NEW! Ramadan Nutrition Framework for Patients with Diabetes #RAMADAN

A structured, evidence-based guide for healthcare professionals

• Ramadan fasting results in prolonged fasting hours followed by a compressed feeding window, which significantly alters glucose dynamics, hydration status, sleep patterns, and physical activity.
• In patients with diabetes, these changes increase the risk of:
  • Post-prandial hyperglycaemia (particularly after Iftar)
  • Late-day hypoglycaemia
  • Dehydration and electrolyte imbalance
  • Excess caloric intake and weight gain

Medical Nutrition Therapy (MNT) is central to risk mitigation during Ramadan and should be initiated 6–8 weeks pre-Ramadan, alongside risk stratification.

Core Objectives of Ramadan-Focused Nutrition Therapy

• During Ramadan, nutrition therapy aims to:
  • Ensure adequate caloric intake during non-fasting hours to reduce fasting-related hypoglycaemia
  • Optimise macronutrient balance and carbohydrate distribution to limit glycaemic excursions
  • Use meal timing, sequencing, and structure to improve glucose predictability
  • Integrate nutrition planning with comorbidities (e.g. hypertension, dyslipidaemia, renal disease)

The objective is metabolic stability: fewer hypoglycaemic events and fewer post-prandial hyperglycemias.

The Ramadan Plate Model

• The Ramadan Plate provides a visual and practical framework for structuring meals without restricting cultural food choices.
• Recommended distribution at main meals (Suhoor and Iftar):
  • ½ plate non-starchy vegetables
    • higher in fibre = slower glucose absorption, improved satiety
  • ¼ plate protein
    • decreased post-prandial glycaemia, preserves lean mass
  • ¼ plate carbohydrates
    • Choose lower-GI, higher-fibre sources
  • Small amounts of unsaturated fats
    • Improve meal satisfaction without excess caloric load
• Carbohydrates are included deliberately, not eliminated.

Iftar: Meal Sequencing and Glycaemic Control

• Following prolonged fasting, insulin sensitivity and counter-regulatory responses are altered.
• Recommended Iftar sequence:
• Fluids first (water or milk-based drinks)
  • this restores hydration, prepares gastric emptying
• Follow with a small carbohydrate portion (e.g. 2-3 dates, counted as CHO)
  • prevents excessive glucose surge
• Main meal structured using the Ramadan Plate
  • Include protein + fibre = buffer carbohydrate absorption
• Meal sequencing is a key determinant of post-Iftar glycaemic response.

Suhoor: Metabolic Preparation for the Fasting Day

• Suhoor composition has a direct impact on:
  • Late-day hypoglycaemia
  • Energy stability
  • Hunger and compensatory overeating at Iftar 
• Suhoor should:
  • Contain protein and fibre
  • Avoid large high-GI carbohydrate loads
  • Include fluids
  • Be consumed as late as practically possible
• Carbohydrate-only or early Suhoor meals increase fasting risk.

Nutrition-Related Risk Patterns Observed During Ramadan

• Common patterns associated with glycaemic instability include:
  • Excessively large Iftar meals
  • High intake of refined carbohydrates and added sugars
  • Sugar-dense desserts after Iftar
  • Frequent evening snacking
  • Rapid eating, impairing satiety signalling
  • High-GI, low-protein Suhoor meals
  • Increased frying and saturated/trans-fat intake
  • Reduced physical activity and disrupted sleep
  • These patterns are predictable and modifiable through structured counselling.

Hydration Considerations

• Encourage consistent fluid intake between sunset and dawn
• Prioritise water and unsweetened beverages including dairy
• Limit sugar-sweetened and caffeinated drinks
• Pair fluids with meals/snacks to improve tolerance
• Dehydration increases the risk of hypotension, hyperglycaemia, and renal stress.

Macronutrient Targets (Evidence-Informed Ranges)

• Typical daily targets (individualised):
• Carbohydrate: ~45–50% total energy
• Protein: ~20–30% total energy (≥1.2 g/kg adjusted body weight)
• Fat: <35% total energy
• Saturated fat <10% Emphasis on MUFA/PUFA
• Fibre: ~20–35 g/day (≈14 g/1000 kcal)
• Higher fibre and adequate protein are associated with improved satiety and reduced post-prandial glycaemia.

Energy Distribution Across Ramadan Meals

• Typical allocation:
  • Suhoor: 30–40% total energy
  • Iftar: 40–50%
  • Snacks (if required): 10–20%

Physical Activity During Ramadan

• Light-to-moderate activity is generally safe
• Avoid prolonged or high-intensity exercise during fasting hours
• Post-Iftar activity is preferable
• Taraweeh prayers contribute meaningfully to daily energy expenditure
• Activity recommendations should be individualised based on risk stratification.

Criteria for Breaking the Fast (Clinical Safety)

• Patients should be advised to terminate fasting if:
• Blood glucose <3.9 mmol/L (70 mg/dL)
• Blood glucose >16.6 mmol/L (300 mg/dL)
• Symptoms of hypoglycaemia, hyperglycaemia, dehydration, or acute illness occur
• Breaking the fast under these conditions is medically indicated.
