Pay Attention To Your Body

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

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.

Keto And Intermittent Fasting Diets May Not Work

Keto and intermittent fasting diets are popular however, scientists have yet to identify the genes or proteins that enable the diets to work and whether they work.

The metabolic switch between sugar and fat its amazing that we dont understand it yet. But if we do, we can tell you if keto is right for you, said UCR biochemist Sarah Radi.

A $2m grant from the National Institutes of Health will allow Radi and cell biology professor Frances Sladek to investigate the metabolic switch, allowing the scientists to understand how it might work.

The researchers found that the key is likely a protein called HNF4, found at high levels in the liver. It is a transcriptive factor that converts DNA into RNA that subsequently makes new proteins, and it comes in two forms, P1 or P2.

The UCR-led team investigated P2 as a pro-cancer protein. However, they did not find the link to cancer, but they did notice mice with high levels of P2 in their livers also had different genes for metabolism.

Furthermore, they uncovered that P2 shows in greater quantity later in the day, which could explain why mice didnt gain nearly as much weight if the eating times were restricted even if the mice ate too much.

Radi suspected that an energy-sensing enzyme could cause the switch between P1 and P2, enabling the process of burning fat for energy.

Intermittent Fasting Why Meal Timing Matters

Simply put, intermittent fasting is the dietary strategy of restricting your food consumption to a specific window of time. For example, one of the most common intermittent fasting approaches is fasting during an 18-hour window of time and eating during the 6-hour window of time that is left in the day.

Lets say your last meal was at 6 pm last night and you ate nothing else after that. To implement an intermittent fast, simply restrict eating until 12 pm the next afternoon . To do this every day, only eat between 12 pm and 6 pm and fast for the remainder of the day.

There are many different variations of intermittent fasting as well. Dr. Dom DAgostino, a well-known ketogenic diet researcher, suggests doing a longer intermittent fast for 3 days, 3 times a year. This means not eating for 3 days, and eating normally until the next fast.

Another way to try fasting for yourself is by incorporating intermittent fasts of 16 or more hours per day into your lifestyle. This is a much more accessible strategy that allows you to experience many of the benefits of taking a short break from calories.

Despite the simplicity of this concept, it may not be readily apparent how beneficial intermittent fasting can be for you, especially if you are already benefiting from the ketogenic diet.

My Weight Loss Results

I experienced effortless weight loss during the experiment. The weight loss I experienced was much quicker than with only intermittent fasting. My average weight loss with intermittent fasting only was about 2-3 lbs a month. After the initial water loss , I lost two more pounds. Losing 2 lbs over less than 2 weeks is a lot for me! Since weight loss was not my focus, I was eating a lot and snacking between meals. This made me wonder how I would maintain my weight if I decided to keep up the keto diet long term. Now, that I am back to eating carbs until the beginning of my next cycle, I can say that I have not gained any of the weight back after 5 days. I assume the appetite suppressing effects of increased ketones are still at play.

Leangains Protocol Or The 16/8 Method

With the Leangains version of IF, you eat during an 8-hour window and fast for 16 hours. This method can fudge a little bit in either direction, so 14/10 or 15/9 also works.During your eating window, you can either eat two or three meals. Ideally, youre not snacking for the whole window. This method can be pretty easy to follow just by having an early dinner and a later breakfast. Or, if youre able to skip breakfast, that works too. It’s ok to drink water, black coffee, herbal tea, or even bone broth in some cases during the fasting window.Women should only fast for 14 to 15 hours at a time, due to their more complicated hormonal makeup. While there’s a lot of good research on the efficacy of intermittent fasting, much of it is done with male subjects , so it’s important to take sex into account when planning your diet. This isn’t to say that fasting doesn’t’ work for women, it’s just to say that women have more to consider, especially premenopausal women. There’s preliminary evidence that menopausal and postmenopausal women may find more success with both IF and keto, due to their lower levels of estrogen.

Intermittent Fasting And Mental Health Benefits

It seems intermittent fasting can help your mind as well as your body. Fasting has been shown to help improve your memory, reduce oxidative stress, and preserve learning function. Some researchers believe that because humans went thousands of years where food was not readily available, they adapted to function at a high-level while in a food-deprived state.

There are several theories as to how fasting helps improve cognitive function. Some scientists believe that because your cells are under mild stress while fasting, it helps improve their function. Your cells adapt to this stress by enhancing their own ability to cope, which helps you focus more intently.

This is similar to the stress your body undergoes when you hit the gym. While exercising, that is a form of stress your body endures. As long as you give your body enough time to recover afterward, it will do your body good. The same applies for intermittent fasting as long as continue to alternate between regular eating habits and fasting, it will continue to benefit you.

