The system
01What is the Tayyibat system?
Tayyibat means the good, pure and wholesome things in Arabic. The system, taught by Dr. Diaa Al-Awadi, sorts foods into two large families based on how the body digests and assimilates them. It does not count calories and does not measure portions. It rests on two golden rules: eat when hungry, eat to satiety then stop, and trust the type of food more than the quantity.
02Do I count calories?
No. The system explicitly rejects calorie counting. The doctor's principle is that the kind of food matters more than the amount, because two foods with the same caloric content can have wildly different hormonal effects.
03Is there a vegetarian version?
The system gives a central role to red meats and natural animal fats, so it cannot be reduced to a strictly vegetarian version without losing its core mechanism. It can however be adapted to lighter cycles, where protein days lean on fish and seafood instead of mammals.
04How does the system view intermittent fasting?
Favourably, as a natural extension of the two-hour rule. By spacing meals into one or two clean windows per day, the body multiplies its repair and combustion phases. The doctor saw fasting as one of the system's natural rhythms, not as a separate technique.
05What does the system say about stress?
Stress raises cortisol, which orders the liver to produce extra glucose in anticipation of a threat. This is why glycaemic readings can be elevated on stressful days even with a perfectly clean diet. The body is doing exactly what it should do.
06In which languages is the system documented?
The doctor taught primarily in Arabic. Tertiary educational sites have grown in Arabic, French and English. This site presents the system in five languages: English, Arabic, Spanish, French and Dutch.
07What is this site for?
To gather, structure and translate the public teachings of Dr. Diaa Al-Awadi on natural nutrition, in a respectful and faithful spirit. It is purely educational, intended for adults, and does not constitute medical advice.
08How fast does weight come off on Tayyibat?
Two phases. Week 1 to 4: visible water loss, 2 to 4 kg, depending on the starting point. Week 5 to 12: steady fat loss, 0.5 to 1 kg per week. Past three months: plateau or 1 to 2 kg per month if you stay disciplined on the two-hour rule. The system is slower than keto, faster than Mediterranean, and far more sustainable than either.
09What if my weight plateaus on Tayyibat?
Audit three levers. One: the two-hour rule, are you actually waiting two hours or sliding to 90 minutes? Two: the rest-day frequency, do you have at least one rest day per week with no animal protein? Three: the portion drift, are your portions still 200 g protein + 80 g grain, or have they crept up? Adjust the slackest lever, leave the others alone for a month, then reassess.
10How long before I see the first results on Tayyibat?
Day 3 to 5: digestion lighter, less bloating, sleep deeper. Week 2: clearer skin for many. Week 4: visible silhouette change, looser clothes. Week 6 to 8: stable energy curve through the day, no afternoon crash. The system is honest, no overnight miracle; the body needs three weeks just to recalibrate insulin and glucagon rhythms.
11Can I have cheat meals on Tayyibat?
Practically, yes, occasional. One meal outside the system every ten to fifteen meals does not break the rhythm if you return immediately. The system is more forgiving on cooking method or grain choice than on protein-protein or fresh dairy. Avoid the worst offenders: pork, alcohol, white sugar in soft drinks, fresh yogurt with added sugar.
Rules
01What is the two-hour rule?
Two hours after the last bite, insulin clears the bloodstream and the body shifts into repair and combustion. Stored fat starts being mobilised, growth hormone, glucagon, testosterone and cortisol come back to work. Eating again before the two hours are up restarts the digestive cycle and cancels the combustion phase.
02Why alternate protein days?
Daily animal protein keeps the digestive system in constant breakdown mode. Spacing protein days lets the gut rest, the liver regenerate, and the system find a more sustainable rhythm. The doctor recommended one protein day, then one rest day, repeated.
03Can I combine two proteins in the same meal?
No. The system forbids protein-protein combinations in a single meal: never lamb with fish, never beef with cheese, never fish with akawi. The digestive enzymes for one animal protein are different from those for another, and combining them overloads the system. One protein per meal, with grain and cooked vegetables on the side.
