WELCOME Krissy, Jocaro, and Riley!!
Krissy, when you're feeling like you need a little something to keep you going, try to eat some protein. I find that works so much better for me than sugar. Protein will cause a smaller increase in your insulin response, and you won't "crash" soon after eating it like you will with sugar. Try things like a spoon of peanut butter, a handful of nuts, a hardboiled egg, or a slice of cheese....
Jocaro, if you do eat the low carb bars, be sure to really take a look at the ingredients. I know some of them are filled with saturated fat and trans fats (partially hydrogenated oils). This WOE (way of eating) is not only about eating the right kinds of carbs but also about eating the right kind of fats. And you're right, from what I've heard they do slow down the weight loss for some people.
Riley, I love your name! It's the same name as the black dog in my avatar! (NOT saying you're a dog
)
