Like she says, it's not easy and it takes time--by the way, she looks healthy rather than skinny.
It, most importantly, means a permanent change in eating and exercise habits.
Start switching over to a low glycemic index way of eating or basically the way I eat--aim for a good 7 cups of veggies per day(make them leafy veggies like spinach, kale, baby greens, broccoli) I have a small amount of protein with it--maybe 2-3 oz of salmon, sardines, chicken, egg, yogurt, walnuts, almonds
Low Glycemic Index Food Pyramid(Foods to limit are on top working your way down to foods that are almost unlimited)

2 cups of sauteed spinach (saute in small amount of coconut oil or olive oil), add another cup of cut up broccoli and green onion or mushrooms
Add in 1 or 2 whole(organic uncaged is best) eggs
Have with a piece of fruit or a cup of frozen blueberries
or have plain nonfat yogurt with a tbl of walnuts and raspberries with a piece of whole grain bread.
apple and a spoonful of a nut butter or a tbl of nuts
large(3 cups of leafy veggies raw with a light balsamic or lemon dressing) with a 2-3 oz piece of grilled chicken or comparable protein.
pear and a small amount of a lean protein source
large bowl of homemade lentil soup
more veggies &/or a small piece of wholegrain bread or a half baked potato with salsa
