Like vegan. But with muscles.

Lean Protein, Plant Powered.

Half the plate or more is plants. Lean protein and fish go on top — enough to keep the muscle you have, without the saturated fat that usually comes with it. Written by a physician, with every claim cited.

Why it is built this way

You should not have to choose between your heart and your strength.

Two ways of eating well are familiar to most people, and so is the third thing, which is to skip both and trust the training. Each one asks you to give something up.

  1. 1

    Eating mostly plants

    Cholesterol and blood pressure usually improve, and the evidence for that is good. But protein tends to fall short, and over the years muscle goes with it — quietly, until something heavy needs carrying up two flights of stairs.

  2. 2

    Eating mostly protein

    The muscle stays and the training shows. But the plate fills up with red meat, eggs and cheese, fiber becomes an afterthought, and the saturated fat adds up over a long time.

  3. 3

    Relying on exercise to cover the rest

    Training keeps the muscle and does a great deal else, and a lean marathoner can carry a blocked artery for years without feeling a thing. Being fit is not the same as being protected from heart disease.

LP3 takes the useful part of each: the plant base, and lean protein sized to your training rather than your appetite. The food list is short and specific for one reason — leaving out red meat, egg yolks and most dairy is how you fit enough protein in without much saturated fat.

Plants first.
Everything else supports them.

Most plans decide the protein and arrange the vegetables around it. LP3 sets the proportions the other way round.

Plants are the base

Leafy greens, cruciferous vegetables, legumes, berries, whole fruit, nuts and seeds. They are the bulk of every plate, not a side dish: fiber, minerals, and the volume that lets you eat until you are full.

Then supplemented, in the amounts your training actually needs

Lean animal protein

A category, not a single food: chicken and turkey breast, egg whites, and fat-free plain Greek yogurt. Enough at each meal to build and recover, never so much that it crowds the vegetables off the plate. The list is short on purpose. These are the foods that carry a lot of protein and very little saturated fat.

Seafood

Salmon, sardines, cod, shellfish. EPA and DHA, which nothing else on the plate supplies. They are here for your heart rather than your training; the protein is a bonus.

The fats stay in

Not a low-fat diet

Fat comes from whole plant foods and from fish, and it earns its place — in a randomized trial of 7,447 adults at high cardiovascular risk, the arm told to cut fat was the one that did worse.

Where the fat comes from

  • Extra virgin olive oil
  • Avocado
  • Walnuts, almonds, pistachios, pecans
  • Chia, flax, hemp and pumpkin seeds
  • Olives
  • Tahini and nut butters with nothing added
  • Salmon, sardines, mackerel

What is out is the refined and heated version: oils used for deep frying, and the fried food itself. Whole nuts and seeds stay in.

What is on the plate

No weighing, no app, no banned-food anxiety. Your hand is the measuring device and it is always with you.

The LP3 plate: vegetables and legumes fill half or more, a palm of lean protein and a cupped hand of intact starch take the rest
The plate, as the book draws it. Fat is a thumb rather than a share of the surface, and two or three times a week the protein is seafood.

Every plate, in four portions

  • Vegetables and legumeshalf the plate, or more
  • Lean proteina palm
  • Intact starcha cupped hand
  • Fat, with intenta thumb, not a pour

And the three lines it draws

  • Red meat is out.
  • Whole eggs are out and the whites are in.
  • Dairy is out, apart from fat-free plain Greek yogurt.

These are stricter rules than most books draw, and they are not moralism. They are the mechanism: they are what lets you eat enough protein to hold your muscle without importing the saturated fat that usually comes with it.

The complete list — twenty-one foods to build from, ten to leave at the store — is a single page of the book.

Why this book exists

I ran marathons. My main heart artery was 98 percent blocked.

I practiced medical oncology in central Iowa for forty years. I ran marathons, raced triathlons, was lean my whole adult life and never smoked. In the 1990s a heart scan put me at the ninety-first percentile for my age; the statin I was prescribed caused muscle pain, so I stopped taking it and did not take another for twenty-five years.

In 2019 I had five bypasses.

Being fit is worth a great deal. It is not the same as being protected from heart disease, and I had the file to prove it long before I read it properly. Read the full story

He is not a cardiologist and not a registered dietitian, and he says so in chapter one. He ran no trial on this diet, which is why he cites everyone else's.

Why you can check this one

Every claim is cited — including the studies that argue against it.

No trial has tested LP3 itself. The closest anyone has come is the pescatarian group in the Adventist Health Study — plants plus fish — which had the lowest mortality of any diet group among 73,308 adults — narrowly, with the vegans close enough behind that the study cannot separate them.

Fourteen chapters, forty recipes

Five parts and the reference pages. The full contents, chapter by chapter, are on the book page.

  • Part TwoThe methodThe plate, your protein number, fat loss without the math, and the least training that earns the food.
  • Part ThreeThe kitchenThe standing list, the Sunday hour, and the four-week plan.
  • Part FourThe recipesForty of them, every one leading with plants.
  • Part FiveThe real worldEating out, travel, holidays, plateaus, and year two.
  • ReferenceThe pages you photographThe food list, a blank week, the recipes by ingredient, and the Notes.
