A general question related to obesity before my gastric sleeve operation

The most important thing is to change the chip, you have to change habits, this is not magic, if you do not change any procedure you perform you will fail.

The idea that people with a BMI over 40 "can’t" lose and maintain weight without surgery isn’t entirely true, but it is much more difficult for most people.
When someone has a BMI over 40, it’s not just about willpower or effort. The body’s metabolism, hunger hormones (like ghrelin), and how the brain responds to food all work against weight loss. After losing a lot of weight, the body fights to regain it by making you feel hungrier and slowing your metabolism. This is why many people, like yourself, are able to lose weight but struggle to keep it off long-term.
Surgery, like the gastric sleeve, changes the way your body responds to food. It reduces hunger hormones, limits how much you can eat, and sometimes even affects how your body processes food. That’s why it’s seen as a more effective long-term option for people with a BMI over 40.
To be clear, some people with a high BMI do lose and maintain weight without surgery, but it’s rare. Surgery gives you a physical tool to make it easier, but it still takes effort, like healthy eating and exercise, to maintain the weight loss.

Hello, how are you?
Not necessarily. People with a BMI greater than 40 can lose weight and maintain their "low" weight as long as they continue with appropriate lifestyle habits: diet, exercise, emotional support, etc.
It is probably more difficult to maintain a low weight for people with a BMI greater than 40 who do not undergo weight loss surgery than those who do, since the surgery brings a series of neurohormonal, biochemical, and anatomical changes, which They make the weight loss process more "efficient" and to date it is the most effective method for sustainable (long-term) weight loss, that is, it has been shown to have better results than those people who try to lose weight only with diet, exercise or weight loss medications.
However, weight loss surgery is a great tool to lose weight, and keep that weight down, but it is very important that you continue with good eating habits, diet, exercise, emotional support, even if you have surgery.

Weight loss can be achieved through diet and exercise, and many people have successfully lost and maintained weight without surgical intervention.
That said, for some individuals, like yourself, surgery can be a valuable tool to assist in their weight loss efforts, especially if they've struggled to maintain weight loss in the past. The gastric sleeve procedure reduces the size of the stomach, leading to reduced calorie intake, early satiety, and ultimately weight loss. It can be a highly effective option for those who have had difficulty achieving and sustaining weight loss through non-surgical methods.
The key to successful weight management, with or without surgery, is adopting a comprehensive and sustainable approach to lifestyle changes, including healthy eating habits and regular physical activity. It's crucial to have a thorough discussion with your surgical team about your medical history, past weight loss experience, and your current goals to determine if the gastric sleeve is the right choice for you. They can provide you with guidance and support to help you make the best decision for your weight loss journey and overall health.
