In principle, yes, it is possible, but it will be much more difficult than losing weight through sports.
You will start losing weight when you burn more in a day calories than you consume . When you exercise, it is much easier to burn calories, which means that you do not have to significantly reduce the amount of food you eat, remove a lot of foods from it, choose only very low-calorie foods, etc.
If you exercise sports at least 3 times a week, you will be able to more variety of products .
If sports are not yours, then I advise:
Losing weight is primarily a calorie deficit. The body does not care how you got the same deficit. Whether it is cutting calories or daily efforts in the gym. However, do not forget the main nuance of losing weight without much effort, namely by simple cuts in calories: without sports, your body will more likely resemble a floating jelly than a fit and beautiful figure
Maybe. You just need to follow the diet and count calories - get them from food less than the body burns. On the Internet you will find calculators for calculating the calorie content of dishes and the consumption of kcal. (Source: personal experience - minus 30 kg. With a sedentary lifestyle and complete absence of sports.)
It is important to understand that in the 21st century, the only way to lose weight is either diet or burning calories> than you consume them. If you don't want to exercise, choose your diet on the Internet or consult a nutritionist.
