Roberto addresses this new information "by acknowledging that some people disagree with his position"
Roberto cannot ignore the new source or call it foolish but can only acknowledge it and then finds better reasons to support his own claims above what the new information says.
1.) Lack of motivation which could be from not seeing any results or just not feeling like it.
2.) Not sure of what exercises to do or what diet plan to go with.
3.) Might not be able to afford a gym membership or healthier food.
