Diet

Build most meals from whole or minimally processed foods—vegetables, fruit, eggs, meat, fish, beans, oats, rice, and other single-ingredient staples—while keeping ultra-processed foods to a small minority of intake. A common target across the recommendations is roughly 75–90% of calories from these foods, with only limited room for packaged snacks, refined sweets, and engineered convenience foods. This pattern is favored because it tends to improve satiety, reduce overeating, and support better metabolic, gut, and overall health than a heavily processed diet.

Aim for roughly 25–35 grams of fiber per day, mainly from fruits, vegetables, legumes, whole grains, and other whole plant foods. The common rationale is that fiber feeds the gut microbiome, supports regularity and satiety, and can blunt glucose spikes while also lowering inflammation and improving overall metabolic health.

Add 1 to 4 servings per day of refrigerated, live-culture fermented foods such as kimchi, sauerkraut, kefir, natto, or plain yogurt, and increase intake gradually if you are not used to them. The emphasis is on low-sugar, minimally processed versions rather than shelf-stable or heat-killed products. This pattern is used to boost gut microbiome diversity and support lower inflammation, with possible downstream benefits for gut barrier function and serotonin production.

Aim for a consistently high daily protein intake, commonly around 1 gram per pound of body weight per day, with enough protein at each meal to reach roughly 30–50 grams per serving. Many recommendations also emphasize spreading protein across breakfast, lunch, and dinner rather than saving it for one meal. The main goals are to maximize muscle protein synthesis and preserve lean mass while also improving satiety, reducing overeating, and supporting body composition during dieting or recovery.

Use caffeine early in the day, typically as coffee, to boost alertness and support focused work or a morning wake-up routine. Front-load the dose and avoid it later in the afternoon or evening—often at least 8 to 12 hours before bed, and earlier if you’re sensitive—to reduce sleep disruption and preserve REM sleep.

Use non-smoked yerba mate as an early-day caffeine source, often in place of coffee or other caffeinated drinks. The idea is to get a focused stimulant effect while avoiding late caffeine that can disrupt sleep, and to favor non-smoked varieties because smoked yerba mate may carry carcinogenic risk.

Prioritize whole-food sources of omega-3s, especially fatty fish and seafood such as salmon, sardines, anchovies, mackerel, herring, and caviar; algae can be a vegan EPA source, and plant options like flax, chia, walnuts, and soybeans can help round things out. The main rationale is to raise EPA/DHA intake through food rather than supplements when possible, supporting brain function and potentially helping with sugar cravings, skin health, headaches, and overall nutrient balance.

This recommendation is to minimize added sugar in everyday eating, with a practical label-reading rule of keeping it to about 4 grams per serving or less and avoiding hidden sugars in processed foods. The main idea is that cutting back on refined and added sugars helps reduce cravings, supports steadier energy and metabolism, and lowers the glucose/insulin spikes that make sugary foods so reinforcing.

This recommendation is to keep alcohol intake very low, with zero being ideal and roughly 0–2 standard drinks per week the commonly cited upper range for generally healthy non-alcoholic adults. The rationale is that health risks rise with increasing regular consumption, including worse brain health and greater overall disease burden, so staying near abstinence appears safest.

A carbohydrate-restricted diet used specifically to push the body into ketosis, often with blood ketones monitored to confirm the effect. In the mental-health use case, the protocol aims for measurable ketone levels rather than just “eating low carb,” because ketosis is thought to provide a stronger therapeutic metabolic shift for mood and related symptoms.

Eat a more carbohydrate- and starch-heavy dinner or late-evening meal, often using foods like rice, pasta, oats, or potatoes, rather than keeping dinner very low carb. The idea is that evening carbs can help blunt cortisol, increase serotonin/tryptophan availability, and make it easier to feel calm, fall asleep, and stay asleep.

Prioritize fats from whole-food sources, especially plant-based options like avocados, nuts, seeds, and olive oil, with some omega-3-rich fish and other minimally processed fats. The common theme is to replace saturated and industrial fats with monounsaturated and polyunsaturated fats, which may better support metabolic and cardiovascular health while also providing the cholesterol needed for hormone production.

Keep carbohydrate intake low or absent during the day, especially at breakfast and lunch, and favor meals built around protein, moderate fat, and non-starchy foods. The idea is to reduce post-meal sluggishness and support sustained wakefulness, focus, and attention by biasing the body toward a more alert, catecholamine-friendly state.

