The bad side of skipping meals (pt 2)
Skipping meals can result in; decreased energy expenditure, decreased metabolic rate, weight gain, increased preference of fat in the diet, decreased strength, increased injury rates, decreased bone density.

Other effects are decreased body temperature, decreased resistance to disease, decreased testosterone level, raised blood cholesterol, ulcers, mood swings and menstrual dysfunction.
How the body reacts
Any time you skip a meal, your body goes into a “fasting mode”. During this fasting, carbohydrates, proteins, and fats are all used for energy.
Carbohydrates are the number one source of fuel, followed by fats and then protein.
As the fasting continues, the glycogen (glucose storage) deposits found in the liver and muscle become depleted. As the glucose levels drop, the body looks for other sources of fuel.
In efforts to produce energy (glucose), fats are broken down.
This process results in the production of ketone bodies which are also then broken down and absorbed into the Krebs cycle to produce energy.
This process can cause the following negative effects on the body; nausea, fatigue, constipation, lowered blood pressure, elevated uric acid, stale taste in the mouth, and foetal harm/stillbirth in pregnant women.
In this same state of using ketone bodies for energy, the body begins to reduce energy output in an effort to protect both fat and lean tissue.
In addition, as the lean tissues begin to shrink, they become weaker and perform less metabolic work, reducing energy expenditure even more.
Hormones also slow down metabolism to conserve lean body tissue. This is also known as “starvation mode”.
This mechanism is thought to have evolved as a defense against starvation. When metabolism slows down, fewer calories are needed and weight loss slows down.
So in effect, skipping a meal in order to lose weight will rather lead to no weight loss.
These effects not desirable
Skipping meals and restricting calories will create cravings. Rapid high blood sugar occurs when you give in to these cravings.
Also you might end up eating fatty foods (pastries and ice cream) which may result in too much consumption of fats.
When glycogen stores are depleted and not being replaced because you have not eaten, your body goes into a low energy state.
Unfortunately, the weight that is lost (after skipping meals) is mostly water and muscles.
There is slowed metabolism when you skip meals. This means that your body will have a tough time digesting food. Since you would get so hungry later in the day, you are likely to eat more than one meal’s worth at one sitting.
The already slowed metabolism is going to take a lot longer to work the oversized meal throughout your body. This will rather result in weight gain.
The success rate of losing weight from skipping meals is relatively poor. A significant amount of weight may be lost at first, but once again this is water and muscle weight, and the chances of gaining the weight back, plus more is quite good.
A final word
Dietary restriction by skipping meals should be avoided. The insufficient energy imbalance has undesirable effects, such as increased fat storage and weakened performance.
The depressed metabolism will conserve its energy, making dieting less effective and more difficult.
Using this method in hopes to lose weight may become frustrating and result in even more unhealthy ways of dieting.
It has been proven that consuming sufficient calories is better than not getting enough. In addition, getting calories on time, thus preventing energy deficit state during the day, is better than getting them late.
Be sure to eat all meals throughout the day. They do not have to be huge meals, but enough to get your metabolism going.
Eat well stay healthy. You are blessed!
