For years, the 37-year-old from Norway tried to lose weight by not eating enough, which would lead her to binge and put the weight back on and then some.
She broke free from that cycle and lost weight in a healthy, sustainable way when when she learned about calories, and started eating more protein and strength training.
Tl;dr. Calorie counting and exercise.
And consistency. You can’t just diet for a few weeks and expect it to go anywhere. You have to keep it up. Lifestyle change for most.