Finally, when you go long periods without food, it causes your body to release ketones into your body. This has been shown to improve memory and learning ability, as well as slow down diseases in the brain.

To those who find calorie restriction or constant dieting stressful, intermittent fasting is an appealing alternative. Some studies show that patients actually preferred fasting to constant calorie restriction[*

Do Keto First Fasting Second

How to do Intermittent Fasting for Serious Weight Loss Dr.Berg

The goal of the ketogenic diet is to lower carb intake to 20-50 grams per day, about a quarter of what the average American eats. Low carb intake helps the body make ketones, which diminish hunger. Fraser says its easier to get used to the ketogenic diet before adding on intermittent fasting. If you do keto first, you avoid that sensation of hunger as you decrease your eating window.

Lisa Amorao, an open water swimmer and LIFE apps user who has been following a ketogenic diet since 2016, says the ketogenic diet helped her become aware of processed carbs. Once she eliminated them she stopped feeling hangry. This meant that eating was no longer an emergency and I could take the time to shop and prepare food that I actually wanted to eat, she says.

Due to ketones keeping you full longer, the ketogenic diet also makes longer fasts more doable. LIFE apps user Elaine Pomerleau has been doing intermittent fasting together with a ketogenic diet for the past year, but she started following a ketogenic diet first. A few weeks later she added intermittent fasting, progressively increasing her fasting hours until she was able to do a 5-day fast. I have lost 85 pounds, no more diabetes, no more fatty liver, and almost no polyarthritis, she says.

Combining Keto & Intermittent Fasting: Benefits + Challenges

Intermittent Fasting &  Ketogenic Diet

Although they may seem different on the surface, Keto and IF share many similarities. They both encourage the body into a Ketogenic state, and have the potential to increase fat burning. Theres also a lot of crossover between the potential wellness benefits, from heart health to insulin sensitivity.

You may be wondering whether it’s safe and effective to combine the two — extending your fasting window, and consuming a high-fat diet during your eating window.

The good news is that because both diets work via similar underlying mechanisms, they have the potential to complement each other. Keto and IF act synergistically towards the same end goal – making the body more adept at burning fat as a fuel. You might also find that the common challenges of each diet are canceled out when you combine them together:

  • Restricting food intake through IF may make it easier to get into and stay in ketosis, as this kick-starts the depletion of carbohydrate levels.
  • A Ketogenic diet may make intermittent fasting feel easier as your body becomes more fat-adapted, and you feel more satiated from consuming higher-fat foods.
  • If youre fairly new to Keto, you may find that IF helps you stick to the diet, as you have fewer meals to think about and prep.

That being said, there are some potential drawbacks to be aware of:

One Meal A Day Isnt Backed By Evidence And Can Make It Harder To Get Daily Nutrients

The specific type of intermittent fasting promoted in speed keto is one meal a day eating schedule, sometimes abbreviated to OMAD. It can certainly help with weight loss, according to Limansky, since eating less often will likely cause you to consume fewer calories overall and, keto or otherwise, losing weight always requires a calorie deficit.

But theres no evidence that its any better than other, less extreme styles of intermittent fasting, according to Robin Foroutan, a registered dietitian nutritionist and representative for the Academy of Nutrition and Dietetics. And it requires some planning to get all your daily nutrients and calories in one sitting that single meal has to be high-quality and well balanced, or youll be missing out on important dietary components like vitamins, minerals, and fiber.

That means you might be following a plan that requires much more effort without extra pay-off in terms of health benefits, Foroutan told Insider. It is probably not that easy to get all the nutrients youll need for the day in that one meal without over stuffing yourself, which isnt great for digestion and absorption.

Ketosis With Intermittent Fasting Step

You will need to think of the right schedule for your lifestyle and experiment to see what works best for you.

Kickstart Ketosis

If you are just getting started with intermittent fasting, I suggest you start with the fasting mimicking diet or the keto diet. If you choose the keto diet, you may only need a few days as well. You will most likely get the keto flu and when you feel better, you will be in ketosis.

If you choose the fasting mimicking diet, you may not notice a difference the first time around. Keep experimenting with intermittent fasting the rest of the month and you will notice that when you do the fasting mimicking diet again , it will be a lot easier. You will achieve ketosis.

Choose Your Intermittent Fasting Schedule

For some people, it takes more than 16 hours to get in ketosis using intermittent fasting. Testing could be helpful. I use this ketone monitor :

You are in ketosis when your reading is anything above 0.5 mmol/L. With time, you will know the difference without even measuring.

Start gradually, fast from 8 pm to noon the next day for 2-3 weeks, and see if you notice a difference. If you dont, increase your fasting window or try a different intermittent fasting method that doesnt require daily fasting like the Eat-Stop-Eat Diet.
