American rapper and songwriter Missy Elliott’s appearance at the 65th Annual Grammy Awards on Sunday, February 5, left fans in a daze. They regarded the hip-hop star’s dramatic weight loss as her aging backward.Although the rapper graced the stage in her signature baggy attire, viewers could still figure out her transformation.

Symptoms include weight loss, hair loss, dizzy spells, lumps in the throat, irregular heartbeat, muscle weakness, fatigue, and mood swings.Missy Elliott's weight loss journeyElliott's illness does not have an absolute or permanent cure, but it can be controlled with medication, exercise, and a change in diet. The Work It rapper changed her lifestyle in 2008 after she was diagnosed with the illness.

She managed to control her condition through exercise and diet only.Previously, Elliott weighed around 89 kg and to keep her illness in check, she knew she needed to lose some weight. She started her routine in 2011, and in 2018, she shared her diet secrets when she unveiled a brand new image of herself, appearing healthier and lighter.Missy Elliott (now) (Image via Facebook/Missy Elliott)Elliott shared that she restricted her consumption of all calorie-dense products for four months straight.
