UAE Calorie & TDEE Calculator
Calculate your BMR, TDEE, and the exact daily calorie target for your goal — using the validated Mifflin-St Jeor formula with UAE lifestyle context.
To lose fat, eat 300–500 kcal below your TDEE. Your TDEE is your BMR (calories burned at rest) multiplied by your activity level. For a moderately active 80 kg male aged 30 at 180 cm, TDEE is approximately 2,760 kcal/day — meaning a fat-loss target of 2,260 kcal/day. Use the calculator below to get your personalised number.
Formula: Mifflin-St Jeor (1990). Results are estimates. Not medical advice.
How the calculator works: the Mifflin-St Jeor formula
This calculator uses the Mifflin-St Jeor equation, first published in 1990 and the most widely validated BMR formula for most adults. It is the formula recommended by the Academy of Nutrition and Dietetics as the preferred predictive equation for resting metabolic rate.
BMR — Male: (10 × kg) + (6.25 × cm) − (5 × age) + 5
BMR — Female: (10 × kg) + (6.25 × cm) − (5 × age) − 161
TDEE: BMR × activity multiplier
Activity multipliers
The Harris-Benedict and Mifflin-St Jeor activity multipliers used in this calculator are the standard values used across clinical nutrition practice:
- Sedentary (×1.2): desk job, no structured exercise
- Lightly active (×1.375): 1–3 days of light exercise per week
- Moderately active (×1.55): 3–5 days of moderate exercise per week
- Very active (×1.725): 6–7 days of hard training per week
- Athlete (×1.9): very intense daily training or twice-daily training
Male, 30 years, 180 cm, 80 kg, moderately active, steady fat loss goal:
BMR = (10 × 80) + (6.25 × 180) − (5 × 30) + 5 = 800 + 1,125 − 150 + 5 = 1,780 kcal
TDEE = 1,780 × 1.55 = 2,759 kcal
Fat loss target (−500) = 2,259 kcal/day
Goal adjustments
Once you have your TDEE, the calorie adjustments are straightforward:
- Maintain: eat at TDEE
- Steady fat loss (~0.5 kg/week): TDEE minus 500 kcal — the most commonly recommended and sustainable deficit
- Faster fat loss (~0.75 kg/week): TDEE minus 750 kcal — increases muscle-loss risk without close supervision
- Lean gain: TDEE plus 300 kcal — a conservative surplus for muscle building while minimising fat gain
Safety floors
This calculator applies minimum calorie floors to protect against overly aggressive deficits: 1,500 kcal for males and 1,200 kcal for females. Eating below these levels without medical supervision risks lean muscle loss, micronutrient deficiency, and metabolic adaptation. If the calculator shows a caution note, work with a coach or registered dietitian before proceeding.
UAE-specific context: heat, hydration, and Ramadan
The physiological formulas are universal, but applying them in the UAE requires some practical adjustments.
Summer heat and activity level
Dubai temperatures between June and September regularly exceed 40°C, making outdoor exercise impractical. Many residents who train outdoors in cooler months reduce or eliminate outdoor activity in summer — effectively lowering their activity multiplier. If this applies to you, choose "lightly active" or "sedentary" during summer months and adjust upwards in cooler periods. In-home personal training with PTD Fitness is not affected by the season because sessions take place in your air-conditioned home or building gym.
Hydration note
In UAE summer conditions, sweat losses can exceed 1–2 litres per hour during outdoor activity. Dehydration impairs performance and is often mistaken for hunger. Aim for at least 2.5–3 litres of water daily year-round, increasing to 3.5+ litres on active training days. This does not affect your calorie target but significantly affects how you feel at any given intake level.
Ramadan
During Ramadan, your effective eating window changes. TDEE does not change significantly for most people, but the practical strategy does: structure suhoor around slow-digesting protein and complex carbohydrates to extend satiety, and consider placing your main workout 90 minutes before iftar or 2 hours after. Your daily calorie target remains the same — it is compressed into a shorter eating window.
Frequently asked questions
How many calories should I eat to lose weight in Dubai?
To lose fat, eat 300–500 kcal below your TDEE. A 500 kcal daily deficit produces approximately 0.5 kg of fat loss per week. Your TDEE is your BMR multiplied by your activity level. Use the calculator above to get your specific number. Safety floors apply: men should stay above approximately 1,500 kcal/day and women above 1,200 kcal/day without medical supervision.
What is BMR and how is it calculated?
BMR (Basal Metabolic Rate) is the calories your body burns at complete rest — the energy required for breathing, circulation, and cell maintenance. The Mifflin-St Jeor formula: Male BMR = (10 × kg) + (6.25 × cm) − (5 × age) + 5. Female BMR = (10 × kg) + (6.25 × cm) − (5 × age) − 161. This is the most validated equation for most adults and the one used by this calculator.
What is TDEE and how is it different from BMR?
TDEE (Total Daily Energy Expenditure) is your BMR multiplied by an activity multiplier to account for daily movement and exercise. It represents the calories you need to maintain your weight. Most desk workers with 2–4 training sessions per week use a multiplier of 1.375–1.55. BMR is your resting baseline; TDEE is your real-world energy need.
Does Dubai's summer heat affect calorie needs?
Marginally — the body expends slightly more energy on thermoregulation in extreme heat. The larger practical impact is that summer heat tends to reduce outdoor activity, lowering your effective activity multiplier. If you train outdoors in cooler months but move indoors (or reduce exercise) in summer, your TDEE will be lower than your winter estimate. Adjust your activity level selection accordingly. Hydration requirements increase significantly in UAE summer — aim for 3+ litres per day.
How accurate are calorie calculator results?
The Mifflin-St Jeor formula is accurate within approximately 10% for most non-obese adults. Accuracy decreases for very muscular individuals (lean mass raises BMR above the prediction) and in cases of hormonal conditions affecting metabolism. Use the output as a starting point, track weight for 2–4 weeks, and adjust by 100–200 kcal if results do not match expectations. A PTD Fitness coach can combine formula estimates with body composition data for a more precise number.
