When the weight loss comes back: unsustainable versus permanent fat loss

The biggest fallacy in weight loss is the assumption that once you lose weight you will keep it off for ever. This is what many of us dream will be the case, which leads us to quick-fix solutions like crash diets and HIIT, but in reality for the majority it just doesn’t work. Why is that? What are we doing wrong? And what should we be doing to fit into our skinny jeans and little black dresses?

Unsustainable weight loss

Fat loss transformation of a woman
Research has shown that if you lose weight too quickly, it is likely that you will gain it right back and MORE!

The American game show, America’s Biggest Loser, is famous for extreme dieting, hard core exercise and generally braking the balls of its contestants in a very short space of time. They show us before pictures, 12 week later pictures but what they don’t show us is 12 months or 5 years later pictures. As this 2017 study1 says, “It is estimated that only about 20% of individuals who experience significant weight loss are able to maintain their lost weight2. Data from participants in the Biggest Loser Television program demonstrate the difficulty in maintaining lost weight over time. The average weight loss of the 14 participants during the 30-week intervention was 58 kg, but six years later, nearly all of the contestants had regained the weight they had lost3.”

 

“…nearly all of the contestants had regained the weight they had lost.”

 

Many of those people put on even more weight than they lost in the first place as their willpower plummeted and their appetite came back with a vengeance. Ryan Benson, for example, who won the competition in 2005, was 300 lbs (136kgs), dropped to 175 and then before you know it was back above he old level up to 325 lbs!

 

Furthermore in a 2015 UK study that looked at 76,704 obese men and 99,791 obese women they found that over a 9 year period only 0.5% of the men and 0.8% actually lost weight. The study concluded, depressingly, "The probability of attaining normal weight or maintaining weight loss is low. Obesity treatment frameworks grounded in community-based weight management programs may be ineffective."

 

"...over a 9 year period only 0.5% of the men

and 0.8% of the women actually lost weight."

 

So let’s now take a look at some of the common mistakes of unsustainable weight loss and then later on what we can do about it instead.

Cutting out a macronutrient (fat, protein, carbohydrates)

Problem

The respective macronutrients (carbs, proteins and fats) that are essential for permanent weight loss
If you want to lose weight and keep it off for good then, it is important not to cut out any of the essential macronutrients.

One of the most common ways to lose weight is to embark on a diet that removes an entire macronutrient food group be it either fat, carbohydrates or protein. Most of the modern English speaking world has been on a low fat, high processed carbohydrate diet since Ancel Key’s famously manipulated “7 countries study” which he started in the 1950s. This has been a disastrous 60 year experiment with record numbers of people with sugar related illnesses such as diabetes, cancers, cardiovascular and neurodegenerative diseases.

 

And more recently many people have started to swing the other way to a low carb, high fat, diet. This certainly works for some people as they are now more likely to be eating closer to their metabolic type but it doesn’t work for everyone. And in the long term low carb diets can start to damage the mucosal lining of the gastrointestinal tract, create bacteria gut dysbiosis, cause hypothyroidism and fry your adrenals.

 

And then we have a whole group of people eschewing animal protein completely which can lead to osteoporosis, mental challenges such as depression, irrational anger and obsessive compulsive disorders (see this post on how our diet affects our mental and emotional health), higher risk of bone fractures and anemia.

 

Solution

The key to long term sustainable weight loss is in eating right for your Primal Pattern Diet TypeTM. What does that mean? It means eating your macronutrients in the proportions that are most appropriate for you, not your neighbour's, not your personal trainer's, not the latest fad diet but you! And then sensibly and intuitively adjusting for variables such as weather, temperature, seasons, exercise, menstruation and pregnancy.

Calorie restriction

Problem

They key to long-term weight loss isn't restricting calories.
The key to long-term weight and fat loss is not through calorie restriction.

