William Li & Eat to Beat: The Complete Guide

William W. Li, MD, is a physician, researcher, and president of the Angiogenesis Foundation. He trained in the lineage of Judah Folkman's work on blood-vessel growth as a disease lever — too much angiogenesis can feed tumors and retinopathy; too little impairs wound healing and heart repair.

His 2010 TED talk, Can We Eat to Starve Cancer?, argued that diet can tilt angiogenesis the way some drugs do. Eat to Beat Disease (2019) expanded that into five defense systems and 200+ foods. Eat to Beat Your Diet (2023) applied the same lens to metabolism, body fat, and a four-week meal plan. He is not a supplement influencer first — the books are grocery-first.

Angiogenesis: the body constantly builds and prunes capillaries. Li's signature claim is that some foods (lycopene-rich tomatoes, green tea catechins, soy isoflavones) help keep vessel growth in a healthy range — supporting heart tissue where vessels are needed and being less hospitable where tumors try to recruit a blood supply.

Regeneration: circulating stem and progenitor cells help repair tissue. Li highlights omega-3-rich fish, coffee polyphenols, and other foods studied for stem-cell mobilization — interesting, still early as a 'eat this to regenerate' slogan.

Microbiome: fermented foods, fiber, and plant diversity feed gut ecology that talks to immunity and metabolism. This is the least controversial chapter if you already read our gut-microbiome guide.

DNA protection: antioxidants, folate-rich plants, and lower oxidative load support repair and telomere-adjacent health. Epidemiology is stronger than any single 'DNA food.'

Immunity: mushrooms, garlic, crucifers, and adequate protein and sleep keep innate and adaptive immunity useful — not 'boosted' into chaos.

Li's own summary: support the five defense systems by eating up to five times a day and folding in at least five health-supporting foods you already enjoy. Cover all five systems across the day — not five new foods at every single sitting.

Grand slammers in his language are foods that hit more than one system (extra virgin olive oil, green tea, berries, tomatoes, mushrooms). Start there if the list feels long.

What it is not: a cleanse, a lectin ban, or a fasting religion. You can run 5×5×5 next to time-restricted eating or a CGM. You should not use it to delay indicated medical care.

The sequel treats body fat as a living, vascular organ. Li discusses brown and beige fat, why some fat is metabolically noisier, and foods and patterns that support a healthier metabolic set point — still in the add-foods voice.

The four-week plan, swaps, and recipes are the practical reason to buy the second book. Effect sizes will not match semaglutide trials. If you are losing weight, keep protein and lifting in the week (see protein-longevity and strength-training-longevity).

Original Longevindex recipes aligned with Li's food lists — not copied from his books. For his tested recipes and the four-week diet plan, buy the Amazon editions below.

San Marzano tomato and basil skillet: Warm extra virgin olive oil, garlic, and canned San Marzano tomatoes 15 minutes. Finish with basil. Lycopene is more available from cooked tomatoes with fat — a Li staple, not a raw-only salad.

Green tea and blueberry morning: Brew jasmine or green tea. Bowl of blueberries, walnuts, and plain yogurt or coconut yogurt. Hits angiogenesis, DNA-protection, and microbiome columns before 10am.

Mushroom and garlic sauté: Brown mixed mushrooms (shiitake, oyster, cremini) in olive oil with garlic and thyme. Serve on sourdough or next to salmon. Mushrooms and alliums are immunity-chapter regulars.

Sheet-pan salmon and broccoli: Wild salmon, broccoli florets, olive oil, lemon. 400°F (205°C) for 14–18 minutes. Omega-3 plus crucifers — regeneration and DNA-protection adjacent without a supplement drawer.

Dark chocolate square and kiwi: After dinner, 1 oz high-cacao chocolate and a sliced kiwi. Li's lists include both; keep chocolate as a dose, not a bag.

Gundry: subtracts lectins and runs elimination phases. Li: adds defense-system foods and keeps bread, beans, and soy on the table when you tolerate them. If restriction burns you out, Li is the gentler grocery protocol.

Sinclair: fasting windows, NAD+ precursors, and aging-as-disease rhetoric. Li barely needs a capsule. You can time-restrict and still run 5×5×5 inside the eating window.

Attia / protein-first: Li will not hit 1.6–2.2 g/kg protein by accident. Steal his plants and oil; keep the protein math from our protein guide.

Eat to Beat Disease (hardcover) — ASIN 1538714620. Start here for the five systems and the 5×5×5 plan. Best gift edition.

Eat to Beat Disease (paperback) — ASIN 1538714612. Same framework, cheaper to highlight in the kitchen. Later printings advertise extra immunity recipes.

Eat to Beat Your Diet (2023) — ASIN 1538753901. Metabolism, body fat, and a four-week meal plan. Buy second unless weight is the only reason you showed up.

Cancer and chronic disease: food patterns change risk. They do not replace screening, biopsy, or treatment. Li is a researcher-communicator, not your oncologist.

Allergies and interactions: soy, fish, tea, and high-polyphenol intakes are not universal. Warfarin and some chemo regimens need a clinician before you 'eat to starve' anything.

Over-promising: angiogenesis is real biology. Turning every berry into a targeted therapy is marketing. Use the lists as a Mediterranean-plus shopping guide.

r/nutrition is kinder to Li than to Gundry: less food fear, more overlap with existing guidelines. r/longevity treats him as the food-as-medicine communicator, not the mTOR or NAD+ guy.

Pair this guide with gut-microbiome, omega-3, intermittent-fasting, glucose-spike-control, and gundry-microbiome if you want the contrast set.
