i have next week through august 22 to do this weight loss program. is there any way i can lose about 25-40 pounds?

To loss the weight i think this option and its work for me:
eat more fruit
drink fresh juice
get detoxification
no junk food
no milk
no yogurt
no soda
drink natural water
sport (like exercise, running, walking, aerobic, swimming)
eat more salad
good sleep
the example eat menu :
Breakfast
Always same: juice presses fresh, as much as desirable, up to 14 ounce fresh succulence as much as desirable, or salad fruit when do you very hungry. When not make difficult, sometimes fun replaced fruit every day that eaten at morning
Lunch
Fresh fruit juice, or carrot juice, 4 - 8 ounce, when does desirable. Salad with fresh vegetable addition desirable and combination sandwich with cucumber or celery.
Dinner
Fresh vegetable cocktail juice, soup cream cauliflower. Potato boat or simple grilled chicken. Garlic flavor string bean. Salad green French.
