The difference between calories in and calories out and intermittent fasting for weight loss.

My wife and I have been in the health and wellness industry for almost 4 decades, I am a Wellness Coach/strength and conditioning coach/CMHS, we also competed in building so we have experienced the brutal 12-week diet down before you go on stage, obviously we do have a lot of experience and knowledge, to our surprised when it comes to weight loss we were doing it all wrong all these years. We have used the western weight loss program calories in calories out diet, the problem was it was too hard to keep consistent with watching what you eat writing down how many calories you have eaten that day, is this what I have to do this the rest of my life. Come to find out the calorie in calorie out diet does not work long term, yes you will lose weight at first but the body is not stupide, once it figures out what you are doing it shuts down, your weight loss levels out and 99.9% of you will fail, over the years I have seen some of my past clients that I have helped in the pass to lose weight and in a few months, they have gain their weight back and more. Here is a before and after picture of me, the before picture is me on a western diet at 57 years old the after picture is me at 65 years old on intermittent fasting, what is cool no counting calories, on the days I eat I don’t stress out what I should be eating on my eating window which is 6 to 8 hours of eating, my wife and I have been doing this for about 9 months we choose to eat 95% of or vegetables raw uncooked and toxic free, we get 90% of our protein from vegetables, no red meat, mainly wild caught salmon twice a week, we do homemade kefir, kombucha, and fermented cultured vegetables for our probiotics, digestive enzymes and huge amounts of B vitamins in or kefir, the only over the counter supplement we take is a vegetable protein powder that is cold pressed, basically we no longer spend money on buying supplements, we are now saving a ton of money. We also choose to come off of our brunch fasting that we do daily with a very high nutritional dense meal, some people don’t worry about what they eat, so they will do a western meal like bacon, eggs hash browns, pancakes etc, they are still getting great results, during their eating window they eat whatever they want no counting calories, we choose to eat nutritionally dense foods and besides our body’s feel better after we have eaten.

Science has been showing that calorie in and calorie out does not work, science has been showing intermittent fasting does work short and long term for losing that unwanted belly fat, intermittent fasting has so many health benefits for our bodies, please read on you will see why calorie in and calorie out diets do not work and way intermittent fasting has worked for centuries.

Perhaps one of the most common questions we get is what the difference is between calorie restriction and fasting. Many calorie enthusiasts say that fasting works, but only because it restricts calories. In essence, they are saying that only the average matters, not the frequency. But, of course, the truth is nothing of its kind. So, let’s deal with this thorny problem.

The weather in Death Valley, California should be perfect with a yearly average temperature is 25 Celsius. Yet, most residents would hardly call the temperature idyllic. Summers are scorching hot, and winters are uncomfortably cold.

You can easily drown crossing a river that, on average, is only 2 feet deep. If most of the river is 1 foot deep and one section is 10 feet deep, then you will not safely cross. Jumping off a 1-foot wall 1000 times is far different than jumping off a 1000-foot wall once.

In a week’s weather, there is a huge difference between having 7 grey, drizzling days with 1 inch of rain each and having 6 sunny, gorgeous days with 1 day of heavy thundershowers.

It’s obvious in all these examples that overall averages only tell one part of the tale, and often, understanding frequency is paramount. So why would we assume that reducing 300 calories per day over 1 week is the same as reducing 2100 calories over a single day? The difference between the two is the knife-edge between success and failure.

The portion control strategy of constant caloric reduction is the most common dietary approach recommended by nutritional authorities for both weight loss and type 2 diabetes. Advocates suggest that reducing daily caloric consumption by 500 calories will trigger weight loss of approximately one pound of fat per week.

The American Diabetes Association’s main dietary recommendation suggests to “focus on diet, physical activity, and behavioral strategies to achieve a 500–750 kcal/day energy deficit.” The ‘portion control’ advice to reduce calories has been fairly standard since the 1970s. This reduction is average calories should be spread consistently throughout the day, rather than all at once. Dieticians often counsel patients to eat four, five or six times a day. There are calorie labels on restaurant meals, packaged food, and beverages. There are charts for calorie counting, calorie counting apps, and hundreds of calorie counting books. Even with all this, success is as rare as humility in a grizzly bear.

After all, who hasn’t tried to portion control strategy of weight loss. Does it work? Just about never. Data from the United Kingdom indicate that conventional advice succeeds in 1 in 210 obese men and 1 in 124 obese women (4). That is a failure rate of 99.5%, and that number is even worse for morbid obesity. So, whatever else you may believe, constant caloric reduction does NOT work. This is an empirically proven fact. Worse, it has also been proven in the bitter tears of a million believers.

But why doesn’t it work? For the same reason the contestants of The Biggest Loser could not keep their weight off – metabolic slowdown.
Starvation Mode

The Biggest Loser is a long running American TV reality show that pits obese contestants against one another in a bid to lose the most weight. The weight loss regimen is a calorie-restricted diet calculated to be approximately 70% of their energy requirements, typically 1200-1500 calories per day. This is combined with an intensive exercise regimen typically far in excess of two hours daily.

