No. 62DASH Diet
DASH stands for Dietary Approaches to Stop Hypertension. It was tested in feeding trials funded by the US National Institutes of Health in the 1990s. The plan is rich in vegetables, fruit, whole grains, beans, nuts, fish, poultry and low-fat dairy, and low in red meat, sweets, sugary drinks and salt. A follow-up trial, DASH-Sodium, tested the same diet at different levels of salt.
Strengths
- Strong evidence, a rarity in the diet world. In the original DASH trial, blood pressure fell within a few weeks, and in DASH-Sodium it fell further when salt was also cut.
- Rich in potassium, magnesium, calcium and fiber from whole foods, not a pill bottle.
- A balanced, flexible pattern the whole family can eat, recommended by many heart and health organizations.
Watch out for
- Many people fixate on salt alone, but the whole pattern is what made the trials work.
- Most salt comes from packaged and restaurant food, not the salt shaker. The shaker takes the blame; the frozen dinner gets away with it.
- The original plan used low-fat dairy, the advice of its time. A small later study suggested full-fat dairy worked about as well.
- It is not a weight-loss diet; you lose weight only if you also eat less, a rule no diet has yet managed to repeal.
Eating well within it
- Fill half your plate with vegetables and fruit, and add beans or lentils several times a week.
- Cook from scratch and season with herbs, garlic, lemon and spices instead of salt.
- Choose plain yogurt, milk and cheese over the sweetened versions, which are dessert in disguise.
- Swap chips and crackers for unsalted nuts. Same crunch, none of the salt.
Possible supplement needs
Usually none, since the diet is nutrient-rich. Vitamin D if sun exposure is low.
Who should be careful
People with kidney disease, and people taking medicines that raise potassium (including some blood pressure drugs and diuretics), should watch potassium, since DASH is high in it.
No. 63MIND Diet
MIND stands for Mediterranean-DASH Intervention for Neurodegenerative Delay. It was created by nutrition researcher Martha Clare Morris and colleagues at Rush University in Chicago and published in 2015. It blends the Mediterranean and DASH diets around 10 brain-healthy food groups: leafy greens, other vegetables, nuts, berries, beans, whole grains, fish, poultry, olive oil and (for some) wine. It limits five groups: red meat, butter and stick margarine, cheese, pastries and sweets, and fried or fast food. In other words, the drive-through is not brain food.
Strengths
- In observational studies of older adults in Chicago, people whose eating most closely matched MIND had slower mental decline and a lower rate of Alzheimer's disease.
- Simple, positive targets, such as leafy greens most days and berries a few times a week.
- Built on whole foods that also support heart health, so your heart gets a free ride.
Watch out for
- Observational studies show links, not proof. In a three-year trial published in the New England Journal of Medicine in 2023, older adults on MIND did not score significantly better on thinking and memory tests than a control group; both groups cut calories slightly and both improved a little.
- Wine is optional; people who don't drink should not start. Nobody needs a corkscrew to look after their brain.
- Its limits on butter and cheese are stricter than many traditional diets, and the evidence on these foods is mixed.
Eating well within it
- Add a big handful of leafy greens to eggs, soups or stews.
- Keep frozen berries on hand for breakfast and snacks. They never go soft in the back of the fridge.
- Snack on nuts instead of pastries, and cook with extra-virgin olive oil.
Possible supplement needs
Usually few. Vitamin D if sun exposure is low, omega-3 if fish rarely makes it to the plate, and vitamin B12 is worth checking in older adults.
Who should be careful
People on blood thinners who suddenly change how many leafy greens (vitamin K) they eat. Memory loss has many causes, some easily fixed, such as low B12 or an underactive thyroid, so find the cause.
No. 64Anti-Inflammatory Diet
An eating style meant to calm long-lasting, low-grade inflammation, the slow simmer that researchers link to heart disease, diabetes and other chronic illness. Integrative-medicine physician Dr. Andrew Weil, creator of an anti-inflammatory food pyramid, is one of its best-known teachers; many others offer their own versions. Most share a core of colorful vegetables and fruit, oily fish, olive oil, beans, nuts, whole grains, tea, and spices such as turmeric and ginger, with little sugar or ultra-processed food.
Strengths
- Closely resembles the Mediterranean diet, which has good evidence for heart health. Good company to keep.
- Studies link diets high in vegetables, fruit, fish and fiber with lower levels of inflammation markers in the blood.
