Whats The Effect Of All That Fatty Meat On Your Health

Intermittent Fasting WITHOUT Keto? Is It Possible To Lose Weight?!?!?

And what happens, for example, after cutting down fruits, legumes and whole grains all food that studies point to reducing cardiometabolic risk?

Dr. Neil J. Stone, a preventive cardiologist at Northwestern Universitys Feinberg School of Medicine, worries about this, having seen the bad cholesterol levels of some of his patients on the keto diet increase drastically. Any diet that raises major risk factors for coronary heart disease puts patients at risk over the long term, he said.

An advisory Dr. Stone co-authored by the American Heart Association stated that lowering dietary saturated fat, like fatty meats and high-fat dairy, can be beneficial. And swapping it for unsaturated fats like safflower oil or olive oil may reduce the risk of cardiovascular disease. But before going on any diet, he recommends you ask yourself: What are your goals? Are they short-term or long-term? Can you get there without taking as many risks?

Stanfords Dr. Gardner also says he sees one common misconception about keto: eating too much protein. Most amino acids in protein foods can be converted into glucose in the body, undermining efforts to keep carb intake low. It drives me nuts that people dont get it, he said when he sees people eat, for instance, steak after steak.

The Benefits Of Longer Fasts

Fasting comes in many different forms. Some people go 16 hours without eating before they consume anything. Others may undergo complete calorie restriction for days at a time!

Along with entering ketosis, during the first 24 hours of fasting, your body can undergo some significant changes. For example, gluconeogenesis is stimulated during fasting, which increases the number of calories your body burns.

Moreover, a 48-hour fast may ramp things up further by helping to improve insulin sensitivity while also boosting the autophagic process.

How long is it safe to fast if you want to explore this tactic for several days? Longer fasts may introduce even more health benefits, especially when it comes to ketone production and reducing blood glucose levels. The 2019 study cited above even showed that subjects experienced an increase in physical and emotional well-being by engaging in prolonged fasting.

If You Need To Lose Weight A Diet That Focuses Mainly On When You Eat May Be A Good Way To Shed Pounds And Improve Your Cardiovascular Health

Anyone who’s tried different weight-lossdiets is probably familiar with their pitfalls. Low-calorie diets often leave you tired, hungry, and cranky. Low-carb or “keto” diets can cause cravings and constipation. Low-fat diets are also tough to follow and, contrary to popular belief, they do not seem to prevent cardiovascular disease.

Another diet trend, intermittent fasting, takes a different approach. Rather than limiting what you eat, this diet limits when you eat . For some people, that change may be easier to manage, says Dr. Eric Rimm, professor of epidemiology and nutrition at the Harvard T.H. Chan School of Public Health.

Short-term studies suggest that people stick to intermittent fasting diets as well as or better than they do to other diets. And according to a 2019 review article in the journal Nutrients, intermittent fasting promotes weight loss and may reduce risk factors linked to heart disease, including diabetes, high blood pressure, unhealthy blood lipid levels, and inflammation.

“However, we don’t have much evidence about how well this diet works over the long term,” says Dr. Rimm, noting that there are just two long-term studies of intermittent fasting, each lasting a year. Nor are there large populations of people who’ve followed this eating pattern for years. That’s in contrast to two other diets linked to a healthy heart and healthy body size the Mediterranean diet and a vegetarian diet.

Intermittent Fasting: The Basics

Intermittent Fasting &  Keto

There are many ways to practice intermittent fasting , but the basic premise is simple:

It starts with separating the day or week into fasting and eating windows. You then simply shorten your feeding window, and extend the window in which you consume little to no food..

Unless youre prone to a midnight snack, you already practice a short period of fasting overnight between dinner and breakfast.

The idea is that extending that fasted period on certain days of the week can bring about some interesting benefits. This could be as simple as using a 16-hour fasting window each day or opting for longer fasts once every week or two. One of the big plus points for fasting is that its easy to customize to your lifestyle.

Although IF may seem like a relatively new dietary trend, fasting is something that human beings have practiced for thousands of years.

Like many other predaceous animals, early humans would have naturally gone without food for prolonged time periods in between successful hunts. While this might seem less than ideal at first glance, natural periods of fasting would have likely put these early humans into ketosis. This may have imparted benefits like appetite reduction and mental clarity, which could have actually assisted them in getting through to their next meal and enjoying another successful hunt.

What Keto And Fasting Looks Like

We asked LIFE apps users to tell us how they combine intermittent fasting and a keto diet. Heres what they told us:

Cherie Louise follows a 20:4 fasting schedule. Her typical meal is steak and eggs with a leafy greens, haloumi cheese, Greek yogurt, and some berries.