04Is there a limit on the number of ingredients per recipe?
Yes. The rule of thumb is three main ingredients maximum per dish, not counting salt, ghee or butter, the cooking fat and the cooking water. A Tayyibat plate looks like: lamb, rice, cooked pumpkin. Or: wild fish, freekeh, cooked tomato. Adding a fourth main ingredient usually starts to break the digestive logic.
05Is there a recommended order for eating within a meal?
Yes, lightly. Start with a couple of dates and a sip of water if breaking a fast, then a spoon of the cooked vegetable. Then the protein-grain pairing. Optional: a small bite of cheese or a date at the very end. Avoid liquid during the meal, especially cold water. Tea or coffee, if any, come twenty minutes after.
06Can I drink water with my meal?
Minimal. The system asks you to drink before the meal (a glass of water 15 to 30 minutes before) and to stop drinking during the meal. A small sip is OK. Drinking large amounts during a meal dilutes the gastric acid and slows digestion. Wait one to two hours after, then drink freely.
07Can I snack between meals?
No. Snacking breaks the two-hour combustion window, the central mechanism of the system. If you are hungry between meals, drink water, green tea or unsweetened Arabic coffee. If real hunger persists, eat a small Tayyibat-compatible meal (three dates, or a date with ghee) and reset the two-hour clock from there.
Foods
01Why is chicken excluded?
According to the doctor's reading, chicken triggers a histamine release that exceeds digestive needs, especially in industrially raised birds. The system replaces it with red meats from the lamb and beef families, plus pigeon, quail, rabbit and crab.
02Why are eggs excluded?
Eggs are placed in the khabaith family because they would contribute to excessive histamine release and to symptoms reported as morning swelling, bloating or skin reactions. The system suggests dairy fats (cream, ghee) and tahini for similar morning richness.
03Why is fresh milk excluded but cheese is allowed?
Liquid lactose loads the digestion in a way fermented or aged products do not. Cheddar, mozzarella, parmesan and similar aged cheeses lose much of their lactose during ageing, which is why the system tolerates them.
04Why are raw vegetables not encouraged?
The doctor's reading suggests raw fibre creates a slow digestive overload, especially in already inflamed guts. Cooked vegetables (pumpkin, taro, potato, mushroom) are favoured because they pass through the digestive tract more easily.
05Why are watermelon and cantaloupe excluded?
Their water-to-sugar profile creates a fast glycaemic spike followed by a strong insulin response. The system prefers fruits with denser flesh and slower digestion, like apple, pear, pomegranate or persimmon.
06Can I eat tomato in the Tayyibat diet?
Yes, but only in Attaybatte preparation: peeled, deseeded and cooked, the three conditions are cumulative. In the strict Tayyibat palette, raw tomato in salads remains excluded. The cooked Attaybatte tomato becomes a versatile base for sauces, kabsa, tagines and saffron rice. To prepare: score a cross at the base, blanch sixty seconds in boiling water, peel, halve and scoop out the seeds, then cook in olive oil or ghee at least ten minutes.
07Is onion allowed in the Tayyibat system?
Yes, but only when cooked. Raw onion in a salad remains excluded. The official preference is to chop the onion very finely or blend it before adding it to the pan, so that it dissolves into the sauce rather than staying as visible chunks. This serves two purposes: easier digestion (no fibrous bite to break down) and better aromatic integration with the meat or rice. Practical example: blend two medium onions raw with a little water, then pour into the pot at the start of any slow-cooked lamb tagine or rice dish.
08Is garlic allowed in the Tayyibat system?
No. Garlic was previously a gray-zone item but the strict Tayyibat palette places it definitively in the khabīth (excluded) list. The reasons cited are the strong histamine release at digestion, the gut-lining irritation profile, and the same allium-family logic that already excludes raw onion. Recipes that traditionally use garlic need a substitute: aromatic blends with green cardamom, saffron, thyme and a touch of marinated lemon, which provide depth without the histamine load.
09Is raw bell pepper tayyib or khabīth?
