With thanksgiving just two days away, dieting is probably the last thing on your mind.

But, if you want to get a jump on fitness for the New Year, you may want to try “the Whole30” diet.

FYI.... It consists of a lot of Greens.

Getting outside for some good exercise is also key in this very popular diet that is giving people incredible results.

Kristopher Ryan is a CrossFit trainer and says the Whole30 diet has impacted not just his food choices but the choices of others.

"The Whole30 is something you should try just if you’re looking to want to feel better as a person," Ryan said.

Melissa Hartwig is the co-creator of the Whole30 diet.

"I'm a recovering drug addict. I've been clean for 17 years. Food and drugs are not that different," said Hartwig in an interview with KHOU, out sister station in Houston.

Hartwig said the Whole30 diet is intended to pull you away from foods that your body doesn't need. That's why for 30 days you can't have alcohol, carbs, grains, dairy, or foods with added sugars. That means no to most desserts.

"It's remarkable. The body has a remarkable capability of healing. Cravings are diminished, skin gets better, you sleep better," Hartwig said.

Ryan can vouch for that.

"As you start eliminating different foods. I learned that a lot of dairy product impacted my body," Ryan said. "It was making me feel heavier maybe bloated at some times."

University Hospital Dietitian Dahlia Gomez agrees dairy can be problematic.

"It is a cow’s milk specifically geared for baby cows. We're the only beings that drink another organism’s milk."

"I felt a lot more energized and I also didn't feel as sluggish. I was able to perform better as an athlete," Ryan said.

The Whole30 is also a good option for those trying to lose weight and cleanse their body.

"You can definitely lose weight because you get rid of the junk foods," Gomez said.

Here's what you can eat:

Lean meats like chicken, fish and pork.

Foods with good fats like nuts and avocados. And fruits and vegetables.

Don’t forget to get outside for some good ol' fashion sunshine.

Gomez said, "Research suggests that you need 5-30 minutes of vitamin D or direct sun exposure without sunscreen."

For Ryan, it was a personal choice he says he doesn't regret.
