Why am I always hungry in winter?

Cold, dark months can make you hungrier for a mix of reasons. Less daylight, poorer sleep, a lower mood and a change in routine all push appetite up.

This article explains what is going on, and what can help. It also covers how weight loss medicines such as Wegovy and Mounjaro change hunger, for adults who qualify.

Why am I always hungry in winter?

Winter hunger is usually a mix of less daylight, poorer sleep, lower mood and a change in daily habits. It is common, and it rarely means anything is wrong.

Cravings often lean towards bread, pasta, biscuits and sweet food. These foods feel comforting when you are tired or low.

If your hunger is new, extreme, or comes with a lot of thirst, weight loss you cannot explain or tiredness that does not lift, see your GP. They can check for things like diabetes or a thyroid problem.

What makes appetite stronger in dark, cold months?

Less daylight and lower mood

Short days affect mood for many people. Some notice a clear seasonal low, and a low mood often brings a pull towards carbohydrate-rich comfort food.

If your mood feels very low for more than a couple of weeks, speak to your GP.

Poorer or shorter sleep

Poor sleep is closely linked to feeling hungrier. After a bad night, many people feel more drawn to snacks and larger portions the next day.

Dark mornings and late evenings indoors can shift your sleep pattern. Even small changes can show up in your appetite.

Routine changes

Winter changes how you eat and move. Common shifts include:

• Fewer walks and less outdoor activity

• More time sitting at home in the evening

• Heavier, warmer meals

• More snacking while watching television

• Festive food and drink around the house for weeks

Boredom and habit can feel like hunger. Eating because it is 9pm and cold is different from being physically hungry.

Is it the cold itself?

The evidence that cold alone makes most people eat much more is limited. The bigger effects usually come from sleep, mood and routine.

What can help with winter hunger?

Small changes often make a difference:

• Keep meals regular, so you do not arrive at the evening very hungry

• Include protein and fibre at each meal, as they keep you full for longer

• Get outside in daylight, ideally in the morning

• Protect your sleep, with a steady bedtime and wake time

• Keep tempting snacks out of easy reach

• Cut back on alcohol, which lowers your guard around food

If you have tried these and constant hunger is making weight hard to manage, medicine may be worth discussing.

How do GLP-1 medicines affect hunger?

GLP-1 medicines make you feel fuller sooner and for longer, and can quieten the constant thoughts about food. Wegovy and Mounjaro are both weekly injections.

GLP-1 is a natural gut hormone released after eating. These medicines copy its effect.

They work in two main ways:

• They act on the appetite centres in the brain, so you feel satisfied with less

• They slow how fast the stomach empties, so fullness lasts between meals

They do not remove winter triggers such as poor sleep or low mood. They work best alongside changes to eating and activity, and results vary from person to person.

Wegovy

Wegovy contains semaglutide. The dose starts at 0.25mg and rises in steps through 0.5mg, 1mg and 1.7mg to a maintenance dose of 2.4mg. Each step is confirmed at a face-to-face review.

Mounjaro

Mounjaro contains tirzepatide. It starts at 2.5mg for four weeks, then moves to 5mg. It can then rise in 2.5mg steps to a maximum of 15mg.

Both are started low on purpose, to let your gut adjust.

Who can have weight loss treatment?

Treatment is for adults with a BMI of 30 or above. It may also suit a BMI of 27 or above with a weight-related condition, such as type 2 diabetes, high blood pressure or sleep apnoea.

The BMI thresholds are lower by 2.5 for people of South Asian, Chinese, other Asian, Middle Eastern, Black African or African Caribbean background.

Being hungry in winter alone does not make someone eligible. The pharmacist checks your height and weight on the day, and reviews your health and medicines.

Who it is not suitable for

Treatment is not suitable if you:

• Are pregnant, breastfeeding or trying to conceive

• Have an active eating disorder

• Have had pancreatitis

• Have a personal or family history of medullary thyroid cancer or MEN 2

Take extra care to mention gallbladder disease, severe gut problems, insulin or a sulfonylurea for diabetes. If you take the contraceptive pill, absorption can be affected, so extra precautions are advised when you start and after each dose increase.

What are the side effects?

The common ones are:

• Nausea

• Constipation or diarrhoea

• Reflux and burping

• Tiredness

They are usually worst in the days after a dose increase, and often settle. Eating smaller, simpler meals helps.

Severe stomach pain, signs of an allergic reaction or sudden vision changes need prompt medical help.

What happens if you stop?

Weight regain after stopping is common if eating habits have not changed. Appetite often returns as the medicine leaves your system.

This is why the pharmacist reviews you monthly and talks through food, activity and sleep alongside the medicine.

Common questions

Is it normal to crave sweet food in winter?

Yes. Low mood, poor sleep and comfort habits all raise the pull of sweet and starchy food. It usually eases as days lengthen.

Will Wegovy or Mounjaro stop winter cravings?

They often reduce appetite and food thoughts, but they do not work the same for everyone. They are a tool alongside better sleep and eating habits.

Do I need my GP to refer me?

No. At Kenmakos Medical you book directly. The pharmacist assesses you in a consultation before any prescription is issued.

Your GP can also discuss weight and appetite with you on the NHS, though availability varies.

How often are reviews?

Reviews are monthly and face to face. Weight and side effects are checked, and you decide together whether to hold or increase your dose.

How much does it cost?

Wegovy starts at £129 for the first four weeks at 0.25mg, and the price rises with the dose. The pharmacist confirms the full cost before you commit to each supply.

Does it hurt to inject?

The pens use a fine needle, and most people find it easy. Injection training is given, so you can do it confidently at home.

Kenmakos Medical is a private pharmacy in Bletchley, Milton Keynes. A GPhC-registered pharmacist will talk through whether treatment suits you, and appointments are often available the same day or within a few days.