Raw bell pepper is khabīth (excluded). The Tayyibat palette specifies that bell pepper is tayyib only when cooked: roasted, sautéed, or simmered. Raw bell pepper in salads or crudités remains excluded for the same reasons as before: nightshade-family irritants, difficult cellulose. Cooked bell pepper, on the other hand, becomes an excellent side: roasted whole at 200 °C twenty minutes, peeled and torn, then dressed with olive oil, salt and thyme.
10Are lentils tayyib or khabīth?
Lentils are khabīth in the system, along with chickpeas, fava beans, peanuts and other legumes. The reasoning is digestive load: legume proteins ferment in the colon, and their anti-nutrients (phytates, lectins) interfere with mineral absorption. Tayyibat sources its protein from lamb, goat, beef, liver and wild sea fish, with grains (rice, freekeh, whole couscous) on the carbohydrate side.
11Is cucumber tayyib or khabīth?
Cucumber is khabīth. The system excludes most raw vegetables that travel through the gut largely intact: cucumber, lettuce, parsley, coriander, celery, raw carrot. Their cellulose mechanically irritates without yielding nutrients in the Tayyibat reading. They are not replaced by anything; the cooked-vegetable family covers the side of the plate.
12Is apple tayyib?
Yes. Apple is tayyib in the fruit ranking of the system, around eighth position (after dates, figs, grapes, guava, banana, pomegranate, pear). Eat it whole with the skin if organic, peeled if industrial. Best between meals during the combustion phase, not stacked at the end of a meal.
13Is cumin tayyib?
Cumin is khabīth. The allowed spice palette is short and specific: salt, green cardamom, saffron, thyme, green anise. Cumin, cinnamon, black pepper, paprika, sumac, turmeric, ginger, cloves, nutmeg, oregano, rosemary are all excluded by the system. The corollary is a quieter flavour profile, which the system trades for digestive lightness.
14Is pasta tayyib?
Pasta is khabīth. The grain side of the plate is rice, freekeh, whole-wheat couscous (Moroccan tradition) and sourdough whole bread. Refined wheat pasta is excluded. White bread is also excluded for the same reason: the refinement strips away bran and germ, leaving behind a fast-glycemic load.
15Is yogurt tayyib?
Yogurt is khabīth in the Tayyibat reading, like fresh milk and fresh white cheese. The allowed dairy is the aged family: akawi, kashkaval, halloumi, parmesan, cheddar, mozzarella, plus ghee and butter. The ageing breaks down lactose and casein structures, leaving a cheese that the system considers digestively friendlier than fresh dairy.
16Are shrimp and squid tayyib?
Shrimp, squid and crab are khabīth. The only seafood accepted by the system is wild sea fish: sardine, mackerel, sole, sea bass, hake, tuna, white fish. Bottom-feeders and shell-bearers (shrimp, crab, mussels, squid) are excluded due to bioaccumulation concerns and the doctor's reading of the Qur'anic principle of tayyibat.
17Is honey tayyib?
Yes. Raw, unfiltered honey is tayyib and recommended as the system's only sweetener. Pairs naturally with dates, ghee, qishta and Arabic coffee at suhoor or breakfast. Industrial filtered honey heated above 40 °C loses its enzymes and falls toward the khabīth side. Buy single-origin raw honey when possible.
18Is coffee tayyib?
Black coffee, unsweetened, is tayyib and allowed at any time, including during the two-hour combustion window. Arabic coffee with green cardamom is the system's preferred form. Sugar in coffee makes it khabīth. Milk in coffee makes it khabīth. Black coffee or Arabic coffee, no sugar, no milk, that is the line.
19Is green tea tayyib?
Green tea is tayyib, plain, no sugar, no milk. Black tea and red tea are also accepted under the same condition. Sweet Moroccan mint tea with sugar slabs is not Tayyibat-compatible in its sweetened form; brew the same tea without sugar and it becomes tayyib. Same logic for Egyptian shay bil-laban: drop the sugar and the milk.
20Is chocolate tayyib?
