One common cause of the increasing number of overweight and obese people in the United States is that portion sizes have increased. This means that people are consuming larger amounts of food in one sitting than they did in the past.

To identify this cause, you can look at various data sources and studies that analyze the trends in portion sizes over time. One way to do this is by examining research articles or reports that focus on the topic of portion sizes and their impact on obesity rates. These studies often use surveys and data from food consumption records to compare portion sizes from different time periods.

You can also refer to government statistics or databases that track national trends in food consumption and portion sizes. These sources may provide information on average portion sizes and changes in eating habits over the years.

Additionally, you can analyze data on the availability of large portion sizes in fast-food restaurants, convenience stores, and other food establishments. You may find that the portion sizes offered in these places have grown significantly, contributing to overeating and weight gain.

Overall, by examining research articles, reports, and data sources related to portion sizes, you can identify evidence supporting the claim that larger portion sizes are a common cause of the increasing number of overweight and obese people in the United States.
