Calories In and Calories Out To Manage Weight
The term “calories in” refers to the amount of energy that is obtained from consuming food and beverages. In order to keep your weight at the same level, the number of calories you consume should correspond to the number of calories that your body requires for its everyday activities and functions.
If you consume more calories than your body needs, you will gain weight because your body will store the surplus energy as fat that you consume.
The term “Calories Out” refers to the energy that your body expends in order to carry out fundamental operations such as breathing, digestion, and physical activities. In order to achieve weight loss, it is necessary for your body to burn more calories than it consumes, hence establishing a calorie deficit.
In contrast, if you want to put on weight, you should consume more calories than your body burns, which will result in a surplus of calories than you burn. Getting the right amount of calories in and out of your body is critical to achieving your weight goals.
How Many Calories Should a Woman Eat a Day?
A woman’s age, activity level, and health goals all play a vital role in determining the amount of calories she needs to consume. It is possible to maintain a healthy weight and overall well-being by gaining an understanding of the number of calories that you require on a daily basis.
When it comes to calorie consumption, it is essential to have a personalized approach for women in the United Kingdom, where lifestyle patterns can differ greatly from person to person.
Daily Caloric Needs for Women
A particular number of calories are necessary for the typical woman to consume in order to keep her weight at the same level. In accordance with the National Health Service (NHS), the following are the general guidelines for the amount of calories that women should consume on a daily basis:
Sedentary Women (little to no exercise):
-
- Ages 19-30: Approximately 1,800-2,000 calories per day
- Ages 31-50: Around 1,800 calories per day
- Ages 51+: Roughly 1,600 calories per day
Moderately Active Women (moderate exercise 3-5 days a week):
-
- Ages 19-30: Between 2,000-2,200 calories per day
- Ages 31-50: About 2,000 calories per day
- Ages 51+: Around 1,800 calories per day
Active Women (intense exercise 6-7 days a week):
-
- Ages 19-30: Approximately 2,400 calories per day
- Ages 31-50: Roughly 2,200 calories per day
- Ages 51+: Around 2,000 calories per day
How Many Calories Should a Woman Eat to Lose Weight?
For women aiming to lose weight, the number of calories consumed should be lower than the number of calories burned. A general rule of thumb is to reduce daily intake by 500 calories to achieve a weight loss of about 0.5 kg (1 pound) per week.
However, this should be done cautiously to ensure adequate nutrient intake and avoid negative health impacts.
For example:
- A woman who usually consumes 2,000 calories per day might reduce her intake to 1,500 calories per day to lose weight safely.
It is important to note that extreme calorie restriction can be harmful and counterproductive. Nutritionist Rhiannon Lambert, author of Re-Nourish: A Simple Way to Eat Well, warns against diets that drop below 1,200 calories per day, as they can lead to nutritional deficiencies and metabolic slowdown .
Low-Calorie Diets That Work for a Working Woman
For working women, especially those with busy schedules, finding a diet that fits into their lifestyle is crucial. Here you can check out a low calorie diet plan for men and women to lose weight.
Here are some low-calorie diets that can be effective and practical:
1. The Mediterranean Diet
The Mediterranean diet is renowned for its health benefits and sustainability. It emphasises whole foods such as fruits, vegetables, whole grains, and lean proteins, like fish and poultry. Healthy fats, particularly olive oil, are a staple. This diet is flexible, making it easier to maintain within a busy lifestyle.
2. The 5:2 Diet
The 5:2 diet is a form of intermittent fasting where you eat normally for five days a week and restrict your calorie intake to 500-600 calories on the other two days. This approach can be suitable for working women who find daily calorie counting too time-consuming.
However, it’s essential to choose the fasting days wisely, ensuring they align with less demanding workdays.
3. Meal Prepping
Not a diet per se, but meal prepping can be a game-changer for women with hectic schedules. Preparing meals in advance allows better control over calorie intake and ensures that you always have a healthy, low-calorie option ready.
Focusing on balanced meals with a good mix of macronutrients can help maintain energy levels throughout the day.

Consulting with a registered dietitian or nutritionist can also provide personalized guidance, ensuring that your dietary choices support your health and well-being.
