These bars (and shakes) are infamous stallers for many people, no matter what the Atkins sales dep. says.
As for sweet treats, part of this WOE - especially Induction - is to wean our bodies from sugar cravings, so my best tip would be to just drink more water. Have some Chromium or L-Carnitine supplement (helps regulating your blood sugar levels, hence keeping those cravings at bay). Some people rely on SF Jello with a dollop of whipped heavy cream on top for an occasional snack.
I have not incorporated any "LC junk food" at all yet into my WOE, no pizza, no muffins, no nuthin.
Don't intend to either. I'm on pre-maintenance now, so once in a while I will treat myself to a slice of Wasa crisp bread (sesame/wholewheat), 4g netcarbs with tons of butter and gouda cheese on top to go with a soup or so. Or half a cup of brown rice now and then.
On OWL I started introducing snacks such as almonds or unshelled peanuts etc. (Carefully though, some people stall on nuts and they're highly addictive to some - as almonds is for me...) And once in a while, a 10g piece of Lindt Excellence 85% cocoa chocolate bar (2 netcarbs). Just for the pure cocoa kick - cocoa is a natural "upper". I never have more than that 10g square though. The high cocoa amount is satisfying enough anyway. SF candy I stay away from like the plague if I can. (Sugar alcohols can give heavy belly pains, diarrhoea etc.)
Another OWL/pre-maintenance snack I have "on special occasions" is a mix of 2 tbsp of 10% fat Greek yoghurt, 2 tbsp creme fraiche (34% fat), 1 tbsp crushed almonds, some liquid sweetener, vanilla essence and cocoa. Makes a yummy dessert, close to Italian ice-cream in style.
But try to give yourself and your metabolism a chance to purify, before you start experimenting with these or similar options. That way it will be so much easier for you to keep to the right "treat" levels in the future.
I used to be able to down a whole 200g milk choco bar in the past.
is all I can say to that now... Would never dream of doing that again, my whole body chemistry has changed.
