Jeff wants to maintain his weight, so he should consume the same number of calories as he burns eat foods from only one food group decrease his caloric intake so it is lower than his caloric output increase his caloric intake so it is higher than his caloric output

consume the same number of calories as he burns  

Explanation:

If Jeff wants to maintain his weight, the most important thing is that he doesn't give up on healthy habits just because he has achieved the ideal weight. After all, everything that goes can come back. And if the subject is weight loss, the return of fats is proportional to their lack of discipline in eating and irregular exercise. The key to maintaining the ideal weight in this case is to be reeducated, replacing the habits that are harmful to health with actions that contribute to the well-being and proper functioning of the body. In addition, Jeff must maintain an exercise routine that allows him to burn calories, in which case he should consume the same number of calories he burns.

im 100% sure its all of the above.
