Expert opinion

Fitness and sports nutritionist, founder of the Caloriemania healthy lifestyle and nutrition project Ksenia Kukushkina:

– For those who care about their figure or trying to lose weight, eating watermelons is possible and necessary. The watermelon season is not so long as to limit yourself, and then bite your elbows all winter and wait for the next summer. However, do not forget that watermelon is a source of fast carbohydrates that are best consumed in the morning. Be sure to include its energy value in your calculation of the daily requirement of kilocalories.

Benefits of watermelon:

1. 90% consists of water, which means it promotes hydration;

2. despite the large amount of sugar, watermelon contains only 27-38 kcal per 100 g;

3. causes a feeling of satiety, thanks to fiber;

4. contains many vitamins and useful trace elements.

There is even a watermelon diet, but you should not go for such feats. With mono-diets, the body does not receive the macro- and micronutrients it needs. And after spending a fasting day on a watermelon, you can lose 1-2 kg in weight. But it will not be fat, but just water. Therefore, it is better to eat fully and properly, and add watermelon for dessert, instead of cakes and cakes.

Certified nutritionist, member of the public association “Nutritsiologists of Our Country” Irina Kozlachkova:

– Watermelon has many health benefits, one of them is weight loss, as it contains only about 30 kcal per 100 grams. But the low calorie content of this product does not mean that you can eat it in unlimited quantities. The weight of an average watermelon is about 5 kg, and if you eat it at a time, you get the daily rate of all calories. In addition, there are lovers of eating watermelon with bread or muffins, which also leads to weight gain. Also, do not eat watermelon along with pickles, as this causes an excess of fluid in the body and swelling.

The recommended rate of watermelon is no more than 200 grams at a time. This amount does not cause a diuretic effect, so it can be consumed even 1,5-2 hours before bedtime. But if you overeat watermelon at night, going to the toilet several times at night is guaranteed to you, as well as swelling in the morning.

When choosing any diet, contact a specialist to select an individual diet for you, taking into account the characteristics of your health, contraindications, side effects of using a particular product.