Short term it works, eat less, burn fat, lose weight. So it's very popular. But in the long term it doesn’t work for the following reasons:

 

1. Willpower

Eating less than your body needs requires willpower. And you have a finite amount of willpower that gets recharged every time you go to sleep. Over time your willpower bucket gets drained and the desire to overeat to compensate for the period that you under-ate gets stronger and stronger until finally you cross the Rubicon and calorie consumption increases to match your reset hunger levels again and the weight comes back.

 

2. Grehlin

The less you eat the more the pituitary gland in the brain will instruct the body to secrete Grehlin to ramp up your appetite. Your body is literally fighting you on the inside. An internal pitched battle eschews between your conscious desires (lose weight) and your subconscious needs (maintain fat reserves).

 

3. Metabolism

Your metabolism, controlled by your thyroid, literally decides how much energy you burn. By increasing your metabolism, by just a little you will burn excess calories. But if your body, for whatever reasons, thinks that you’re not getting enough quality fuel on board it will down regulate your metabolism which means you’ll burn fewer calories. What researchers found after studying the contestants of the Biggest Loser gameshow was that even as the years went by the contestants’ metabolisms did not recover. They became even slower, and the pounds kept piling on. It was as if their bodies were intensifying their effort to pull the contestants back to their original weight. Stephan Guyenet, the PHD obesity specialist researcher calls this the "fat set point".

 

4. Leptin

Leptin is a hormone secreted by your fat cells and your body wants to preserve those valuable stores of fuel for the winter. Your body will defend this “fat set point” so as it notices the amount of leptin in your blood stream decreasing it sends a signal to your brain to increase hunger and increase the fat back to where your body thinks it needs to be – which is usually not where you want it to be!

 

5. Less connected

If you follow people over the long term, dieters are more likely than non-dieters to end up gaining weight over the next two to 15 years after the calorie restricting diet they’ve been on. As they increasingly intellectualise their eating habits as opposed to eating instinctively they are more prone to eating junk food, overeating, eating emotionally and generally not listening to their body’s needs.

Solution

One of the healthiest and best ways to shed pounds and keep them off for good is to practice intuitive eating.

The solution is simple, don’t diet. But that doesn’t mean eat like a pig! It means focusing on wholesome healthy eating, embracing organic fruits and veggies, wild fish, pastured meats and eschewing processed foods, sugar, commercial dairy, commercial soy, table salt, flour and vegetable oils. And then you will slowly revert to your body’s more natural set point and stay there.

 

One of the most commonly overlooked satiety symbols that your body needs to decide that it’s full is the amount of vitamins and minerals absorbed and NOT how much you filled your stomach up. You wonder why it is that you ate that large Big Mac, fries and milk shake and 1 hour later you’re still hungry? It’s because it’s devoid of a full compliment of minerals, vitamins and phytonutrients. Yes, you stretched your stomach but you didn’t nourish your body. The answer here is the complete opposite of what the diet dictocrats would tell you. Eat high quality nutrient dense foods including wild fish, pastured meats, egg yolks, organs, high quality dairy, foods high (yes high) in cholesterol, shellfish, grass fed butter, bone broths and lacto-fermented veggies.

Cardio

Problem

If permanent weight loss is your goal then focusing your fitness routine on running, or other forms of cardio, isn’t the best way to achieve long lasting results.
If permanent weight loss is your goal then focusing your fitness routine on running, or other forms of cardio, isn’t the best way to achieve long lasting results.

So looking at this problem from a physical exercise perspective, we start off with endurance exercises such as running, marathoning, spinning, body pump and gym classes that raise your heart rate to quite a high level for 60 minutes or more. Endurance sports rarely work for people that are already overweight or do not have a great diet to begin with. When you burn a bunch of calories in the form of some kind of intensive, sweaty exercise regime your body decides to ramp up your hunger hormone, ghrelin, in response to the exercise. Yes you may finish your session and have a salad but later on that night when grehlin is through the roof and willpower is floundering on the floor your body fights back and reaches for whatever high carb snack it can find in the house!

