Introduction
As a 13-year-old girl, you’re going through a lot of physical and emotional changes. Your body is growing and developing, and you need to make sure you’re getting the right nutrients to support your health. Calories are units of energy, and they are essential for fueling your body’s activities. But how many calories should a 13 year old girl eat?
The Answer: It Depends
The number of calories you need each day depends on a number of factors, including your age, weight, height, and activity level. However, the general recommendation for 13-year-old girls is to consume between 1,600 and 2,200 calories per day.
How to Determine Your Calorie Needs
To determine your specific calorie needs, you can use the following formula:
BMR (Basal Metabolic Rate) = 655 + (9.6 × body weight in kg) + (1.8 × body height in cm) – (4.7 × age in years)
Once you have calculated your BMR, you can use the following multipliers to adjust for your activity level:
- Sedentary (little to no exercise): BMR x 1.2
- Lightly active (light exercise most days of the week): BMR x 1.375
- Moderately active (moderate exercise most days of the week): BMR x 1.55
- Very active (hard exercise most days of the week): BMR x 1.725
- Extra active (very hard exercise most days of the week): BMR x 1.9
For example, if you are a 13-year-old girl who weighs 50 kg, is 160 cm tall, and is moderately active, your calorie needs would be:
- BMR = 655 + (9.6 × 50) + (1.8 × 160) – (4.7 × 13) = 1,369 calories
- Calorie needs = 1,369 calories x 1.55 = 2,115 calories
What to Eat
Once you know how many calories you need each day, you can start to make healthy choices about what to eat. Focus on eating whole, unprocessed foods, such as:
- Fruits and vegetables
- Whole grains
- Lean protein
- Low-fat dairy
What to Avoid
Limit your intake of processed foods, sugary drinks, and unhealthy fats. These foods are high in calories and low in nutrients, and they can contribute to weight gain and other health problems.
Common Mistakes to Avoid
When trying to lose weight, it’s important to avoid making the following mistakes:
- Skipping meals: Skipping meals can lead to overeating later in the day.
- Eating too quickly: Eating too quickly can make it difficult to feel full, which can lead to overeating.
- Eating out too often: Eating out can be more expensive and less healthy than eating at home.
- Not getting enough sleep: When you’re sleep-deprived, your body produces more of the hormone ghrelin, which makes you feel hungry.
