I'm using the Digest Diet (through Reader's Digest) and I've lost 17 lbs since January 13!!!
I have no real idea why, but this one made sense.... lots of healthy recipe ideas in the books... lean meats and veggies, limiting the simple carbs... (some complex carbs are ok...)
The best thing is that I can start the day with a really yummy smoothie... yogurt, frozen strawberries, peanut butter, coconut milk, flaxseed meal, dry milk powder, 1 tsp unsweetened cocoa powder, honey, vanilla, and a few ice cubes..... it tastes so good that I feel that I am cheating on the diet!
I'm lucky, though... for the most part, it is just hubby and I... so I can decide what is bought and brought into the house for the family. My daughter and her family are living with us for a few weeks, so that has made it a bit harder... but for the most part, I'm still maintaining the weight and still losing a bit here and there.
One important part... no artificial sweeteners, no diet drinks... that really doesn't help any.
