Great start! If you still have 50 lbs. to lose I would limit fruit to 1/2 cup berries once a day .
Your wife might be leptin resistant. The keys to resetting LR according to Dr. Jack Kruse are:
A. Eat 50 grams protein w/in 30 min. of waking (7 eggs, 7 oz. Meat)
b. 50 grams carbs per day
c. No Snacking between meals and 5-6 hrs between them
d. 4 hours between dinner and bed
