When it comes to treating diabetes, obesity and epilepsy, low carb diets have been used for many years as a therapeutic tool.
Millions of people have been very successful with it.
In spite of all of this, nutritionists and other health experts do not recommend a low carb diet citing that it can be too dangerous and unhealthy in the long run.
Many claim the scientific evidence behind low carb diets is insufficient and refer to them as a ‘fad’ diet.
In this article, I will prove them wrong.
Ten years ago, there was not much scientific evidence behind the low-carbohydrate diet, however since 2003, there have been over 27 randomized, controlled, scientific human trials.
Randomized controlled trials are the gold standard in the public health and medical science community that prove safety, cause and effect.
In this article, I will review 27 trials that were published in the New England Journal of Medicine, American Journal of Clinical Nutrition and Nature (2003-2016)
Over the years, I have asked Nutritionists and other health experts who are against low-carb diets to prove they are ineffective or unsafe. The fact is – such trials do not exist.
All of the randomized controlled trials compare the low-carb diet to the standard, calorie-restricted, low-fat diet that is often recommended by many health professionals.
There is no one diet plan that is perfect for everyone.
The best eating plan is one with lifestyle habits and changes that can be easily followed by an individual for life.
My goal is for the media, general public and health professionals to acknowledge low-carb diets as a viable option for those dealing with obesity, diabetes, and symptoms of metabolic syndrome – a condition that is becoming quite prevalent throughout the world.
All the scientific evidence suggests that a low carb diet is easier, healthier and more effective than a calorie-restricted, low-fat diet that is often recommended by health professionals.

Details: In 2003, the Journal of Pediatrics conducted a 12-week study to determine the effects of a low-carbohydrate diet on overweight, adolescent individuals with risk factors for cardiovascular disease.
The study consisted of 30 individuals who were randomly placed in a either a low-carbohydrate or low-fat group without restriction of calories.
Results Of The Study: The low-carbohydrate group lost an average of 21.8 pounds while the low-fat group lost an average of 9 pounds. Plus, the low-carbohydrate group had significant improvements in their triglyceride and cholesterol levels.

Details: In 2003, The Journal of Endocrinology and Metabolism conducted a randomized trial that compared a low-carbohydrate diet and a calorie-restricted, low-fat diet in healthy women.
The study looked at cardiovascular risk factors as well as body weight.
The study lasted six months and included 53 obese women who were randomly placed in.
Results Of The Study: The low-carbohydrate group lost an average of 18.7 pounds while the low-fat group lost an average of 8.6 pounds.
5. Aude YW, et al. The national cholesterol education program diet vs a diet lower in carbohydrates and higher in protein and monounsaturated fat. Archives of Internal Medicine, 2004.
Details: 60 participants were randomized to either a modified low-carb diet or a low-fat diet based on the National Cholesterol Education Program. Both groups are calorie restricted.
Weight Loss: The modified low-carb group lost an average of 13.6lb (6.2kg) while the low-fat group lost an average of 6.1lb (2.8kg).
Cardiac Risk Factors: There were no significant differences in blood lipids between groups. The modified low-carb group decreased total cholesterol, triglycerides, and percentage of dense LDL while increasing LDL particle size. The low-fat group decreased total, HDL and LDL cholesterol.
6. Yancy WS Jr, et al. A low-carbohydrate, ketogenic diet versus a low-fat diet to treat obesity and hyperlipidemia. Annals of Internal Medicine, 2004.
Details: There were 119 obese, hyperlipidemic individuals randomly assigned to either a low-carbohydrate, ketogenic diet or a low-fat diet group. Calories were restricted in the low-fat group.
Weight Loss Results: The group on the low-carb diet lost an average of 12.0 kg or 24.0 pounds, while the low-fat group lost an average of 6.5 kg or 13.0 pounds.
Results Of The Study: Those on the low-carb diet experienced decreased triglycerides while HDL cholesterol levels increased.
The group on the low-fat diet experienced a lowering of total cholesterol and decreased triglycerides.
In fact, there was a significant difference between the groups when measuring for triglycerides and HDL levels, that prove the low-carb diet was successful.
7. JS Volek, et al. Comparison of energy-restricted very low-carbohydrate and low-fat diets on weight loss and body composition in overweight men and women. Nutrition & Metabolism (London), 2004.
Details Of The Study: There were 28 overweight men and women randomly assigned to eat a calorie-restricted, low-carb diet or a calorie-restricted low-fat diet. The low-carb group ate 300 more calories per day.
