Stopping smoking is one of the most effective steps you can take to protect your health and future. According to the World Health Organization (WHO), smoking causes more than 8 million deaths annually, while research shows quitting can add up to 10 years to life expectancy. Despite such life-saving benefits, many hesitate to quit because of a common fear of weight gain.
Studies reveal that nearly 50% of smokers worry about putting on weight after quitting, and this concern often delays their journey to freedom. But is weight gain inevitable? In this blog, we’ll break down the weight gain myth and explain how tools like the QuitSure app can help.
What Really Happens to Your Body When You Quit?
Instead of focusing on potential weight gain, let's talk about the incredible things your body does when you stop smoking:
Within 20 Minutes: Your heart rate and blood pressure drop to normal levels.
Within 12 Hours: Carbon monoxide levels in your blood return to normal, and your body starts to heal.
Within 2 Weeks to 3 Months: Your circulation improves, and your lung function increases by up to 30 per cent.
Within 1 to 9 Months: Coughing and shortness of breath decrease. Your lungs become better at cleaning themselves and fighting infection.
Within 1 Year: Your risk of heart disease drops to half that of a smoker.
Within 5 Years: Your stroke risk drops to that of a non-smoker.
Within 10 Years: Your risk of lung cancer falls to about half that of a smoker.
These benefits far outweigh any concerns about gaining a few pounds. Your body is healing, recovering, and becoming stronger every single day you stay smoke-free.
The Truth: Not Everyone Gains Weight
It has been found that although certain individuals do put on a few pounds after giving up smoking, not all of them do. Individuals can actually put on 2-5 kilogrammes within the first year of quitting. Yet, it is not a fixed amount, and numerous individuals do not gain weight; actually, they lose it after quitting.
The concept that gaining weight is inevitable is nothing more than a myth. Having the right attitude, habits and encouragement, you will be able to stop smoking and be in charge of your health and weight.
Why Would Fear of Gaining Weight Hold You Back?
This is why the myth of weight gain should not prevent you from using a quitting smoking application such as the QuitSure app:
Good Health Surpasses Risk
The small chance of putting on a few kilos is nothing as compared to the massive advantages of stopping. The risks of cancers, heart diseases, stroke and lung problems are much lower and far outweigh the weight changes.
Weight Can Be Managed
Although you may put on a bit of weight, it is only temporary and can be addressed through healthy food and physical exercises.
Improved Energy and Fitness
After having given up, your stamina increases. You are able to work out more, which balances your weight automatically.
Better Mental Health
Giving up smoking improves your mood, calms down anxiety and makes cravings less in control. This psychological resilience assists you in making more healthy lifestyle decisions in general.
The Real Numbers Behind Weight Gain
Let's look at the actual data instead of fears and assumptions:
According to the Centres for Disease Control and Prevention (CDC), about 80 percent of people who quit smoking gain some weight in the first few months.
The average weight gain is between 5 and 10 pounds, with most of this occurring within the first three months.
Only about 10 per cent of quitters gain more than 30 pounds.
Within a year, many people lose some or all of the weight they initially gained as their bodies adjust.
Studies show that only 13 per cent of men and 16 per cent of women who quit smoking gain more than 20 pounds.
The Psychological Battle
The anxiety of gaining weight tends to involve more control and identity than something to be concerned about. You may have been one of those who have been smoking to keep your weight down, and without that, it seems frightening. But smoking is an awful weight management tool. It is similar to maintaining a threatening animal as your pet because it looks good.
A smoking cessation app aids you to overcome these psychological hurdles. QuitSure contains activities that will teach you to rethink your attitude towards smoking and weight. You will be taught to dissociate with cigarettes and develop confidence in your skill to remain healthy in more and better ways.
Why Your Health Is More Than the Scale
A change of perspective that may help here is to put on an extra 5 to 10 pounds, which is far more beneficial than still smoking. The health hazards just do not add up.
Smoking is harmful to almost all organs of your body. It is a cause of cancer, heart disease, stroke, lung diseases, diabetes, and chronic obstructive pulmonary disease (COPD). It makes you more vulnerable to tuberculosis, some eye diseases and issues with the immune system.

I had an experience with Il Makiage's customer service, and I must say it was quite disappointing. The representatives seemed unhelpful and lacked the knowledge to address my concerns effectively. I expected a more personalized approach, especially given the premium nature of their products, find customer service contacts on https://il-makiage.pissedconsumer.com/customer-service.html . The response time was also slower than anticipated, leaving me frustrated. Overall, the customer service did not match the quality of the cosmetics, which is a significant drawback for a brand that prides itself on excellence.
