Why All Diets Fail After Two Months

Dr. Robert Lustig, MD, states a sobering fact based on clinical evidence: every diet works, but only for the first two months. He references the famous "A to Z study" conducted by his colleague, Dr. Christopher Gardner at Stanford University. This research tested four different popular diets against each other and found identical short-term success across all plans.

The study's crucial finding was that the initial weight loss was not sustainable. After the two-month mark, participants were no longer adhering strictly to their assigned diets. Different, often unhealthy, food items had seeped back into their daily intake, effectively destroying the diet's efficacy. Dr. Robert Lustig, MD, explains this phenomenon makes perfect sense through the lenses of addiction psychology, human desire for variety, and the biochemistry of hormones like leptin.

The One Thing All Successful Diets Have in Common

Dr. Robert Lustig, MD, then analyzes the top diets, including Atkins, Mediterranean, Zone, Sugar Busters, Traditional Japanese, Paleo, and Vegan. These plans have wildly different dietary compositions, often appearing to be complete opposites in their approach to nutrition, such as high-fat versus high-carbohydrate regimens.

Despite their surface-level differences, Dr. Lustig identifies a powerful common denominator. Every one of these diets that shows initial success shares two fundamental characteristics: they are low in sugar and high in fiber. This combination is the unifying biochemical principle behind their short-term effectiveness. Dr. Anton Titov, MD, engages with this concept, highlighting its simplicity and importance.

What is Real Food? A Clear Definition

So what do you call a diet that is consistently low in sugar and high in fiber? Dr. Robert Lustig, MD, provides the answer: it is called eating "real food." This is the core of a sustainable lifestyle change, not a temporary branded diet. Real food inherently possesses these nutritional qualities.

Dr. Lustig points out a significant problem: many people no longer know what real food is. Common misconceptions lead individuals to believe processed items like certain salad dressings or sugar-laden yogurts qualify as real food. This confusion is a major barrier to adopting a truly healthy long-term eating pattern.

The Food Industry's Role in Our Eating Habits

The widespread confusion about real food is not an accident. Dr. Robert Lustig, MD, argues that the food industry has done an exceptionally effective job over the last 35 years of indoctrinating and brainwashing the public. Their marketing and product development have shifted consumer perceptions away from whole ingredients and toward convenient, processed alternatives.

This has created a population that is, in effect, addicted to the high sugar content prevalent in commercial processed foods. The industry's success means that if you don't know what real food is, you remain a hostage to their products for life, making sustainable health nearly impossible to achieve without a conscious effort to break free.

The Critical Solution: Relearning How to Cook

For Dr. Robert Lustig, MD, the single most powerful solution to the obesity and diabetes epidemics is relearning the lost skill of cooking. He states unequivocally that knowing how to cook is the key to escaping the grip of the food industry. When you cook for yourself, you control the ingredients, ensuring your meals are high in fiber and low in sugar.

Dr. Lustig believes this is the best thing any government could do to promote public health—invest in programs that teach people how to cook real food. While this initiative costs money, the long-term savings in healthcare costs from reducing chronic disease would be monumental. Dr. Anton Titov, MD, discusses this societal challenge, underscoring that a medical second opinion on obesity often leads back to this fundamental lifestyle change.

Dr. Anton Titov, MD: Which diets work best? Prominent endocrinologist and nutrition expert Dr. Robert Lustig, MD, explains when diets work and which diets do not work.

What are two key components of "real food"? Learn about the diet that works best for you.

The top five diets in 2015 all work well for the first two months: Atkins, Mediterranean diet, Zone diet, Sugar Busters diet, Traditional Japanese diet, Paleo diet, and Vegan diet.

Do we know which diets work best today? The best, most effective diet is a real food diet. Real food is rich in fiber and low in sugar. Good diets that work are diets that are high in fiber and low in sugar.

What is real food? Many people do not know what real food is. People have to learn how to cook food at home. The food industry does not want you to cook; you can continue to be addicted to high sugar in commercial processed food.

Doctors keep asking, which diets work best?

Medical second opinion confirms that a poor diet diagnosis is correct and complete. Medical second opinion also confirms that the best diet therapy is required.

Medical second opinion helps to choose the best treatment for obesity caused by bad diet habits. Get a medical second opinion on obesity caused by bad diet and be confident that your treatment is the best.

Do you want to know which diets work best? No diet works best for an extended period of time.

Dr. Robert Lustig, MD: Let's talk about diets—any kind of diets! Is there any diet that works? If not, why not? What's the problem?

Every diet works for two months, then it doesn't work. My colleague, Doctor Christopher Gardner at Stanford University, did a very famous study called the "A to Z study."

What he saw was this: it didn't matter which diet you pick. He tested four different diets against each other. Every diet works for the first two months, then it didn't work.

The reason was because nobody was on the diet anymore. They thought they were on a diet, but they were not on any diet anymore.

Different foodstuffs had seeped back into their diet; they actually destroyed their diet. That makes perfect sense based on what we know about addiction. That is point number one.

Point number two is this: we know about humans and variety. Point number three is based on what we know about the biochemistry of leptin.

No diet makes sense. What makes sense is a lifestyle change.

Now, what is that lifestyle change? Let's look at all the diets that purportedly work: Atkins diet, Mediterranean diet, Zone diet, Sugar Busters diet, Traditional Japanese diet, Paleo diet, Vegan diet.

Diets are all over the place. They have different dietary compositions, every one of them. They are as far opposite each other as you could possibly imagine—except they are not.

In fact, they are all the same. All of these diets have been shown to work. Every one of those diets has two things in common: low sugar and high fiber.

Dr. Anton Titov, MD: Low sugar, high fiber?

Dr. Robert Lustig, MD: What is a low sugar and high fiber diet called? Real food! That's what real food has. What helps in the long term is eating real food.

The question is, what is real food? A lot of people don't know what real food is. A lot of people think salad dressing is real food; a lot of people think yogurt is real food.

This is the problem. The food industry has done such a good job of indoctrinating us. They brainwashed us, or whatever it is that they did to us over the last 35 years.

People have forgotten how to cook.

Dr. Anton Titov, MD: I will tell you right now: if you don't know how to cook, you are a hostage to the food industry for the rest of your life.

Dr. Robert Lustig, MD: We need to re-teach people how to eat. That means teaching people how to cook.

This is probably the single best thing that government could do to solve the obesity and diabetes epidemics. These epidemics are going on right now.

Government could help people get away from processed food. The problem is, it costs money. No one is willing to do it.

Atkins, Mediterranean, Zone, Sugar Busters, and Traditional Japanese diets all work for the first two months.
