Eat the same food every single day. Same amount, Same everything. Basically you prepared a meal list that is your calories budget of your target weight. Say 1800 calories. You prep a meal that you actually like to eat, and are willing to eat it every single day. By not having the option to choose something else. You keep it simple, the same calories. If you dont mind eating steak every day, or burger every day. Then Burger it is. Avoid Deep fried food though, but if you do your calculation you will soon realise 1800 calories per day doesn't actually give you much option.
Walking at least 35 min per day. No need to do running. Just walk. Go out, walks some places, window shopping, walk you dog. Whatever, walk. 35 min minimum.
That seems really dangerous because you are dramatically increasing your risk of malnutrition. If there is a nutrient that happens to be somewhat lacking in that one meal, there is nothing to make up for it.