Cassandre Soriaux fasts for 16 hours a day. She usually eats meat or fish, veggies and some raw milk cheese.

Evangeline San Diego follows an 18:6 regimen. She loves cauliflower rice plus Salmon or Pork. She also loves strawberries and avocado.

Morgaine Swann fasts between 18 and 22 hours most days. Her meals are usually steak, chicken or ham, cheese, sour cream or cream cheese, and broccoli or brussels sprouts. She snacks on almond butter, pecans, hazelnuts, almonds or peanuts, and occasionally indulges in rebel ice cream.

Pam Brockus fasts for 16-20 hours a day and occasionally does a 60-hour fast. She eats lean meat, raw veggies and cheese for lunch, and meat and veggies for dinner.

The above is not medical advice. Always consult with your doctor before trying a ketogenic diet, especially if you have type-1 or type-2 diabetes, or high blood pressure. A ketogenic diet with the intent of losing weight is not recommended for children. You shouldnt practice intermittent fasting or follow a ketogenic diet if you are pregnant or breastfeeding.

It Can Help You Avoid Keto Flu

If youre completely new to the keto diet, intermittent fasting can help you avoid some common uncomfortable side effects such as the keto flu. These uncomfortable side effects typically occur when your body transitions to a fat-burning state.

Now the question is, how can intermittent fasting negate keto flu?

Since keto flu commonly takes place when youre getting into ketosis , the quicker you get into ketosis, the less likely youll suffer from negative side effects. Since a short fast can help you get into ketosis faster, it can help reduce the likelihood youll suffer from keto flu.

Stages Of Intermittent Fasting

After reading a few articles online that talked about the stages of intermittent fasting, I decided to create my own classification:

  • The fed state: When you are eating, your blood sugar level increases and your body is using glucose for energy.
  • Early fasting state: About 4 hours after eating, your body is no longer digesting food. Your blood glucose and insulin levels start to decline.
  • Transition state: This state typically lasts from about 12 hours to 18 hours after the last meal. Your liver starts producing ketone bodies as it runs out of glycogen.
  • Light ketosis: You are officially in ketosis when your ketone level is at least 0.5 mmol/L. Light ketosis is when your ketone readings range from 0.5 mmol/L to 1.0 mmol/L.
  • Optimal ketosis: Optimal ketosis is when your ketone level ranges between 1.0 mmol/L to 3.0 mmol/L. I say optimal, but what is optimal always depends on your health goals. For the average woman this is the range where you will start feeling different. It is also the most effective range for weight loss.

    And What’s The Deal With Intermittent Fasting

    How Does Intermittent Fasting Work Faster Dr.Berg Shows 5 Tricks To Make IF Faster

    IF is a pattern of eating where you restrict foods and sweetened beverages for an uninterrupted period of time every day and then eat only during the remaining hours .

    You can pick your windows but we encourage people to eat when the sun is up and fast when the sun is down, says registered dietitian Amy Shapiro, founder of Real Nutrition. During fasting hours you can drink water, black coffee or plain tea, but nothing that provides calories or requires any sort of digestion or shift in hormones.

    The theory behind IF is that depriving your body of calories for an extended period of time forces it into a temporary state of starvation and slowed metabolism. This makes your fat cells burn glucose for energy and can lead to improved weight loss results. One plus is that you don’t necessarily need to cut out any foods to stick with IF. It’s really the slashing of calories in general that’s said to boost weight loss, and experts say there’s not one IF schedule that works better for losing weight over anotheryou can choose whichever one works best with your lifestyle.

    There are several different ways to schedule your fasting times, but the 16:8 version is the most commonly used. For people who are newer to IF, the 14:10 schedule might be easier to stick to, because you have a 10-hour eating window and only a 14-hour fast.

    Also something to note: IF is not recommended for people with a history of disordered eating, since it can get into pretty restrictive territory.

    What Is Intermittent Fasting Exactly

    First of all, fasting simply refers to the practice of avoiding food and calorie sources, like beverages with calories.

    In fact, aside from the unfortunate few who sleepwalk and raid the fridge, most people already fast 8 or more hours every night while sleeping.

    Intermittent fasting generally means any form of repeated, intentional fasting. IF means going beyond the normal sleep fast and actually delaying or skipping one or more meals on purpose.

    The name is slightly confusing, because many people intermittent fast every single day . Others dont intermittent fast daily, but still do so regularly.

    For now, just keep in mind that IF encompasses a wide variety of fasting practices. Well cover them more in-depth in a moment.

    On the other hand, IF doesnt include things like accidentally skipping a meal or forgetting to eat.

    Reasons for intermittent fasting include health or weight-loss goals, or both. Spiritual or religious fasting may have similar benefits, but people dont usually call them intermittent fasting.

