[2] Contrary to popular belief, not all cells require insulin in order to transport glucose inside of a cell. Some organs and tissues are insulin-independent, meaning insulin is not required, whereas others are insulin-dependent, meaning they require insulin. [3] GLUT 4 transporters are located on skeletal muscle, adipose tissue, and the heart and do require insulin. In order for glucose to be transported into these cells, insulin must bind to insulin receptors and signal for this process to occur. Insulin is produced by beta cells in the pancreas in response to high blood glucose levels. Once it is released, it binds to insulin receptors and triggers a response to allow glucose to be transported into the cell.

If insulin is not produced sufficiently, glucose is unable to enter insulin-dependent cells and these cells can starve. This is known as type 1 diabetes mellitus. If insulin is produced sufficiently, but receptors are damaged or are insulin resistant, they can not signal to allow glucose transport, and again cells become starved for energy. This is known as type 2 diabetes.

how to start my keto diet

To simplify: fiber is a type of carb, but you can’t digest it; rather, it feeds the healthy bacteria in your gut. Starch is more like long chains of sugar molecules connected together (envision a sugary pearl necklace), and your body breaks starch down into individual sugar pearls or units. [3]Simple CarbsRefined white flour is simple carbsSimple carbohydrates have one or two sugar molecules. Fructose (the fruit sugar) or glucose have one sugar molecule, whereas disaccharides like lactose (the milk sugar) and sucrose (table sugar) are made up of two. [4]Simple carbs come from added sugars like white and brown sugar and honey and from naturally occurring sugars found in milk and fruits. Refined grains and foods like white rice and white flour have been stripped of most of their nutrients and contain mostly sugar rather than starch or fiber, leading to a high blood sugar spike that would kick you out of ketosis. These simple carbs are absorbed into the bloodstream almost immediately. [5]Complex CarbsComplex carbs (polysaccharides or oligosaccharides) have three or more sugar molecules. Compared to simple carbs, complex carbs are more slowly absorbed into your bloodstream. Examples of complex carbs include:PotatoesCornParsnips and starchier veggiesLegumes and beans like chickpeas and kidney beansWhole grains like bread, breakfast cereal, rice, and quinoaWhat About Low-Carb Grains?Some keto professionals and advocates believe grains, in general, aren’t suitable for a ketogenic diet. In contrast, others say it depends on the grain, how often you eat it, and the person.

Counter: The keto diet is higher in fat-rich foods as the metabolic state of ketosis uses fat for fuel instead of carbohydrates which will help your body turn into a fat burning machine. While it could be higher in saturated fat based on how one employs the keto diet, it may not necessarily be the case. Even if one’s keto nutrition plan is higher in saturated fat, recent research shows that mortality from cardiovascular disease does not decrease with the reduction of dietary saturated fat. [18] In fact, studies show that replacing saturated fat with carbohydrates is associated with an increase in cardiovascular disease risk. [19]The American Heart Association suggests that total dietary fiber intake should be 25 to 30 grams per day, while the average American consumes only 15 grams per day. While the keto diet typically allows for no more than 50 grams of total carbohydrates per day, most of the allotted carbohydrates come from fibrous carbohydrates. For example, one can consume a cup of cooked spinach, two cups of chopped romaine lettuce, two cups of cooked broccoli, and ½ cup of raspberries in one day to achieve a total of 46 grams of carbohydrates, and whopping 24 grams of fiber. More fiber is likely to be added by way of other keto-friendly foods such as nuts, seeds, avocado, and dark chocolate. Keto is certainly not limited in the calcium department either—this myopic statement was likely made only because milk is not allowed on the keto diet due to its sugar content. Other high-calcium foods such as sesame seeds, Chia seeds, cheese, plain yogurt, sardines, canned salmon, almonds, and leafy greens are part of the ketogenic diet.
