Mounjaro (tirzepatide) is generally considered more effective for weight loss than Ozempic (semaglutide) due to its dual-action mechanism (targeting GIP and GLP-1 receptors) compared to Ozempic's single GLP-1 action, leading to greater average weight loss (up to 20%+ vs. 10-15%), but the "better" choice depends on individual response, cost, insurance, and tolerability, as both have similar side effects like nausea, and Ozempic (semaglutide) is available as Wegovy for weight loss in some regions.
The weight-loss injection Mounjaro (tirzepatide) leads to greater weight loss than Wegovy (semaglutide), according to UK news outlets reporting on a new study. The research found Mounjaro reduced body weight in people with obesity by just over 20 per cent, whereas Wegovy cut it by nearly 14 per cent.
Yes, switching from Ozempic to Mounjaro is an option if you and your healthcare provider decide it's the right move. This decision largely depends on why you're using Ozempic and the effectiveness of your current treatment plan. Other factors, like side effects and costs, should also be considered.
The "best" weight loss injection depends on individual needs, but Mounjaro (tirzepatide) is often considered the most effective for significant weight loss (around 20-22.5%), followed by Wegovy (semaglutide), both working weekly. Mounjaro targets two hormones (GLP-1 and GIP) while Wegovy targets one (GLP-1), leading to stronger results for some, but both require diet and exercise, and individual suitability with a doctor is key.
Kelly Clarkson lost significant weight through a combination of doctor-guided medication, a protein-focused diet (like the Plant Paradox plan), cutting processed foods, and increased physical activity, primarily daily walking in New York City, motivated by health concerns like being pre-diabetic. She emphasizes listening to her doctor and focusing on consistent, healthy lifestyle changes rather than crash dieting, incorporating methods like infrared saunas for detoxification.
Mounjaro may be 3 times more effective than Ozempic, study finds
Which is cheaper: Mounjaro or Ozempic?
Mounjaro is more expensive than Ozempic. In early 2024, the cost of Ozempic without insurance started at around $935 a month in the U.S. Mounjaro's list price was $1,069 per fill, according to the Eli Lilly website. Some reports say the drug can cost as much as $1,267.
Most people taking Ozempic see big changes within the first 2 to 6 months depending on the dosage adjustments. Patients can expect 2 to 6 lb per month weight loss and a total of 10 to 15% or body weight loss for the period of 6 to 12 months.
Why are people switching from Ozempic to Mounjaro?
Mounjaro® often shows faster initial weight loss compared to Ozempic®, as well as outperforming Ozempic® in patient total weight loss. This is thought to be largely thanks to its dual-hormone formulation.
While each weight loss treatment may require you to eat different foods for the best results, if you're using Mounjaro, you'll need to avoid sugary foods, fried foods, refined carbohydrates, fizzy drinks, and alcohol.
Which has worse side effects, Ozempic or Mounjaro?
Both medications have similar gastrointestinal side effects, but their frequencies differ slightly. Mounjaro tends to cause more diarrhea (12-17% vs 8.5-8.8%), while Ozempic users report more nausea (16-20% vs 12-18%). Vomiting rates are similar at about 5% for both medications.
Will Ozempic or Wegovy reduce belly fat? The answer appears to be yes. That Novo Nordisk-funded study of almost 2,000 overweight or obese adults without diabetes also found their visceral fat — the type that accumulates in the belly — was reduced from baseline with semaglutide, along with their total fat mass.
Ozempic and Mounjaro have shown promising results in reducing cardiovascular risk, particularly in individuals with type 2 diabetes and established cardiovascular disease. While Mounjaro is not yet FDA-approved for this indication, emerging evidence suggests similar cardiovascular benefits.
Most people lose around 1kg or 1.1% of their body weight in their first month on Ozempic, according to data from randomised controlled trials1. After two months, this increases to around 2kg or 2.2% of body weight.
'Ozempic hands' is an informal term describing visible changes in hand appearance—such as more prominent veins, tendons, and bones—reported by some individuals taking semaglutide (Ozempic or Wegovy).
Why is Mounjaro better than Ozempic for weight loss?
Mounjaro®: As a dual agonist, Mounjaro® activates both GLP-1 and GIP, providing enhanced weight loss benefits compared to medications that target only GLP-1. Ozempic®: Ozempic® works solely on GLP-1, which is effective but may not provide the same level of weight loss as Mounjaro®.
The 3-3-3 rule for weight loss is a simple habit-based framework focusing on 3 balanced meals, with 3 hours between meals, and 3 hours of movement per week, often paired with drinking water (like 3 bottles by 3 PM) and avoiding things like sugary drinks to promote sustainable fat loss by regulating appetite, boosting metabolism, and building consistency without complex calorie counting.
Kelly Clarkson admitted she used a weight loss drug to transform her body. While chatting with Whoopi Goldberg, about her recent transformation with the help of the Type 2 diabetes weight loss drug Mounjaro, Clarkson admitted she's dabbled with one of her own.
It was a revision to a gastric sleeve — the same type of surgery her mother Sharon Osbourne had once tried — that created a bigger shift. Around 2018, Kelly quietly underwent the procedure. Over the next two years, she would lose about 85 pounds, dropping from the low 200s to around 125 lbs.
