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.

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.

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.

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.
