Gender breakdown is nearly equal, with just a couple more males members. As comparison, the National Weight Control Registry is 80% female.
The average age of AWLR members is 40.6, with a median value of 39, with a standard deviation of 12. Our youngest member is 15 years old, while the oldest is 81.
The distribution of education is skewed towards higher education, an expected finding for an online survey. Nearly 40% of members have a bachelor's degree and nearly 30% boast a graduate degree.
Race continues to be heavily skewed towards those who categorize themselves as 'White.' However we now have over 100 members who are of Asian descent and over 70 that are Native American.
The majority of our registry members makes $40,000 or more each year, which is expected given the education distribution above.
The average height was 67.9 inches (5'8") which is almost identical to the average of males and females around the world. The median was 68, with a standard deviation of 4.03.
Side effects during transition to low carb or paleo
While transitioning from a normal or high carbohydrate diet to one with less carbohydrates, side effects were similar to those of any minor withdrawal. Weakness, headache irritability, GI symptoms. Weakness, headache, or no reported side effects were the most common. However constipation and hypotension are other things to look out for when starting your new way of eating.
Including all study subjects, regardless of their initial goal for changing their way of eating, the average weight loss was 30.5 with a median weight loss of 25. The standard deviation was 26.9. 300 pounds was the most weight anyone lost. On the other extreme, the most weight gained was 78 pounds. Many subjects changed their eating for improved athletic performance, improved health etc and did not try to lose weight, which may explain the enormous variation.
How frequently weighed self
Over 30% of study subjects weighed themselves every day. About 20% weighed themselves once a week.
Eating plans followed
The best represented diet continues to be the Primal Blueprint. The paleo diet in general is close behind, with Atkins a distant third.
