LAS VEGAS — With Israel behind him, Amar’e Stoudemire is raring to get back in the NBA and feels his diet has given him a shot at age 36.

Stoudemire worked out for 15 teams here in hopes of getting a training camp invite and be an influence on a team’s younger players. The Knicks, whose owner James Dolan adores Stoudemire, were at the workout.

Appearing on MSG Network’s “MSG 150’’ show Tuesday night, Stoudemire, in excerpts obtained by The Post, said, “For me I got down to 235 [pounds], which is my lowest weight I’ve ever played at. I got as strong as I could possibly be.

“I worked on physical therapy and my physical training to the point where I took every exercise very seriously and critiqued every single workout and exercise, so my body as a result has been feeling great.”

The former All-Star signed a five-year, $100 million contract with the Knicks nine years ago, but his knees didn’t hold up. The Knicks bought him out in his final year.

Stoudemire, a converted Jew, last played in the NBA with the Heat in 2015-16 after which he embarked on a short career in Jerusalem. He said he never really retired in his mind despite signing a one-day contract to retire as a Knick in 2016.

“I was never really done,’’ Stoudemire said. “I took kind of a sabbatical leave and I went to go learn over in Israel for two and a half years or so. So I went there and when I was still learning, I was able to also play basketball and keep myself in shape. I always stayed in top shape. I didn’t really remove myself too far from being in basketball shape.”

Stoudemire feels his “leadership quality’’ will be key to joining an NBA squad. The Knicks may not have an open roster spot if they sign both Reggie Bullock, whose physical raised a red flag, and Marcus Morris.

“My body feels amazing, so we’ll see if the opportunity becomes a reality,” Stoudemire said on the show. “A lot of the teams have a lot of young players and a lot of players that can learn how to train, how to become professionals and how to become great basketball players. And leadership goes a long way with teams in order to get from a playoff team to a contending championship team.

“From that standpoint, I have a lot to offer. And also as a basketball player, I still have a lot of game left. I can help a team in any way they need.”
