How long does it take to lose 7 pounds?

Answer 1

Starving yourself really isn't a sensible option. It'll be uncomfortable, unhealthy and not particularly effective. Going on a real strict diet will cause your body to slow right down, making it even harder to lose weight. On top of that, going on a crash diet makes it real easy to put the pounds right back on when you return to sensible eating habits.

You're better off aiming for a healthier and less strict diet, which together with some exercise will let you lose 1-3 lbs/week.

Cut down on sodas, snacks and everything deep fried, and you can lose those pounds in a healthy manner in 3-4 weeks.

Answer 2

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.

Answer 3

If you saw through the elbow, probably about 5 minutes, depending on your threshold for pain and the availability of sedation.

Answer 4

Its not all about the exercise. You need to maintain a negative caloric balance which means watching what you eat too. Negative 3500 calories is equivalent to one pound of body fat lost.
