How Effective Is Ozempic for Weight Loss? A Nutritionist’s Perspective

With the rise of social media, there is a lot of information about Ozempic and its role in weight loss. I often hear many questions about Ozempic as a nutritionist, including:

• How well does Ozempic work?
• If I’ve tried losing weight through diet and exercise, can Ozempic help me?
• Will I regain my weight after going off of Ozempic?

These questions are all very important. Weight management is generally not as simple as eating less and moving more. There are many things that play a role in your body weight, including genetics, hormones, sleep cycles, level of stress, any underlying medical conditions, and lifestyle behaviors.

Ozempic has changed the way we look at treating obesity; however, understanding its limitations and benefits is key. Ozempic helps some people achieve their goal of losing weight, but it is not the only solution you should be using.

In this article, I will review how Ozempic works, how effective it is for weight loss based on current research, and how important nutrition is for reaching long-term weight loss goals.

What Is Ozempic?

The medication known as semaglutide is the brand name Ozempic. Semaglutide was originally developed to assist individuals with Type 2 diabetes with their blood sugar control.

The class of drugs that semaglutide belongs to is called GLP-1 receptor agonists.

GLP-1 (Glucagon-Like Peptide-1) is a naturally produced hormone in the gastrointestinal tract that is secreted after eating, and there are many important functions of GLP-1, including:

• Appetite Regulation
• Insulin Secretion
• Blood Glucose Regulation
• Digestive Processes
• Sense of Fullness

Researchers quickly found that patients taking semaglutide were not only having better blood sugar control, but they were also losing significant amounts of weight. As a result, researchers began to study the effects semaglutide would have on managing obesity.

In the present time, semaglutide-based products are now widely utilized in an overall weight management plan under medical supervision.

How Does Ozempic Support Weight Loss?

Ozempic doesn’t “melt” fat—and there are many factors to how Ozempic accomplishes this goal.

Ozempic does help people manage their weight through two main mechanisms: 

1. Modifying Hunger Behaviors: The majority of people taking Ozempic report a decrease in hunger. This can be beneficial if you constantly have difficulty managing your urges to eat because you have a history of overeating and/or are generally unable to control those urges. Therefore, successful “dieting” is often only possible when your hunger levels are regulated; if your hunger is not properly managed, making good food choices becomes much more difficult.
2. Increasing Satiety: Ozempic will slow down the speed at which food is processed in the stomach. This leads to satiety being reached sooner and will require people to snack less and use smaller portion sizes after consuming the food.
3. Better Management of Blood Sugar: Fluctuations or lack of stability in blood sugar levels can lead to cravings and low energy.

When blood sugar is more stabilized, it should also help reduce the above challenges associated with poor blood sugar management. Therefore, it should be easier to continue to be consistent in the way you eat.

What Does the Research Say?

Ozempic has become increasingly popular for many reasons, one of which is the extensive research supporting semaglutide. 

In the STEP-1 clinical trial, adults with diabetes who were given semaglutide in addition to making changes to their eating habits lost weight – about 14.9% of their body weight (about 15 kg for a 100 kg person) – over a total of 68 weeks. 

The research also showed positive improvements in some health measures for people using semaglutide: 

• waist circumference; 
• blood sugar control; 
• blood pressure; 
• cholesterol levels; and 
• general cardiometabolic health. 

As a dietician, I’m particularly excited about these outcomes because I believe that successful weight control means positive long-term health outcomes; it does not just mean a good number on the scale.

How Much Weight Can You Expect to Lose?

Most of the time, clients will ask this question. The truth is that people get different results for many reasons.

For instance, there are many factors that affect a person’s weight loss success, including:

• Starting Body weight
• Past medical history
• Food and fluid intake
• Exercise level
• Quality of sleep
• Stress levels
• Follow-through with treatment

While some clients might lose a significant amount of weight, others might only lose a little.

The thing I remind clients of all the time is how much more useful it is to have stable progress than to have rapid progress.

A realistic and healthy weight loss plan will help develop those types of habits and behaviors that will remain consistent throughout your life.

The Side Effects You Should Know About

Ozempic will lead to adverse effects, the incidence of which varies among the patient population. Cases of the following include:

• Nausea 
• Vomiting
• Constipation 
• Diarrhea 
• Bloating 
• Stomach pain. 

Oftentimes, these symptoms will go away over time as the body gets used to the medication. 

However, I will often notice that once people make significant calorie reductions and/or skip meals, the side effects can be even worse. This is where nutrition education and guidance are extremely important to make good food choices and to properly adjust their meals, resulting in less severity of the side effects and maintaining ample nutrition in their diet during treatment.

A Concern We Discuss Frequently: Muscle Loss

Rapid weight loss could reduce muscle mass significantly. When your weight goes down, not all of it comes from fat. Weight can also decrease from: 

• Muscle tissue loss 
• Loss of water weight (dehydrated) 
• Depletion of glycogen stores 

These differences in weight could cause problems with: 

Your metabolism (metabolic health) 

Your physical strength 

Your ability to use insulin properly (insulin sensitivity) 

Your functional ability as you age 

Therefore, we recommend that anyone who is losing weight, through medication or through a lifestyle change, should eat enough protein and do some type of strength training. 

When you are working to lose weight, you should work toward improving your body composition and health in general.

What Happens If You Stop Taking Ozempic?

Many individuals who take medications to lose weight worry about regaining lost weight as well once they have stopped using the medication. Although some may regain some of the lost weight once they stop using the medication, that does not mean the medication was a failure. This highlights a reality of weight management – if long-term eating habits and activity levels have not been modified, then the ability to maintain weight will be very difficult. The people whom we have observed to have the best long-term weight maintenance have successfully utilized the time they were on the medication to develop lasting healthy habits, which will continue to support their maintenance after they stop taking the medication.

Why Nutrition Still Matters While Taking Ozempic

There are common misconceptions about the relationship between Ozempic and appetite. Many believe that if the appetite decreases, then there will be less importance on overall nutrition. In actuality, I would argue that it is the other way around. The lower the amount of food consumed during a given time period (or after using Ozempic), the more important that food becomes, especially with the following:

• Inadequate amounts of protein,
• Vitamin and mineral deficiencies,
• Fatigue,
• Poor recovery,
• Loss of lean muscle mass.

The best way to ensure that you’re meeting your nutritional needs is to develop a well-structured nutrition plan to meet those needs when your food consumption has decreased substantially.

Some of the key areas I tend to discuss/implement with my clients are as follows:

Protein – protein is essential for muscle maintenance, feelings of satiety, recovery from exercise, and metabolic health.

Fibre – fibre is necessary for digestive health, blood sugar control, and feelings of fullness (satiation).

Hydration – due to decreased food intake and/or GI side effects, the chance of being dehydrated is increased.

Physical activity – strength training continues to be one of the best methods to maintain lean muscle while losing weight.
