Lose weight healthy and without regaining the lost pounds: dream or reality? According to three important scientific researches, healthy weight loss and maintaining the right weight forever is possible if we naturally accustom the body to be satisfied with the right food, without drastic interventions such as the control of calories, macronutrients and portions.
For this to be possible, it is necessary to go back to trusting one’s instinct , to feed it, to listen to it: both wild animals and small children (within three years of age) eat when and how much they want, and never more. This sense of self-regulation diminishes over time, due to a learned dietary education .Those with small children are often afraid that their child will not eat enough, but small children, like animals, have an instinctive sense of satiety. This means they can automatically measure out the portions they’re hungry for, and never eat more.
Over time, however, this sense is lost: a little for the education to eat at certain times and contexts, but even worse because many industrial foods “get high” this innate thermometer of satiety.
We have seen, however, that you can go back to listening to your hunger and your instincts, and that in this way it is possible not only to lose weight healthy, but also not to gain weight again. 
Every diet, while working to lose weight, imposes a further restriction: of foods, portions, calories. We learn to look at food from a mathematical point of view, and to demonize it. The more a person has followed weight loss regimes over the years, the harder it will be for that person to recognize genuine hunger from food cravings. Genuine hunger is one that you would eat anything, the desire drives you to eat foods you have been conditioned to eat.

La nutrizionista Carolyn Dunn spiega che su cinque studi effettuati su persone che hanno provato a seguire la loro fame genuina per mangiare, solo in uno degli studi una percentuale del campione ha guadagnato peso. In tutti gli altri casi, le persone sono dimagrite poco per volta. Perché ciò succeda, secondo la nutrizionista, oltre che a smettere di fare diete e contare le calorie, è necessario focalizzarsi sul cibo a ogni pasto, evitando di distrarsi. Scegliere cibo di qualità, che sia buono e nutriente, e che possa soddisfarci. Far durare ogni pasto non meno di mezzora, masticando lentamente e prendendosi delle pause.
Questo vuol dire anche che non appena ci sentiamo sazi, dobbiamo smettere di mangiare. Lasciare gli avanzi se serve.
But stop. Over time, it will be easier to figure out the ideal portion for our hunger. At the same time, to help your body regain its instinct for hunger, it is necessary to reduce industrial foods, preferring simple foods, and many vegetables. These are things that fail the first time, but if they succeed, they allow you to lose a bounty in a year without effort.
