“flexible dieting has always been easy
DosageHit daily protein, carb, fat, and fiber targets; fill remainder with foods of choiceCaveatsDoesn't suit those who turn flexibility into excessive junk food intake; requires self-monitoringCertaintyexplicitstrong endorsement -

“the best damn macro tracking and nutrition coaching app on the market
DosageTrack macros, weigh in regularly, weekly check-ins for algorithm-driven adjustmentsCertaintyexplicitstrong endorsement -
Plant-forward diet emphasizing fruits, vegetables, whole grains, legumes, nuts, fish, lean meats, olive oil; strongly reduces CVD risk.
“Mediterranean diet pretty consistently is equal to or outperforms almost all other diets
DosageEmphasize fruits, vegetables, whole grains, legumes, nuts, fish, poultry, eggs, low-fat dairy, olive oil; limit red meatCaveatsHigher food cost; not suitable for vegans; hard if averse to fish/legumesCertaintyexplicitstrong endorsement -
Alternative
Dietary Approach to Stop Hypertension; effective for cardiovascular disease, though adherence tends to be lower than Mediterranean.
“DASH diet is also an effective treatment for cardiovascular disease if you can stick to it
DosageLow sodium, plant-based, lower meat intakeCaveatsAdherence tends to be lower than Mediterranean dietCertaintyexplicitrecommendation -
Healthy plant-based eating reduces cardiovascular disease and cancer risk; must be whole-food based, not processed vegan products.
“top performers when it comes to reducing cardiovascular disease risk
DosageFocus on whole foods; supplement B12 and watch ironCaveatsRisk of B12 and iron deficiency; lower-quality protein; ultra-processed vegan products may increase disease riskCertaintyexplicitrecommendation -
Supplement B12 if following a plant-based diet to avoid deficiency.
“being deficient in vitamin B12. These are easy fixes. You can take supplements
Certaintyexplicitrecommendation -
Aim for ~1.6 g/kg body weight protein; at this level protein quality matters less.
“if you're eating upwards of 1.6 grams per kilogram of body weight, you probably don't need to worry too much about protein quality
Dosage~1.6 g per kg body weight per dayCertaintyexplicitrecommendation -
Use isolated plant protein powders (soy, potato, or corn+wheat blends) to hit protein goals on a plant-based diet.
“get a plant-based protein powder that's isolated. It makes it easier. Soy is fine
Certaintyexplicitrecommendation -
Alternative
Acceptable isolated plant protein for vegans/vegetarians.
“Potato protein isolate is fine
Certaintyexplicitrecommendation -
Less than 40% calories from carbs; effective for short-term weight loss and improves some biomarkers but may raise LDL/ApoB.
Dosage<40% of calories from carbsCaveatsMay raise LDL/ApoB; limit saturated fatCertaintyhedgedrecommendation -
Very high fat, very low carb (<10%) diet that produces ketosis; legitimate therapeutic use for epilepsy.
“a therapeutic ketogenic diet, which is a reasonable treatment for things like epilepsy
Dosage>70% fat, 10-20% protein, <10% carbsCaveatsMay raise LDL; not superior when calories equatedCertaintyexplicitrecommendation -
Limit saturated fat intake, especially on low-carb diets, due to LDL/ApoB elevation and CVD risk.
“I just recommend limiting saturated fat intake
DosageReplace with monounsaturated or polyunsaturated fatsCertaintyexplicitmild caution -

Meat-only diet; Norton is critical due to zero fiber and increased CVD/cancer/mortality risk.
“utterly devoid of fiber and this will increase the risk of cardiovascular disease, cancer, and mortality
CaveatsMay help individuals who lose significant weight when no other diet works for themCertaintyexplicitstrong warning -
Use elimination diets short-term to identify GI triggers, then reintroduce foods one by one — don't stay on indefinitely.
“The point of an elimination diet is to cut back to get your symptoms under control and then one by one, add foods back
DosageEliminate, stabilize, then reintroduce foods one at a timeCertaintyexplicitrecommendation -
Consume fiber consistently — it lowers CVD, cancer, and all-cause mortality risk in a dose-dependent manner.
“Fiber is the longevity hack
DosageHigher intake yields greater benefit; dose-response effectCaveatsReduce during IBD flare-ups; some FODMAP sensitivities require gradual reintroductionCertaintyexplicitstrong endorsement -
Time-restricted eating can be useful for adherence and short-term metabolic improvements but isn't magical; no human longevity evidence.
“intermittent fasting is a reasonable way to improve blood lipids and insulin sensitivity
DosageTypical 16:8, 18:6, 20:4, OMAD, alternate day, or 5:2CaveatsMay reduce lean mass; associated with disordered eating; no proven longevity benefit in humansCertaintyhedgedrecommendation
