Background: Obesity is a multiplex metabolism disorder associated with excess fat accumulation. It elevated the menace of cardiovascular system ailment, diabetes mellitus, and other complications. The Present study intended to examine the anti-obesity outcome of ethyl alcohol extract of Malvaviscus arboreus leaves in higher-fatfood-brought-overweight rats. Methods: Leaves of Malvaviscus arboreus were shade-dried, powdered by using a mortar pestle, defatted using petroleum ether laboratory reagent by Soxhlet apparatus, and then extracted the defatted extract with 95% ethanol by Soxhlet apparatus at 70 to 75 ^o C. Albino laboratory rats were alienated into four groups: Control, Standard (Standard drug Orlistat-10 mg/kg High fat diet), Test-1and Test-2. The treatment was given for 42 days, that is 6 weeks, by oral route with the help of oral gavage. The muscle strength and muscle grip were assessed by using Kondziela’s inverted screen maze apparatus, and body weight was recorded regularly. Blood was poised by the retro-orbital perforation method for biochemical investigation for the estimation of serum lipid profile. Results: The test groups, particularly test-2, demonstrated significant improvements. On the 42^nd day, average muscle strength in the test-2 group 4 was (206.60 seconds), close to the standard group 2 was (232.18 seconds), while the test-1 group 3 was (154.32 seconds) and the control group 1 showed only (81.57 seconds). Final body weight was also reduced: control group 1 (248.75 grams), standard group 2 (142.13 grams), test-1 group 3 (171.13 grams), and test-2 group 4 (152.88 grams).
