The Truth to Detox Diets
There are certainly better ways for you to drop a few pounds.
Detoxification, or cleansing, diets
aim to rid your body of disease-causing "toxins" by limiting the types and amounts of food you can eat. Some plans permit nothing except certain fruits and vegetables (which are often spun into juices), while the popular Master Cleanse fast restricts you to a cayenne pepper-laced elixir for 10 days.
Since the daily calorie count for many detox plans tops out at 700, you will slim down if you follow them, says David Grotto, R.D., founder of Nutrition Housecall, a personal- consulting company in Elmhurst, Illinois.
But
the weight you'll lose will consist of water and lean muscle tissue rather than body fat. And don't expect to be thinner for long: Because these detox diets put your body into starvation mode, it hangs on to every calorie to conserve energy. The loss of lean muscle mass dampens your calorie-burning furnace as well. So once you revert to your old eating habits, says Grotto, your metabolism will have slowed down, making you even more likely to regain the weight. Vitamin deficiencies are also possible, especially with the plans that limit fruits veggies.
What's more, the whole concept of detox diets is misleading and it's a better strategy to stick to a balanced healthy diet. "Your liver and other organs naturally remove so-called waste from your body," says Grotto. "Eating whole grains, produce, healthy fats, lowfat dairy, and lean protein keeps these organs and your body's elimination process in top condition. If you cut your calorie intake to 1,500 daily, you'll lose weight, too."
It is also important to keep in mind that your body needs a certain amount of calories to sustain bodily funtions. Here is the formula for
basal metabolic rate
: this tells you how many calories your body needs to funtion
This number describes how much energy your body needs to function while resting. These functions include heart beating, the lungs breathing, the eyelids blinking and the body temperature stabilized. Your BMR is responsible for 60-70% of the calories you burn in a day. Men typically have a higher BMR than women. The Harris-Benedict formula is one of the best ways to determine your BMR:
- Adult Male: 66 + (6.3 x body weight in lbs.) + (12.9 x height in inches) - (6.8 x age in years)
- Adult Female: 655 + (4.3 x weight in lbs.) + (4.7 x height in inches) - (4.7 x age in years)
