For Vince Wilfork,
he found something this offseason that has him feeling better than he's felt in his 11 seasons in the NFL.
After years of dieting on his own and eating foods that books or websites suggested, Wilfork took a blood test that told him -- with Harper's help -- what he really needed.
Harper's goal is to get an individualized plan that works for each of his players, and Wilfork said this test helped them determine his.
"You hear a lot of people talk about eating healthy stuff like nuts and almonds," Wilfork said. "Well, I'm actually high on that end. I'm actually a little allergic to nuts and almonds and avocados and stuff. It really broke it down to your body. That test was mainly for your body, what your body can accept. A lot of people go out with a generic diet method of, 'You gotta eat this.' Well, if you're body don't accept it, you can't eat it."
In addition to steering clear of foods like nuts and avocados, Wilfork said that this season he's stayed away from eating as many carbs as he has in the past. It's been tough for him, a rice and pasta lover, but the results have been staggering.
"Nothing really made me feel like how I feel now," Wilfork said. "This is the best I ever felt. My body, my body don't feel like it's been through a 20, 21 game season already. I'm still fresh. My body, I don't have no aches and bruises. I think a lot of that have to do with my nutrition, understanding what you're putting into your body.
"I still feel the difference. Going this whole season, feeling the way I feel, I never felt that. And I'm 33. I never felt like this in a season ever. It's crazy . . . It took me 11 years, but I got there. Better late than never."
...
But it wasn't until this season that Wilfork has felt the effects of a dietary plan made to his specifications. What's helped the Patriots is that he's feeling better without having lost any of the weight or the strength that has made him one of the centerpieces of the team's defense for over a decade.
Pressed on the issue of his weight, Wilfork insisted he is playing at his listed 325 pounds.
"Everybody always questions me because I got a big belly," Wilfork said with a smile. "I tell them all the time that I'm always gonna have a belly. I'm always gonna have a belly. That's my trademark. I'm gonna have a belly. But when you do body-fat tests and all that stuff, all my fat is in my stomach. Everywhere else, I mean, you cut my belly out you'd think I'm a linebacker or something. You know what I mean? Everyone always questions me about that, but there's no question. That's what it is. Just because I got a big belly, I'm proportioned a little bit differently than everybody else."