- Flexible enough to fit many cultures and cuisines; no passport required.
Watch out for
- There is no single official definition, so books and websites disagree about which foods are "inflammatory" (for example, nightshades, dairy or grains). Read three blogs and you may have nothing left to eat.
- Claims that it cures arthritis, autoimmune disease or pain go well beyond the evidence.
- Turmeric in food is safe for most people, but concentrated curcumin supplements can interact with blood thinners and have rarely been linked to liver problems. A sprinkle is not a capsule.
- "Anti-inflammatory" labels on packaged foods are often marketing. If the box has to tell you, be suspicious.
Eating well within it
- Eat oily fish such as salmon, sardines or mackerel twice a week, or add ground flaxseed and walnuts.
- Cook with extra-virgin olive oil, and use turmeric (with black pepper, its trusty sidekick), ginger and garlic generously.
- Aim for several colors of vegetables and fruit every day. Beige doesn't count.
- Swap sweet drinks for water or green tea.
Possible supplement needs
Omega-3 if fish is rarely eaten, and vitamin D if sun exposure is low. Concentrated curcumin and high-dose fish oil both thin the blood.
Who should be careful
People on blood thinners or diabetes medicines who are considering turmeric or fish oil supplements. Anyone with a diagnosed inflammatory condition should use this diet alongside treatment, not instead of it.
No. 65GAPS Diet
GAPS stands for Gut and Psychology Syndrome, a term coined by Dr. Natasha Campbell-McBride in her book of the same name. Building on the Specific Carbohydrate Diet, she teaches that damage to the gut and its bacteria can affect the brain and contribute to autism, ADHD, depression and digestive illness. A six-stage Introduction Diet of homemade meat stock, soups, boiled meats and fermented vegetables leads to the Full GAPS Diet (no grains, sugar, starchy vegetables or processed food), which she recommends for about 1.5 to 2 years. That is a commitment measured in years, not weeks.
Strengths
- Replaces sugar and ultra-processed food with home-cooked meals, broth, vegetables and traditional fermented foods. The snack aisle loses this round.
- Many families report better digestion and behavior, though these are personal accounts rather than measured results.
- Teaches useful kitchen skills, such as making stock and fermenting vegetables, that last well beyond any diet.
Watch out for
- There are no controlled trials of GAPS, and "Gut and Psychology Syndrome" is not a recognized medical diagnosis.
- Very restrictive, especially in the Introduction stages, and hard to keep up for two years.
- Children, especially those with autism who already eat few foods, may fall short on calories, calcium and fiber.
- Any improvement may come from cutting out junk food rather than from the theory behind the diet. Sometimes the quiet hero is simply the missing junk food.
Eating well within it
- Use a wide range of allowed vegetables, and add homemade yogurt or kefir, if tolerated, for calcium.
- Move through the Introduction stages steadily rather than living on broth. Broth is a starting point, not a destination.
- Include eggs, fish, well-cooked squash and (when allowed) nuts for energy.
Possible supplement needs
Dr. Campbell-McBride recommends probiotics, cod liver oil and digestive enzymes. Calcium and vitamin D may need checking if dairy is limited.
Who should be careful
Children (have a pediatrician track growth), pregnant or breastfeeding women, and anyone underweight or with a history of eating disorders. GAPS should never replace medical, psychological or developmental care.
In depth
Dr. Natasha Campbell-McBride: GAPS
Dr. Natasha Campbell-McBride trained in medicine and neurology in Russia and later in nutrition in the U.K. After using diet to help her own son with autism, she wrote Gut and Psychology Syndrome (2004; 2nd edition 2010), and later Gut and Physiology Syndrome (2020). "GAPS" stands for both.
Her theory. An unbalanced gut flora (from antibiotics, processed food and other causes) damages the gut wall. Toxins and partly digested food then pass into the blood and affect the brain and body. She links this to learning and behavior conditions, depression and other mental illness (gut and psychology), and to autoimmune and other physical illness (gut and physiology).
