Everyone loses differently. Some do lose better at higher carbs. It's not just about how fast you can lose though.

The question with staying at 20g is are you willing to do that forever? If you do 20g until you reach goal then suddenly try to move to maintanance level carbs, you will retain water weight if nothing else.

Moving up the carb ladder helps your body build a tolerence to carbs again. It also helps itentify any trigger foods or food intolerences. Some people can't handle dairy, while others find fruit sets off sever cravings. It's also important to figure out what level of carbs you can tolerate. It's easier to move up slowly, then hit goal and then try to play guess the amount.

I try to keep on induction levels most of the days but incorporating other foods than those that are allowed for induction: berries, 1/2 cup of yogurt, ricotta cheese,
watermelon, etc.
Some days I get 30-35 g of carbs.

I'm still taking in about 20-25 carbs a day, but I have added some yellow vegtables and a very few frankenfoods (Lil Smokies). I tried adding green, red and yellow peppers and onions but suffered from terrible heartburn, so I had to eliminate them. (Hadn't eaten them for years, and was sorry to find I still can't tolerate them.) I doubt I will increase to more carbs until I am closer to goal. And I still haven't made up my mind if I am going to lower my goal weight, either. I really like this WOE and am eating a lot healthier now.

for those wanting to up their carbs... may i suggest flax-plus cereal + soymilk (unsweetened)... each serving of cereal + soy = 14carbs (already taking away the fibre)... a great breakfast!

i'm eating 60carbs a day and losing around 1lb a week... less than 10lbs to goal
