First, what's wrong with sitting at work every day? First of all, if you consider health and don't consider losing weight, don't sit for a long time. In fact, sitting in the office for a long time is inevitable, but what we can avoid is getting up every hour to exercise, and then going to the window to get some fresh air. It is good for your health.

Secondly, you just said that to lose weight, exercise and diet are the most effective ways to lose weight. Then if you don't want to exercise, eat something above and below. For example, when eating, try to eat low-fat and low-calorie foods, or foods with less oil, salt and sugar. For example, when we get up in the morning, we will eat some oatmeal. Or drink a glass of milk, add a piece of bread and an egg, and you don't have to eat some greasy and salty food like beef noodles. You can consider a normal diet at noon. In the evening, we may just eat some whole grains and then eat a fruit. Here, let's focus on oats. Oats are low in calories but high in satiety, so it is recommended to eat them often.
