Neuroscience and Metabolism to Control Weight Without Diets
The definitive method to achieve it without diets, without stress, without rebound effects. The smart path to lose weight and keep it off.
Introduction:
“I Beat the Scale” “I Beat the Scale” speaks to you directly, without detours or false promises. It acknowledges the frustration you feel if you’ve tried strict diets only to regain the lost weight. The book empathizes with your experience, understanding that it’s not about a lack of willpower, but rather that traditional diets don’t address the root of the problem: your habits, your emotional relationship with food, and your mental programming.
The book begins by challenging the conventional wisdom of restrictive diets. It argues that these diets often lead to the “rebound effect,” trapping people in a cycle of weight loss and regain. The key to success lies not in willpower, but in creating automatic habits. The author explains that willpower is limited and depletes over time, especially when used to resist temptations.
The proposed solution is to reprogram the brain to work in your favor, establishing healthy habits that are carried out unconsciously and effortlessly.
This book is not a diet manual, but a guide to changing the mindset and habits that prevent you from achieving a healthy and sustainable weight.
This book is not just another restrictive diet manual. It’s not about eliminating carbs, counting calories, or going hungry. Instead, it offers a different path, based on neuroscience, behavioral psychology, and the science of habit change, so that losing weight is effective, lasting, and free of suffering.
The introduction debunks the idea that losing weight depends solely on willpower. It recognizes that willpower is limited and wears out. The true secret lies in creating automatic habits, actions you perform without conscious effort. The book will teach you to reprogram your brain to work in your favor.
The book’s approach is innovative and hopeful. It draws inspiration from authors like James Clear, Tony Robbins, and Dr. Jason Fung. It will guide you to:
Identify and replace the habits that make you gain weight.
Build healthy routines that last long-term.
Understand how food affects your brain and emotions.
Apply strategies to maintain motivation and prevent setbacks.
Create an environment that supports weight loss without sacrifices.
By the end of this book, you will not only have learned to lose weight, but you will have developed a new identity: that of a fit, healthy person in control of their habits. You won’t be someone “on a diet,” but someone who has permanently changed their lifestyle.
In summary, the introduction invites you to leave behind quick fixes and extreme approaches and embrace a deep, sustainable transformation process. It assures you that everything you need to achieve a healthy weight for good is within your reach. Are you ready to change your life? Let’s get started!
Part 1: The Science of Body Weight and Habits
This section of the book delves into the scientific foundations that explain why we gain weight and why traditional diets often fail. Instead of simplifying weight loss to the mere equation of “calories consumed vs. calories burned,” the author explores the complexity of the metabolic, hormonal, and psychological factors that influence weight. The goal is to provide the reader with a deep understanding of how their body works so they can take control of their health in an informed way.
Chapter 1: The Truth About Obesity and Overweight
Why do we gain weight? The book explains that weight gain is a multifactorial phenomenon. It’s not just about overeating, but a complex interplay of metabolic, hormonal, and psychological factors.
Metabolic Factors: Metabolism, the way the body converts food into energy, plays a crucial role. Factors such as age, body composition (muscle mass vs. fat), physical activity level, and genetics influence the metabolic rate. Restrictive diets can slow metabolism as a survival mechanism. The gut microbiota also affects digestion, nutrient absorption, and weight regulation. An imbalance in gut bacteria can promote fat storage and increase resistance to weight loss.
Hormonal Factors: Hormones are chemical messengers that control appetite, satiety, and fat storage. The book focuses on key hormones such as insulin, leptin, ghrelin, GLP-1, CCK, serotonin, and cortisol. An imbalance in these hormones can lead to weight gain and make weight loss more difficult.
Psychological Factors: The relationship with food is influenced by emotions, habits, and beliefs. Eating due to stress, anxiety, or boredom can sabotage weight loss efforts. Limiting beliefs about food and the body can also shape dietary decisions and self- perception.
