Sticking to a calorie-controlled diet can be challenging, especially with the diet industry promoting a quick-fix narrative. However, a calorie-controlled diet is an effective way to manage weight and health. The key to success is a long-term, sustainable approach, such as flexible dieting, which gives you control over what and when you eat and focuses on tracking calories and macronutrients. This method allows for the occasional indulgence, which makes it a realistic and flexible approach. To get started, it's important to calculate your total daily energy expenditure (TDEE) and determine your calorie needs, which depend on factors like age, sex, height, weight, and exercise habits. From there, you can create a calorie deficit by reducing your daily intake by 300-500 calories, which will lead to weight loss. It's also beneficial to focus on whole foods, increase your water intake, and be mindful of portion sizes. Remember, slow and consistent weight loss is more sustainable, and it's essential to consult a healthcare professional for guidance and support.

What You'll Learn
Calculate your TDEE (Total Daily Energy Expenditure)
To stick to a calorie-controlled diet, it is important to calculate your Total Daily Energy Expenditure (TDEE). This is an estimate of how many calories you burn per day, taking into account your exercise levels. TDEE is calculated by first figuring out your Basal Metabolic Rate (BMR) and then multiplying that value by an activity multiplier.
Your BMR is a measure of how many calories your body burns at rest, or the minimum energy required to maintain vital organs. It is calculated based on physical characteristics such as age, gender, height, and weight. There are several equations commonly used to estimate BMR, including the Mifflin St-Jeor Equation, Harris-Benedict equation, and Katch-McArdle Formula. These formulas are quite similar, but the Katch-McArdle Formula takes metabolic activity into account, which can be useful for those with higher metabolic rates.
Once you have calculated your BMR, you can adjust this number upwards to account for the calories burned during daily activities. This will give you your TDEE, which is a useful tool for understanding your calorie needs and how to adjust your diet and exercise habits to meet your goals.
It is important to note that creating too large of a calorie deficit can be dangerous and is not recommended. A small deficit is often more sustainable and allows for muscle growth alongside fat loss. Additionally, your calorie needs will vary depending on the day and your activity levels, so it is important to be flexible and adjust your intake accordingly.

Avoid highly processed foods
A calorie-controlled diet is a great way to jumpstart weight loss and control food intake. However, sticking to such a diet can be challenging, and one of the biggest obstacles is the temptation to consume highly processed foods. These foods are designed to be convenient, appealing, and heavily marketed, making them hard to resist. Here are some reasons why it is essential to avoid highly processed foods and strategies to help you make healthier choices:
Health Risks of Highly Processed Foods:
Research has linked diets high in ultra-processed foods to an increased risk of health issues, including obesity, type 2 diabetes, and heart disease. These foods tend to be low in fiber and high in calories, saturated fat, salt, added sugar, and other additives. While not all processed foods are unhealthy, many ultra-processed options fall into this category.
Impact on Overall Nutrition:
Highly processed foods often contain high levels of saturated fat, salt, and sugar. When these foods dominate your diet, there is less room for more nutritious options. Whole foods, such as fruits, vegetables, whole grains, and lean proteins, offer a wider range of essential nutrients, including vitamins, minerals, and fiber.
The Processing Itself Matters:
The extent of processing that these foods undergo may be a critical factor in their negative impact on health. Ultra-processed foods often have water removed to extend their shelf life, resulting in more calories per bite. Additionally, the combinations of fat, salt, and sugar in these foods may be formulated to make them irresistible, leading to overconsumption.
Strategies to Avoid Highly Processed Foods:
- Cook with Whole Foods: Cooking meals from scratch using whole foods gives you greater control over the ingredients and nutritional content. You can ensure that your meals are balanced and contain the essential nutrients your body needs.
- Limit Prepackaged Meals: Prepackaged meals often contain higher levels of fat, sugar, and salt. Opt for homemade meals or, if necessary, choose prepackaged options with minimal processing and added ingredients.
- Stick to Traditional Cheeses: Instead of highly processed cheese slices, spreads, or shredded cheeses, buy a block of traditional cheese like Cheddar and slice it yourself. This option is generally cheaper and healthier.
- Read Food Labels: When shopping for groceries, take the time to read food labels. Look beyond the marketing claims and check the nutrition information, including calorie, saturated fat, salt, and sugar content. Some labels use colour-coding to help you quickly identify high or low levels of these nutrients.
- Focus on Whole, Unprocessed Foods: Prioritize including more whole, unprocessed, or minimally processed foods in your diet. This includes fruits, vegetables, milk, fish, pulses, eggs, nuts, and seeds in their natural state, with no added ingredients.
- Increase Your Awareness: Understand the definition of ultra-processed foods and how they can negatively impact your health. This awareness can help you make more informed choices when shopping for groceries or ordering meals.

