Assuming 2000 kcal/day is the normal amount blah blah blah.

For men, they are running a 300 kcal deficit for 5 days and 1500 kcal deficit for the other two. For a total of 4500 kcal per week. Or losing about a pound and a half.

Now, seeing as this is for overweight people, it's likely to be even more. As it takes more calories per day to maintain higher weights. So if the person's maintenance is about 3000 kcal/day, that's going to be a deficit of roughly 11,500 kcal per week. Which is close to 4 pounds.

But then again, restricting yourself to just 2000 kcal/day would have you lose about a pound and a half per week.

Because, when you are very overweight, lots of things work.