    What Foods Are Excluded From The Keto Diet

    Because the keto diet focuses mainly on fat, many foods are excluded. Various foods have an abundance of carbohydrates, from fruits and veggies to grains and meats.

    Thus, if you’re considering adopting a keto diet for your lifestyle, be prepared to swap out some of these foods for alternatives higher in fat and lower in carbs.

    Pay Attention To Your Body

    Its okay to experiment with whatever youre doing and see what actually works best, because it is not exactly the same for everybody, Fraser says. Pay attention and modify as needed. For example, you might measure how your blood sugar levels change in response to different foods using a continuous glucose monitor, or by measuring your blood or breath ketones. This can help you figure out what foods affect your blood sugar and ketone levels the most. For instance, a serving of carrots might raise your blood sugar and reduce your ketones more than a serving of tomatoes. Unless you measure it, you will not know, she says.

    Fraser also recommends keeping track of how your sleep changes as you implement a ketogenic diet plus intermittent fasting. Your sleep will be affected if youre either feeling really hungry or really full at bedtime. This might mean, for example, that you need to eat earlier or later, depending on how your sleep is affected.

    For the Fast Diet, the numbers refer to days rather than hours. So for five days, you’re eating a healthy diet, and for two days each week, you’re restricting your calories to 500-600 per day .The two fasting days don’t need to be consecutive, and probably shouldn’t be to improve compliance. There isn’t any scientific research that explains how, why, or whether this form of IF works as well as other forms, but there’s a lot of anecdotal evidence that shows results.

    Keep Up Your Water Intake

    During the non-feeding period, make sure you keep yourself hydrated by drinking a higher amount of water.

    The rule of intermeeting fasting is not extended to water intake.

    Hence, you can drink as much as water you want during the feeding as well as non-feeding period. No restrictions applied here!

    This will prevent fatigue and keep you energetic throughout the day.

    What To Eat While Intermittent Fasting

    During your fasting window, you shouldnt eat anything. During your eating window, enjoy nutrient-dense keto foods like healthy proteins, vegetables, and fats.

    Avoid breaking your fast with processed foods, carb-heavy meals, and dirty keto foods, as these can hinder the health benefits of fasting in the first place.

    Who Should Not Fast

    Wondering how long is it safe to fast? Stop right there. Some people should not fast at all. First and foremost, always talk to your doctor before engaging in the practice of fasting. Its important to discuss any preexisting health conditions you may have that could be affected by reducing your eating window.

    While fasting may provide benefits to some, it is not for everyone.

    If you are pregnant, breastfeeding, elderly, have a history of disordered eating or have a chronic health condition, such as type 2 diabetes or heart disease or high cholesterol, consult with your health provider, and discuss supervised fasting before introducing either IF or longer fasts into your life.

    Are There Benefits To Doing Both Keto And Intermittent Fasting

    Why Does Keto and Intermittent Fasting Work? Dr.Berg

    The idea is that combining the ketogenic diet and intermittent fasting will maximize the time that someone is in ketosis. This could mean more weight loss, less hunger pangs, and more energy.

    “It’s more common for someone to start a ketogenic diet and then layer on intermittent fasting,” says Mancinelli. “They realize, ‘Oh, I can get more bang for my buck and I’m not as hungry anymore. It’s not as common, though, for people who start with intermittent fasting to layer on keto because then it looks like a lot more work to eat very specific foods.”

    While combining the two might boost results, these styles of eating are not for everyone, whether independently or together.

    Pay Attention To Nutrition

    Since you will be fasting for 18 hours a day, dont use it as an excuse to eat junk foods.

    Agreed that you will be able to derive faster results by combining keto diet with intermittent fasting.

    But, that doesnt mean you can eat anything during the 6-hour feeding period.

    You must eat only the foods that are nutritious and keto-friendly. Otherwise, you may develop a deficiency of essential nutrients.

    Also, eating junk foods high in carbs and unhealthy fats may pull you out of ketosis thus negating all the benefits of ketosis.

    Hence, if you want to fast while on the keto diet, do it with dedication and justice to the rules of both the diets. This means:

    • Eating only between the designated periods
    • Increasing your intake of healthy fats
    • Reducing carbohydrate consumption
    • Eating moderate amounts of proteins

    Greater Loss Of Belly Fat

    Fasting may be more effective for reducing belly fat compared to other weight loss practices.

    Aside from physical appearance reasons, heres why thats a big deal.

    The presence of visceral fat, the scientific name for belly fat thats inside your abdomen, may indicate higher inflammation levels in your body. And its associated with a higher risk of heart attack and heart disease, too.

    Fortunately, by fasting, you can reduce your belly fat, which may also reduce the risk of heart problems.
