Millions of Americans have turned to glucagon-like peptide-1s (commonly referred to as GLP-1s) for weight management. In fact, 1 in 8 U.S. adults has taken a GLP-1 receptor for weight loss or to treat a health condition, according to a recent poll from the Kaiser Family Foundation.\u00a0<\/span><\/p>\n

Mounjaro (tirzepatide)<\/span><\/a> is an injectable medication that is FDA approved for treating Type 2 diabetes. It is a dual agonist for GLP-1 and glucose-dependent insulinotropic polypeptide (GIP) receptors. This combination means it regulates your appetite, controls your blood sugar levels, and may help you achieve your weight-loss goals.\u00a0<\/span><\/p>\n

While you can lose weight without exercise on Mounjaro, medical experts recommend adding physical activity for better and longer-lasting results.\u00a0<\/span><\/p>\n\t\t

Can you lose weight on Mounjaro without exercise?<\/span><\/h2>\n

Exercise may not be possible for everyone on <\/span>Mounjaro<\/span><\/a>. If you have a disability, are new to fitness, or have anxiety around working out, you may be curious if you can still lose weight without hitting the gym.<\/span><\/p>\n

The answer is yes, explains <\/span>Jennifer Wittwer, MD<\/span><\/a>, an endocrinologist based in Cincinnati, Ohio. \u201cTirzepatide leads to a reduction in appetite and food intake, which can lead to weight loss,\u201d she explains. As a GLP-1\/GIP co-agonist, the drug delays gastric emptying and signals to your brain that you are full, which means you consume fewer calories.<\/span><\/p>\n

In one study, 90% of participants <\/span>lost at least 5% of their body weight<\/span><\/a> over a 12-month period, and 57% lost at least 15%. The amount of weight you lose depends on factors that include the dose of medication as well as lifestyle changes, such as keeping a balanced diet and getting enough sleep. In other words, while this medication is remarkably effective, taking steps to improve physical fitness alongside your prescription has major benefits.\u00a0<\/span><\/p>\n

What are the risks of not exercising while on Mounjaro?<\/span><\/h2>\n

If you choose not to exercise while taking Mounjaro, you may still lose weight, but you may also be susceptible to some adverse effects.<\/span><\/p>\n

Failing to maximize weight loss<\/span><\/h3>\n

Exercise has been proven to increase the efficacy of weight-loss injections like Mounjaro and <\/span>Zepbound<\/span><\/a>. One study found that those who exercise while on weight-loss medications see additional benefits, like <\/span>lower abdominal fat percentages<\/span><\/a>, reduced inflammation, and a less severe risk of metabolic conditions like Type 2 diabetes.<\/span><\/p>\n

Having to increase medication<\/span><\/h3>\n

As <\/span>Jennie Stanford, MD<\/span><\/a>, an American Board of Obesity Medicine Diplomate, points out, it\u2019s common for people to develop a tolerance to GLP-1s. That means you may need higher doses of the drug in order to continue to lose weight.<\/span>
\n<\/span><\/p>\n

\u201cExercise is able to attenuate this a bit, helping promote continued weight loss at lower doses,\u201d she says.<\/span> Keeping your doses lower may reduce the side effects of the drug and save you money.<\/span><\/p>\n

Losing muscle mass\u00a0<\/span><\/h3>\n

One potential side effect of Mounjaro and other weight-loss treatments is that while you will likely experience fat loss, you may also lose lean muscle mass.\u00a0<\/span><\/p>\n

In one clinical trial, participants taking tirzepatide were found to have <\/span>lost more lean muscle mass<\/span><\/a> than participants taking a placebo.<\/span><\/p>\n

\u201cWhen we lose weight, and especially when we do so rapidly, we don\u2019t just lose body fat tissue; we also lose lean body mass, including muscle mass,\u201d Dr. Stanford says. \u201cMuscle is incredibly important for metabolism, strength, mobility, and longevity.\u201d<\/span><\/p>\n

Adding resistance training to your weekly routine may help combat this side effect. Studies show that exercise may <\/span>prevent muscle loss<\/span><\/a> in people with weight-loss goals.<\/span><\/p>\n

Losing bone density\u00a0<\/span><\/h3>\n

Weight-bearing exercise is key to maintaining bone density, particularly for people experiencing high-volume weight loss in a short period of time. Dr. Stanford points out that if you are losing a significant amount of weight rapidly without exercising, you may leave yourself vulnerable to fractures.<\/span><\/p>\n

Researchers noted in one medical review that <\/span>moderate weight loss combined with exercise<\/span><\/a> maintains and even increases bone density.<\/span><\/p>\n

Plateauing weight loss<\/span><\/h3>\n

As your body loses weight, it also learns how to become more efficient with the way it operates. \u201cHitting a plateau on tirzepatide therapy is common and expected,\u201d Dr. Wittwer says. Exercise is one way to get past it.<\/span><\/p>\n

There are several ways to overcome this plateau, according to Dr. Stanford and Dr. Wittwer:<\/span><\/p>\n
