In 40 days, Abel James lost 20 pounds— and he wasn’t starving himself. Instead, he enjoyed foods like chicken Parmesan, pulled pork sliders and bacon burgers. James shares his unusual weight loss strategy in his new book, “The Wild Diet.”

Traditionally, diets are synonymous with deprivation.

“When you’re constantly starving yourself, you kind of enter this starvation mode and we’ve become afraid of our food,” James told FoxNews.com.

With “The Wild Diet,” James presents nutritional and fitness strategies to engage the body to burning fat. Eating “wild” foods, especially vegetables, meats, and fruits, keep you feeling full and satisfied, unlike fatty foods and quick-burning carbohydrates, such as pasta and sugar.

The diet follows this principle: “Eat plenty of whole and naturally edible foods; and be skeptical of manipulated, processed, and invented food products. This way your body will burn fat as its main fuel source, returning you to the lean human body that’s already part of your genetic code.”

Getting rid of processed foods that are filled with sugars and starches, and putting the pleasure back into food by eating whole foods is important, James said. Avoiding foods that are freeze-dried and otherwise packaged for convenience is key, as is knowing where your fresh produce, vegetables and nuts come from.

“Whole foods are foods that are as close to the source as possible,” explained James.

Finding these foods is not as difficult as you’d believe – farmers’ markets are becoming more and more popular and they are a great resource. James does warn that a lot of so-called “health foods” are actually junk food in disguise and you should know the common tricks used to trick consumers. The term “fat-free” for example sounds like a great option but James’ book points out that these foods are usually packed with sugars and chemicals to add flavor.

In addition to a “wild diet,” James’ book offers even more surprises with his exercise routine- a seven-minute workout. Formerly a marathon runner who ran than 50 miles a week, James discovered that he lost more weight and gained more muscle by doing high-intensity exercises. In his book, James explains that your body responds better to quality over quantity, that “overtraining” wastes away your muscles and restores fat.

Getting into shape doesn’t have to be a struggle, James said. You can eat what you crave and don’t have to be “chained to a treadmill” for exercise.
