Are You Feeling Tired and Sluggish After Eating?Ready to nap right after a big meal? This is a normal response to an influx of carbs (think of that post-Thanksgiving dinner feeling). But if it happens often, your body may be sending a message that your diet is too diabetes-friendly.
After eating, all carbohydrates -- whether in a doughnut or a carrot -- are broken down into the bloodstream as glucose (blood sugar), the body's main energy source. When the blood containing the glucose hits the pancreas, this organ gets the message to release insulin, a hormone it produces to help the cells throughout the body use glucose. Cells have insulin receptors that allow glucose to enter and either be stored as future energy or used right away.
It's a great system. But a diet that's high in simple carbs like sugar, white flour, and sweet beverages -- especially when consumed in large quantities at one sitting -- overwhelms it
What helps you: Slow your carb load. Choose more complex carbohydrates, such as whole grains (barley, oats, quinoa, spelt, brown rice), vegetables, and whole fruits (not juices) that the body has to work harder to digest. This means blood sugar stays stable longer. Move around right after eating -- take a 15-minute walk; even washing the dishes helps -- rather than plopping in front of the TV. The activity will help your body begin to process the big glucose intake faster and more efficiently.

Obesity is a medical condition in which excess body fat has accumulated to the extent that it may have an adverse effect on health. It is defined by body mass and further evaluated in terms of fat distribution via the waist–hip ratio and total cardiovascular risk factors. Body mass is closely related to both percentage body fat and total body fat. In children, a healthy weight varies with age and sex. Obesity in children and adolescents is defined not as an absolute number but in relation to a historical normal group, such that obesity is a Body mass greater than the 95th percentage.
What is Obesity:
Obesity is a medical condition in which excess body fat has accumulated to the extent that it may have an adverse effect on health, leading to reduced life expectancy and/or increased health problems. People are considered obese when their body mass , a measurement obtained by dividing a person's weight in kilograms by the square of the person's height in metres, exceeds 30 kg/m2.
Obesity increases the likelihood of various diseases, particularly heart disease, type 2 diabetes, obstructive sleep apnea, certain types of cancer, and osteoarthritis. Obesity is most commonly caused by a combination of excessive food energy intake, lack of physical activity, and genetic susceptibility, although a few cases are caused primarily by genes, endocrine disorders, medications or psychiatric illness. Evidence to support the view that some obese people eat little yet gain weight due to a slow metabolism is limited; on average obese people have a greater energy expenditure than their thin counterparts due to the energy required to maintain an increased body mass.
A case study led to the prediction that if we do not take appropriate measurements to curb the increasing obesity problem and raise alarms, then by the year 2015, 2.3 billion adults will face the problem of being overweight and 700 million adults will face the problem of obesity. This in turn, will affect the economy of the health systems and associated elevation in the medical costs for the insurers.

Several hundred soda studies have been published over the last two decades, but most of the ones done in humans (as opposed to mice or rats) relied on people’s memories of what they drank. In the latest bad news for the soda industry, Danish researchers discovered that drinking non-diet soda leads to dramatic increases in dangerous hidden fats.
Soda is one of society’s favorite beverages. Each year, billions of gallons of soda are sold in the United States alone. Though it is popular with men, women, and children, many experts believe drinking soda may have serious health consequences.
Some studies have suggested a link between drinking soda and obesity. Soda is high in sugar and calories. Combined with its practically nonexistent nutritional value, soda may cause drinkers to pack on the pounds without receiving even the smallest nutritional benefit. Surprisingly, drinking diet soda has been linked to weight gain as well. However, some experts assert that obesity may be caused not by drinking soda, but by the combination of drinking soda and leading a sedentary lifestyle
Drinking soda has been shown to contribute to tooth decay. Spokesmen for the soda industry have conceded this point. Interestingly, in recent years, levels of tooth decay in the United States and similarly developed countries have decreased. This is in spite of the fact that more people are drinking soda than ever before. At the same time, levels of obesity have risen.
Obviously, the sugar consumption involved in drinking soda is cited for causing tooth decay. However, the acid in soda has been shown to erode tooth enamel, leading to dental cavities as well. In fact, the acid in soda can begin damaging enamel just 20 minutes after drinking soda.
|Water Is Life|
1. Drinking Water Helps Maintain the Balance of Body Fluids. Your body is composed of about 60% water. The functions of these bodily fluids include digestion, absorption, circulation, creation of saliva, transportation of nutrients, and maintenance of body temperature.
"Through the posterior pituitary gland, your brain communicates with your kidneys and tells it how much water to excrete as urine or hold onto for reserves.
When you're low on fluids, the brain triggers the body's thirst mechanism. And unless you are taking medications that make you thirsty, you should listen to those cues and get yourself a drink of water, juice, milk, coffee -- anything but alcohol.
"Alcohol interferes with the brain and kidney communication and causes excess excretion of fluids which can then lead to dehydration.
2. Water Can Help Control Calories. For years, dieters have been drinking lots of water as a weight loss strategy. While water doesn't have any magical effect on weight loss, substituting it for higher calorie beverages can certainly help.
"What works with weight loss is if you choose water or a non-caloric beverage over a caloric beverage and/or eat a diet higher in water-rich foods that are healthier, more filling, and help you trim calorie intake,Food with high water content tends to look larger, its higher volume requires more chewing, and it is absorbed more slowly by the body, which helps you feel full. Water-rich foods include fruits, vegetables, broth-based soups, oatmeal, and beans.
3. Water Helps Energize Muscles. Cells that don't maintain their balance of fluids and electrolytes shrivel, which can result in muscle fatigue. "When muscle cells don't have adequate fluids, they don't work as well and performance can suffer," These guidelines recommend that people drink about 17 ounces of fluid about two hours before exercise. During exercise, they recommend that people start drinking fluids early, and drink them at regular intervals to replace fluids lost by sweating.
4. Water Helps Keep Skin Looking Good. Your skin contains plenty of water, and functions as a protective barrier to prevent excess fluid loss.
"Dehydration makes your skin look more dry and wrinkled, which can be improved with proper hydration," he says. "But once you are adequately hydrated, the kidneys take over and excrete excess fluids."
You can also help "lock" moisture into your skin by using moisturizer, which creates a physical barrier to keep moisture in.
5. Water Helps Your Kidneys. Body fluids transport waste products in and out of cells. The main toxin in the body is blood urea nitrogen, a water-soluble waste that is able to pass through the kidneys to be excreted in the urine, "Your kidneys do an amazing job of cleansing and ridding your body of toxins as long as your intake of fluids is adequate.
If you chronically drink too little, you may be at higher risk for kidney stones, especially in warm climates, Guest warns.
6. Water Helps Maintain Normal Bowel Function. Adequate hydration keeps things flowing along your gastrointestinal tract and prevents constipation. When you don't get enough fluid, the colon pulls water from stools to maintain hydration -- and the result is constipation.
"Adequate fluid and fiber is the perfect combination, because the fluid pumps up the fiber and acts like a broom to keep your bowel functioning properly.
These Are A Few Tips To Help You Drink More WaterIf you think you need to be drinking more, here are some tips to increase your fluid intake and reap the benefits of water:
- Have a beverage with every snack and meal.
- Choose beverages you enjoy; you're likely to drink more liquids if you like the way they taste.
- Eat more fruits and vegetables. Their high water content will add to your hydration. About 20% of our fluid intake comes from foods.
- Keep a bottle of water with you in your car, at your desk, or in your bag.
- Choose beverages that meet your individual needs. If you're watching calories, go for non-caloric beverages or water.
