The Sister Wives personality has been exercising and eating healthy for quite a while, which she documents on her weight loss blog, Strive.
"When I began my own wellness journey 5 years ago, I had reached a point where I knew I had to make a change," she wrote. "I felt like I had too many barriers; physical, mental and otherwise to ever be able to make a real difference in my health. However, once I took the first steps, I found that my life did change, but not in the expected way. I regained a quality of life that I did not know I was missing. I felt good enough to actively participate in my life instead of sitting on the sidelines."
The 48-year-old looks happy and healthy in her recent Instagram photos, and even though she hasn't listed an exact amount of weight that she's lost, she clearly has slimmed down quite a bit.
During her 24 years of "marriage" to her husband Kody Brown, Janelle has been open about struggling with unhealthy eating and her weight.
"I used to be a person that would order out or drive-thru somewhere two or three nights a week," she says on her blog. "And I've come back to really making the base of our meals — meat, or protein, fish, or chicken, whatever it is that I have — and then fruits and vegetables, and then adding potatoes or whatever it is that I have around the same for the children. I've seen our overall health improve, I've seen our grocery budget go down, and I think it's pretty much changed the way that we're eating at home. And that's really led to great success in my fitness journey as well — to improve the way that I'm eating."
