Taubes doesn't know what he talks about and what he did with this book is not serious research but cheesy cherry picking.
Taubes claims that carbs/glucose are recognized as the sole responsable
for insulin secretion. The fact that he doesn't seem to know or understand that as soon as we consume 1 gram of protein our insulin goes up because the role of insulin is also to metabolize proteins makes Taubes the most ignorant writer on nutrition ever.
What Taubes claims about insulin increasing fat storage is not only scientifically undemonstrable but also completely illogical and counterproductive to body survival.
There's a reason why the body stores excess calories as fat
and burn that fat where there's not enough dietary calories.
The reason is that this system is perfect and precise and allows
the best survival in whatever situation.
If really lowering one macronutrients (carbohydrates) would
result in less fat storage during excessive caloric consumption and more fat loss during defective caloric consumption, it would be the biggest metabolical flaw of the body and we would not be alive today.
Maybe it doesn't seem clear to our sedentary and glutton generation but the ability of the body to store excess calories as fat is a key of our survival. So is the ability to burn body fat at a steady rate, neither slower or faster occording to how many carbs one eats.
Have you ever wondered why insulin is high after eating proteins
or carbohydrates? Insulin is high because it is supposed to send
the amino acids and the glucose molecules in the cells.
Insulin is not a fat storage hormone !
Insulin is a transporter which either transports nutrients to the cells
or either transport fats to the adipocytes. It can't do both at the same time.
When there are amino acids and/or glucose in the blood insulin is secreted to transport these nutrients to the cells. Once the job is done insulin goes back to normal levels.
If the cells are full (hence an excess of calories) insulin tranports the molecules to the adipocytes where fat is stored.
It's absolutely ignorant and unscientific to believe that insulin can
trigger fat storage per se, even if there's no excess of calories and
that insulin means high storage.
Maybe you don't know that insulin also stores proteins as fat if there's an excess of calories. And maybe you don't know that a protein called ASP store dietary fat as fat if there's an excess of calories.
Dietary fat is glycerol and fatty acids and body fat is glycerol and fatty acid. In other words dietary fat remains the most easy to store as fat for the body and even if you eat nothing but butter, if you eat an excess of calories from butter, you gain weight, period.
The convertion of carbohydrates to fat is a very weak and irrelevant pathway. Under normal condition carbohydrates are never coverted to fat.
Something is needed to trigger such pathway and to increase the efficiency of carbs to fat conversion. This something is "too many calories"
But even if someone accepted the unscientific belief that insulin
triggers fat storage even when calories are normal or low, the whole
idea still would not make any sense.
If you eat carbs and the body instead of burning those calories store them as fat where your body is supposed to get the calories to function? From the stored body fat!
Hence if really insulin would trigger a fat storing mode it would
still promote fat loss by FORCING the body to use the body fat calories
instead of the carb calories as they're being stored and can't be burned.
If instead one believes that the body store carbohydrates calories
as body fat (just because of insulin presence) but doesn't take the
calories from body fat burning, then one must believe that the body
can't get the energy it needs to survive from carbohydrates.
If that scenario were true than having high insulin immediately after eating carbs would kill you in a matter of hours.
Both the ideas are completely ridiculous and the only option is that
indeed INSULIN HAS NOTHING TO DO WITH BODY FAT AND WEIGHT GAIN.
There are an host of fat storing enzymes, proteins and hormones in the body and their job is to store EXCESS CALORIES as body fat.
If there's no EXCESS CALORIES there's nothing to store. Storing normal calories that are not in excess would either result in almost instant death or in weight loss.
Even without looking at the long term metabolic ward studies that show that there's no difference in weight gain or weight loss when a group
of people consumes a certain amount of calories as high-carb meals
and another group consumes the same amount of calories as high-fat low-carb meals or the studies that show that feeding the same amount of calories to people with chronically high insulin levels has no effect in their fat gain compared to feeding the same amount of calories to people
with low insulin levels; it is simple a matter of logic.
His ideas on exercise are absurd. All studies show that when diet is accompained by exercise even if exercise increases appetite the calories
intake (mediated by this appetite) is still lower than the calories consumed during the exercise. In other words exercise does promote fat loss.
Not to mention that many people lose weight from diet just to find
themselves switching from overweight and fat to skinny and flabby.
The reason is that dieting and losing weight is just a component
of what is needed to become lean, thin and healthy.
Building lean body mass and preventing lead body mass loss while losing fat is even more important than dieting to really take advantage of the fat loss. Many people are dissatisfied with their fat loss because losing fat just allow them to uncover the skinny person below that fat. It's muscles that make people (either men, women or children) lean, firm and toned and remove the flabbiness and sagginess.
Fat-phobia was a nonsense but this carb-phobia is not any different
and almost dumber. Low carb diets work. They work because fat
(for many) is satiating and filling.
People who are lean by nature and never seem to gain fat are
gifted. They're not genetically gifted though! Their gift is an intact
instinct that allows them to know when they're in an energy balance and
to eat accordingly to such instinct.
Many people seem to restore such instinct when they lower their carbs intake and raise their fat intake and it makes sense, since we were never meant to consume 10% fat diets that only by artificially removing the fat from every food on earth can be accomplished.
Also people who have problems with their sugar metabolism become victims of the physiologically raveous hunger. Decreasing carbs, increasing fats and getting a better glycemic control allow them to remove such ravenous unhealthy hunger.
There are good reasons to choose to lower carbs and eat more fats.
The nonsensical, illogical and (if true) counterproductive to survival,
magical effect of low carb diets is not one of them!
Weight gain and fat gain still depend on an energy balance and besides
the studies and evidences proving this, it is also the only logical
way the body could work as any other way would result in metabolically
dangerous messy circumstances.
Carbohydrates and insulin are not evil and without insulin we would be dead. And this is way people on no-carb diets still have as much insulin in their body as any person eating 50% carbs.
If you look at the data from 100 years ago you can see that we ate MORE CARBS and consumed little less calories but were very physical active and daily sedentarity was unknown. Whenever we wanted to reach a place, fix something, spend free time, spend time with friends, play, work ... it involved physical activity.
Only nowadays physical activity is such an option and a person doesn't
get bored or does get things done even without physical activities.
We consume more calories and are very sedentary and this is enough to explain the weight loss incidence of the last years.
