We’ve all heard of personalized slimming plans: these famous personalized diet plans take into account our food preferences, body type, allergies, and activity levels to burn our extra pounds quickly.

But what should we really think of these personalized diet plans? Do they allow you to lose weight faster than “classic” diets? Or is it a simple marketing trick used by the weight loss industry to attract more customers? Our team is here to find out.

Thousands of men and women now swear by personalized slimming plans: these “tailor-made” diet plans take into account our food preferences, body index, age, and body type to melt away extra pounds as quickly as possible. At least that’s their big promise1

According to several nutrition specialists, tailor-made diet plans indeed have a better chance of working than conventional diets, provided you pay attention to certain scams on the market2

“Some people try to lose weight, but the diet they’re on isn’t really suited to their metabolism,” says Lorraine Brennan, professor of nutrition at Dublin University College.

Dr. Cécile Hamont, a nutritionist and dietitian based in Paris, also seems to give the advantage to personalized diets, however warning users:

“While personalized diet plans developed by qualified nutritionists remain one of the most effective ways to lose weight permanently, there are now many so-called ‘personalized’ plans that turn out to be completely ineffective, even lying,” explains Dr. Hamont3.

In this article, we gave the floor to several nutrition experts on how to choose a reliable and effective personalized diet plan, while avoiding scams. For our interested readers, we also offer a personalized diet plan suggestion recommended by several nutritionists.

Why do the vast majority of diets fail after just one month?

According to a British study conducted by the Medical Research Council, more than 90% of diets fail. Worse: The vast majority of people who start a diet end up weighing more than their original weight4

This is the famous “yo-yo effect” everyone has already heard of. Thousands of people looking to slim down their line suffer from this yo-yo effect every year:

They begin a new diet full of enthusiasm and motivation.

They manage to lose a few pounds in a few weeks while maintaining an iron will.

But after a while… their bodies end up cracking, and they throw themselves into eating their favorite dessert, candy, or “cheat meal.”

But how come people always end up cracking up? Why do most conventional diets almost always fail?

According to specialists, there are two main reasons for this.

The first is that most mainstream diets are “rejected” by our metabolism5. As Vienna-based nutritionist and dietary researcher Dr. Carl Brunninger explains:

“The majority of popular diets (keto, Atkins, Dukan, low-carb, etc.) are doomed to fail for a large portion of the population. Why? Because they are simply not suited to our metabolic preferences, which are completely unique and extremely difficult to change.”

(We’ll explain later in this article how to choose a personalized diet that can eliminate the “yo-yo effect” for good).

The second reason why mainstream diets don’t work for millions of people is that our metabolism reacts in completely unpredictable ways to the foods we eat6

In other words, eating caramel ice cream can lead to the storage of fat in one person and produce nothing at all in another…

This is what has led many weight loss experts to strongly criticize mainstream diets:

“Our recommendations, both medical and public health, were based on the principle that if people followed a standard diet, they would lose weight and develop fewer chronic diseases,” says Dr. Tim Spector. “In reality, this reasoning is now completely erroneous”6.

It is for these reasons, among others, that the so-called personalized diets are becoming more and more popular.

Can personalized plans really make us lose weight faster than conventional diets?

Unlike regular diets, personalized diet plans have a reputation for being completely tailored to our metabolism and food preferences. But are they really more effective than conventional diets?

According to several experts, it seems that this is indeed the case. As the prestigious Harvard School of Public Health reports:

Precision nutrition [a diet personalized to our unique metabolic needs] is based on the principle that each person reacts differently to certain foods and nutrients, which implies that the best diet for one person may be completely different from the best diet for another.7

And according to Dr. Cécile Hamont:

In the vast majority of cases, tailor-made diet plans turn out to be much more effective than standard diets in losing weight, and above all preventing the yo-yo effect in the medium to long term.

However, despite the effectiveness of these tailor-made plans, it would be a mistake to jump on personalized diet plans with your eyes closed…

When personalized diet plans turn into a marketing scam… And how to choose a reliable personalized diet

“Many of the ‘personalized’ plans available online are not reliable at all. They are not made by qualified nutritionists. They do not take into account your body type, your body index, or your lifestyle. As a result, many people end up following generic plans that don’t match their metabolic needs at all. Be aware that the weight loss industry is very unregulated, so scams are quite common,” emphasizes Dr. Hamont.

    This book has really helped me to maintain a healthy diet. I used to not pay too much attention to what I bought while shopping, and it was very tempting to pounce on a box of cookies whenever I had the chance. Now I only buy the bare essentials, what I really need to prepare healthy meals. This book has been a huge help in creating that habit.