The GAPS Introduction Diet moves through six stages, moving on only when the current foods are tolerated. It can take three weeks to a year.
| Stage | Foods added (summary) |
|---|---|
| 1 | Homemade meat stock and soups made with it; juices from fermented vegetables, introduced a little at a time; ginger, mint or chamomile tea |
| 2 | Raw egg yolks added to soups, then soft-cooked eggs; stews and casseroles; homemade ghee |
| 3 | Ripe avocado; fermented vegetables; GAPS pancakes made from nut butter, eggs and squash; scrambled eggs cooked in animal fat |
| 4 | Roasted and grilled meats; cold-pressed olive oil; fresh vegetable juices; bread made from ground nuts |
| 5 | Cooked apple purée; raw vegetables such as lettuce and peeled cucumber; more fruit juice |
| 6 | Peeled raw apple and more raw fruit; baked goods sweetened with a little dried fruit or honey |
Meat stock and bone broth. In GAPS, meat stock is made by simmering bones with meat, joints and connective tissue for a few hours (about 1.5 to 3.5 hours), until the meat falls off the bone. It is gentler and lower in histamine than bone broth simmered for 24 hours or more. In the video, her one daily habit for everyone is a bowl of soup made with meat stock.
The Full GAPS Diet follows for about a year and a half to two years: meat, fish, eggs, fermented dairy if tolerated, vegetables, some fruit, nuts, animal fats, stock and fermented foods every day; no grains, sugar, starchy vegetables or processed food. Other foods are reintroduced only after about six months of normal digestion.
"Die-off." Campbell-McBride teaches that fermented foods and probiotics are introduced slowly, because a fast start can bring temporary symptoms she attributes to dying microbes (bloating, fatigue, skin flares).
Where others disagree. GAPS has no controlled trials; the evidence is case stories. Campbell-McBride says GAPS can help nearly every chronic disease, including some neurological diseases most doctors consider incurable. Those are her claims. GAPS is also very restrictive, and children with autism often already eat a narrow range of foods, so they can become undernourished. For a child, GAPS means watching growth and weight closely; for anyone with a serious illness, GAPS goes alongside their medical care, ideally with a GAPS-trained practitioner.
No. 66Specific Carbohydrate Diet
Dr. Sidney Haas, a New York pediatrician, developed this diet in the first half of the 1900s for children with celiac disease. Elaine Gottschall brought it to a wide audience after it helped her daughter's ulcerative colitis, and wrote the book Breaking the Vicious Cycle. The idea is that double sugars and starches are poorly digested and end up feeding unfriendly gut bacteria instead of you. So the diet allows honey, most fruit, non-starchy vegetables, meat, fish, eggs, nuts, aged cheeses and 24-hour homemade yogurt, and bans grains, table sugar, potatoes and other starches, most milk, and processed food.
Strengths
- Some small studies, mostly in children with Crohn's disease, found better symptoms and, in some cases, improved lab results.
- Whole-food based, with no ultra-processed food or added sugar beyond honey. The candy aisle simply drops off the map.
- A long history and many tested recipes, so you are not inventing dinner from scratch every night.
Watch out for
- Evidence is limited to small studies and patient reports. A 2021 trial in adults with Crohn's disease found symptoms improved about as much on a Mediterranean diet, which is easier to follow.
- Cutting grains and most beans can lower fiber, B vitamins and calcium.
- Strict and time-consuming: the special yogurt and the label reading both take real work. Food labels were not written with you in mind.
- It does not replace medical treatment, and flares can be serious.
Eating well within it
- Make the 24-hour yogurt, if dairy is tolerated, for calcium and helpful bacteria.
- Use squash, carrots and allowed beans such as lentils (once tolerated) for fiber and energy.
- Bake with almond or other nut flours instead of grain flours.
- Peel and cook vegetables well during flares, when gentler is better.
Possible supplement needs
People with inflammatory bowel disease are often low in iron, vitamin D and B12; these are worth testing. Calcium if dairy is limited.
Who should be careful
People with Crohn's disease or colitis should work with their gastroenterologist and, ideally, a dietitian. Children and anyone underweight need their weight and growth monitored.
No. 67Autoimmune Protocol (AIP)
The Autoimmune Protocol is a stricter form of the paleo diet, popularized in the 2010s by author and researcher Dr. Sarah Ballantyne and others. For an elimination phase of several weeks or more, it removes grains, legumes, dairy, eggs, nuts, seeds, nightshades (tomatoes, peppers, potatoes, eggplant), coffee, alcohol, refined sugar and additives, leaving meat, fish, organ meats, vegetables, fruit, healthy fats and fermented foods. Foods are then added back one at a time, like a careful detective following clues, to find personal triggers.
