Losing weight is not just about eating less. The important thing is to choose the right foods so that your body still gets enough nutrients, stays full for a long time and limits fat storage. A smart diet helps you reduce calories while still feeling satisfied, not hungry, not tired and without having to go on a strict diet.
How to eat the right foods when losing weight?
Here are some scientific, easy-to-apply eating principles that will help you improve your weight in a healthy and sustainable way:
1. Eat lots of fresh fruits and vegetables every day
Fruits and vegetables contain lots of vitamins, minerals and fiber but very few empty calories. This helps you eat enough without worrying about consuming too much energy. You can add vegetables to familiar dishes to increase nutrition without adding too many calories.
For example, blend cauliflower, carrots or pumpkin into pasta or porridge; it will add “volume” to the dish and help you feel full longer.
Tip: Find ways to “color” your meals. The more colors from fruits and vegetables, the more nutritious and attractive the meal will be.
2. Add foods rich in fiber
Fiber helps slow digestion, keeps the stomach full longer and limits snack cravings. Beans are a great choice because they are rich in fiber and contain a lot of vegetable protein. When the body is provided with enough protein and digests more slowly, you will eat less and still feel comfortable.
3. Limit juice, eat whole fruit
Fruit juice, even fresh juice, can contain more sugar and calories than you think. Meanwhile, eating whole fruit helps you get enough fiber and creates a feeling of fullness for longer. When you have to chew, the body also sends a faster signal to the brain that you have eaten enough, thereby limiting overeating.
4. Choose foods that contain a lot of water
Water-rich foods such as cucumbers, watermelon, zucchini, strawberries, lettuce, etc. help you feel full for a long time without consuming many calories. Adding them to your meals or eating them before your main meals will help you reduce your intake naturally without having to force yourself to “abstain”.
However, with fruits, pay attention to the amount of natural sugar in some types such as grapes, mangoes or durian.

5. Eat foods that support metabolism
Some natural foods can help the fat burning process take place more effectively. For example:
- Green tea
- Hot peppers
- Berries
- Whole grains
On the contrary, you should limit processed foods and foods high in sugar because they cause insulin to increase, leading to more fat storage than fat burning.
6. Add good fats
Unsaturated fats such as those found in avocados, olive oil, nuts, flaxseeds, etc. have been shown to help the body metabolize better, even helping to reduce belly fat. Replacing animal fats with good fats is a simple change but has a clear effect on health.
7. Eat superfoods wisely
“Superfoods” are not all miracle foods, but some are really nutritious. For example:
Quinoa is a complete protein source, contains enough amino acids, is rich in magnesium, iron, calcium and many nutrients compared to most other grains.
However, learn before choosing and do not rely too much on any one food.
8. Avoid foods containing “empty calories”
Empty calories are calories from sugar and fat but provide almost no nutritional value. Popular options include:
- Sweets, cakes, biscuits
- Soft drinks
- Bottled energy drinks
- Pizza, fatty cheeses
- Ice cream, cold cuts and fatty sausages
If you still want to enjoy these foods, choose small portions – this will help you maintain your diet without feeling “forbidden”.
9. Eat more soup
Soups are low in calories but help you feel full faster. If you start a meal with a bowl of clear soup, you will often eat less of the following dishes. Choose soups with water, 100–150 kcal/portion, avoid soups with added cream.
10. Allow yourself to eat your favorite food occasionally
No one can diet perfectly forever. The culture of “absolute prohibition” often makes us fail and overeat later. If you crave pizza, donuts or ice cream, allow yourself a little, but in moderation. It’s not a failure, it’s part of a healthy and flexible eating lifestyle.
In short, effective weight loss is not necessarily about eating less, but eating right. When your body is provided with enough fiber, vitamins, water and good fats, you will automatically eat less without feeling deprived or tired. Start with small, easy-to-do changes and maintain them every day. From there, your body will be healthier, your weight will gradually improve naturally and sustainably.
