Sweet potato instead of dinner, actually does not mean that you change the whole dinner into sweet potato, which is ok. If you really want to lose weight, the overall calories must be well controlled. Although the calorie intake may be lower at night, we should also pay attention to the meals in the morning and at noon, otherwise we will still get fat if we eat too much at noon in the morning.
In fact, the most suitable way for sweet potato meal replacement is to replace part of the staple food. If you simply eat sweet potatoes, the intake of nutrition is unbalanced, which can easily lead to long-term malnutrition. You can use coarse grains such as sweet potatoes and corn to match, instead of related staple foods such as steamed bread or rice.
In a word, whether you can lose weight mainly depends on what sweet potato to replace and how much sweet potato to eat. If you eat a lot for dinner like most people, use one or two medium-sized sweet potatoes for dinner, and you can lose weight by eating like this for a long time.
One 130g medium-sized sweet potato has a calorie of about 1 12 calories, containing 2g of protein and 26g of carbohydrates. Ordinary people need at least thousands of calories to eat. If they only eat 1-2 medium-sized sweet potatoes for dinner, they will eat at least 800-900 calories less every day.
But if you don't eat much for dinner and use sweet potatoes instead, you won't eat so many calories and lose weight probably not so fast. If you don't eat much for dinner, you can usually use sweet potato as the staple food at noon, so it is possible to eat less calories.
As for whether eating sweet potatoes for a long time will do harm to the health, it still needs to vary from person to person to a large extent. Most people have no problem eating sweet potatoes for a long time.
However, some people will flatulence after eating sweet potatoes, or some people have different functional bowel diseases. If they feel uncomfortable or have various reactions after eating sweet potatoes, don't eat them like this. It's not what kind of harm sweet potatoes will do to our bodies, but the discomfort of our own stomachs.
Therefore, it is unscientific to lose weight only by dieting. After all, you have to exercise and reduce the fat you eat bit by bit. Control calorie intake, and then cooperate with fitness exercise to consume your own fat, so as to really lose weight.
So you can use sweet potato instead of dinner, but you also need to pay attention to the balance of your own nutrition. It is unscientific to rely solely on dieting to lose weight. Controlling diet and exercise is the best way to lose weight. You can't just eat sweet potatoes. Eating too much may lead to obesity and flatulence in the intestines.
Although sweet potato is a very healthy food, like other healthy foods, it is not suitable for everyone. There are really many ways to lose weight. The key is to eat less, not necessarily by sweet potatoes.
As long as you master the principle of eating less, losing weight is really all roads lead to Rome, otherwise the road will be blocked.
