How Weight Loss Injections Help You Remain in a Calorie Deficit

Losing weight can be a challenging journey, and many individuals struggle to achieve their desired results despite their best efforts. One crucial aspect of weight loss is creating a calorie deficit, which means consuming fewer calories than your body needs to maintain its current weight. 

While traditional methods of calorie deficit, such as diet and exercise, are effective for many people, some individuals may find it challenging to sustain a calorie deficit or experience slower progress. In such cases, medical weight loss injections can be a game-changer.

Here at Bodyline, we like to de-mystify the science and debunk the myths about effective weight loss, that’s why we’ve put together this explainer to help you understand the benefits of a calorie deficit for weight loss, and how weight loss injections may be able to help your weight loss journey.

Understanding Calorie Deficit

Before we delve into how weight loss injections can assist in maintaining a calorie deficit, let’s first understand the concept of a calorie deficit. Calories are a unit of measurement used to quantify the energy content in food and beverages. When we consume more calories than our body needs, the excess energy is stored as fat, leading to weight gain. 

On the other hand, when we consume fewer calories than our body requires, it creates an energy imbalance, prompting the body to tap into its fat stores for additional energy. This is known as a calorie deficit and is the key to weight loss.

Challenges in Maintaining a Calorie Deficit

While the concept of a calorie deficit seems straightforward, many people encounter difficulties in maintaining it. Several factors can make it challenging to adhere to a reduced-calorie diet and sustain weight loss. 

These factors include genetic predispositions, metabolic rate variations, hormonal imbalances, and lifestyle factors. Additionally, some individuals may struggle with portion control, mindful eating, and actually sustaining the caloric deficit long enough to see sustainable results.

Katie Illingworth, a nurse practitioner and prescriber at Bodyline explains why calorie deficits, when done wrong, cannot be maintained:

“There is a common misconception that when you’re significantly overweight you should go into a dramatic calorie deficit. Now yes, you will lose weight short term and you’ll think it’s working. But hormonally, you are physiologically causing harm, because your body isn’t designed to do that. It will think it’s gone into starvation mode, or in hibernation. This will mean it starts to store the fat and instead burn your muscle, causing them to feel weak, and tired, and make you more likely to binge.”

The Role of Weight Loss Injections

Weight loss injections, particularly those belonging to the GLP-1 receptor agonist class, have gained significant attention in the field of medical weight loss. GLP-1, or glucagon-like peptide-1, is a hormone that plays a role in regulating blood sugar levels and appetite. Weight loss injections work by mimicking the effects of GLP-1 in the body, promoting feelings of fullness and satiety, regulating blood sugar levels, and reducing appetite.

These injections, administered either once daily or once weekly depending on prescription, are fundamentally designed to assist individuals in maintaining a calorie deficit. You may have heard of them by their brand names, WeGovy (active ingredient semaglutide), Saxenda (liraglutide). 

The latest weight loss injection to hit the market in the UK is a dual hormone agonist containing both GLP-1 and GIP and is Mounjaro (tirzepatide). 

By suppressing appetite, increasing metabolism, and promoting a feeling of fullness, weight loss injections enable individuals to consume fewer calories, ultimately leading to weight loss.


It is important to note that weight loss injections are only available to eligible patients through a prescription. Any sellers offering weight loss injections or “skinny jabs” online without health checks, prescriptions, or ongoing support and side effect monitoring should be avoided as this could be a scam and a danger to health.

If you’re worried about how to know which skinny jabs are legitimate, read this handy guide we put together.


Benefits of Weight Loss Injections

Weight loss injections offer several benefits that contribute to their effectiveness in maintaining a calorie deficit:

1. Appetite Suppression

One of the primary mechanisms of weight loss injections is appetite suppression. By activating GLP-1 or combined GLP-1 and GIP receptors in the body, these injections reduce hunger and food cravings, making it easier to adhere to a reduced-calorie diet. Individuals feel satisfied with smaller portions and are less likely to engage in emotional or binge eating.

2. Regulation of Blood Sugar Levels

GLP-1 and GIP/GIP receptor agonists, such as weight loss injections, help regulate blood sugar levels. By controlling blood sugar spikes and promoting insulin secretion, these injections contribute to overall metabolic health. Stable blood sugar levels reduce cravings for sugary and high-calorie foods, facilitating adherence to a calorie deficit.

3. Support for Lifestyle Changes

Medical weight loss programmes that incorporate weight loss injections should provide comprehensive support for lifestyle changes. Our programmes offer guidance on nutrition, exercise, and behaviour modification, helping individuals adopt healthier habits and sustain weight loss over time. The combination of weight loss injections and a holistic approach increases the chances of long-term success.

Personalised Approach to Weight Loss

It is important to note that weight loss injections are not a one-size-fits-all solution. Each individual’s weight loss journey is unique, and personalized guidance is crucial for optimal results. Working with healthcare professionals who specialize in medical weight loss, such as Bodyline, ensures that individuals receive tailored treatment plans based on their specific needs and goals.
