| Why Does a Low-Carb Diet Stop Working? |
However, for many dieters, counting carbohydrates and
staying within a certain daily allotment isn’t enough to achieve success.
In my own case, the problem with not losing weight on a low-carb diet can be traced to a variety of issues:
But weight-loss problems are never the same for everyone. In general, the closer you get to goal weight, the more important calorie counting, fat intake, and portion control becomes. However, for many individuals, the amount of weight you’ve already lost and the length of time you’ve been low carbing plays just as large a role in the final outcome. Maybe, even more.
In my own case, the problem with not losing weight on a low-carb diet can be traced to a variety of issues:
- hidden food sensitivities
- celiac disease
- leaky gut syndrome
- endocrine disruptors
- fat malabsorption
- probably excessive ASP
- and who knows what else
But weight-loss problems are never the same for everyone. In general, the closer you get to goal weight, the more important calorie counting, fat intake, and portion control becomes. However, for many individuals, the amount of weight you’ve already lost and the length of time you’ve been low carbing plays just as large a role in the final outcome. Maybe, even more.
Misunderstandings Regarding Fat Storage
Many low-carb dieters believe you cannot store dietary fat without
high insulin levels. They believe that low basal insulin and avoiding all
insulin spikes always creates a favorable environment for fatty acid mobilization
and utilization. If that were true, it would make calorie counting obsolete. However, fat storage and
fat mobilization are accomplished quite differently than the method that most low
carbers believe in.
When you eat dietary fats, Acylation Stimulating Protein, or
ASP, rises significantly. This rise does not occur from glucose. Elevated ASP
levels are independent of insulin and cause all dietary fats not immediately
needed for fuel to be stored in your fat cells. This is opposite to the ongoing
belief within the low-carb community that says insulin stays unchanged when you
eat fats (therefore high fat is good) and only rises when glucose spikes (so
eating carbs is bad). They conclude that low insulin therefore means easy fat mobilization.
However, later on, when the body needs fuel, Hormone Sensitive Lipase,
or HSL, is stimulated. HSL breaks triglyceride down into fatty acids. Fat
storage is not stagnant. It’s more like a constant river that runs in and out
of the fat cell. Fat cells are not actually storage depots. The flux of ASP fat
storage and HSL release can get clogged. When that happens, more dietary fat
enters the fat cell than leaves. That is what actually causes overweight and
obesity: the inability to use stored body fat for fuel.
How Dietary Fats Affect a Low Carb Diet Plan
Most people following a low-carb diet plan do not find value
in counting calories. Others believe that eating more dietary fat will provide better
weight-loss success. However, if dietary fat provides more fuel than is needed to
achieve effective weight loss, the body will store more fat than it can
mobilize. HSL only releases enough fatty acids to meet your daily metabolic
needs. It doesn’t release extra just because you’ve upped your dietary fats.

If you fall into the obese category, your ASP fasting basal
levels are 58 to 400 percent higher than ASP basal levels found in those who
are not. Higher circulating ASP interferes with HSL stimulation and therefore fat
mobilization. Regardless of low insulin levels achieved by following a low-carb
diet, when ASP levels are consistently elevated, stored body fat cannot be broken
down into fatty acids for fuel. When such individuals raise the fat content of
their diet, the result is easy weight gain rather than fat loss.
Why Portion Control and Counting Calories Matter
In the beginning of a low-carb diet, carbohydrate levels are
low. Depending upon how much you weigh and how much you need to lose, most
people initially find they can eat high amounts of dietary fat without having
to focus on portion control or calories. You can experience effective weight
loss rather easily because your energy needs are high.
For example, when I first started low carbing in 2007, I
weighed 256-1/2 pounds. Even though I’m only 5-foot tall, at that weight, maintenance
for me was over 3,000 calories a day! Since most people are much taller than I
am, maintenance calories in the beginning of your journey will be quite high.
