Welcome,
Glad that you found this forum which has 15 years of low carb related information well organized into sub-forums, as zoo girl wrote...look around at the different topics to help you understand why low carb is a healthy way to lose weight and to live well. Read some success stories and milestones for inspiration. http://forum.lowcarber.org/forumdisplay.php?f=86 Check the health topics if any apply to you. http://forum.lowcarber.org/forumdisplay.php?f=81 since you are worried about cholesterol, the DrHarcombe post in the heart disease forum is a classic. http://forum.lowcarber.org/showthread.php?t=466506 There are many other resources in that topic.

If you would rather read a book, the 2010 edition of Atkins written by 3 doctors delved into the science more than any other edition, My favorite for a general introduction is Why We Get Fat by Gary Taubes. These two books may help you understand why low carb is healthy.

Another website for good low carb health information is https://www.dietdoctor.com/low-carb. This one page with all its details is an excellent introduction, also check under the Health tab for more specific information. How LC works section answers some of your questions. https://www.dietdoctor.com/low-carb/how-it-works The free part of the site offers everything needed, but a free one month trial of the membership side would add more video explanations. Read the success stories on his site too...that lack of hunger when doing low carb correctly, and the increase in energy, is one of the first results most often remarked on. The lack of hunger is one reason why I like Dr Westman's clinic plan to start, based on what Dr Atkins used in his clinic, and in Why We Get Fat. https://www.dietdoctor.com/se/wp-co...starch_diet.pdf. You can eat fat and protein "to satiety" as long as the carbs are kept below 20g total carbs, and no trigger foods like nuts are allowed. The DietDoctor intro plan is also based on it if having recipes would help you, but you can also buy whatever "allowed foods" you like and eat them until full. Dr Westman video course under How it works.

I completely agree that you need to feel comfortable that this way of eating is the healthiest diet for your conditions. Read, and then read some more. Ask questions. Let us know how we can help you. All the best,