Strengths
- Small studies found improvements. In one study of people with inflammatory bowel disease, most reached symptom remission; in a small study of women with Hashimoto's, symptoms and quality of life improved, though thyroid test results did not clearly change.
- Nutrient-dense whole foods, including organ meats and fish.
- The reintroduction phase helps you learn your own triggers instead of avoiding foods forever.
Watch out for
- The studies were very small and had no comparison group.
- Very restrictive, so it is easy to fall short on calories, fiber and calcium.
- Some people stay in elimination too long, out of fear, and their list of foods keeps shrinking. Elimination is meant to be a doorway, not a home.
- Costly, socially isolating, and not a replacement for medical treatment. The office potluck can start to feel like an obstacle course.
Eating well within it
- Eat a wide range of vegetables, including sweet potatoes, squash, root vegetables and leafy greens, for fiber and energy.
- Include oily fish and, if you can, liver about once a week.
- Use canned fish with soft bones (sardines, salmon) and leafy greens for calcium. The bones are the point.
- Plan your reintroductions from the start, with a clear timeline on the calendar.
Possible supplement needs
Calcium and vitamin D, since dairy and eggs are removed.
Who should be careful
Children, pregnant women, and anyone underweight or with a history of eating disorders. It works best with a guide who knows the protocol well.

No. 68Low-FODMAP Diet
FODMAPs (Fermentable Oligosaccharides, Disaccharides, Monosaccharides And Polyols, which is why everyone just says FODMAPs) are short-chain carbohydrates that gut bacteria ferment, which can cause gas, bloating and pain in sensitive people. Researchers at Monash University in Melbourne developed the low-FODMAP diet for irritable bowel syndrome. It has three steps: cut high-FODMAP foods (such as wheat, onion, garlic, beans, some fruits, milk and sugar alcohols) for about two to six weeks; reintroduce them group by group; then eat as varied a diet as you can.
Strengths
- One of the best-studied diet approaches for IBS; many people in clinical trials had less bloating, pain and gas.
- Personal: the reintroduction step shows which foods matter for you, not for your neighbor.
- Monash University tests foods and publishes the results in an app, which makes the diet easier to follow. Finally, a phone app that earns its place.
Watch out for
- It is meant to be short-term. Staying in the strict phase too long can lower fiber and reduce helpful gut bacteria.
- It is not a general healthy-eating or weight-loss diet, however trendy it sounds, and it is not for people without gut symptoms.
- IBS-like symptoms can come from celiac disease, inflammatory bowel disease and other conditions, so get a diagnosis first (and a celiac test before cutting wheat).
- "Low-FODMAP" packaged foods can be highly processed. A new label on the same old snack is still the same old snack.
Eating well within it
- Work with a dietitian trained in the diet; it is easy to get wrong alone.
- Use garlic-infused oil and the green tops of spring onions for flavor without the FODMAPs. Clever, and delicious.
- Build meals from oats, rice, quinoa, potatoes, carrots, zucchini, oranges, strawberries, lactose-free yogurt and hard cheeses.
- Small portions of canned, rinsed lentils or chickpeas are often tolerated.
Possible supplement needs
Usually none if the diet stays varied. Calcium if dairy is cut out completely.
Who should be careful
Children, people who are underweight, and anyone with a history of eating disorders need professional support. Blood in the stool or unplanned weight loss needs a doctor first.

No. 69Gluten-Free Diet
A gluten-free diet removes gluten, a protein in wheat (including spelt), barley and rye, and in foods made from them, such as bread, pasta, beer and malt. For people with celiac disease, an autoimmune condition in which gluten damages the small intestine, it is the only accepted treatment and must be followed strictly for life. Others avoid gluten because of wheat allergy, non-celiac gluten sensitivity, or a belief that it is healthier, a belief the snack industry is happy to encourage.
Strengths
- For celiac disease, it lets the gut heal and lowers the risk of long-term problems such as anemia and bone loss.
- Many people with non-celiac gluten sensitivity report fewer gut symptoms, less tiredness or fewer headaches.
- Plenty of whole foods are naturally gluten-free, no label needed. Nobody ever had to certify a carrot.
Watch out for
- Test for celiac disease before going gluten-free. Blood tests and biopsies are only accurate while you are still eating gluten.
