How Does Protein Affect Blood Sugar


Can You Eat Too Much Fiber

Effect of Protein on Blood Sugars

Yes, it is quite possible to eat too much fiber, which can cause bloating, gas, and constipation.;

How much too much is varies from person to person, but a good guideline is that the uncomfortable side effects of excessive fiber can occur when someone eats more than 70 grams of fiber a day. People with very sensitive digestive systems can experience side effects much sooner than that, after eating as little as 30-40 grams of fiber in a day.

For most people, eating too much fiber is not a concern as only an estimated 5 percent of Americans even meet their daily recommended fiber intake.

However, eating 70 grams of fiber in a day is really not difficult and will often happen for people who eat many high-fiber nutrition bars or follow a vegan diet so its worth keeping an eye on your fiber intake if you experience frequent bloating or constipation.

There Are Too Many Rules In A Diabetes Diet

MYTH. If you have diabetes, you need to plan your meals, but the general idea is simple. Youâll want to keep your blood sugar levels as close to normal as possible. Choose foods that work along with your activities and any medications you take.

Will you need to make adjustments to what you eat? Probably. But your new way of eating may not require as many changes as you think.

Protein Throughout The Day

The American Diabetes Association advise people with diabetes to space their meals out during the day and not to skip meals or to eat too much.


The body can only absorb and use so much protein at one time. It uses what it can and then creates waste with the leftover.

Instead of having 50 g of protein in one meal, for example, it is better to spread that 50 g out into three to four meals containing 15-20 g each.

A protein shake with added oatmeal, yogurt, and fruit could make a meal.

It is also important to vary your sources of protein.

Protein shakes can act as a protein supplement, but it is still important to eat a variety of protein foods, such as meat, fish, dairy produce, nuts, and beans, as these provide other essential nutrients.


There are different types of protein shake. Some you can make from a protein powder, while others come ready to drink.

Both of these can contain sugar, artificial sweeteners, and unnecessary chemicals.

People with diabetes should take care to limit sweeteners like sugar, agave, or fruit juice in their shakes.

How Much Protein Should I Be Eating

The UK Food Standards Agency has a sliding scale for recommended protein intake, varying by age:


  • 1 to 3 years: 15g
  • 4 to 6 years: 20g
  • 7 to 10 years: 28g
  • 11 to 14 years: 42g
  • 15 to 18 years: 55g
  • 19 to 50 years: 55g
  • Over 50 years: 53g

Some diets, such as the Zone diet, advocate eating an amount of protein in proportion to your lean body mass .

S: Selection Of Relevant Studies

How Does Protein Affect Blood Sugar?

There are many human studies available on high protein intake and insulin sensitivity. However, comparing these studies is difficult. This is mainly due to differences in the control diet used, duration of the study, energy balance, that is, with or without weight loss, the source and amount of protein used and differences in the type of subjects included: non-obese, overweight, non-diabetic and diabetic subjects. Comparing studies can be made easier when studies are organized by those factors. For the first part of this overview article, recentâyear 2000 and onwardsâhuman intervention studies were selected in which a dietary protein content of >20 energy percentage was used and which measured insulin sensitivity. The present review aims to give a broad overview on the subject, but it does not intend to be a complete systematic review. Furthermore, for a better comparison, studies were arranged by the duration of the intervention: short term versus long term . Within these topics, a distinction was made between the type of subjects prescribed the diets, followed by interventions with weight loss. For all studies mentioned, the amount of protein is expressed as En% considering that a high-protein diet refers to a protein content of >20 En%. For a summary of the studies cited in this overview article on the effect of high-protein diets on insulin action in humans, see .

You Can Adjust Your Diabetes Drugs To Cover Whatever You Eat

MYTH. If you use insulin for your diabetes, you may learn how to adjust the amount and type you take to match the amount of food you eat. But this doesn’t mean you can eat as much as you want and then just use additional drugs to stabilize your blood sugar level.


If you use other types of diabetes drugs, don’t try to adjust your dose to match varying levels of carbohydrates in your meals unless your doctor tells you to. Most diabetes medications work best when you take them as directed. When in doubt, ask your doctor or pharmacist.

A Balanced Diet For Diabetes

Controlling blood sugar is about adopting a healthy and balanced diet. Increasing protein, in balance with healthy carbs like fruits, vegetables and whole grains, can help improve blood sugar.

Adding a whey protein shake for breakfast or as a mid-afternoon snack is a convenient and tasty way to do something amazing for your body and blood sugar. If you do decide to add a whey protein shake, make sure it is low in sugar to get the most benefit. Whey protein is a great addition to a diet for diabetes that can help control appetite, promote weight loss and improve insulin sensitivity.

