How does insulin make me fat?
Most people know when they are putting on weight as they have an area of your body that you notice it first appear. This will hopefully help you understand why this happens and why you can’t always burn off that access weight in your training program.
Insulin is the main player in fat storage here’s how it works.
What is insulin?
Insulin is a hormone that is released from the pancreas in response to elevated blood sugar (glucose).
Insulin is crucial to life in the proper amounts, but is detrimental in excessive amounts. Over half the population of the western world produce too much insulin because of their dietary standards.
Insulin’s primary role in the body is to keep blood sugar within a “comfort zone”. Throughout the day blood sugar rises and falls outside this comfort zone many times and when it does insulin is called upon to restore balance.
How does insulin work?
It is important that your blood sugar levels do not rise too high or too quickly. High blood sugar levels will alert the pancreas, the pancreas then detects this excess glucose and secretes insulin, which then lowers the blood sugar by shifting the metabolism into storage mode. Insulin coverts this excess glucose into glycogen (the stored form of glucose), removes it from the bloodstream and stores it in the liver and muscles. The excess blood sugar that cannot by stored as glycogen will be converted into new fat and stored in the adipose tissues (visibly on your hips, butt, back and man boobs) – everyone is different and generally has an area of your body that you first notice an increase in fat, women is normally thighs and men gut.
Excessive insulin release and weight gain:
While carbohydrates are a vital source of fuel for the body, if you eat too many of them, they will ultimately be stored as fat. The muscles are able to store three to four hundred grams of carbohydrate while the liver cans only store sixty to ninety grams. Once these levels have been reached, the carbohydrates are converted to fat and stored in the body’s fatty tissues. Also, if you eat foods that are high in carbohydrates, you will cause the body’s blood glucose levels to rapidly rise, and to compensate for this rise, insulin is secreted into the bloodstream in order to lower the blood glucose levels.
The issue with this is that higher levels of insulin prompts the body to store the excess carbohydrates as fat because it needs to be stored as quickly as possible, as well as telling it not to release any of the stored fat, meaning that you are unable to use existing stored fat as energy. High insulin levels also suppress glucagon and growth hormones. Glucagon promotes the burning of both fat and sugar by the body while growth hormone is used to build new muscle mass and also for muscle development.
Insulin also causes hunger and one of its nicknames is actually the “hunger hormone”. This is because the blood sugar levels increase after a meal that contains carbohydrates, causing insulin to rise as well in order to lower blood sugar. This results in hunger (often only a couple of hours or less since your last meal) as your blood sugar levels are lower than what you need. The more refined the carbohydrates you eat, the more extreme the response is. This is because refined carbohydrates lack the fibre that helps to minimise the insulin response – fibre causes the blood sugar levels to rise at a steadier rate.
Insulin resistance:
Insulin resistance is a huge problem that will have adverse affects with weight loss. In an average person, 40 percent of the carbohydrates that they consume are converted into fats. This percentage may be much higher in a person that is suffering from insulin resistance.
Some of the common complaints that are associated with insulin resistance are:
• fatigue
• difficulty concentrating or poor memory
• low blood sugar
• intestinal bloating
• sleepiness
• increased fat storage and weight
• increased triglycerides
• increased blood pressure
• depression
• in higher cases all of the above
What happens with insulin resistance is that the levels of insulin in the blood are similar or a little higher than a normal person’s, but the body’s cells become resistant to the insulin, causing the body to over-secrete insulin in order to feed the cells. The cells respond sluggishly to the glucose, causing blood sugar levels to be higher than they should be, and when the body cannot get the glucose into the cells, the extra energy is stored in fat cells, making it easy for insulin resistant people to gain weight but difficult for them to lose it.
Insulin resistance is higher in overweight and inactive people. Overcoming insulin resistance requires a COMPLETE OVERHAUL of your situation, changes to your diet, significant weight loss along with regular exercise is required to improve your sensitivity to insulin which will lower your chances of developing type 2 diabetes.
Ways to increase your insulin sensitivity and avoid insulin resistance:
Insulin sensitivity is a term used to describe people who require relatively normal or low levels of insulin to process glucose.
If you have high insulin sensitivity, the body will regulate your blood sugar a lot faster (under an hour) however if you have high resistance to insulin the body will take hours to regulate causing cravings along the way that will further inhibit regulation.
The best ways to help insulin sensitivity and prevent insulin resistance are to avoid:
• Foods high in sugar
• Sugar in general
• Milk
• Processed foods
• White rice and pasta
• Some fruit
• Fructose syrups
The best ways for regulating your blood sugars levels are to eat foods high in protein like meats, poultry, fish and eggs. Plus good fats that are found in avocado, nuts, flax seeds, coconut oils, Fish oils and cinnamon.
Eating good fats and protein will keep your blood sugar levels balanced, avoiding spikes and troughs.
Summary:
The goal is to keep your blood sugar levels stable and to stay relatively close to your bodies “comfort zone” level. When this occurs the body is able to efficiently burn fat is primary source of energy.
If you can maintain stable blood sugar levels for 90% of the time weight management is a lot easier to achieve. For the other 10% of the time it is good to “shock” your body by going outside the comfort zone and eating a treat that will raise the blood sugar to require insulin to come to the rescue. You can’t eat the same foods over and over, you body will adapt to all the good and bad that they contain, so you need to remind your body from time to time by throwing something new in.