- Gluten-free breads and snacks are often refined starch, sugar and additives, and they cost more. They are often not enriched, so B vitamins, iron and fiber can run low. A gluten-free cookie is still a cookie.
- With celiac disease, even crumbs matter: shared toasters, fryers and cutting boards can cause harm, and regular oats are often cross-contaminated.
- Some studies suggest that in some people, symptoms come from other parts of wheat, such as fructans (a FODMAP), rather than gluten itself.
Eating well within it
- Base meals on meat, fish, eggs, beans, vegetables, fruit and potatoes rather than packaged substitutes.
- Choose whole-grain options: brown rice, quinoa, buckwheat, millet, amaranth and certified gluten-free oats.
- Read labels for hidden gluten in soy sauce (try tamari), malt, soups and sauces. Gluten is a master of disguise.
Possible supplement needs
Iron, folate, vitamin B12, vitamin D and calcium are often low at celiac diagnosis; they are worth testing, and a gluten-free multivitamin helps.
Who should be careful
Anyone who suspects celiac disease should be tested before cutting gluten. People with celiac disease should ask their pharmacist whether their medicines and supplements are gluten-free.
No. 70Low-Histamine Diet
Histamine is a natural chemical involved in immune reactions and digestion. Some people seem to react to histamine in food with headaches, flushing, itching, hives, a stuffy nose or gut upset, called histamine intolerance; one theory is low activity of DAO (diamine oxidase), the enzyme that breaks down histamine in the gut. The diet favors fresh foods and avoids aged cheese, cured and smoked meats, canned or smoked fish, fermented foods, vinegar, wine, beer, leftovers, and some produce such as tomatoes, spinach and citrus. Yes, even leftovers: freshness is the whole game here.
Strengths
- A short, supervised trial can help some people link symptoms to specific foods.
- Encourages fresh, home-cooked whole foods over anything that has been sitting around.
- Small studies suggest some people with suspected histamine intolerance have fewer symptoms.
Watch out for
- Histamine intolerance is hard to pin down. There is no reliable single test, and symptoms overlap with allergies, IBS and other conditions.
- Food lists disagree from source to source, because histamine levels change with freshness, storage and ripeness. The same food can change its tune as it sits.
- Too restrictive to follow long-term; it cuts out many healthy foods, including fermented foods.
- Severe reactions (throat swelling, trouble breathing, fainting) need emergency care and allergy testing, not a diet.
Eating well within it
- Cook fresh meat and fish, and freeze leftovers right away instead of keeping them in the fridge. Your freezer becomes your best friend.
- Flavor food with fresh herbs and olive oil instead of vinegar, soy sauce and aged cheese.
- Keep a symptom diary, and after a few weeks reintroduce foods one at a time, like a patient detective.
Possible supplement needs
DAO enzyme supplements, taken with meals, are sold for histamine intolerance, but the evidence is limited, so treat them as an experiment, not a cure.
Who should be careful
People with possible mast cell disorders or severe allergies should see an allergist or immunologist. Anyone losing weight or eating very few foods needs professional help.
No. 71Gerson Therapy
Dr. Max Gerson, a German-born physician who later practiced in New York, developed this regimen in the first half of the 1900s, first for migraines and tuberculosis and later for cancer; the Gerson Institute, founded by his daughter Charlotte, promotes it today. It includes about 13 glasses a day of fresh organic vegetable and fruit juice (roughly one an hour), a salt-free plant-based diet, coffee enemas several times a day, and supplements such as potassium, iodine, thyroid extract and pancreatic enzymes. If you or someone you love is weighing it, you deserve clear facts, so here they are.
Strengths
- Emphasizes fresh vegetables, fruit and whole plant foods, and cuts out processed food, alcohol and tobacco.
- Many followers value the sense of taking an active part in their own care, and that wish deserves respect.
Watch out for
- There is no reliable evidence that Gerson therapy works against cancer; major cancer organizations have found no good studies showing benefit.
- Coffee enemas can cause dangerous salt and mineral imbalances, dehydration, bowel injury and infection; deaths have been reported.
- Low protein and calories can worsen weight and muscle loss in people already weakened by cancer.
- Very demanding and costly; hourly juicing often needs a full-time helper.
- Delaying or refusing proven treatment can let a treatable cancer spread.
Eating well within it
- If you value its focus on fresh produce, eat more vegetables, fruit and beans alongside medical cancer care, and tell your oncology team what you are doing.
