‘Exercise-In-A-Pill’ Mimics Effects Of Working Out Without Lifting A Muscle

Sweat it out or skip the gym? Researchers have created a pill that mimics some of the effects of exercise. The compound, called SLU-PP-332, holds promise for individuals struggling to exercise due to health limitations or age.

With the new drug, you won’t have to lift a finger. Well, except to pop it in your mouth. SLU-PP-332 works by tricking the body’s muscles into thinking they’re undergoing an intense workout. This triggers metabolic pathways usually activated by exercise, leading to increased calorie burning and fat breakdown.

Don’t count on ditching the treadmill, however—SLU-PP-332 isn’t meant to be a magic bullet for couch potatoes. Exercise offers a wide range of benefits beyond weight management, including improved mental health, stronger bones, and a reduced risk of chronic diseases. Researchers emphasize that the pill is intended as a substitute for those who genuinely cannot exercise.

“We cannot replace exercise; exercise is important on all levels,” stresses Bahaa Elgendy, a professor at Washington University School of Medicine in St Louis and the project’s principal investigator. “If I can exercise, I should go ahead and get the physical activity. But there are so many cases in which a substitute is needed.”

Ripped Rodents

In studies, mice given the drug lost a significant amount of body weight compared to a control group without changing their diet or activity level.

“This compound is basically telling skeletal muscle to make the same changes you see during endurance training,” notes Thomas Burris, a professor of pharmacy at the University of Florida. “When you treat mice with the drug, you can see that their whole body metabolism turns to using fatty acids, which is very similar to what people use when they are fasting or exercising. And the animals start losing weight.” 

So how does this work? SLU-PP-332 targets estrogen-related receptors (ERRs) in muscle cells. These receptors play a key role in the metabolic changes triggered by exercise. By activating ERRs, the drug mimics exercise’s influence on muscle growth and metabolism, potentially offering a solution for muscle loss associated with aging or illness.

Crunching More Than Just Abs

While still in its early stages and tested only on rodents, SLU-PP-332 represents a significant step forward. Researchers are currently refining the compound and related drugs to ensure safety and effectiveness as a pharmacological alternative for humans who genuinely can’t exercise.

Beyond weight management, this research, published in the Journal of Pharmacology and Experimental Therapeutics, suggests that the medication has benefits against obesity, heart failure, and age-related declines in kidney function. Additionally, ERR activity is linked to processes that combat neurodegeneration, making it a potential treatment for Alzheimer’s disease and other neurological conditions. While SLU-PP-332 itself cannot reach the brain, newer compounds based on this research might be able to.

So, although you still have to run the extra mile to keep fit, there’s at least a new muscle in the fight against some of humanity’s most pressing health challenges.
