Even if you eat the same thing and exercise, it’s harder to lose weight as you get older. As aging progresses, your metabolism slows down, and frequent get-togethers, overtime work, and childcare are also fatigued, which make it a good state to gain weight.
+20s
If you are in your 20s, one of the main factors that interfere with diet is alcohol. Because it's a good age to hang out with friends and drink. If you drink a lot of alcohol and need to control your weight you should choose alcohol that is as low in calories as possible. There are many types of cocktails that contain sweet ingredients, such as soda, so people who are trying to control their weight should be careful.
+30s
The age at which muscles and skin lose elasticity and begin to gain weight is in 30s.
For women, pregnancy, childrearing, work stress, and time pressure make it
more difficult for women to control their weight. In particular, a woman gains
weight when she is pregnant, but if she had a normal weight before pregnancy, she should manage so that she does not gain more than 15 kg.
+40s
Even if you are not a person who eats a lot, you will continue to gain weight at this age.
This is because the levels of progesterone and estrogen, the hormones associated with menopause, become more severe. So, it's time to pay close attention to calorie intake and exercise. A lean, protein-based diet helps build muscle, so you should focus on vegetables and healthy protein.
+50s
As you reach this age, your metabolism slows down dramatically, and fat builds up in your stomach. That doesn't mean you're going to go hungry, though. Reduce your calorie intake, but not necessarily reduce the amount you eat. It is recommended to eat foods that are high in water and low in calories so that you feel full.