- Do not use coffee enemas.
- Get enough protein and calories; a dietitian who specializes in cancer can help.
- During chemotherapy or with weak immunity, ask whether unpasteurized juice is safe for you.
Possible supplement needs
Never take the protocol's supplements, especially thyroid extract and potassium, without medical supervision. Review every supplement with your oncology team, since some can interfere with treatment.
Who should be careful
Anyone with cancer: this regimen must never replace medical cancer care. People with heart or kidney disease or weakened immunity, children, and pregnant women face special risks.
No. 72Wahls Protocol
Dr. Terry Wahls, a physician at the University of Iowa, was diagnosed with multiple sclerosis (MS) in 2000. She reports that within a few years she needed a tilt-recline wheelchair, and that after redesigning her diet, along with exercise and electrical muscle stimulation, she could walk and ride a bike again. Her modified paleo protocol asks for up to nine cups of vegetables and fruit a day (three each of leafy greens, sulfur-rich vegetables such as cabbage and onions, and deeply colored produce), plus organ meats, seaweed, grass-fed meat and wild fish. Its stricter levels remove grains, dairy, eggs and legumes.
Strengths
- Extremely rich in vegetables, fiber, vitamins, minerals and omega-3 fats. Few diets out-green this one.
- Small studies by her team found less fatigue and better quality of life; a trial comparing it with the low-fat Swank diet found fatigue improved on both.
- Her story inspires many people with MS to take an active role in their own health.
Watch out for
- Studies are small and short; there is no proof that it slows MS or replaces disease-modifying treatment.
- One person's recovery cannot predict another's; MS varies widely and can have long quiet periods on its own.
- Nine cups of produce a day is a lot; some people get bloated or struggle to eat enough. That is a serious amount of chewing.
- Seaweed can supply too much iodine, and liver is very high in vitamin A. Here, more is not always better.
Eating well within it
- Spread the nine cups across the day: greens in a smoothie, a big salad at lunch, cooked cabbage or onions at dinner.
- Mix small amounts of liver or heart into ground meat or stews, where they blend in quietly.
- Use seaweed sparingly, such as a sprinkle of flakes.
Possible supplement needs
Vitamin D is often low in MS and worth testing; calcium matters too without dairy.
Who should be careful
People on blood thinners (greens are high in vitamin K), people with thyroid conditions or kidney stones, and pregnant women (vitamin A in liver). Use it alongside, not instead of, medical MS care.
No. 73Whole30
Whole30 was created in 2009 by Melissa Urban (then Melissa Hartwig) and Dallas Hartwig. For 30 days you remove added sugar (real or artificial), alcohol, grains, legumes (including soy and peanuts), dairy and certain additives, and you don't recreate treats like pancakes with "approved" ingredients or weigh yourself. No sneaking dessert in through the side door. You eat meat, seafood, eggs, vegetables, fruit, nuts and natural fats. Then you add foods back one group at a time to see how each affects you.
Strengths
- A 30-day experiment is easier to commit to than a lifelong diet. Almost anyone can circle a month on the calendar.
- Cuts out added sugar, alcohol and ultra-processed food, and gets people back in the kitchen and out of the drive-through.
- Reintroduction can show which foods affect your energy, sleep, digestion or skin.
Watch out for
- There is little formal research on Whole30 itself; most support comes from personal stories, not studies.
- Whole grains, beans and dairy are healthy for most people, so there is no need to avoid them long-term without a reason.
- Weight lost usually comes from eating less and often returns with old habits; long-term results depend on what you keep doing after the month ends.
- Many people skip or rush the reintroduction, which is the main point. That is like walking out of the movie before the ending.
- The strict, all-or-nothing rules may not suit people with a history of disordered eating.
Eating well within it
- Fill your plate with vegetables, a palm-sized portion of protein, and olive oil, avocado or ghee (allowed, since its milk solids are removed).
- Use sweet potatoes, squash and fruit for energy.
- Eat canned salmon with soft bones and leafy greens for calcium.
- Plan reintroduction before you start: add back one food group, then pause a couple of days and notice changes.
Possible supplement needs
Usually none for 30 days. Calcium and vitamin D if you stay dairy-free longer.
Who should be careful
Pregnant women, people with a history of eating disorders, and people taking insulin or other diabetes medicines, whose blood sugar can drop as carbohydrate intake falls.
