His Personal Journey

PD wasn’t always an example of good health.

13 years ago, in 2009, PD was a long time vegan battling with chronic fatigue9Twitter thread on Chronic Fatigue Recovery | September 2019.

He was 5’10” 130lbs, and his main form of exercise was long distance running.

The advice he was getting from conventional medicine wasn’t working, and he realized he had to find a solution for himself.

He decided to switch to a primal diet, eating whole foods with plenty of meat, eggs, fish, and dairy.

Gradually his energy started coming back.

At that point he added in weight training, packed on 25lbs of muscle and never looked back.

Some time after recovery he wrote his first book Smash Chronic Fatigue.

He’s since gone on to write 9 further books, but his main, ongoing, content outlet is Twitter.

Examples of What He Eats

In this section we’ll go through some examples of meals that PD has shared.

With the idea that this provides inspiration for others who want to emulate aspects of what he does.


Below are images PD has shared of his breakfasts:

^ Eggs and Chorizo with pear – source

^ Quick breakfast, boiled eggs, corn tortillas, olive oil and salt. 14g of carbs per tortilla – source

^ Steak “the original protein shake” – source


PD’s food pics appear to be largely breakfast or dinners.

Perhaps partly because his lunches are lighter, and closer to snacks:

A few examples include:

^ Boiled eggs, olive oil, salt and corn tortilla

What He Avoids

PD is a big proponent of avoiding refined grains, sugar and seed oils.

Remarkably, just doing that could help us all live healthier lives.

Sugar & Sweeteners

PD avoids sugar and sweeteners.

He sees sweeteners as a stepping stone for quitting a sugar addiction, but not something one should be consuming otherwise.

Suggesting stevia may be healthier than synthetic sweeteners such as sucralose, aspartame, acesulfame etc.

^ Tweet source

Interestingly, he points out that most people aren’t solely addicted to sugar.

As he says, they will rarely take a spoon of pure sugar and eat it.

Instead it’s the combination of sugar + carbohydrates/fats/flavorings that does it.

^ Tweet source

I think that’s fair to say – certainly I’ve never thought about eating spoonfuls of sugar. However, finishing the last chocolate cookie in the cupboard? Now that’s a temptation.

He also makes an interesting point about steak; it’s not attractive in the way cookies and candies are. You’ll eat it if you’re actually hungry though:

I think it’s fair to say that most of us would be very pleased to look lean and healthy like PD late into our 60s.

Hopefully the above content gives a window into the type of diet he uses to achieve this.

Of course, it’s not the only way, but it’s certainly an example that’s clearly working.

Lastly I’d be remissed if I didn’t mention that PD runs a coaching program to help overweight people lose weight and get back on track.
