Please, you need at least 1000 kilocalories every day to maintain basic metabolism. Even if you don't move much, you will move around at home and don't go out to brush your teeth, wash your face and walk. Two eggs are about 160 kcal, a cucumber is less than 30 kcal, and 7,700 kcal is one kilogram of fat, so you can definitely lose weight. But can you hold on? Even if you can persist, you will be seriously ill and bedridden, which will have a great impact on your health. Take your time.
