So your first task is to control your diet and give you a recipe.
Breakfast: a bag of skim milk +2 eggs +3 slices of whole wheat bread (30g each) +20g honey, 10 a fruit (almost the weight of an apple), lunch: 150g cooked rice+boiled vegetable leaves+2 strips of steamed fish, and a fruit at 3pm. Dinner: 120g rice+boiled vegetable leaves, and a bag of milk before going to bed. Honey and cereal are sold in the supermarket, which is very cheap. Honey also has a very good cosmetic effect. In addition, be sure to eat enough staple food. If you don't eat staple food, the stomach and intestines will decompose nutrients such as vegetables and protein into energy, and its metabolites are very harmful to the body. This is how you get colon cancer. You must eat staple food. If you are hungry, just bear it. Don't increase your appetite as long as it doesn't affect your work. Eating an apple is really not good. You should know that hunger and physical needs are two different things.
You may say that you can't boil leaves with water for every meal, and that's okay. Just put a glass of water in front of you and rinse the greasy dishes with water before eating. You know, meat, eggs, milk and protein won't make people fat. What really makes people fat is too much calories, fat and grease, so the first thing to lose weight is to control oil. You may also ask how much is 100g rice? There is no way out. Go to Taobao to buy an electronic scale. Not to 50 yuan. Since you want to be thin so much, you still need to work hard.
Don't eat anything except the top bite, plus running at 6k every day, the fat will soon disappear and the weight can be reduced to at least 65kg.
Nothing else. Remember to control your diet. Exercise is only an auxiliary means. The rest is to let your body burn the fat in your body. Don't weigh yourself recently, give your body some time, 1 month and see if there are any surprises.
