But for some kids, puberty may not start until 12 or later for girls and 14 or later for guys. Whenever you start puberty, it may take 3 or 4 years for you to fully develop and gain all the weight and muscle you will have as an adult.
“Obesity incidence starts increasing in one's twenties and peaks at 40 to 59, and then decreases slightly after age 60,” says Craig Primack, MD, an obesity medicine physician at the Scottsdale Weight Loss Center in Arizona.
Our children are supposed to gain weight
Other than the first year of life, we experience the most growth during adolescence. Between the ages of 13 and 18, most adolescents double their weight. Yet weight gain remains a sensitive, sometimes scary subject for parents who fear too much weight gain, too quickly.
Our metabolism slows down as we age.
But you really can't always blame it on the body clock. Metabolic decline may cause you to gain 10 to 15 pounds, but not 40 or 50 pounds. That's lifestyle.”
More significant weight gain is normal during the preadolescent ages of roughly 9 to 12 and adolescence – as a child matures into a young adult. It's not unusual for the body to store fat during this time as it prepares for the rapid growth and changes associated with puberty.
Lean body mass in girls diminishes from approximately 80 percent to 75 percent by the end of puberty, while the amount of body fat increases. In comparison, the percentage of lean muscle mass in boys increases from about 80 percent to 90 percent by the time they reach adulthood.
Children are considered underweight when their body mass index (BMI) is below the 5th percentile for their age and gender on growth charts, according to the CDC study. If a child is underweight, the pediatrician may ask more about medical history or could order testing to check for undiscovered health issues, Dr.
Study shows that younger people and women are more likely to put on extra pounds. A study that examined the long-term weight gain of more than 13,800 U.S. adults found that on average, people gained about 17 pounds between their twenties and thirties.
The finding of the study suggests that people in middle age certainly gain weight and it is harder for them to lose it, but slow metabolism is not the real reason behind it. It was revealed that from the 20s to the 50s the energy expenditure is the most stable.
According to the Centers for Disease Control and Prevention (CDC), most 13-year-old girls weigh around 76–148 pounds (lb) and most 13-year-old boys weigh between 75 and 145 lb, but this can vary widely. The average weight of a 13-year-old will depend on a number of factors.
Puberty – Increased hormones in a child's body during puberty (between the ages of 10 and 14 for girls and between the ages of 12 and 16 for boys) leads to growth and possible expansion of “baby fat” areas. This typically takes place in girls' belly, breast area and hips. Boys' shoulders will get broader.
Noticeable weight gain may occur prior to a growth spurt as excess fat helps promote growth. As a child goes through puberty, their stores of body fat may change.
As people gain weight, excess fat tends to be centered around the abdomen, generally starting at the lower abdominal area and working up. This results in a large belly or gut protruding out from the rest of your body.
A combination of things happens as we age. We tend to lose muscle mass, so our abdominal muscles aren't as tight as they once were, and the loss of elastin and collagen in our skin allows gravity to have its way so skin starts to sag. Both can cause the waistline to expand.
Many women also notice an increase in belly fat as they get older — even if they aren't gaining weight. This is likely due to a decreasing level of estrogen, which appears to influence where fat is distributed in the body.

To put it bluntly: "Women and men of average height need to gain or lose about about 8 and 9 pounds, respectively, for anyone to see it in their face, but they need to lose about twice as much for anyone to find them more attractive," lead author Nicholas Rule told Medical News Today.
Crash dieting
Transitioning from a very low calorie and low carbohydrate diet to a low calorie and moderate carbohydrate diet often leads to a weight gain of 1-2 kgs in a matter of one day. This is mainly because of a sudden increase in the carbohydrate content which is stored along with water in the body.
Despite it all, not every change you'll face in your mid-twenties is negative. Whether you've been rocking curves since puberty or have noticed more curves as of late, the body will likely go through some visible changes around this age–and yes, that's a good thing.
In your late 20's you may also notice your body becoming curvier than it was in your early to mid 20's. Due to metabolic and hormonal changes, some women experience increased body fat, making them naturally curvier.
During your early 20s, skin is experiencing its first major transformations. This is the golden age for your skin's health and appearance because collagen production is thriving — AKA why your face looks so glossy and bouncy all the time.
Puberty in women normally occurs between 11 and 14 years of age. If a child reaches a particular weight (around 45 kg or 100 lb), the onset of puberty is triggered. The heavier the child, the earlier puberty occurs, possibly affecting risk of later disease.
Muscle is denser than fat, and as it is more compact within your body, as you gain muscle mass, you end up looking thinner, no matter your physical weight. So, if you've been doing a lot of strength training lately, it's likely this is the reason that you're looking fantastic but not dropping those numbers.
Women carrying a male fetus have significantly increased maternal weight gain during pregnancy when compared to women with a female fetus. The increased sex ratio remains when adjusting for each newborn weight group.
