First, to open the child's appetite, give them cod liver oil for a period of three months in syrup form, in the morning (or capsules for an adult).
In addition, prepare a mixture with 50 grams of almonds and hazelnuts, 50 grams of sesame seeds, 100 grams of ground fenugreek, and 1 kilogram of honey, which the child will consume throughout the day.
What the science says: in children, weight
What published research says about the remedies mentioned above, for context only — the studies address material causes, while healing belongs to Allah.
In children
In infants, the probiotic Lactobacillus reuteri reduces colic-related crying according to a meta-analysis (Pediatrics, 2018) (Acta Paediatr, 2024); in children, honey soothes nighttime cough (after one year of age) (Cochrane, 2018), fiber and hydration treat constipation (J Pediatr, 2022), and omega-3s are being studied for hyperactivity (Neuropsychopharmacology, 2018). Precaution: never give honey before one year of age, no essential oils before age 3 (age 6 for peppermint), doses adjusted to weight; any fever in an infant under 3 months is an emergency.
Weight
The Mediterranean diet (olive oil, vegetables, legumes, fish, few processed foods) is among the most effective and sustainable approaches for weight according to network meta-analyses (Clin Nutr ESPEN, 2024) (BMJ, 2020); intermittent fasting contributes to it (BMJ, 2025). The hadith of "a third for food, a third for drink, a third for air" remains the best rule. Precaution: be wary of "fat burners" and very restrictive diets; unexplained weight loss should be investigated.