Industrial chocolate with refined sugar, milk powder, lecithin, vegetable oils is khabīth. Dark chocolate 85 % cocoa or higher, with only cocoa and a little raw sugar, is borderline and accepted in very small portions occasionally, never daily. The system stays cautious here: cocoa itself is roasted, sugar is a refined input, and the digestive load is real.
21Is watermelon tayyib?
Watermelon is khabīth in the system. The combination of very high free water, fast sugars and weak digestive density places it in the same bucket as cantaloupe, melon and other watery fruits. Replace it with dates, figs, grapes, pomegranate during summer when hydration is the question; replace it with green tea for cooling.
22Is pizza tayyib?
Industrial pizza is khabīth: refined-flour dough, fresh mozzarella, processed tomato sauce, oregano, plus protein-protein combinations (cheese + meat). Home-made on whole sourdough, with Attaybatte tomato sauce, akawi instead of fresh mozzarella, lamb sausage instead of pork salami, and no oregano can pass as a rare occasional dish, but it stops being pizza in the usual sense.
Practical
01How is beef supposed to be cooked?
Always boiled long first, then seared in ghee. The doctor's method draws impurities out in the boiling phase, then concentrates the flavour in the searing phase. Direct grilling or dry oven cooking are not the system's preferred routes for beef.
02Is the system compatible with Ramadan?
Yes. The fasting window of Ramadan is in fact a long form of the two-hour rule. The doctor recommended starting iftar with dates and a moderate amount of pure fat (ghee or olive oil), then a balanced meal of one protein and one grain. Suhur should remain light and free of khabaith.
03How much water should I drink per day?
There is no fixed daily quota. The doctor's rule is simple: drink when you are thirsty. Forced drinking burdens the kidneys without serving the body's actual needs. Listen to the thirst signal, and let renal regulation work.
04Can the system help with weight loss?
Followers commonly report progressive weight loss, attributed by the system to the daily two-hour combustion windows and the absence of insulin spikes from refined flour. The doctor framed weight loss as a side effect of metabolic order, not a starting goal.
05Should I check with my physician before starting?
Yes. This site is informative and educational. Any change of diet, particularly with an existing condition or ongoing medical treatment, requires a prior consultation with your physician. Their advice prevails over anything written here.
06Is the system suitable for children?
This site is intended exclusively for an adult audience. Pediatric nutrition follows specific medical principles and must always be discussed with a pediatrician. Nothing on this site replaces a pediatric consultation.
07Do I need supplements?
The system rests on whole foods, animal fats and traditional grains, which together cover most micronutrient needs according to its principles. It does not push supplementation. As always, your physician is the only one who can prescribe specific supplementation if you need it.
08What about exercise?
The fourth pillar is explicit: daily movement matters. Walking is enough to start. Heavy exercise on protein days is fine. On rest days, the doctor preferred low-intensity activity, leaving the body free to use its repair phases.
09What is the Pulse on the site?
It is the visual companion of the two-hour rule. Press Start 2h after a meal, and a thin gold line at the top of the page progresses for two hours. When it completes, a discreet message reminds you that combustion mode has begun.
10How do I start Tayyibat the right way?
Day one: empty the kitchen of khabaith staples (refined bread, industrial yogurt, chicken, eggs, lentils, cumin, cinnamon). Day two to three: stock up on tayyibat anchors (rice, freekeh, lamb, wild fish, dates, ghee, akawi, sourdough, green cardamom, thyme). Week one: cook one recipe per day from the site, two-hour rule from breakfast. Week two: add the rest day. Week four: you are running the system.
11How do I stay on Tayyibat when travelling?
Travel kit: a small jar of ghee, a pack of dates, a bag of green cardamom, a small thermos. Restaurants: order a grilled lamb chop or a wild fish plus a rice or freekeh side, ask for the vegetables steamed with no garlic and no cumin. Skip the bread basket. Two-hour rule still applies, only the menu shifts. Hotels: lean on the breakfast buffet for akawi, olives, olive oil, dates, eggs you can skip.
