( CNN ) -- With the one-track mind of a 6-year-old , Logan interrogated his mother , Jenny Spencer . Why are the other moms skinnier than you ? he asked at the park . If you took weight loss pills , would you be skinny ? he wondered during a TV infomercial . Spencer brushed off his questions . He was 6 and curious about the world around him . She was exhausted , trying to care for two young boys and her husband , who had chronic health issues . Her own health had fallen to the bottom of the to-do list . But Logan 's last question hit her like , well , the elephant in the room . If you got skinny , would you be able to play with me ? `` My heart broke , '' Spencer wrote on iReport . `` And from that moment forward , I began the transformation into a healthier lifestyle for my children . '' When Spencer stepped on the scale in June 2012 , the number 200 came as no surprise . More than a dozen people had asked her over the past few years whether she was pregnant . Two had rubbed her belly when there was no baby at all . The extra weight caused pain in Spencer 's hips when she walked , and the doctor warned that she was on the verge of type 2 diabetes . She had tried dieting after her second son , Brody , was born . Weight Watchers helped her drop 10 pounds , but she quickly gained 20 back . Her sister , `` a health nut , '' encouraged her to try different cleanses . All left her feeling like a failure . She was depressed , anxious and overwhelmed . `` You know , I started every Monday dreaming I could change my life , '' Spencer remembered . `` It was nearly a decade of that . '' Logan 's question made her realize she was missing her sons ' lives -- and her own . Spencer started counting calories , keeping her daily total under 1,500 . She also began going on short walks around the block and parked her car in the farthest spot from the grocery store door . A few months later , Spencer and her husband separated . But instead of using food to cope with the rush of emotions as she once would have , Spencer turned to exercise . `` I used that as more motivation to stay healthy for the boys , '' she said . `` My goodness , if I 'm going to have to do this on my own and be an example for them , I have to be strong . '' Working out was difficult at first ; the pain in her hips prevented her from moving very far , very fast . But over time she joined a walking club at work and started strength training one or two days a week . She focused on losing just 5 pounds at a time , because the thought of losing 60 pounds to reach a healthy BMI was intimidating . Reaching each smaller goal inspired her to keep going . By March 2013 , she had lost 64 pounds . `` When you 're that heavy , you feel like you 've lost hope , '' Spencer said . `` When you finally reach your goal , it 's the most amazing thing . '' Every Sunday , the Spencer family goes on a 10-mile bike ride near their home in Aurora , Colorado . They eat no-sugar cereal and skim milk for breakfast , Lean Cuisine meals or veggie smoothies for lunch , and lean protein with vegetables and brown rice for dinner . Water is Spencer 's `` secret weapon . '' Her diet has become a lifestyle . She 's careful about what she eats but allows herself treats in moderation . Deprivation is not the way to keep the weight off , she knows . Spencer 's energy is up , and her pain is gone . But the happiness she feels ca n't compare to the joy on her sons ' faces when she joins them on the playground . `` I am able to take my kiddos to the park and actually play with them instead of sitting on the sidelines . ''
Jenny Spencer put her health on the back burner while caring for two kids and her son . Spencer 's son asked a question that made her realize she was missing out on life . She reached her goal weight in March and has regained her weight loss .
