Out of 498 people who have signed up for Round 4 of 90days, 180 people have checked in for Week 2. Let’s take a look at how things have changed for us over since the start of the round.
Overall weight distribution
Here’s the initial weight distribution of everyone who signed up originally and those who have checked in for Weeks 1 and 2:
And if we look at only the people who have checked in for Week 2, we get:
|(lbs)||Week 0||Week 1||Week 2|
|(kg)||Week 0||Week 1||Week 2|
Although it’s still hard to see the shift in the charts above, we’ve lost an average of 3.55 lbs (1.61 kg) per person over the last two weeks. As a group, we’ve lost a total of 639 lbs (290 kg)!
Fitting our weights to a normal distribution, it’s a little easier to see the slight shift in our group weight:
Weight distribution by gender
Let’s break this down by gender again. Looking at only the people who checked in for Week 2, there were 97 women and 83 men.
The weight distributions for both genders are shown below.
Women have lost an average of 2.98 lbs (1.35 kg) each since the start of the round, or a total of 289 lbs (131 kg) lost for these 97 women!
Men have lost an average of 4.22 lbs (1.91 kg) each since the start of the round, or a total of 350 lbs (159 kg) lost for these 83 men!
Distribution of weight change
Here’s the distribution of weight change since the start of the round for everyone who checked in.
Broken down by gender:
Are any diets or exercises doing better than others?
On the sign-up form, there was a page of optional questions about which types of diets or exercises we were planning on following. This data isn’t necessarily very accurate, because there is no guarantee that a person actually follows the diet or exercise that they said they would. Plus, the questions were optional, so not everyone answered them. Still, it’s fun to look at some of the info that we can get from this.
On the following plots, the average weight lost is shown for each group of people. Note that some groups have very low check-in counts. The average values are more meaningful for the larger groups.
Who’s still with us?
On the following plots, the people who checked in for Week 2 are compared with the people who did not check in. The plots are ordered by percentage of people retained. For example, of the 242 people who listed their goal as “reduce body fat percentage,” 90 people checked in (41%). But only 2 out of the 5 people who chose “gain weight” checked in (29%).
