Drink a cup of boiled water after getting up in the morning, eat 10 piece of spirulina, then eat an egg and a bag of milk.
Vegetables and white meat (chicken, fish or shrimp) are suitable for lunch (the amount of a dish, a chicken leg or a chicken wing).
At night 10 slices of spirulina and raw vegetables such as cucumber or tomato can be eaten raw, with a bag of milk before going to bed.
Seasonal fruits can be added between meals.
After dinner (1-2 hours), do some aerobic exercise, find something about slimming from the internet, and do 9 movements, 20 times each, and stick to it every day. Believe me, losing weight like this won't hurt your health, and you can lose weight healthily!
Because you are an office worker, you can't stand being hungry, so you can increase the dosage of spirulina by 20-30. Remember that spirulina must be eaten before meals, and it will get fat after meals.
