Acai is very a very healthy food, and it contains some omega 3's. But there isn't anything extraordinary about it. Just like the "2 apples a day diet" (where you have an apple for your mid-morning snack and afternoon snack), adding fruit to your diet can help you lose weight because it's filling you up with (fairly) low calorie, high fiber bulk. Whether you choose to eat lots of acai, apples, or blueberries (also very healthy), increasing your intake of fruit will always help.
The best weight loss advice is the oldest. "Eat REAL food. Not too much. Mostly plants."
Fill up on REAL food, fresh fruits and veggies. Drink lots of water. If you need a caffiene fix, coffee or tea is better than soda. Make at least half of your carbs whole grain (whole wheat instead of white bread, brown rice instead of white rice, whole wheat pastas, OATS -scottish oatmeal or even just Cheerios etc.) Eat less cheese and meat - keep those portions low (it's easier if you've already filled up on salad and veggies and other super healthy foods) Keep healthy snacks around, like hummus and whole wheat pita crisps, raw walnuts straight out of the bag, or peanut butter on whole wheat crackers. Have a big spinach salad before dinner (or other leafy greens). Throw on some tomatoes and carrots. Make some black beans and serve it over the brown rice (That's my five-year-old's favorite meal) or just get some black bean chili from the health food aisle.
And get at least a little exercise - make sure it's something you enjoy or it won't stick. I take the kids to the park and play the "monster game" - I chase them, they run, and if I catch them, they get tickled until they beg me to stop. If you need something more serene, a walk at sunset (or sunrise if you're an early bird - I'm not.) can be a great stress buster.
Try not to focus too much on the weight alone - make small steps to improve your overall health, and don't be too hard on yourself. A glass of red wine at dinner, a chocolate truffle here and there, small indulgences keep your from feeling deprived. When you feel deprived, you're more likely to binge and completely fall off the wagon.
BABY STEPS! Good luck.
