The 34-year-old Canadian singer shed the weight over three months after making a conscious decision to drastically change her eating habits.
She said: "I used to get out of bed in the morning and things were aching, and I just thought, this is what happens when you get into your 30s.
"But now I jump out of bed and have so much energy. I feel very alive. I have no more aches and pains, and my allergies are gone, too."
Alanis' food inspiration came from a book on healthy eating by Dr. Joel Fuhrman.
She continued: "I saw this book, 'Eat to Live', and thought, that's exactly what I want to do. I wasn't interested in some fad diet that was unsustainable. I don't believe in diets - I think they're short-term and a bit of an emotional roller-coaster."
Alanis is convinced she started overeating to compensate for all the years she concentrated on her career instead of having fun as a young woman.
She added to America's OK! magazine: "All the restrictions and limitations I'd placed upon myself for many years were let loose. I think it was a rite of passage for me. At 21, I was touring, so I didn't experience the footloose and fancy-free passage that most people do in their teens and early 20s.
"My whole life I've been overly responsible. So I was fantastically indulgent for a good nine months. I knew it would be a temporary thing, and it was fun. There was a sexiness to my curvier self that I loved."
