Hi xxjessicax17x, Welcome!
For sure, like Jane said, read on the website for understanding of the Atkins' Deit. You don't really just double your carb count to 40 gms. Also, there is a very nice variety in food choice, so you don't have to stick to tuna and egss to have the best optimim weight loss.
There are some things you won't be able to eat during induction like apples, carrots, breads potatos and any sugar, for example. The Atkins paper back is about $5.00.
It explains how to have foods on hand for the times you're wanting to eat something, or feel like your losing energy. It also has the history and gives you some information on how to handle people who tell you things about the diet that are simply not true. The book and the website have so many good tasting recipes that are are very satisfying.
If you need to lose 5 lbs or 100 lbs...it's a plan and a way of eating that you can choose to do. It sounds like you checked it out and like it. But like any diet or plan, you have to stick to it to keep your weight off. I like it better than any diet because I get to eat foods I love and I don't get hungry and weak like I have on other diets. I do better when I stick to 20 gms. I've never lost my energy for the near 4 years while following this plan. I lose energy when I go off of it and eat something like pizza, sugar desserts and snacks. Please let us know how it's going for you! Hope to see you in the daily thread here! There's a lot of wonderful supportive people here.
