Jamie is reviewing a new diet plan that involves purchasing pre-packaged meals and taking a patented energy supplement. In an ad explaining how it works, Jamie reads about a study cited as evidence supporting the effectiveness of the plan. In the study, two groups were followed: one following the plan and another following a simple low-carbohydrate diet. What should Jamie look for in the study to have full confidence in its scientific reliability?

Jamie should look at the difference in results in the two groups of people.

Explanation:

According to the question, two groups are being studied in which the one group is taking the food according to the new diet plan and the other group is taking a simple low-carbohydrate diet. So, for having full confidence in its scientific reliability, Jamie should look that the people taking pre-packaged meals as per the new diet plan are getting better results or not than the people who are taking low carbohydrate diet. If she gets a result in which it is found that new diet plan is giving a positive health benefit to the people then this new plan is scientifically reliable.
