I know I''m not the only one who thinks about digging in to some oreos, a candy bar, or a bag of chips haha. Is it our body that craves things such a junk food, or after is it after our tongue tastes them that our brain makes us think that''s what we want? Because in my opinion, healthy fruits and veggies aren''t nasty they actually taste good but I don''t crave them as much.
What''s the Quickest Way to Lose Weight? - In One Week
Recommended Answer:
Our bodies can certainly crave unhealthy foods which typically are loaded with carbohydrates which easily convert to sugar. This basically comes about because of the sugar rollercoaster our body is on when we consume lots of carbs. We consume carbs, which quickly convert to sugar in our bodies. Insulin is produced to metabolize this sugar and out blood sugar level begins to drop. When the blood sugar level drops below a certain level we start to crave more carbs to raise blood sugar level again and the cycle repeats. Fat and protein do not convert to sugar so quickly so when you consume them you don''t go on the same rollercoaster ride. Your body is better able to maintain a more stable sugar level. Because of this, a low fat diet is often counterproductive for people trying to lose weight because those fat calories are often replaced with carbs which cause the rollercoaster and cause you to consume even more calories overall than if you if you consume fat.
You can probably develop cravings for healthy foods, but unhealthy foods are soooo much more accessible. They are conveniently packaged; often require no preparation; are tasty; and are everywhere. When you go to a movie theater your are offered popcorn and candy, and various other junk foods. I''ve never seen them offer a bag of carrots and broccoli and some hummus to dip it in.
- Our body craves sugars that break down quickly. Regardless of where it comes from.
- there addictive and taste sooo good
- Our bodies don''t, but our minds do. Sure, your tongue is part of your body, but the impulses go back to the mind. The brain tells it to salivate, not the tongue making itself do it.
"The mind, is more important than the body." Arnold Schwarzenegger- Still Pumping(pumping iron) - THE EVOLUTION OF CRAVING
Experts believe that cravings occur for a variety of reasons. They attribute them to evolution, psychological factors such as stress and unhappiness, and - sometimes - a genuine need for certain foods.
''It''s crucial to remember that a food craving is not simply hunger,'' says Professor Andrew Hill, Head of the Academic Unit of Psychiatry and Behavioural Sciences at Leeds University.
Hunger is the body''s way of making sure it is provided with energy, in the form of nutrients from food. When the stomach is empty, it releases the hormone ghrelin, which communicates with the brain''s command centre, the hypothalamus. This creates the feeling of hunger and is how we know when to eat.
Satiation is signalled by the release of the hormones leptin by fat cells, and insulin by the pancreas, in response to increased blood sugar.
Cravings, however, are much more complex. - I do not crave junk food in fact I don''t like it at all. You will only crave them if you get addicted to the high levels of sugar and salt. My preference is always for real food.
