Limit sweetened beverages

Encourage eating together along with family

Practice your child to have food along with the family members and try to avoid the TV, computer, or video games at mealtimes. Sitting alone can encourage overeating and distract kids from their satiety signals. By eating along with family, your child will have mindful eating where they can focus on and enjoy their food. Ensure not to give one kid a special meal and everyone else has pizza this is because when they see you on the couch eating ice cream, they will want to do the same. So in the process of weight reduction ensure to have the same food that you are giving to your kids.

Limit take-out and eating out

Avoid making your child clean their plate

Ensure to allow your child to eat until full and not force them to clean their plate. This is because making them chela their plate will teach them to override fullness cues. While serving food remember one thing children don’t need as much food as adults consume. Kids always require a small portion of food and if they say they are full allow them to stop eating. But at the same time ensure that they intake enough food that their stomach requires.

Ensure they get enough good quality sleep

Lack of sleep will also lead to weight gain. Not getting enough sleep will increase the level of ghrelin, the hormone which is responsible for appetite. Less sleep might also rob your child of the energy to exercise during the day and encourage a craving for sugary foods for quick energy.