 

For those that are lean and do run a lot the main problem stems from 2 angles. The first is that a lot of cardio exercise causes the body to cannibalise the muscles (type IIa and IIb fibers responsible for strength and power) in order to keep the total body weight low. And strength directly correlates to insulin sensitivity and longevity so we now have a far less forgiving metabolism if we do deviate from a strict dietary path. Secondly, as you become more efficient and adapted to the cardiovascular exercise the body increasingly requires more and more time spent in the high heart rate cardio zone in order to burn the same amount of calories.

 

To be honest you’ll know if you fall into this category pretty easily. Did you stop doing any exercise for a week or two and suddenly start putting on weight? If so then that ain’t sustainable!

Solution

The solution for most people, and especially those that don’t like endurance sports, is to find something that you enjoy that you can keep up long term – preferably something that involves strength work. Muscles are metabolically active 24/7 requiring calories to fuel them even in your sleep. Also the more muscle mass you have the more glycogen stores and the more insulin sensitive you are – all factors that contribute to keeping the fat off. For many people that don’t enjoy cardio, they often find that they actually really like strength training – particularly if done in a safe, fun and exclusive environment. And just to be clear strength training is not body building which is something completely different!

HIIT

Problem

The advantage with HIIT is you'll burn more calories than normal for the rest of the day. The disadvantage is that it’s exceedingly stressful on the body.
The advantage with HIIT is you'll burn more calories than normal for the rest of the day. The disadvantage is that it’s exceedingly stressful on the body.

High intensity interval training is 20 to 30 mins of hard core exercises that max out your heart rate and have you dripping buckets. The advantage with this is that it boosts your metabolism so you burn more calories than normal for the rest of the day well after you’ve stopped exercising. The disadvantage is that it’s exceedingly stressful on the body which basically thinks it’s running away from a lion for 30 minutes straight. Digestion is shut down, the immune system is shut down, fertility is shut down, in fact every non essential function is shut down apart from pumping blood to your arms and legs to complete the exercise regime. If you are not primed to handle this stress, (and most working professionals are not), then your body goes into “fat storage mode”. So in the short term you burn a few extra calories but in the long term your metabolic rate decreases as your body thinks you’re in a war zone and it’s best to conserve fat.

 

Likewise,  unscrupulous gym owners will often sell you the before and after pictures solution that promises flat stomachs, ripped abs and the body of your dreams as evidenced by all these people. What they don’t tell you is two things. (1) That this is only a small % of their total number of clients and (2) They don’t show you the 12 month later pictures when all the weight has come back on! If a regime requires you to work out hard 3 to 4 times a week the chance of sustaining that for most people over the long term is highly unlikely due to time, expense and motivation commitments.

Solution

The solution is to start off with a programme that you think you could commit to for life. If that’s 4 times a week with a HIIT session sandwiched in between then great! But if it’s not then shoot for something realistic. Something that means as soon as you go on holiday for 2 weeks you won’t come back and find yourself completely unmotivated to get started again. Make it fun and manageable for long term success.

Wrapping up

So there you have it. The common problems associated with short term unsustainable weight loss and their associated solutions. The one thing we didn't discuss was water fasting (consuming nothing but water over periods of 24 hours to 30 days) which does reset the body's "fat set point" without lowering your basal metabolic rate. However this is a lengthy topic that will require a blog post all of its own. So in summary we need to apply a huge dose of common sense to what we’re doing with regards to our weight management goals. Plan for the long term and you’ll get the body you want in the medium term because the short term will be over before you know it!

    Totally agree with all the above. Diets mean restricting something the body craves and that basically can't last. It must be be a sustainable lifestyle that you develop, gradually replacing bad habits with good. It means overcoming the powerful subconscious brain which runs our habitual life. Become mindful that food is nutrition and not entertainment or simple filling a hole. With every bite you have the opportunity to provide your body with quality nutrition with disease fighting properties that are known to strengthen the immune system and reduce chronic disease and cancer.

    Thanks for your support Tim. Yes these are super ways to help people to lose weight and reverse chronic disease without resorting to extreme measures and using a whole bunch of willpower. Unfortunately there is so much noise and clutter from the media sometimes it's hard for people to know what to do so hopefully we can provide a glimmer of light!
