If the whole World had U.S average weight

If every country in the world had the same weight distribution as in the U.S., it would mean an increase in biomass of 20%. Or expressed more simple If the whole world had the same weight distribution as in the U.S., it would mean a body mass equivalent to an additional 1 billion people with a normal BMI.

Large parts of the world is moving in the same direction as the United States. If it becomes real, we will erode hard on the earth's food and nutrition resources, although the total amount of people possibly will decrease.
