Does restricting food make children want it more?

Research shows that by making foods unavailable they become more attractive. To test this we took a classroom of four and five year olds and examined their reaction to restricted treats over the week.

First, we had to find two foods that all the children were nonplussed about- we tested them with a range of dried fruit snacks and mangos and raisins were equally indifferent in the children’s preferences. Then the fun began. Every day, at snack time, we put the two bowls of snacks side by side and told the children that on the first whistle they had 15 minutes of unrestricted access to the mango. At the second whistle they had only five minutes of snack time to eat the raisins.

"there was a stampede to reach the forbidden fruit"

We watched the children day by day as the mango fell out of favour and the kids began cravin’ raisins. To begin with the children snacked voraciously on the mango but were more excited when it was raisin time. By the end of the week there was a stampede to reach the forbidden fruit, and the mango was looking less and less attractive.

The same kids who were indifferent to both snacks at the beginning of the week couldn’t get enough of the raisins by the end.

So, by restricting snacks you may have the adverse effect of making your children desire them even more and even encourage them to hide their snacking habits.

how to find your BMR?

BMR means Basal Metabolic Rate. It is used to estimate how many calories you should consume.By using a simple formula called the Harris-Benedict principle, you can assess your BMR.

  • Women: BMR = 655 + (4.35 x weight in pounds) + (4.7 x height in inches) - (4.7 x age in years)
  • Men: BMR = 66 + (6.23 x weight in pounds) + (12.7 x height in inches) - (6.8 x age in years)
  • If you are sedentary : BMR x 1.2
  • If you are lightly active: BMR x 1.375
  • If you are moderately active (You exercise most days a week.): BMR x 1.55
  • If you are very active (You exercise daily.): BMR x 1.725
  • If you are extra active (You do hard labor or are in athletic training.): BMR x 1.9
Create a Calorie Deficit:
Lose at a Healthy Rate:

Your BMR is the amount of energy your body needs to function. Then, to lose weight, you'll need to cut calories or burn extra calories and shoot for a level lower than the results you get with this formula.

We use about 60 percent of the calories we consume each day for basic bodily functions such as breathing.Other factors that influence your BMR are height, weight, age and sex.

Step One : Calculate your BMR with the following formula:

Step two : In order to incorporate activity into your daily caloric needs, do the following calculation:

In order to lose weight, you must create a calorie deficit. It is easier and healthier to cut back your calorie intake a little bit at a time.

Every 3,500 calories is equivalent to 1 pound.

If you cut back 500 calories a day, you will lose 1 pound per week.

If you exercise to burn off 500 calories a day you will also lose 1 pound per week.

Ideally, you should do a combination of both, (e.g. cut back 250 calories; burn an extra 250 calories).

A healthy weight loss goal is to lose 0.5 to 2 pounds per week. Losing more than 2 pounds per week will mean the weight is less likely to stay off permanently. Never cut back to fewer than 1,200 daily calories without medical supervision. To find out how you are spending your current calorie intake, keep a detailed food diary for at least one week.

Making little changes like these will really add up in the long run.
