option is E) 8 to 10  pounds per week can be lose

The above examples and a little math confirm you certainly can lose a lot more. If you start at a weight of 250, cut back to 500 to 800 calories, and work out for two hours daily,  you could expect to drop seven to nine pounds a week, says obesity expert Yoni Freedhoff, M.D., author of the forthcoming book Why Diets Fail and How to Make Yours Work.Most experts recommend that you lose roughly one to two pounds per week,  even though you may not consistently lose two pounds every week, while you can easily lose 10 ponds in a week but not pure fat as it's  a little hard but with that you will also drop pounds by losing excess water weight.

the most common energy conversion is from kinetic energy to potential energy, and then from potential energy to kinetic energy.

later on comes the heat energy, mechanical energy, and other energy conversions.

this energy conversion is so common that we can find it in our day to day lives as well.

- one of the most common energy conversions involves the changing of potential energy to kinetic energy or kinetic energy to potential energy
