11 year old me, too. I grew 6" in about 4 months but I only weighed about 60lbs when I was done because I was super tiny to start. My mom said our food bill roughly doubled that summer because I was eating about 4 servings at every meal. Could’ve fit my scrawny ass in that 100% off section probably and then gone ham on a buffet.
When I was 14, I grew 10" that year. At the end of the year I was 6’0 tall and weighed 145lbs.
We did a Calorie counting unit in PE that year in school. I was eating on average 6,000 calories per day across 8 meals.
