BMR, TDEE and exact calorie targets for weight loss, maintenance and muscle gain at age 29.
Using the Mifflin-St Jeor equation with average US height and weight for a man aged 29, the resting metabolic rate (BMR) is approximately 1844 kcal/day. With typical daily activity included, total calorie expenditure (TDEE) ranges from 2212 kcal (sedentary) to 3180 kcal (very active).
| Goal | Daily Calories | Expected Result |
|---|---|---|
| 🔵 Aggressive weight loss | 1785 kcal | ~0.75 kg/week |
| 📉 Weight loss | 2035 kcal | ~0.5 kg/week |
| ✅ Maintenance | 2535 kcal | Weight stable |
| 💪 Lean bulk | 2835 kcal | ~0.25 kg/week |
| 🏋️ Aggressive bulk | 3035 kcal | ~0.5 kg/week |
| Activity Level | Description | Daily Calories |
|---|---|---|
| Sedentary | Desk job, minimal movement | 2212 kcal |
| Lightly active | 1–3 workouts/week | 2535 kcal |
| Moderately active | 3–5 workouts/week | 2858 kcal |
| Very active | Hard training 6–7 days/week | 3180 kcal |
Metabolic rate declines approximately 1–2% per decade after age 30, driven primarily by muscle loss (sarcopenia) rather than any inherent slowdown. At age 29, your BMR of 1844 kcal reflects your current muscle mass, height and hormonal status. The single most effective way to maintain or raise your BMR is resistance training — each kilogram of lean muscle burns roughly 13 kcal/day at rest.
| Age | Estimated BMR (man) | Change vs age 29 |
|---|---|---|
| 19 | 1894 kcal | +50 kcal |
| 24 | 1869 kcal | +25 kcal |
| 29 | 1844 kcal | — |
| 34 | 1819 kcal | -25 kcal |
| 39 | 1794 kcal | -50 kcal |
| Macro | % of Calories | Grams/day | Calories |
|---|---|---|---|
| Protein | 30% | 190 g | 760 kcal |
| Carbohydrates | 40% | 254 g | 1016 kcal |
| Fat | 30% | 84 g | 756 kcal |
At age 29, protein intake is especially important. Aim for at least 71–89 g/day to maintain muscle mass, whether you're in a deficit, at maintenance, or in a surplus.
