Only way is caloric restriction. Exercise that builds muscle increases your body’s caloric expenditure, exercise that burns calories raises the number of calories you can eat that day, doing neither means you need to have a more restricted caloric intake.

Personally, I try to focus on weight training and maintaining or slightly losing weight. So far, it’s had quite a positive impact functionally, and aesthetically in my personal opinion (and my partner’s). That being said, I’ve done pure restriction before, it worked in the short term but I gained most of it back, and I was miserable doing it.
