The mistakes that block weight loss are often invisible: uncounted bites, sugary drinks, over-generous portions of the "good" foods, meals never planned. This article re-reads twelve of those habits in the light of the eleven rules of Nidam al-Tayyibat, the eating system described by Dr Diaa Al-Awadi, which does not count calories but puts its finger on each of them, alongside the view of conventional nutrition.
The system does not present itself as a slimming diet; its rules and its palette, as the guide and the site's food database document them, serve here as a reading grid, not as a promise.
One point first: no one has measured in published work whether this system makes you lose weight. It removes bread, processed products and sugary drinks, but it adds rice, butter, dates and sugar. Medical institutions dispute several of its positions, daily sugar first. A person with diabetes, pregnant, on treatment or carrying significant excess weight does not apply it without their doctor.
Mistake 1: underestimating what you actually eat

The spoonful tasted while cooking, the date nibbled while the rice cooks, the end of the dish finished while clearing the table: none of that shows up when you tally your day. The system's two-hour rule makes those occasions visible: once a meal is over, at least two hours must pass before any new eating occasion, and every bite restarts the counter. According to the method, tasting while cooking is an eating occasion.
How to correct it without becoming obsessive
The system does not ask you to write down what you eat, but to group everything eaten into the meal — dessert, fruit and tea included. An alarm set two hours after the last bite is enough for the first few days. Conventional nutrition reaches the same conclusion: uncounted eating occasions often weigh more than the meals.
Mistake 2: changing everything at once
Cutting out bread, dairy, poultry and salads in a single week is the surest way to give up in the second. The system's sources all advise against changing everything at once: the transition runs over four weeks, one food family per week. They warn that the first week may come with fatigue or headaches; conventional nutrition would see in that the effect of an abrupt change of intake. A symptom that persists is a matter for the doctor.
Mistake 3: turning meal spacing into a fast
The two-hour rule sets a minimum spacing, not a number of meals, and not a target to stretch indefinitely: the method does not ask you to skip meals. The voluntary fasting the doctor recommended, within his religious framework, is another subject, contraindicated or to be supervised in case of treated diabetes, pregnancy, breastfeeding, kidney or liver disease, in children and in older people.
Mistake 4: eating because it is time
The system's third rule asks you to eat only when hunger is real and physical, not out of habit, boredom or stress. Eating three meals a day "because it is time" is described by its sources as a needless burden. The fourth rule completes it: stop "20% before total satiety", or "leave a quarter of the plate". Together, they replace all portion counting in the system.
Mistake 5: drinking your calories without noticing

The system sets aside sodas (red), energy drinks (red) and industrial juices (red). The drinks it admits are few:
- still water (green), its base drink, taken by thirst, with no quota;
- green tea (green, without milk) and mint tea (green);
- coffee (green), provided it is drunk without milk or creamer.
Two nuances the food database itself adds. The mint tea entry recalls that it is the usual amount of sugar in Moroccan tea that deserves attention: a very sweet tea at every meal is admitted by the method, but counted by conventional nutrition. And fruit juices (yellow) are admitted by the system; for conventional nutrition, a juice concentrates the sugars and loses the fibre, and whole fruit is preferable. A glass of water and a lightly sweetened mint tea satisfy everyone.
Mistake 6: underestimating portions of the "good" foods

This is the most common mistake among people discovering the palette. According to the system, the green zone indicates a frequency allowed day to day, not an unlimited quantity. Crisps (green) are admitted by the system, but conventional nutrition files them among the fried, calorie-dense foods to limit. Qechta (green) is a very fatty cream reserved elsewhere for occasional use; halva (green) is rich in sugar and fat; honey (green) remains a free sugar; butter (green) is a saturated fat to limit according to classical nutrition.
The measure is in the condition
Several entries carry their own guard rail:
- dates (green) are marked "1 to 6 a day according to the system";
- almonds (yellow) and walnuts (yellow), "in measure, plain and unsalted";
- olives (orange), "in small quantity".
For the rest, stopping before satiety is the system's only measure. Anyone trying to lose weight reads, on every entry, the "classical nutrition view" line as much as the zone dot.
Mistake 7: mixing two logics
Building your plate from the "good" foods of both worlds gives a result that matches neither. The system files in the red zone foods conventional nutrition recommends: oats (red), brown rice (red), quinoa (red), avocado (red), yoghurt (red), legumes (red). Conversely, it places white sugar, butter and crisps in the green zone. Classical nutrition recognises none of the principles that ground those exclusions. Better to know which logic you are following.
Mistake 8: underestimating the impact of sleep and stress