12How do I order at a restaurant on Tayyibat?
Three-part order. First, the protein: grilled lamb, wild fish, or, if nothing else, beef boiled then seared. Second, the grain: rice or whole bread, never pasta. Third, the cooked vegetable: simmered tomato sauce, roasted aubergine, sautéed pumpkin. Refuse: oregano, cumin, paprika, raw salad, sauces with garlic or onion not blended. Salt and olive oil on the side, you season at the table.
13What is the ideal Tayyibat suhoor for Ramadan?
Three to five dates, a small bowl of qishta with raw honey, two slices of sourdough with ghee and akawi, olives, a cup of Arabic coffee with green cardamom, no sugar. Heavy enough for slow-release energy across the fasting day, light enough not to spike insulin. Skip the eggs, skip the white bread, skip the sweetened tea.
14What is the ideal Tayyibat iftar for Ramadan?
Open with three dates and a glass of plain water at the call to prayer. Wait ten minutes, do the prayer. Come back to the table for the main meal: rice with stewed lamb and cooked pumpkin, or freekeh with wild fish and Attaybatte tomato sauce. Cup of green tea fifteen minutes after, then the two-hour rule starts for the rest of the evening. No fried sambousek, no sweet desserts, no soft drinks.
15Is Tayyibat safe during pregnancy?
The site does not give individual medical advice. The principle of the system, dense whole foods, daily ghee, weekly liver, no refined sugar, no industrial food, is compatible with most pregnancies. The two-hour rule should be relaxed in pregnancy: eat when hungry, the body knows. Talk to your obstetrician before any change of diet, especially in the first trimester and in case of gestational diabetes.
16Is Tayyibat compatible with breastfeeding?
Yes for most. The system's natural fats (ghee, butter, olive oil, dates) support milk production better than industrial low-fat alternatives. Liver day delivers retinol, B12 and iron that breastfeeding draws from. Drop the two-hour rule and eat when hungry. Drink a lot of plain water, herbal teas without anise (sometimes flagged as reducing supply in some women). Watch your iron and consult the GP.
17Can children follow Tayyibat?
The site is designed for healthy adults. The system's tayyib foods (lamb, fish, rice, ghee, dates, akawi, sourdough, cooked vegetables) are excellent for children and form the bulk of traditional Arab family meals anyway. Drop the two-hour rule: kids eat when hungry, growth is non-negotiable. Avoid the khabaith fast foods, sodas, industrial sweets. Talk to a paediatrician for any restrictive plan.
18Is Tayyibat good for older adults?
Particularly well-suited. The system's anchor foods, lamb, liver, ghee, dates, are dense in protein, retinol, B12, iron, choline, all of which older adults often lack. The two-hour rule supports a slower digestion. Watch hydration (older adults under-drink), reduce salt slightly if blood pressure is an issue, talk to the GP for medication interactions especially around ghee and aged cheese (vitamin K and warfarin).
19Is Tayyibat good for type 2 diabetes?
Many readers report HbA1c reductions over three to six months. The two-hour rule supports glucose stability, the absence of refined sugar and industrial bread removes the worst glycemic spikes, the protein-grain pairing slows absorption. Critical: do not stop or change diabetic medication on your own. Talk to your endocrinologist and monitor glucose closely during the first six weeks of the system.
20Can athletes follow Tayyibat?
Yes. Adjust two levers. One: portions, lift the protein to 250-300 g and the grain to 100-120 g per meal during heavy training phases. Two: timing, move one of the meals to 60 to 90 minutes before training and one to 60 to 90 minutes after. The two-hour rule still applies between full meals, but training counts as a metabolic window of its own. Liver day stays weekly.
21Can Tayyibat be done vegetarian?
Not in its full form. The system rests on lamb, liver, beef, fish for protein anchoring, with ghee as the daily fat. Removing the animal pillar removes the core. A semi-vegetarian version (fish twice a week, no land meat) is possible. A strict vegetarian or vegan version diverges so much from the original that it stops being Tayyibat: consider Mediterranean diet instead.
