You will need to calculate how much exercise you need to do to lose 10 pounds a week. Calorie ranges lower than 1200 to 1400 calories per day don't burn more weight off, they send your metabolism into a tailspin.
10 pounds is 35,000 calories of fat. If you burn 100 calories for every mile you walk you will need to walk 350 miles a week or 50 miles a day. I'm sorry that sounds ridiculous but that is the way the math works out for someone who weighs about 175 pounds.
In the early weeks of your diet you may be able to lose 10 pounds in the first week as your muscle glycogen stores are burned up. Glycogen binds itself with a lot of Water for use in the muscles and when you quit eating carbs your muscles and brain burn up this fuel alongside fat.