The documented sources of the system say nothing about sleep. They approach stress from a single angle, that of the third rule: do not eat under the effect of stress, boredom or habit, but only when hunger is real.
Gentle leads
Conventional nutrition, for its part, holds lack of sleep and chronic stress to be factors that encourage snacking, independently of what is on the plate. The two readings meet on one simple gesture: before eating outside a meal, ask whether the hunger is real, drink a glass of water, wait a quarter of an hour. On sleep, this article has nothing to draw from its sources.
Mistake 9: confusing exercise with real expenditure

The system's tenth rule asks for daily movement: a daily walk or simple exercises, with no brutal sports programme in the first week. The system links that movement to what it calls "internal combustion", vocabulary of its own that no institution has validated. Nowhere does it say that a sports session allows you to eat more. Conventional nutrition warns against the same reflex: effort is often overestimated, and the "reward" that follows easily erases it.
Mistake 10: expecting results in two weeks
According to the method, "real results" show after three to six months; the site's guide takes up no promise of a result, but keeps the idea: the system is conceived as a way of life, not as a cure. Changing method every two weeks makes it impossible to evaluate anything, and weight varies day to day for reasons that have nothing to do with fat.
Mistake 11: weighing yourself every day
The system does not ask for a daily weigh-in. One source suggests weighing once a week, a photo every two weeks and a few lines on how you feel. The guide adds a common-sense instruction: also note what is going wrong — persistent fatigue, dizziness, unusual thirst — and tell the doctor about it.
Mistake 12: not planning meals in advance

When introducing the "one day yes, one day no" alternation for animal protein, the system's sources insist on planning the week on a sheet of paper, with the "yes" and "no" days, before doing the shopping. With no plan, you fall back on whatever is there: bread, a ready-made dish.
What planning changes in practice
The site's programme offers a simple marker from the first week: prepare a "starch base", a pot of cooked rice (green) and boiled potatoes (green) in the fridge. The shopping list is then organised by aisle:
- for "yes" days, a sea fish (green) and sardines (yellow, fresh);
- for vegetables, squash (green, cooked) and courgettes (yellow, cooked);
- for fruit, apples (green, peeled for preference), grapes (green) and strawberries (green);
- for meat-free evenings, an aged cheese such as kashkaval (green).
Planning does not make you lose weight in itself, but it is the condition of every other correction.
Which rule of the system answers each mistake?
For each mistake, the Nidam al-Tayyibat rule concerned and what conventional nutrition takes from it.
| Mistake | Rule or position of the system | Conventional view |
|---|---|---|
| 1. Uncounted bites | two-hour rule: every bite restarts the counter | eating outside meals often weighs more than the meals |
| 2. Changing everything at once | four-week transition, one food family per week | abrupt change of intake; a lasting symptom means a consultation |
| 3. Spacing turned into fasting | two hours is a minimum, not a target | fasting contraindicated in treated diabetes or pregnancy |
| 4. Eating by the clock | third rule: real hunger only; fourth: stop before satiety | useful markers, but no guarantee on quantity |
| 5. Drinking your calories | sodas, energy drinks and industrial juices red zone | agreed; the sugar in tea and fruit juices count too |
| 6. Portions of the "good" foods | the zone gives a frequency, the entry's condition the measure | crisps, qechta, halva, butter and honey remain to be limited |
| 7. Mixing two logics | oats, quinoa, avocado, yoghurt, legumes red zone | those foods are recommended; the exclusions are not recognised |
| 8. Sleep and stress | do not eat under stress; nothing on sleep | lack of sleep and chronic stress encourage snacking |
| 9. Exercise versus expenditure | tenth rule: walk every day, with no food reward | effort is often overestimated |
| 10. Results in two weeks | three to six months according to the method, with no published data | judge in weeks, not in days |
| 11. Daily weigh-in | one weigh-in per week according to one source | weight varies day to day, not only with fat |
| 12. No planning | plan the "yes" and "no" days before shopping | the condition of every other correction |
Frequently asked questions
Is Nidam al-Tayyibat a diet for losing weight?
No. It presents itself as a philosophy of the body, not as a slimming diet, and counts neither calories nor portions. No one has measured its effect on weight in published work, and the site reports no testimonial and no figure.
What is the most common mistake among beginners?
Believing that "green zone" means "as much as you like". According to the system, the zone indicates a frequency; the entry's condition and stopping before satiety give the measure. Crisps, qechta and halva are admitted by the system, but limited by classical nutrition.
Can these tips be followed by someone with diabetes or on treatment?
Not without their doctor. The system places white rice, dates and sugar among its daily pillars, which medical institutions judge risky for people with diabetes, and changing the rhythm of meals can interfere with a treatment, which is never modified or stopped because of an eating method.
Should calories be counted on top of the system's rules?
The system does not provide for it. If the goal is weight loss, a dietitian can estimate needs and intake at the start; that is a step outside the method, which does not rule it out.
How long before judging?
The system's sources speak of three to six months, with no published data behind it. Conventional nutrition also reasons in weeks rather than days. One weigh-in a week is enough.