Protein And Kidney Damage

Kidney damage is a complication that can affect as many as 40% people with diabetes. Kidney damage in diabetes can be diagnosed by testing for ketones the presence of protein in the patients urine.


People with diabetes who have, or are at risk of, kidney damage may be advised to lower their consumption of protein.

Diet Foods Are The Best Choices

Does Eating More Protein Raise Blood Sugar?!

MYTH. You might be paying more for “diet” food that you could find in the regular sections of the grocery store or make yourself.

Read the labels to find out if the ingredients and number of calories are good choices for you. When in doubt, ask your doctor, diabetes educator, or a dietitian for advice.

What Foods Contain Fiber

There are two types of dietary fiber, and one can have more impact on your blood sugar than the other. Many foods contain both types of fiber, which is why you can never assume that the total grams of dietary fiber in food wont raise your blood sugar.


Soluble fiber: This type of fiber dissolves in water to form a thick gel-like substance in the stomach, explains the FDA. It is broken down by bacteria in the large intestine and provides some calories.

  • Beans and peas
  • Nuts and seeds
  • Carrots

Insoluble fiber: This type of fiber does not dissolve in water. Instead, it passes through your digestive system and isnt broken down, which means it doesnt supply your body with additional calories.;

  • Fruits
  • Vegetables
  • Wheat bran
  • Whole-grain foods

There are no good or bad fibers. Both types of fiber are beneficial to your health and you should aim to eat a variety of high-fiber food. Just be aware that soluble fibers will impact your blood sugar.

You’ll Need To Give Up Your Favorite Foods

MYTH. Thereâs no reason to stop eating what you love. Instead, try:

  • A change in the way your favorite foods are prepared. Can you bake it instead of deep-frying it?
  • A change in the other foods you usually eat along with your favorites. Maybe have a sweet potato instead of mashed potatoes?
  • Smaller servings of your favorite foods. A little bit goes a long way.
  • Not using your favorite foods as a reward when you stick to your meal plan. Do reward yourself, but with something other than food.

A dietitian can help you find ways to include your favorites in your diabetes meal plan.

What Happens In Your Body After Eating Proteins

Unless youre counting calories in the name of healthy eating, you may not care much about what happens after scarfing down your favorite cheese-baked pork chops hey, its a protein-rich meal, right?

As a matter of fact, protein consumption doesnt impact your overall blood glucose levels much . Still, the amount of protein you eat affects the insulin levels in your body.

The Role Of Insulin In Protein Synthesis

The Top 12 Foods to Balance Blood Sugar Levels

Aside from regulating the absorption and breakdown of ingested proteins, insulin also plays a part in protein synthesis. The hormone encourages cells to take in alanine, arginine, and glutamine. Note that the process will only happen when the above-mentioned amino acids are present in sufficient quantities in your body. The rate of protein synthesis only increases when amino acid delivery to the muscle cells speeds up .

An interesting thing to note is that BCAAs, being essential amino acids, were once thought to influence muscle protein synthesis. But scientific evidence says otherwise.


According to the American Journal of Physiology-Endocrinology and Metabolism, insulin does not stimulate muscle protein synthesis when more BCAAs are present than usual. This suggests that other non-BCAA essential amino acids, for example, tryptophan and threonine, may be the triggers for insulin-induced protein synthesis. Another possible reason may be that insulin also stimulates protein absorption after eating. This lowers the concentration of non-BCAA amino acids, making it more unlikely for protein synthesis to occur. Further findings also confirm that when there are enough non-BCAA essential amino acids, insulin will initiate muscle protein synthesis in the presence of increased BCAAs.

Carbohydrates Are Bad For Diabetes

MYTH. Carbs are the foundation of a healthy diet whether you have diabetes or not.

They do affect your blood sugar levels, which is why youâll need to keep up with how many you eat each day. Some carbs have vitamins, minerals, and fiber. So choose those ones, such as whole grains, fruits, and vegetables. Starchy, sugary carbs are not a great choice because they have less to offer. Theyâre more like a flash in the pan than fuel your body can rely on.

Protein And Your Health

Protein is one of three essential macronutrients; the other two;are fat and carbohydrate. These are needed in large amounts to maintain health and vital functions.


The body uses protein to build, repair, and maintain most of your body’s tissues and organs. Proteins are also necessary for immune system function and help some additional physiological processes as well.

Apple Peanut Butter And Dark Chocolate

For a sweet treat with health benefits, Andrea Conner, RD, recommends munching on apple slices with all-natural nut butter and dark chocolate shavings. The cholesterol-lowering soluble fiber in the apple slows down stomach emptying and may result in a more moderate rise in blood glucose, while the peanut butter provides a great balance of protein and monounsaturated fat that helps with satiety and better blood-sugar control, says Conner. A sprinkling of dark chocolate chips adds some decadence, which will satisfy sweet cravings without spiking blood sugar.

What Is Blood Sugar

Does Protein Increase Blood Sugar? | Barbara McDermott – SHIFT Formula

Blood sugar, also known as blood glucose, comes from the food you eat. Your body creates blood sugar by digesting some food into a sugar that circulates in your bloodstream.

Blood sugar is used for energy. The sugar that isnt needed to fuel your body right away gets stored in cells for later use.


Too much sugar in your blood can be harmful. Type 2 diabetes is a disease thats characterized by having higher levels of blood sugar than whats considered within normal limits.

Unmanaged diabetes can lead to problems with your heart, kidneys, eyes, and blood vessels.

The more you know about how eating affects blood sugar, the better you can protect yourself against diabetes. If you already have diabetes, its important to know how eating affects blood sugar.

Your body breaks down everything you eat and absorbs the food in its different parts. These parts include:

  • carbohydrates
  • fats
  • vitamins and other nutrients

The carbohydrates you consume turn into blood sugar. The more carbohydrates you eat, the higher the levels of sugar youll have released as you digest and absorb your food.


Carbohydrates in liquid form consumed by themselves are absorbed more quickly than those in solid food. So having a soda will cause a faster rise in your blood sugar levels than eating a slice of pizza.

Fiber is one component of carbohydrates that isnt converted into sugar. This is because it cant be digested. Fiber is important for health, though.

What Is The Influence Of Dietary Protein On Post Meal Blood Glucose

Does protein effect blood sugar after a meal? Is there additional math we need to do for improved control after meals?

At present, those of us who use intensive insulin therapy understand how proper mealtime insulin dosing requires appropriate carbohydrate counting. This is based on the thought that carbohydrate is the main nutrient that influences our post meal blood sugar values. However, studies have demonstrated that protein and fat may also play a role in what happens to our post meal blood sugar.

The impact of dietary protein on blood sugar has long been a topic of debate. Early research hypothesized that 100 g of ingested protein produced 5080 g glucose. Later research showed, it was only ~ 10 g of glucose that showed up in the circulation following consumption of 50 g of protein . This equates to ~ 1 g of glucose produced from every 5 g of protein consumed. The results of the study below are consistent with this and, indicate consumption of ~ 75g and 100 g of protein ALONE may produce late rises in blood glucose which is similar to that from 15 and 20 g of glucose. This is relevant, given that 20 g of consumed glucose causes significant post meal excursions when insulin is NOT given. However, because the impact from protein is delayed and sustained it shows a good reason we need consider dosing for protein dependent on portion consumed.

How Much Protein Do We Need

People need to eat the right amount of protein each day.

From the age of 19 years, the 20152020 Dietary Guidelines for Americans recommend a protein intake of between each day depending on the persons age and sex. Protein intake for adults should account for 10 to 35 percent of their daily calories.

Protein intake is not the same as protein-rich food intake.

According to Choose My Plate, these protein recommendations equate to between 5 and 6.5 ounces of protein-rich food each day. One ounce could be, for example, one egg, one ounce of meat or fish, or a tablespoon of peanut butter.

Research suggests that endurance athletes may need more protein than healthy adults who do not exercise.

One study has proposed that people who do endurance training should consume 1.2 g to 1.4 g of protein per kilogram of body weight each day.

Some bodybuilders and athletes consume extra protein to increase muscle composition, but protein alone does not increase muscle. People have to do the work in the gym to see any result.

Protein shakes can help athletes maintain their protein levels, whether or not they have diabetes.

    What Is Dietary Fiber

    Often referred to as roughage, dietary fiber is part of the total carbohydrate amount in most plant-based foods.;

    It is a type of carbohydrate found in plant foods and is made up of many sugar molecules linked together, explains the Food & Drug Administration. But unlike other carbohydrates , dietary fiber is bound together in such a way that it cannot be readily digested in the small intestine.

    In laymans terms: most forms of carbohydrate are easily broken down into glucose and absorbed through the lining of your stomach, but the majority of dietary fiber you eat is not. Which also means it doesnt generally raise your blood sugar.