The Role of Hormones in Weight Regulation:
Insulin: This hormone, secreted by the pancreas, regulates blood glucose levels. A diet high in sugars and refined carbohydrates can lead to insulin resistance, which promotes fat storage, especially in the abdominal area. To regulate insulin, it is recommended to reduce the consumption of added sugars and refined carbohydrates, increase the intake of proteins and healthy fats, practice intermittent fasting, and perform strength exercise.
Leptin: Produced by fat cells, leptin sends signals to the brain to indicate satiety. In people with overweight and obesity, leptin resistance can develop, meaning the brain doesn’t properly receive the satiety signal, and the person continues to feel hungry. To improve leptin sensitivity, it is recommended to
sleep at least 7-9 hours per night, reduce the consumption of ultraprocessed foods and those rich in trans fats, engage in physical activity, and maintain stable blood glucose levels.
Ghrelin: Known as the “hunger hormone,” ghrelin is produced mainly in the stomach and increases before meals. Restrictive diets and lack of sleep can disrupt ghrelin production, causing a constant feeling of hunger. To regulate ghrelin, it is recommended to eat balanced meals with a good combination of proteins, healthy fats, and fiber, avoid extremely restrictive diets, get enough sleep, and reduce stress.
GLP-1 Incretin System: GLP-1 is a hormone secreted in the small intestine in response to food intake. It stimulates insulin release, increases the feeling of satiety, and slows gastric emptying. To optimize GLP-1, it is recommended to consume a diet rich in fiber and proteins, avoid excessive consumption of sugars and refined flours, and include fermented and prebiotic foods.
CCK (Cholecystokinin): This intestinal hormone is released in response to the intake of fats and proteins and sends signals to the brain to indicate satiety. To optimize CCK, it is recommended to include proteins in every meal, incorporate healthy fats, and chew slowly.
Serotonin: This neurotransmitter is key in regulating mood and controlling appetite.
Cortisol: Chronic stress elevates cortisol levels, a hormone that promotes fat storage, especially in the abdominal area. Strategies such as meditation, exercise, and a proper sleep routine can improve hormonal regulation and weight control.
Myths About Weight Loss: The book debunks mistaken beliefs that can sabotage progress. Some of these myths include:
“Eating less and moving more is the ultimate solution.” “Fats make you fat.”
“‘Light’ and ‘sugar-free’ products help you lose weight.” “Eating at night makes you gain weight.”
“Cardio is the best way to lose weight.”.
Chapter 2: The Power of Habits in Weight Loss
How the Brain Automates Behaviors: The brain is an efficiency machine that
automates repetitive tasks through the formation of habits. Habits can be beneficial (eating healthily, exercising) or harmful (overeating due to anxiety, leading a sedentary lifestyle).
The role of the basal ganglia: hese brain structures are responsible for automating habits. When a repetitive action is performed, the brain creates a “neural pathway” that makes it more automatic each time.
Good habits vs. bad habits: The brain reinforces habits through dopamine, a neurotransmitter related to pleasure and reward. It is important to associate balanced eating and exercise with pleasurable experiences so that the brain strengthens these behaviors.
The habit loop: All habits, both good and bad, follow the same pattern: trigger, routine, reward.
Trigger (cue): This is the element that activates the habit. It can be an external event (the time of day, seeing a food advertisement) or an internal one (an emotion such as anxiety).
Routine: This is the behavior itself, what is done in response to the trigger.
Reward: This is the gratification obtained after completing the routine.
The key to changing harmful habits is to keep the same trigger and reward but change the routine.
In summary, Part 1 of the book lays the groundwork for understanding the complexity of body weight and how habits influence it. By understanding the metabolic, hormonal, and psychological factors, as well as the habit loop, the reader will be better equipped to approach weight loss effectively and sustainably. This section provides the necessary knowledge to challenge quick fixes and adopt a more holistic and personalized approach.
Part 2: Strategies for a Lasting Transformation
