal/100g)

High in potassium (212 mg) and low in sodium (35.6 mg), helping regulate blood pressure and protect cardiovascular health. Often called a "superfood." Celtuce leaves contain 5.9 times more beta-carotene, 3.3 times more Vitamin C, and higher potassium (305 mg) than the stem. Eat the leaves too!

• Simple Recipe: Chilled Shredded Celtuce with Leaves: Peel and shred the stem, salt for 10 min, squeeze dry. Blanch washed leaves for 1 min. Mix with soy sauce, vinegar, minced garlic, and sesame oil.

2. Bok Choy (Baby Cabbage) / Pak Choi (14 kcal/100g)

Rich in Vitamin C (64 mg) and beta-carotene (889 mcg), with calcium at 117 mg – a "nutritional powerhouse." Vitamin C boosts collagen and iron absorption; beta-carotene protects eyes and fights oxidation.

• Simple Recipe: Bok Choy and Tofu Soup: Cut bok choy into sections and tofu into cubes. Boil water, add tofu for 2-3 min, then bok choy until soft. Season with salt.

3. Tomato (15 kcal/100g)

Lycopene is a powerful antioxidant, better released when cooked; eating raw preserves more Vitamin C. High water content and low calories make it great for replacing vegetables for dietary fiber.

• Simple Recipe: Tomato and Egg Drop Soup: Sauté chopped tomatoes until juicy, add water and boil. Stir in beaten egg, season with salt and sesame oil. Tangy and appetizing.

4. Fresh Kelp (13 kcal/100g)

High potassium (246 mg), low sodium (8.6 mg) for lowering blood pressure. Rich in selenium (strong antioxidant). Dietary fiber increases satiety; iodine suitable for pregnant and breastfeeding women. Eat once weekly.

• Simple Recipe: Chilled Shredded Kelp: Boil kelp shreds, rinse in cold water. Shred radish and cucumber. Mix with soy sauce, vinegar, chili oil, and minced garlic.

5. Celtuce (also known as Asparagus Lettuce – 12 kcal/100g)

Contains potassium (164 mg) and sodium (32 mg), good for replenishing electrolytes post-exercise. Beta-carotene (1634 mcg) protects eyes. Suitable for people with high blood pressure.

• Simple Recipe: Garlic Stir-fried Celtuce: Sauté minced garlic until golden. Add celtuce and stir-fry on high heat for 1 min. Season with salt until tender.

6. Lettuce (12 kcal/100g)

Rich in dietary fiber, increasing satiety and promoting gut motility. High in folate (120 mcg), providing over 1/4 of the daily requirement per 100g. Green leaf and romaine lettuce have more beta-carotene and potassium than iceberg.

• Simple Recipe: Lettuce Wraps: Prepare rice, shredded cooked meat, egg strips, and cucumber strips. Wrap in lettuce leaves and eat.

7. Celery (13 kcal/100g)

Both water celery and common celery are rich in dietary fiber, which binds to cholesterol and glucose, slowing absorption. Apigenin has potential blood pressure-lowering effects. Water celery has 1.7 times more potassium than common celery.
