Why Is a Calorie Deficit Important for Weight Loss?

If you’ve been researching the best way to lose weight, you’re sure to have heard the term ‘calorie deficit’ thrown around. Counting calories as part of an effort to lose weight is nothing new, but why is there a sudden fixation on calorie deficits in the weight loss world, and what does it do for weight loss?

Here at Bodyline, we aim to help explain the world of weight loss to make it more accessible and easier to understand, without making unfounded promises of miracle cures or overnight weight loss. That’s why we’ll be explaining why calorie deficits are oh so important for sustained and effective weight loss, and how medical weight loss treatments may be able to pull you out of the toxic cycle of fad diets and binging.

What Are Calories?

Before we delve into the importance of a calorie deficit for weight loss, let’s first understand what calories are. Calories are a unit of measurement used to quantify the energy content in food and beverages.

When we consume food, our bodies break down the nutrients and convert them into energy to fuel various bodily functions. When we eat too many calories, more than our body needs to fuel its functions, we store excess energy as fat, leading to weight gain; this is called a calorie surplus. Ideally, if we are at a healthy weight and want to remain that way, we should be consuming a number of calories equal to the number of calories we burn, which is called calorie maintenance.

When we want to begin to burn the energy stored in the body as fat, this is where calorie deficits come in.

How Do Calorie Deficits Work?

A calorie deficit occurs when you consume fewer calories than your body needs to maintain its current weight. This creates an energy imbalance, prompting your body to tap into its fat stores for additional energy. In other words, when you consistently maintain a calorie deficit, your body starts burning stored fat for fuel, leading to weight loss.

You’ll be surprised to know that pretty much all fad diets, diet plans, and weight loss advice are forms of calorie deficits as it is the only way to effectively lose fat. The issue in weight loss stems from how sustainable the calorie deficit route you take is.

If you’re skipping meals, restricting yourself to minimal foods, or attempting an extreme fad diet, it is likely you will lose a bit of weight, burn out from the restrictive lifestyle, and end up binging and piling the weight back on. And so, the cycle continues, as we try other fad diets that promise to transform our bodies and lead to miraculous weight loss. Polls have shown that brits are likely to try around 126 fad diets across the course of our lives, going to show how ineffective and unsustainable they are for weight loss.

That’s why so many diet and weight loss attempts fail, which begs the question, how do you actually stay in a calorie deficit and lose weight?

How Do You Remain in a Calorie Deficit?

To achieve a calorie deficit, you need to carefully monitor your calorie intake and ensure it is lower than your body’s energy expenditure.

Katie Illingsworth, a member of Bodyline’s team of registered nurse prescribers and a trained nutritional therapist has some tips.

““There is a common misconception that when you’re significantly overweight, if you go into a dramatic calorie deficit, you will lose more weight. Now, you will lose weight within the first two months, and you’ll think it’s working. However, you are impacting your hormones because your body isn’t designed to do that. It thinks it’s gone into starvation mode. It’s thinking you are in hibernation, so after a period of time you stop losing weight and start to store the fat, while burning your muscle. That leaves us not losing weight and feeling weak and tired, unable to continue.

“What you have to do is work out something called your TDEE, or ‘Total Daily Energy Expenditure.’ You can find a calculator online; the handiest one is fatcalc.com. The total TDEE, and therefore your calorie deficit, is based on your height, weight, age, gender, and activity levels. For example, mine might be 2,500 calories. If I want to lose a pound a week, I will have to take off 500 calories, or if I wanted to lose two pounds a week, I’d take off 1,000 calories. But when you say to someone, you’re in a calorie deficit of 2,000, they might assume that’s not calorie deficit. Well, it is for my body type.”

Once you have worked out your calorie deficit using the online calendar, you must only eat food and drinks within that calorie budget. The more you exercise, the more of a deficit you may create.

What If Calorie Deficits Don’t Work for Me?

While calorie deficits are a widely recognised method for weight loss, individual responses may vary. Some people may find it challenging to sustain a calorie deficit or experience slower progress. If traditional methods of calorie deficit aren’t working for you, it’s essential to explore alternative approaches that can help you reach your weight loss goals.

You may have heard about the medical weight loss injections and oral treatments sweeping the world right now due to their ‘game-changing’ results. Treatments including GLP-1 receptor agonists and glucose-dependent insulinotropic polypeptide (GIP) work by helping you to remain in a calorie deficit, thus burning your fat stores and leading to weight loss.

GLP-1 and GIP injectable therapies mimic the effects of the hormone glucagon-like peptide-1, which is naturally produced in the intestines upon finishing a meal, signalling to the brain that the meal is finished and promoting the feeling of fullness. GLP-1 plays a role in regulating blood sugar levels and appetite. When mimicked with the help of weight loss injections, users consume less food, therefore less calories, allowing them to lose weight much easier.

Clinical trials have shown that weight loss injections can lead to significant and sustainable weight loss. For example, in trials of semaglutide known as WeGovy, individuals lost an average of 15% of their overall body weight over a 68-week period.  Mounjaro is clinicall proven to support weight loss of 20-25%.

These injections, administered once daily or once weekly depending on the active ingredient, are known by their brand names: WeGovy, Saxenda, and more recently Mounjaro. Bodyline also offers incredibly effective oral treatments, Phentermine and Diethylpropion that are also effective in the maintenance of a calorie deficit.

If you think you might benefit from medical weight loss treatments like those listed above, Bodyline’s medical weight loss programmes could be perfect for you.

These medications can help suppress appetite, increase metabolism, and promote fullness, all of which contribute to maintaining a calorie deficit.

Obesity has become a significant concern in the workplace, impacting both employees and employers. Over a quarter of UK adults are currently living with obesity, and numbers are rising across the world. Routines, work environments, and job demands can influence eating habits, activity levels, and overall weight health. As a result, it is crucial for employers to address obesity and support their workforce's weight management journey.
When it comes to weight loss injections, it's hard to ignore the buzz surrounding these treatments and their potential to help individuals achieve their weight loss goals. However, with the rise in popularity of these injections, it's important to be aware of the risks associated with unregulated sources and fake products. Too often we see the scary headlines of near-death experiences, serious illness, and adverse reactions from counterfeit “skinny jabs” and weight loss injections. The online black market of injectable appetite suppressing medications promises cheap prices for quick fixes, but that is not how weight loss works.
As obesity levels are rising across the world, clinicians and medical professionals are emphasizing the fact that our weight can have a significant effect on our wellbeing, both physically and mentally. That’s why it’s absolutely vital that we boost public health knowledge regarding obesity and weight health, so that we know when our weight is becoming a problem, and how we can fix it. That’s where handy tools like the BMI comes in, so we can identify whether or not our weight is healthy or unhealthy, and whether we need to address this to improve our overall weight health. Here at Bodyline, we’d like to expand on what the BMI is, how it is used to identify obesity, and how we can help to lower the BMI if it is getting too high.
