In an authentic hadith, the Prophet ﷺ said: "The human being has never filled a vessel worse than the stomach. Yet it is enough for the son of Adam to have a few morsels of food to maintain his form, and if he cannot be content with that, then a third for food, a third for drink, and a third for breathing."
By nature, the human being tends to fill his stomach, sometimes to excess. The Prophet ﷺ, aware of this, reminds us that a small amount is enough to worship Allah.
During the sacred month of Ramadan, our habits and our rhythm change. There are three meals during this month: "Al-futur," the breaking of the fast after sunset; "al-'isha," a few hours after "al-futur"; and "as-suhur," before sunrise. For some, the meal is taken at a late hour, and the ideal is to have three regular meals and avoid snacking throughout the evening. And to avoid any risk of deficiency, it is important to diversify one's diet by combining the different food groups.
We can eat starchy foods such as rice, pasta, semolina, or sweet potato, which are sources of energy for the body and are essential to prevent excessive hunger or fatigue during the day.
In addition, fresh vegetables should be favored for their vitamin content, and fruit should be preferred for dessert.
As for meat, eggs, or fish, lean meats, eggs, and fish should be favored, cooked with little fat.
It is best to eat dairy products made from semi-skimmed milk, with just enough fat to cover our essential and vital needs. Olive oil should be used, and fried foods should be avoided to limit fat intake.
To avoid tiring the body, the consumption of sweets, chocolate, pastries, and sodas should be limited. A generous dessert can be enjoyed two to three times a week, and a small treat can be had daily at the end of a meal.
To reactivate the body without putting strain on it, the fast should be broken with dates, and hydration should come from water or fresh fruit juices. It should be noted that dehydration is the greatest risk during Ramadan, hence the importance of staying sufficiently hydrated during the permitted period, preferably with unsweetened drinks. Then, one should wait until the feeling of hunger decreases, and that is when one can sit down to eat.
Here is an example of a daily meal plan:
For breakfast: bread, jam, butter, yogurt, and cottage cheese, as well as an egg.
At the breaking of the fast: water, dates (three in number, to follow the Sunnah), and a glass of milk.
For dinner: a bowl of soup, starchy foods, meat, and occasionally oven-baked brick pastries filled with meat, fish, or shellfish. A portion of cheese, bread, and fruit should be added.
What the science says: fasting, vitamin D, hydration and heat
What published research says about the remedies mentioned above, for context — the studies address material causes, while healing belongs to Allah.
Fasting
Fasting, prescribed and then recommended by the Sunnah (Monday-Thursday, the white days), is now studied under the name intermittent fasting: a meta-analysis in the BMJ shows favorable effects on weight and cardiometabolic risk factors (BMJ, 2025), with an impact on appetite (Nutrients, 2023) and body composition (Diabetes Obes Metab, 2024). Precaution: people with diabetes on insulin, who are pregnant, breastfeeding, or in fragile health should adjust their fasting with their doctor — Islam permits, and sometimes requires, not fasting in case of illness.
Vitamin D
Vitamin D supplementation reduces the risk of acute respiratory infections, especially in people who are deficient, according to a meta-analysis in the BMJ (BMJ, 2017) updated since then (Lancet Diabetes Endocrinol, 2025); its deficiency is also linked to autoimmune diseases (Nutrients, 2023). Sunlight remains the primary source. Precaution: have your vitamin D levels tested before supplementing heavily — excess is toxic; common maintenance doses are safe.
Hydration and heat
Drinking enough water supports the kidneys and digestive transit (Am J Clin Nutr, 2022) and prevents urinary stones (Minerva Urol Nephrol, 2025); in very hot weather, water, water-rich fruits (watermelon, cucumber — dear to the professor), shade, and rest during the hottest hours prevent heatstroke. The Sunnah recommends drinking while seated, in three breaths, without excess ice. Precaution: infants, the elderly, and people with chronic illnesses dehydrate quickly; confusion, absence of urination, or a high temperature during a heat wave are warning signs.