The outcomes measured included weight loss, body composition, trunk fat mas and resting energy expenditures for both groups.
Weight Loss: In spite of eating more calories per day, the low-carb group lost more weight than the low-fat group.
Naturally, the men lost more weight than the women. The ratio of trunk fat and total fat also decreased for those on the low-carb diet, meaning they lost more abdominal fat, the most dangerous kind of body fat.
Results Of The Study: For those on the low-carb diet, resting energy expenditure did not decrease, however, it did decrease for those on the low-fat diet.
The loss of fat in the trunk or abdominal region was three times greater for those on the low-carb diet compared to those on the low-fat diet.

23. Guldbrand, et al. In type 2 diabetes, randomization to advice to follow a low-carbohydrate diet transiently improves glycaemic control compared with advice to follow a low-fat diet producing a similar weight loss. Diabetologia, 2012.
A clinical study published in Diabetoligia showed those who have type 2 diabetes have success in controlling blood sugar levels more successfully with a low-carbohydrate diet as opposed to following a low-fat diet. (Diabetoliga, 2012)
Details: The study included 61 people who had type 2 diabetes randomly chose a either a low-carbohydrate or low-fat eating plan and agreed to follow it for two years with restrictions in calories.
The results were amazing. Individuals who followed a low-carbohydrate plan lost twice as much weight (on average 6.8 pounds) as those who followed a low-fat diet (average 7.9 pounds), however statistically, the difference was not significant.
24.A systematic review: Impact of dietary macronutrient distribution on BMI and cardiometabolic outcomes in overweight and obese children and adolescents: , Oxford Journals, 2014.
A Systematic Review was completed in 2012 that looked at macro-nutrient diet and their effect of percentages of protein, fats, and carbohydrates instead of calories alone on obese children and adolescents.
The objective of the study is to determine the effect on metabolism in overweight children and adolescents when placed on a ketogenic diet that high protein and fat diet with about 50 grams of carbohydrates per day and hypocaloric diet in which individuals simply eat less calories than what they burn.
The two different diets were implementd on 58 individuals (both children and adolescents) for a period of six months.
The method for measuring results included measuring height, weight, skin-fold thickness and circumference of the waist, hips and chest. A lipid profile that is a panel of blood tests that measures cholesterol and triglyceride levels is also completed.
Before and after each diet, an assessment is done to determine if an individual is experiencing insulin resistance.
Both children and adolescents lost weight, inches and improved insulin levels, however those on the ketogenic diet experienced the greatest improvements. Both groups increased their Whole Body Insulin Sensitivity Index (WBISI) considerably, however those on the ketogenic diet increased their high-molecular weight adiponectin (HMW), a fat-burning hormone.
Children experienced greater weight loss on a ketogenic diet and is proven to be a safe alternative for signficant improvement in all metabolic factors related to weight loss.
25.The Annals Of Internal Medicine (2014) published a study that focused on the effects of low-carbohydrate and low-fat diets, a randomized trial.
The objective of the study was to test and compare the cardiovascular risk factors and body weight on a low-carbohydrate diet verses a low-fat diet.
Both men and women in the study (148 in total) did not have diabetes or clinical cardiovascular disease.
At the end of the study, 82% of those in the low-fat group and 79% of the low-carbohydrate group completed their program. Those on the low-carbohydrate diet lost more weight and body fat than those on the low-fat diet.
Weight loss results: those on the low-carbohydrate diet experienced a greater reduction in weight and improved cardiovascular risk factors than the low-fat diet participants.
Eating a low-carbohydrate diet is an effective way to lose weight and improve health.
Information was tracked through 17 trials with 1,797 patients over a one-year period comparing low-carbohydrate and low-fat diets.
Those who consumed a low-carbohydrate diet experienced greater weight loss than those on strictly a low-fat diet. Plus, those on the low-carbohydrate diet signiticantly reduced their risk factors for cardiovascular disease.
27. British Journal of Nutrition: Effects of low-carbohydrate diets v. low-fat diets on body weight and cardiovascular risk factors: a meta-analysis of randomised controlled trials – 2016
The Atkins diet was used in the study featuring low-carbohydrate consumption of less than 20% of total caloric intake per day for at least six months or longer in healthy individuals.
Those on the low-carbohydrate diet (Atkins diet) experienced more weight loss compared to those on the low-fat diet.
In conclusion, cardiovascular risk factors were significantly reduced in those on the low-carbohydrate diet that included significant weight loss, however LDL cholesterol levels increased.