This is the classic ‘Eat Less, Move More’ approach endorsed by all the nutritional authorities, which is why The Biggest Loser diet scores third on the 2015 USA Today’s ranking of best weight loss diets. And, it does work, in the short term. The average weight loss that season was 127 pounds over 6 months. Does it work long-term? Season two’s contestant Suzanne Mendonca said it best when she stated that there is never a reunion show because “We’re all fat again”.

Their Resting Metabolic Rates (RMR), the energy needed to keep the heart pumping, the lungs breathing, your brain thinking, your kidneys detoxing etc., drops like a piano out of a 20 story building. Over six months, their basal metabolism dropped by an average of 789 calories. Simply stated, they are burning 789 calories less per day every day.

As metabolism drops, weight loss plateaus. Caloric reduction has forced the body has shut down in order to match the lowered caloric intake. Once expenditure drops below intake, you start the even more familiar weight regain. Ba Bam! Weight is regained despite dietary compliance with the caloric restriction and even as your friends and family silently accuse you of cheating on your diet. Goodbye reunion show. Even after six years, the metabolic rate does not recover .

All of this is completely predictable. This metabolic slowdown has been scientifically proven for over 50 years. In the 1950s Dr. Ancel Key’s famous Minnesota Starvation Study placed volunteers on a ‘semi-starvation’ diet of 1500 calories per day. This represented a 30% caloric reduction from their previous diet. In response, their basal metabolic rate dropped about 30%. They felt cold, tired, and hungry. When they resumed their typical diet, all their weight came right back.

Caloric restriction diets only work in the short-term, before basal metabolism falls in response. This is sometimes called ‘starvation mode’. Daily calorie restriction fails because it unerringly put you into metabolic slowdown. It’s a guarantee. Reversing type 2 diabetes relies upon burning off the body’s excess glucose, so the daily calorie-restricted diet will not work.

The secret to long-term weight loss is to maintain your basal metabolism. What doesn’t put you into starvation mode? Actual starvation! Or at least the controlled version, intermittent fasting.

Fasting triggers numerous hormonal adaptations that do NOT happen with simple caloric reduction. Insulin drops precipitously, helping prevent insulin resistance. Noradrenalin rises, keeping metabolism high. Growth hormone rises, maintaining lean mass.

Over four days of continuous fasting, basal metabolism does not drop. Instead, it increased by 12%. Neither did exercise capacity, as measured by the VO2, decrease, but is instead maintained. In another study, twenty-two days of alternate daily fasting also does not result in any decrease in RMR.

Why does this happen? Imagine we are cavemen. It’s winter and food is scarce. If our bodies go into ‘starvation mode’, then we would become lethargic, with no energy to go out and find food. Each day the situation gets worse and eventually we die. Nice. The human species would have become extinct long ago if our bodies slow down each time we didn’t eat for a few hours.

No, instead, during fasting, the body opens up its ample supply of stored food – body fat! Yeah! Basal metabolism stays high, and instead we change fuel sources from food, to stored food (or body fat). Now we have enough energy to go out and hunt some woolly mammoth.

During fasting, we first burn glycogen stored in the liver. When that is finished, we use body fat. Oh, hey, good news – there’s plenty of fat stored here. Burn, baby burn. Since there is plenty of fuel, there is no reason for basal metabolism to drop. And that’s the difference between long-term weight loss, and a lifetime of despair. That’s the knife edge between success and failure.

Fasting is effective where simple caloric reduction is not. What is the difference? Obesity is a hormonal, not a caloric imbalance. Fasting provides beneficial hormonal changes that happen during fasting are entirely prevented by the constant intake of food. It is the intermittency of the fasting that makes it so much more effective.

Intermittent Fasting vs Calorie Restriction

The beneficial hormonal adaptations that occur during fasting are completely different from simple calorie restriction. The reduction of insulin and insulin resistance in intermittent fasting plays a key role.

The phenomenon of resistance depends not only upon hyperinsulinemia, but also upon the persistence of those elevated levels. The intermittent nature of fasting helps to prevent the development of insulin resistance. Keeping insulin levels low for extended periods of time prevents the resistance.

Studies have directly compared daily caloric restriction with intermittent fasting, while keeping weekly calorie intake similar. A 30% fat, Mediterranean style diet with constant daily caloric restriction was compared to the same diet with severe restriction of calories on two days of the week.

Over six months, weight and body fat loss did not differ. But there were important hormonal differences between the two strategies. Insulin levels, the key driver of insulin resistance and obesity in the longer term, was initially reduced on a calorie restriction but soon plateaued. However, during intermittent fasting, insulin levels continued to drop significantly. This leads to improved insulin sensitivity with fasting only, despite similar total caloric intake. Since type 2 diabetes is a disease of hyperinsulinemia and insulin resistance, the intermittent fasting strategy will succeed where caloric restriction will not. It is the intermittency of the diet that makes it effective.

