This is a tricky question to answer. The short answer is that there is no such duration. That is, it is generally accepted that genuine weight loss in a typical week maxes out between 1 and 2 lbs. Any weight lost above 2 lbs can be attributed to water loss, and excessive water-weight loss can easily cause dehydration.

Now, if you just want math...
A 150 lb male burns approximately 100 calories per mile running. It takes a calorie deficit of 3500 calories to burn a pound. So, to burn 7 lbs would require a deficit of 3500 calories/lb x 7 lbs = 24,500 calories.
Therefore, to burn 7 lbs, our intrepid runner would have to run 245 miles per week (24,500 calories / 100 (calories / mile)). Assuming that our runner can run a 10 minute mile for all 245 miles, he would have to run for 2450 minutes per week (or 40 hours, 50 minutes).

But, again, totally unsafe and unrecommended.
You cannot lose 7 pounds of body weight each day.
It is pysically impossible to lose 7 pounds in a week.

7 pounds of fat
When a person dies, they lose approximately 7 pounds due to the release of bodily fluids and gases, as well as the relaxation of muscles.
If you weigh 215 pounds and fast for 7 days then you would lose several pounds. However, you would most likely regain weight once you started eating normally again. If you want to lose weight and keep it off, you need to exercise, change your eating habits on a long-term basis, and lose weight slowly and steadily.
Here are some examples: If you are male and need to lose more than 30 pounds, you can plan on around 10 or more pounds in the first 7 days. I have seen men lose as much as 12. If you need to lose around 15 pounds, you can plan on losing about 7 pounds the first week. If you are a woman and need to lose around 60 pounds, you can most likely plan on losing 12 pounds the first week. If you need to lose about 30 or less pounds you will most likely lose around 5 to 7 pounds the first week. The above situations are based on doing the HCG Diet correctly!
It's impossible to lose 20 pounds in overnight. Nutritionists are always recommending 2 pounds of weight loss in 7 days, according these levels it is always recommended to lose 20 pounds in 10 weeks.
Stop eating? NOT recommended!