Exercise to burn more calories
Exercise is a great way to burn more calories and create a calorie deficit, which is essential for weight loss. Combining a healthy diet with physical activity will help you achieve optimal results for calorie expenditure.
Running
Running is an excellent exercise for burning calories, with approximately 500 to 1000 calories burned per hour. The number of calories burned depends on various factors, including weight, pace, speed, and endurance. Running is effective because it increases heart rate and uses several muscle groups, leading to increased energy expenditure. However, it may not be suitable for everyone, especially those with osteoporosis or heart and lung conditions.
High-Intensity Interval Training (HIIT)
HIIT is a form of anaerobic training that involves short bursts of intense activity followed by brief rest periods. This type of training keeps the body's excess post-exercise oxygen consumption (EPOC) and calorie burn elevated for hours after the workout. HIIT can be done with or without equipment and focuses on intensity rather than the need for a gym or specific tools.
Strength Training and Weightlifting
Strength training and weightlifting are important for building muscle mass and increasing basal metabolic rate (BMR), which is the rate at which you burn calories at rest. These exercises also boost EPOC, leading to increased calorie burn even after the workout is completed. While weightlifting may burn fewer calories during the activity itself compared to running, it has a lasting impact on calorie expenditure and is beneficial for overall fitness.
Swimming and Hiking
Swimming is a great option for those who prefer low-impact exercises, as it provides a high-calorie burn without the same stress on the body as running. Hiking is another enjoyable activity that can burn calories effectively while offering a change of scenery and the benefits of being in nature.
Consistency and Nutrition
Consistency is key when it comes to achieving your calorie-burning goals. Regular exercise, combined with a nutritious eating plan, will maximize your level of calorie burn. Focus on nutrient-rich foods such as fruits, vegetables, lean proteins, and whole grains to fuel your workouts effectively. Additionally, ensure you stay hydrated with water, as thirst can sometimes be confused with hunger, leading to unnecessary snacking.

Drink water to suppress hunger
Drinking water is an effective way to suppress hunger and control your appetite, especially if you drink it before a meal. Research has shown that drinking two cups of water before eating can help control your appetite and prevent overeating. This is because the water takes up space in your stomach, tricking it into sending "I'm full" signals to your brain.
Drinking water before a meal will reduce your hunger and lead to a reduced calorie intake. This is because water is calorie-free, and drinking it before a meal can also slightly increase your metabolism. If you drink sugary, high-calorie beverages, swapping them out for water will help curb your appetite and contribute to weight loss.
When you feel hungry, your first impulse may be to find food. However, your brain may be mistaking thirst for hunger. Thirst is often triggered by mild dehydration, so drinking water may be the answer.
Drinking water can also promote a feeling of satiation because it passes through the system quickly, stretching the stomach. This is why it is recommended to drink water before a meal, as it can help you feel fuller faster, and prevent overeating.
It is important to stay hydrated, and drinking water is a good way to do this. There are few, if any, downsides to drinking more water.

Avoid restrictive diets
While it may be tempting to restrict your calories to the extreme to see faster results, this can be detrimental to your health. Firstly, it is important to remember that weight loss is a complex process that involves many factors, not just "calories in, calories out". Biological factors, such as metabolic rates, gut bacteria, and hormonal levels, can all affect weight loss and vary from person to person. Restricting calories too much can lead to fatigue, nutrient deficiencies, and even negatively impact fertility.
Additionally, very-low-calorie diets (VLCDs) are not recommended for routine weight management and should only be done under medical supervision. While they may lead to greater weight loss in the short term, they are not sustainable and may not be successful in maintaining weight loss over a long duration. Instead of focusing on severe calorie restriction, opt for diets that emphasize diet quality and encourage sustainable lifestyle changes. For example, limiting highly processed foods and added sugars can help with weight loss and improve your overall health.
It is also important to note that creating too much of a calorie deficit can be harmful. Your body needs a certain number of calories to sustain its basal metabolic rate (BMR). Eating fewer calories than are required to sustain your BMR can cause your metabolism to slow down, and this lower metabolism can persist even after you stop the diet. This may explain why many people regain weight after stopping a calorie-restricted diet.
Finally, severely restrictive diets can lead to disordered eating and negative feelings, potentially leading to problematic eating habits and even eating disorders. Calorie-restricted diets may also not provide sufficient amounts of essential nutrients like iron, folate, vitamin B12, calcium, and protein, leading to health issues. Therefore, it is crucial to avoid overly restrictive diets and focus on creating a sustainable calorie deficit that takes into account your individual needs and health.

Frequently asked questions
Calorie restriction is a consistent pattern of reducing average daily caloric intake, without malnutrition or deprivation of essential nutrients.
Here are some tips to cut calories:
- Eat low-calorie foods that are rich in fibre and keep you full, like fruits and vegetables.
- Choose whole fruits over fruit juice.
- Drink tea and coffee without sugar.
- Steam or grill vegetables instead of cooking them in butter or oil.
- Check food labels and serving sizes to be aware of how many calories you're consuming.
Intermittent fasting is a weight loss method that cycles between periods of fasting and eating. It is a popular way to cut calories.
There are many ways to do intermittent fasting. Some examples are:
- Time-restricted eating: Eating only between certain hours of the day, for example, between 8 am and 4 pm.
- 5:2 system: This could mean eating normally for five days of the week and restricting calories for two non-consecutive days.
- Alternate-day fasting: This could mean fasting every other day or eating only every other day.
Calorie-controlled diets that are too restrictive or extreme can be unsafe and are not recommended for long-term weight loss. Rapid weight loss can also be unsafe and may not be sustainable. It is always best to consult a healthcare provider before starting a new diet.