Recently, a second trial directly compared zero-calorie alternate-day fasting and daily caloric restriction in obese adults. The Caloric Reduction as Primary (CRaP) strategy was designed to subtract 400 calories per day from the estimated energy requirements of participants.

The ADF group ate normally on eating days, but ate zero calories every other day. The study lasted 24 weeks.

What were the conclusions? First, the most important conclusion was that this was a safe and effective therapy that anybody could reasonably follow. In terms of weight lost, fasting did better, but only marginally. This is consistent with most studies, where, in the short term, any decent diet produces weight loss. However, the devil is in the details. The truncal fat loss, which reflects the more dangerous visceral fat,was almost twice as good with fasting as opposed to CRaP. In fat mass %, there is almost 6 times (!) the amount of loss of fat using fasting

The other big concern is that fasting will ‘burn muscle’. Some opponents claim (without any evidence) that you lost 1/4 pound of muscle for every single day of fasting you do. Considering I fast at least 2 days a week, and have done so for years, I estimate my muscle percentage should be just about 0%, and I shouldn’t even have enough muscle to type these words. Funny how that didn’t happen. But anyway, what happened in that study? The CRaP group lost statistically significant amounts of lean mass, but not the IF group. Yes, there is LESS lean muscle loss. Maybe it has to do with all the growth hormone and nor adrenalin being pumped out.

Lean mass % increased by 2.2% with fasting and only 0.5% with CRaP. In other words, fasting is 4 times better at preserving lean mass. So much of that old ‘fasting burns the muscle’.

What happens to basal metabolism? that’s what determines long term success. If you look at the change in Resting Metabolic Rate (RMR). Using CRaP, basal metabolism dropped by 76 calories per day. Using fasting, it only dropped 29 calories per day (which is not statistically significant compared to baseline). In other words, daily caloric reduction causes almost 2 1/2 times as much metabolic slowdown as fasting! So much for that old ‘Fasting puts you into starvation mode’.

Fasting has been used throughout human history as a tremendously effective method of controlling obesity. By contrast, the portion control strategy of daily caloric restriction has only been recommended for the last 50 years with stunning failure. Yet, conventional advice to reduce a few calories every day persists and fasting is continually belittled as an outdated, dangerous practice akin to blood-letting and voodoo. The study reports that “Importantly, ADF was not associated with an increased risk for weight regain”. Holy S***. That’s the Holy Grail, Man! The whole problem is obesity and The Biggest Loser is WEIGHT REGAIN, not initial weight loss.

Weight regain differed during fasting vs CRaP. The fasting group tended to regain lean mass and continue to lose fat, while CRaP group gained both fat and lean mass. Part of the issue was that the fasting group reported that they often continued to fast even after the study was done. Of course! It is easier than they though, with better results. Only an idiot would stop. One of the very fascinating things is that ghrelin (the hunger hormone) goes up with CRaP but does NOT during fasting. We’ve known forever that dieting makes you hungrier. It’s not a matter of willpower – it’s a hormonal fact of life – the ghrelin goes up and you are hungrier. However, fasting does not increase hunger. Fascinating. No wonder it’s easier to keep the weight off! You’re less hungry.

Calorie restriction diets ignore the biological principle of homeostasis – the body’s ability to adapt to changing environments. Your eyes adjust whether you are in a dark room or bright sunlight. Your ears adjust if you are in a loud airport or a quiet house.
The same applies to weight loss. Your body adapts to a constant diet by slowing metabolism. Successful dieting requires an intermittent strategy, not a constant one. Restricting some foods all the time (portion control) differs from restricting all foods someof the time (intermittent fasting). This is the crucial difference between failure and success.

So here’s your choices:

1.Caloric Reduction as Primary: less weight loss (bad), more lean mass loss (bad), less visceral fat loss (bad), harder to keep weight off (bad), hungrier (bad), higher insulin (bad), more insulin resistance (bad), perfect track record over 50 years unblemished by success (bad)

2.Intermittent Fasting: More weight loss, more lean mass gain, more visceral fat loss, less hunger, been used throughout human history, lower insulin, less insulin resistance.

Almost every medical society, doctor, dietician, and mainstream media will tell you to use choice #1. I prefer to tell people to take choice #2.

A very important tip, before you start your intermittent fasting ( intermittent fasting is not a ketogenic diet nor is it a diet it is a lifestyle) you need to change the type of water you and your family drinks, think about this your body is 75% water most of the public are drinking bottle water tap water and those so called alkaline waters you buy at health foods store, the media social media has been telling you guys for years that those water are full of toxic chemicals that are slowly poisoning your family and can cause cancer, and yet the public look the other way check out this short video that will show the truth about the water you are drinking http://www.demo.drinknatureswater.com if it makes since msg we will let you try electrolyzed reduced water for free with no obligation for a couple weeks.
