There are three basic units the body uses for energy:
All three can be converted to blood glucose. However, while fats and proteins are converted slowly, carbohydrates are converted quickly causing quick spikes in the body’s blood sugar levels. These spikes in blood sugar levels cause the pancreas to create and release insulin until the blood sugar level returns to normal.
Meanwhile, insulin, a hormone produced in the pancreas that lowers our blood’s glucose levels is released into the blood as soon as the body detects that blood sugar levels have risen above its optimal level.
Insulin is a very efficient hormone that runs the body’s fuel storage systems. If there is excess sugar or fat in the blood insulin will signal the body to store it in the body’s fat cells. Insulin also tells these cells not to release their stored fat, making that fat unavailable for use by the body as energy.
Since this stored fat cannot be released for use as energy, insulin very effectively prevents weight loss. The higher the body’s insulin levels, the more effectively it prevents fat cells from releasing their stores, and the harder it becomes to lose weight. According to many authorities, over the long term, high insulin levels can lead to insulin resistance and cause serious health problems like the ones listed below:
Carbohydrates, especially simple carbs like sugar and starch, are quickly turned into sucrose by the body entering the blood stream quicker thereby causing the release of large amounts of insulin. The fewer carbs are eaten, the less insulin is produced by the body, and the fewer calories are stored as fat. Less fat storage equals less weight gain and fewer carbs eaten equals less insulin in the blood and the body using its fat stores for fuel.
The premise behind every low-carb diet plan is that a body that produces less insulin burns more fat than a body that produces lots of insulin. Some plans encourage a period of extremely low carbohydrate intake so that the body will enter a state of ketosis and more quickly burn fat stores - These are usually called induction periods.
Secrets to Healthy Weight Gain
There is so much emphasis on weight loss in todays culture that it is easy for people to forget that many out there are actually people out there trying to gain weight, not lose it.
Childhood Obesity
Along with the increase of obesity in adult, childhood obesity is on the rise. Around 15.5 percent of adolescents in the United States, aged 12 to 19 are obese. Even more alarming, about 15.3 percent of children ages 6 to 11 are obese. These children are developing Type II Diabetes and high blood pressure at an early age. They are placing themselves at increased risk for heart disease and other obesity-related diseases. Their weight also makes them the target of bullies and children who insult and taunt them about their weight. This can ruin their self-esteem and put them at risk for depression.
Calculating Your Calorie Needs
In order to eat fewer calories than you need, you have to determine how many calories you actually need. Adults can calculate their approximate energy needs using the following formula:
