The Backstory On Intermittent Fasting

How Do You Get Diabetes?

IF as a weight loss approach has been around in various forms for ages, but was highly popularized in 2012 by BBC broadcast journalist Dr. Michael Mosleys TV documentary Eat Fast, Live Longer and book The Fast Diet, followed by journalist Kate Harrisons book The 5:2 Diet based on her own experience, and subsequently by Dr. Jason Fungs 2016 bestseller The Obesity Code. IF generated a steady positive buzz as anecdotes of its effectiveness proliferated.

As a lifestyle-leaning research doctor, I needed to understand the science. The Obesity Code seemed the most evidence-based summary resource, and I loved it. Fung successfully combines plenty of research, his clinical experience, and sensible nutrition advice, and also addresses the socioeconomic forces conspiring to make us fat. He is very clear that we should eat more fruits and veggies, fiber, healthy protein, and fats, and avoid sugar, refined grains, processed foods, and for Gods sake, stop snacking. Check, check, check, I agree. The only part that was still questionable in my mind was the intermittent fasting part.

Putting Your Plan Into Action

While you should be able to eat most of the same things as everyone else, people with diabetes often have to limit the amounts they eat, prepare food in different ways than they may have been used to, and think about when they eat.

Consider the issue of consistency: If you have diabetes, you need to eat about the same amount every day, and at about the same times. You shouldn’t skip meals, or go more than four or five hours without eating during the day.


Another important element of a healthy diet is portion control. Your health-care team can help you learn to gauge correct portion sizes, which are often smaller than we’ve come to expect in the age of super-sizing. For example, one serving of meat is about the size of a deck of cards, and a serving of pasta is about the size of half a tennis ball.

How Does A Poor Diet Contribute To Hypoglycemia

Eating infrequently, skipping meals, not consuming enough carbohydrates and eating low-fiber/high-sugar carbohydrates can contribute to low blood glucose levels.

When blood sugar levels rise quickly, such as with drinking sugary soft drinks, they tend to drop because they are digested rapidly.

When a meal is more balanced , digestion can occur more slowly, which promotes more stable changes in blood sugar.

A diet to help prevent hypoglycemia is essentially a healthy, balanced diet that everyone could benefit from.


There arent any side effects of eating in this balanced way, nor are there side effects from eating consistently and avoiding sugary foods and beverages.

If anything, an adjustment in lifestyle and preferences would be the only side effect, and just like any other change, it becomes easier once you adopt it as a lifestyle.

Foods That Fight Diabetes

Pritikin eating means focusing on whole foods that are naturally rich in fiber and naturally low in fats, sugars, and industrial refinement. Pritikin foods are vegetables, whole fruits , whole grains, legumes such as beans and peas, nonfat dairy foods, and moderate servings of lean meat such as fish, skinless chicken breast, and game meat like bison and venison.

Diagnosing Diabetes In Cats

If You Taste This Unexpectedly, You May Have Diabetes ...

After a physical exam and discussion of your cats symptoms, your veterinarian will take blood and urine samples for testing.


In addition to checking the glucose levels in your cats blood and urine, your vet will be checking for evidence of other diseases that have symptoms similar to diabetes, like kidney disease and hyperthyroidism.

They will also check for conditions that can complicate the treatment of diabetes, like infections and diabetic ketoacidosis, which require hospitalization.

How Diet Affects Hypoglycemia

Hypoglycemia is a condition that can be avoided by eating a balanced diet and consuming regular meals and snacks.

When a person with chronic hypoglycemia eats regularly and focuses on foods that promote steady blood sugar levels, the frequency of low blood glucose levels will likely decrease.


This will improve their quality of life and reduce the risks of hypoglycemia.

Its also important to consider how exercise can affect blood sugar levels and plan meals and snacks accordingly.

Exercise can lower blood sugar. Therefore, if youre prone to hypoglycemia, its even more important to consume a fiber-rich carbohydrate, preferably with some protein as well, before and after being active to avoid low blood sugar.

What It Means For Your Dog To Be A Diabetic

For the diabetic dog, one reality exists. Blood glucose cannot be normalized without treatment. Although the dog can go a few days without treatment and not get into a crisis, treatment should be looked upon as part of the dogs daily routine. Treatment almost always requires some dietary changes. Whether an individual dog will require oral therapy or insulin injections will vary.

As for the owner, there are two important points: financial commitment and personal commitment.


When your dog is well regulated, the maintenance costs are minimal. The special diet, the insulin and syringes are not expensive. However the financial commitment can be significant during the initial regulation process, especially if complications arise.

In some cases, your dog will be hospitalized for a few days to deal with the immediate crisis and to begin the regulation process. The immediate crisis is only great if your dog is so sick that it has quit eating and drinking for several days. Dogs in this state, called ketoacidosis may require a week or more of hospitalization with quite a bit of laboratory testing. Otherwise the initial hospitalization may be only for a day or two to get some testing done and to begin treatment. At that point, your dog goes home for you to administer insulin. At first, return visits are required every 5 7 days to monitor progress. It may take a month or more to achieve good regulation.

How Long Can A Type 2 Diabetic Go Without Insulin

This is a complicated query, as many Type 2 diabetics do not require insulin. Going without insulin can lead a diabetic to develop ketoacidosis , which is potentially fata. Type 2 diabetics are very likely t be able to survive without insulin, especially if they are eating a healthy diabetic diet.

However, if a Type 2 diabetic has started using insulin as part of their diabetes treatment, going without it may be dangerous. Type 2 diabetics may develop hyperglycemia if they do not properly manage their blood glucose levels. It can take days or weeks for hyperglycemia to develop. If untreated, hyperglycemia can damage the kidneys, heart, eyes, and nerves.


Sometimes Diabetes In Cats Is Reversible It Goes Away

Rigorous diet can put type 2 diabetes into remission, study finds

With proper diet and the correct insulin therapy, a significant number of cats can go into remission or have their diabetes reversed.

We dont completely understand this, but we are getting better treatment results with low-carb/high-protein diets and early insulin intervention.

Diabetes is more common in male cats, and the statistics show that males have a slightly better chance of reversing their diabetes.

Anywhere from 3090% of cats will return to normal with early diagnosis and treatment.

Three Diabetes Diet Strategies: Basic Guidelines For People With Diabetes

Finding your way to a healthy diet can reduce the risks associated with diabetes. There are three main goals, according to the American Diabetes Association , so following these proven strategies will help you to:

1. Achieve a healthy body weight. Body mass index uses your height and weight to determine how much body fat you carry. A BMI of 18.5 to 25 is considered to be a healthy weight range with a healthy amount of body fat.Another measure: waist circumference is considered by many to be a better measure of excess abdominal body fat. A waist circumferencegreater than 40 inches for men, and above 35 inches in womenhas been shown to increase the risk of developing health problems such as type 2 diabetes, heart disease, and high blood pressure.

The closer you are to a healthy body weight or at least an acceptable waist circumference, the more likely you will be able to control and, possibly reverse your risks of diabetes.

Dont get overwhelmed by thinking about how much total weight you have to lose, Ms. Arevalo advises. Studies have shown that losing just 5-10% of your body weight will significantly improve your blood sugar levels as well as your cardiovascular health so set short-term goals of losing just 5-10 pounds to start.

What Complications Can Be Caused By Hypoglycemia

Passing out from low blood sugar because you have not recognized the early signs and symptoms is called hypoglycemia unawareness, and can be quite dangerous depending on where you are, explains Dr. Klonoff. As doctors are required to report such incidents to the Department of Motor Vehicles, it can also mean a suspended drivers license.


If this is something youre worried about, Wearing a continuous glucose monitor with an alarm for hypoglycemia can alert a person who is prone to developing low blood sugar levels that their blood glucose concentration is becoming dangerously low, so appropriate preventive action can be taken before they lose consciousness, explains Dr. Klonoff.

Why Should Diabetics Not Skip Meals

A skipped meal alters the balance between food intake and insulin production, and can cause your blood sugar levels to eventually drop. For diabetic people dependent on insulin or blood sugarlowering medication, skipping meals can be more dangerous because it can lead to low blood sugar, says Pearson.

  • Return for a glucose recheck in about one week. The recheck needs to be at or near the time your dog is due to get an injection of insulin. Do not make any changes in the feeding routine. Do not give insulin, but bring it with you.
  • Feed your dog one of the foods recommended by the veterinarian in the amounts that is recommended by the veterinarian. Feed dry food and canned food every 12 hours. Give the canned food after the insulin injection so your dog sees the canned food as a reward for taking its injection. After a few days, your dog will tell you when it is time for insulin by begging for its canned food.

    Its Strange That Blood Sugar In A Diabetic Can Rise Despite Not Having Eaten Anything Since Typically Eating Causes Blood Sugar To Go Up

    But its no uncommon occurrence that in diabetes, glucose or blood sugar levels can actually rise in the absence of eating.

    When we dont take food into our body for energy, our liver will try to help us by releasing glucose into our blood so we have the energy we need to stay alive, says Lucille Hughes, RN, CDE, director of diabetes education at South Nassau Communities Hospital in Oceanside, NY.

    For people with diabetes, the liver may release too much glucose, causing blood sugar to go up.

    This is why its so important for diabetics to regularly take blood sugar readings, even if they feel fine.

    The liver has hundreds of jobs. One of those jobs is to release glucose into the bloodstream for energy because the body requires energy to function, even when at rest.


    Basic bodily functions require energy and glucose provides that energy.

    In diabetes, things are out of whack in the body. The liver in the diabetic may sometimes overestimate how much sugar to release into the bloodstream.

    Or, to put it another way, the liver over-corrects the problem.

    The only way that a diabetic can stay ahead of this curve is to monitor their glucose levels on a regular basis throughout the day to make sure that the sugar level doesnt sneak its way into getting into a dangerously high range.

    Prevention Of Diabetes In Cats

    Diabetes cannot be prevented, per se, but the risk for cats getting diabetes can be reduced.


    Do not allow your cat to become obeseencourage exercise, feed cat-appropriate food and avoid long-term use of steroids if possible.

    If your cat does get diabetes, then the goal is to prevent complications from developing while also trying to reverse your cats insulin dependence through diet and exercise.

    Tips For Managing Hypoglycemia

    Changing eating habits and being mindful of how foods affect hypoglycemia is the best preventative measure people can take.

    Knowing the symptoms of hypoglycemia is also essential. Some people might not realize that they are having issues with low blood sugar levels until they are mindful of what hypoglycemia is.


    If lifestyle changes still dont reduce incidents of hypoglycemia, its important to speak with your healthcare provider.

    A person with hypoglycemia can try the following lifestyle considerations:

    • Eating frequent balanced meals. Eat small meals every 3 to 4 hours throughout the day, rather than 3 large meals per day.~
    • Avoiding foods high in saturated fats or trans fats.
    • Avoiding high sugar foods and sweetened drinks, including sweets, sugary drinks, and fruit juices with added sugar
    • Eating foods high in soluble fiber and lean protein
    • Reducing or eliminating processed and refined sugars from your diet.
    • Choosing complex carbohydrates over simple carbohydrates.
    • Choosing foods with low GI scores
    • Reducing alcohol consumption

    In the case of non-diabetic hypoglycemia, further investigation of the cause of recurrent hypoglycemia would be warranted if lifestyle changes dont improve the prevalence of chronic low blood sugar.

    How Did People With Type 1 Diabetes Survive Historically

    We hate to break it to you, but they didnt.

    Looking at historical records from pioneering diabetes doctors Joslin and Allen before the advent of medical insulin, we see that they were only able to keep patients alive for months, sometimes more than a year, by starving them to death. Literally.

    Dr. Elliott Joslin proudly wrote that, Whereas formerly the prognosis for children less than 10 years of age was measured in months, today it is rare for a child to live for less than one year. Ultimately, all of Joslins pre-insulin patients died. 100 percent of them. Those who didnt starve succumbed once their insulin production dropped to zero.

    But of course we now know that the onset of type 1 is a messy affair. The autoimmune process that drives it doesnt happen overnight. Insulin production lingers for many months in a phenomenon called the diabetes honeymoon.

    So, history can only show us how long we can suffer starved in the honeymoon phase of the disease, not how long a full-fledged type 1 will last sans insulin in todays modern world.

    DKA is the leading cause of death in people with T1D under age 24. But stats indicate that there are only several-thousand deaths from DKA per year in the whole country. Most cases occur right at disease onset, and most receive some sort of medical intervention in a timely manner. The

    Type 2 Diabetes Diet Plan

    According to the American Diabetes Association , a Mediterranean-style diet, a plant-based diet, and a diet known as Dietary Approaches to Stop Hypertension are all good starting points for a type 2 diabetes meal plan that can be modified to accommodate your personal eating preferences.

    These diet approaches have two important factors in common: mostly whole foods, and meals built around vegetables rather than carbohydrates .

    However, contrary to popular belief, a type 2 diabetes meal plan is not necessarily a low-carb diet, nor should it be a high-protein or very low-fat meal plan. In fact, ADA recommends less emphasis on specific requirements for proteins, carbs, and fats, and more emphasis on following a whole foods approach that focuses on the quality of your diet the less processed, refined, prepared, and fast foods focused, the better. Making a move towards eating more home-cooked meals may seem daunting, but just takes a little planning, especially with resources like the ADA’s Diabetes Food Hub.