This enables a dieter to adjust to the changes that a low-carb diet demands.
At some point, as body fat is lost and body fuel needs
change, if a low-carb dieter continues eating high-calorie foods, energy input
catches up with and balances energy output resulting in a long, lengthy stall. If
you’re still in the obese category as I am, that also means higher circulating
ASP. Plus, depending upon how long it has taken to reach your current level of
health, your metabolic rate may also have dropped since we’re utilizing and
optimizing the body’s starvation pathway.
What most stalled low-carb dieters fail to consider is that
their new smaller body now needs less fuel. While maintenance for me in 2007 (working
in a boys’ home) was 3,000 calories per day, today, (writing online) it’s less
than 1800! Plus, my body is going to extensive measures to replace the body fat
it’s lost. While that doesn’t happen to everyone, it has happened to me.
Weight-Loss Success Sometimes Requires Less Dietary Fat
The purpose of all diet plans is to help you learn healthy
eating habits. A low-carb diet plan can be an effective way to focus on and
zero in on nutrient-dense foods. It can help to get you off of the processed carby
junk and onto a more whole-foods diet. However, a low-carb diet doesn’t
automatically translate into long-term, effective weight loss. Eventually, many
of us come to realize that a 16-ounce porterhouse steak is not everyday life. It’s
an exception to the rule.

That’s why it’s essential to customize your low-carb diet plan to fit your desires, health needs, lifestyle, food sensitivities, and
metabolic issues. There is not a single low-carb program that works for
everyone. Low-carb diets as written are wonderful starting points, but that’s
all they are – starting points. They give you a place to start from. The Atkins
Diet was never designed to be a one-size-fits-all diet plan that the low-carb
community has turned it into today.
In fact, Dr. Atkins himself has said that some individuals
do better on a low-fat diet. His nurse has said that sometimes calories do have
to be addressed because the diet works best if you eat only as much as you need
to avoid the discomfort of hunger. Now, that’s very different then the high-fat
mindset being preached today.
Personal Effects of Eating High-Fat Low-Carb
The bottom line is that some people do best on a high-fat
low-carb diet. Some people do best on a moderate-fat diet, and some people do
best on a lower fat diet, but that doesn’t mean that if you need to eat lower
fat you’re doing something wrong. It doesn’t mean that you need to change what works
best for you to fit someone else’s ideal. It’s fantastic when you find something that
works for you. It’s fantastic that so many people want to share what they’ve
discovered about themselves.
But let’s not forget that these discoveries are personal
discoveries. For me, I cannot eat a high-fat diet. I have never been able to
eat a high-fat diet, even when I was doing Atkins in 2007. I did do some recent experiments with Nutritional Ketosis and high-fat eating because I was hoping
that my fat issues might have actually been about eating too much protein, or
were tied into my intestinal inflammation problems, but that hasn’t turned out
to be the case.
I’ve come to a few realizations about myself that I wasn’t
aware of before. Because I adopted suggestions made by others, I’ve paid a high
price for those experiments. I’ve paid a high price for listening to and
embracing the personal discoveries of others. My weight is up. My cholesterol
numbers came back very bad two weeks ago, as did my A1c. Both were excellent
when I was eating low-fat low-carb, so the only variable that has changed in my
life was moving to a high-fat diet.
In addition, my overall health has taken a dump. The vertigo
is almost as severe as it was when I lived in California and has not corrected
itself even though I stopped eating a high-fat diet last week. My neuropathy and
arthritis are back, even though both were in remission before I raised my fat
intake. I am really, really tired, but that’s not surprising given my high
triglycerides right now.
The point is simple. A low-carb high-fat diet isn’t magic
for everyone. Some of us need to eat a low-fat low-carb diet. Some of us need
to eat a low-fat, low-carb, very low-calorie diet in order to achieve weight-loss
success. That’s just what is. The question I now have to answer for myself is
this:
Is it worth the price?
I’m not sure that it is.
