What to Eat When You Quit Smoking (and How to Avoid Weight Gain)

Why quitting changes your appetite

• Your taste and smell come back. Food tastes better, so you may want more of it.
• Your metabolism slows down a little without nicotine.
• Your hands and mouth miss the habit. Snacking easily fills the gap a cigarette left.

How much weight do people gain?

A review of studies published in the BMJ found that people who quit without medication gained about 1 kg in the first month, about 2.9 kg by 3 months and about 4.7 kg by 12 months on average. Most of it comes in the first 3 months. But averages hide a wide range: about 16% of people lost weight, and about 13% gained more than 10 kg.

That’s why the first 3 months are the time to plan your eating, not to go on a strict diet.

Foods that make cigarettes taste worse

A Duke University study of 209 smokers found some foods and drinks make cigarettes taste worse, and others make them taste better.

Makes cigarettes taste worse	Makes cigarettes taste better
Milk and cheese	Alcohol
Water and juice	Coffee, tea and cola
Fruit and vegetables	Meat

Use the left column when a craving hits, and be careful with the right column in the first few weeks.

What to Eat When You Quit Smoking: A Simple Plan for Your First Weeks

1. Eat regular meals. Skipping meals makes cravings and snacking worse.
2. Add protein to each meal (eggs, yogurt, chicken, beans) so you stay full longer.
3. Keep crunchy snacks ready: carrots, celery, apples, cucumber.
4. Drink water through the day, especially when a craving hits.
5. Cut your coffee in half. After you quit, your body processes caffeine more slowly, so the same cups feel stronger.
6. Go easy on alcohol. It makes cigarettes taste better and lowers your guard.
7. Plan your evenings. That’s when most mindless snacking happens.

Frequently asked questions

Will I gain weight when I quit smoking?

Many people gain some weight, mostly in the first 3 months, but not everyone. About 1 in 6 people lose weight. Planning your meals and snacks makes a big difference.

Should I go on a diet while I quit?

It’s usually better to focus on quitting first and eat sensibly. A strict diet on top of withdrawal makes both harder.

What should I eat when a craving hits?

Something crunchy or a glass of milk or water. Fruit, vegetables, milk and water make cigarettes taste worse.