Prioritize protein from high-quality animal foods such as meat, fish, eggs, poultry, and whey, with an emphasis on sourcing that is pasture-raised, organic, or otherwise minimally treated. The idea is that these foods provide a dense, complete amino acid profile that is efficiently used to support muscle and overall nutrition.

Use water plus electrolytes—especially sodium, with potassium and magnesium when available—when rehydrating after waking, after caffeine, or around exercise and heavy sweating. A small pinch of salt in water or an electrolyte-containing drink can help replace losses, support hydration, and improve nerve-to-muscle function and physical performance.

Use carbohydrates strategically around intense or repeated training sessions rather than eating them broadly all day. The common protocol is to take in carbs before, during, or especially after hard work—often with starches or high-glycemic foods plus protein—to restore glycogen and support recovery when energy demands are high or sessions are close together. This helps maintain performance in high-intensity efforts and speeds replenishment when recovery time is short.

Use iodized table salt as a routine dietary source of iodine, and include iodine-rich foods like seaweed or kelp when needed. The goal is to keep iodine intake sufficient without overdoing it, since iodine is required for normal thyroid hormone production and helps prevent deficiency-related problems like goiter.

Drink water with a small pinch to about half a teaspoon of salt, often first thing in the morning and sometimes during fasting or before a workout. The idea is to improve hydration and sodium balance, which may help with lightheadedness, shakiness, low blood pressure, or reduced alertness when sodium intake is low.

An eating pattern built around mostly whole, minimally processed foods while limiting fried, ultra-processed, and other inflammatory foods. It is commonly framed as Mediterranean- or Ayurvedic-style and emphasizes anti-inflammatory choices over packaged foods. The goal is to lower systemic inflammation and support better symptom control, including skin, fertility, and perimenopause-related concerns.

Use starchy carbohydrates as a deliberate fuel source rather than avoiding them entirely, especially around hard resistance training. Common choices include oatmeal, rice, potatoes, pasta, and similar “clean” starches, with portions kept controlled and the plate method used to keep them in the smallest section. The goal is to support training performance, replenish glycogen, and improve long-term adherence without overdoing calories.

Keep non-caloric sweeteners to a minimum rather than using them as a default substitute for sugar. The common rationale is that they can still promote insulin release, cravings, and hunger, and in larger amounts may also disrupt the gut microbiome. Water or other unsweetened drinks are preferred when the goal is better appetite control and metabolic health.

Increase intake of dark leafy greens such as spinach, kale, Swiss chard, and romaine as a regular part of the diet. These foods are emphasized as nutrient-dense sources of magnesium and as a core feature of heart-healthy eating patterns like DASH, with the main benefit being support for preserved cognitive performance and overall brain health.

Avoid drinking alcohol in the evening or near bedtime if you want better sleep. Alcohol can make you feel sleepy at first, but it fragments sleep later in the night and suppresses REM and other restorative sleep stages, leaving sleep less refreshing overall.

During fasting, plain water is the baseline drink, and unsweetened tea or black coffee are commonly treated as compatible additions. The idea is to stay hydrated and, if desired, use caffeine for alertness without adding calories that would meaningfully interrupt the fast.

Increase intake of tyrosine-rich foods such as red meat, nuts, Parmesan, and other protein-containing foods to support dopamine and catecholamine production. The idea is that providing more dietary tyrosine can help maintain baseline dopamine levels and promote alertness and wakefulness, especially when mental energy is low.

Build each meal around a meaningful protein source and spread protein intake across breakfast, lunch, and dinner rather than saving most of it for later in the day. A practical target is roughly 30–50 g of high-quality protein per meal, using lean options like chicken, fish, or beef. This supports satiety and helps maintain or build lean muscle by keeping daily protein intake consistently high.

Eat foods high in tryptophan, often paired with carbohydrates, such as turkey, tuna, milk, oats, and cheese. The idea is to support serotonin production and availability, which may help with sleep, mood, and other serotonin-related benefits.

After a hard workout, especially if you trained fasted or early in the day, eat a meal with starchy carbohydrates such as rice, oatmeal, pasta, bread, or fruit. The idea is to replenish energy and support recovery, with one cited benefit being a reduction in exercise-induced inflammation.

Use Brazil nuts as a concentrated food source of selenium, typically just 1–3 nuts per day rather than large handfuls. This helps support thyroid hormone production and overall thyroid function because selenium is a key nutrient for thyroid metabolism, but too much can push intake into excess.

A simple supportive practice is to use garlic during cold and flu season, often by chewing one raw clove daily through the winter. Some versions also use fermented garlic. The idea is that garlic may help support the body’s response to respiratory infections and provide a low-cost, food-based immune boost.