I went through all of the studies (2003-2016), took me about 2 weeks.
Weight Loss on Low-Carb vs. Low-Fat Diets
Weight loss is, almost without exceptions, greater on low-carb diets although the difference isn’t always statistically significant.
This effect is especially evident when the low-carb group is allowed to eat until fullness while the low-fat group is calorie restricted, which is how these diets are usually prescribed in practice.
When both groups eat the same amount of calories (isocaloric), the low-carb groups still tend to lose more weight but the effects aren’t large enough to reach statistical significance.
Part of the reason for greater weight loss on the low-carb diet given that calories stay the same may be increased water loss.
Calories, Carbs, Fats and Protein
When the low-carb group is not calorie restricted but the low-fat group is, they tend to end up eating a similar amount of calories. Interestingly, calorie restricted low-fat dieters also end up eating a lower total amount of carbohydrates.
Another interesting observation is that on a low-carb diet, people don’t necessarily end up eating more fat than they used to. In fact, they tend to eat similar amounts of fat as they were before starting the diet.
Protein intake is higher on the low-carb diet, which may explain some of the increased satiety.
Appetite And Hunger
Low-carb diets tend to decrease appetite and hunger.
This is the main reason people lose so much weight without portion control or calorie restriction, they simply don’t want to eat as much.
Compliance and Attrition Rates
The studies where the LC diets are most effective are where people manage to follow them completely and restrict carbohydrates accordingly.
However, as with every weight loss diet, compliance is an issue and people tend to increase their carb intake over time. As carb intake increases, weight loss tends to slow down and some people even start gaining weight back.
This implies that weight loss on a LC diet (as with any diet, really) requires people to stick with it for life.
Attrition rates tend to be lower on LC diets (more people make it to the end) despite arguments by dietitians about LC diets being harder to stick to because they eliminate entire food groups.
This is probably due to the fact that people can eat until fullness and don’t have to be hungry all the time, which is common with calorie-restricted low-fat diets
The idea that low-carb diets are harder to follow is a myth!
LDL and Total Cholesterol levels
Low-fat diets tend to decrease both Total and LDL cholesterol, but mostly in the first 3 months or so. Then they tend to go back up.
It is not true that low-carb diets raise LDL or Total cholesterol levels. The fact is that they remain pretty much the same. They don’t get any higher than before, although there is some individual variation here.
This is probably nothing to worry about, as low-carb diets tend to change the LDL pattern from small, dense LDL to large, fluffy LDL which is benign.
HDL Cholesterol levels
HDL cholesterol (the “good” cholesterol) usually goes up substantially on a low-carb diet, while it tends to increase less or even go down on a low-fat, high-carb diet.
Blood triglycerides always go down on low-carb diets, while they tend to decrease less, stay the same or go up on calorie-restricted low-fat diets.
Blood pressure seems to decrease for both low-carb and low-fat dieters and the difference usually isn’t significant between groups.
Glucose, Insulin and Type II Diabetes
Glucose and insulin tend to decrease further on low-carb diets in non-diabetics, but it is not always statistically significant.
In type II diabetics, glucose and insulin levels decrease much more on low-carb diets and the patients are often able to eliminate or drastically reduce medication.
This implies that these diets may be particularly useful for those with diabetes or impaired glycemic control.
There were some mild side effects for those on the low-carb, ketogenic diets that usually last only a few days. Some experienced headache, nausea, fatigue, insomnia and constipation.
However, there were no serious side effects from eating a low-carb, ketogenic diet, in spite of some of the scare tactics and/or misinformation.
It Is Time To Dispel The Myths
When it comes to weight loss, low-carb, ketogenic diets work more effectively than low-fat diets. In addition to weight loss, they help reduce the major risk factors of many diseases including diabetes and heart disease.
The studies prove that low-carb diets are healthier and far superior compared to low-fat diets. The low-carb diet is especially effective for those with diabetes, metabolic syndrome and obesity.
More weight loss can be achieved with a low-carb diet as opposed to low-fat, calorie-restricted diets, without being hungry. Let’s face it – being hungry all the time is not a way to live.
Triglycerides, HDL and LDL cholesterol levels all improved for those on the low-carb diet, further reducing their risk for disease compared to those on the low-fat diets.
The most effective way to lose weight and reverse metabolic disease is through a healthy, low-carb diet. The science behind this statements proves it.
It is time to dispel the myth about low-fat diets, once and for all.
