Hello,
I used a combination of Wonderslim and Medifast products to lose 70+ lbs in 2008. I'm back to using Wonderslim products again, because I don't eat meat or poultry (I do have an affinity for shrimp), and it's the easiest way for me to follow a low carb/high protein plan.
In my first week of restarting my diet, I've lost 6 lbs. How much weight you lose depends on a variety of factors, including your starting weight, how many calories you consume, and how much exercise you're getting. My first 70 lbs was lost over 4 months; I consumed 6 meals per day, 800 cals, and walked on a treadmill for 30 mins once a week. Some weeks I lost only 2 or 3 pounds, while one week I lost as much as 8. I'm not really sure why my weight loss varied so much.
While I mostly consume the shakes, I highly recommend the Nacho Cheese Pastas, the Biscotti (not a Wonderslim product, but something sold by Diet Direct), Sloppy Joe, and Chocolate Cake for days you crave "real" food.
If you have any additional questions, feel free to ask. Best of luck if this is the route you choose!
