Mounjaro (tirzepatide) is a weight-loss injection that mimics the hormone GLP-1 to lower hunger and food-seeking behaviours.

However, everyone will respond differently to Mounjaro; some might not notice the appetite-suppressing effects immediately.

Here’s a list of five reasons why might still be feeling hungry on Mounjaro:

  1. It takes time for your body to adjust to Mounjaro: It can take up to 8 weeks for Mounjaro to reach a level known as its ‘steady state’ where it remains stable in the blood. During this adjustment phase, you may still experience hunger.
  2. The current dose might be too low: Mounjaro starts at a lower dose and gradually increases from 2.5 mg up to as high as 15 mg over 6 months to give your body time to adjust to the medication and reduce side effects. You might not experience the appetite-suppressing effects of Mounjaro until you reach a higher dose.
  3. Current eating habits: If you continue to eat ultra-processed foods rich in refined carbohydrates, sugar, and refined oils, you might still experience hunger between meals.
  4. Psychological health: Our mood and emotions can impact our cravings. If you’ve historically been an ‘emotional eater’ and find you reach for food when feeling sad or stressed, these cravings may still occur on Mounjaro.
  5. Other lifestyle factors: Our activity levels and sleeping patterns can influence our hunger. If we’re not sleeping well or exercising enough, we might still feel hungry on Mounjaro.

Mounjaro isn’t a magic pill

Weight-loss injections like Mounjaro are designed as additional tools for healthy lifestyle change and shouldn’t be considered lifelong medications.

Instead, they should be used to help you kickstart your weight-loss journey whilst you focus on building new, healthy habits.

Consider the use of antidepressants for people living with depression. They’re not designed to cure the condition. Instead, they’re designed to allow room for therapy to treat the condition’s underlying cause.

Mounjaro and Wegovy are similar. These medications can help silence food-related thoughts and also give you a boost of confidence with more immediate weight-loss results.

This helps to buy you the time and headspace to understand why your body may have struggled to lose weight previously, and to build new long-term healthy habits.

The core focus of our medication programmes are to calm down the feeling of food noise, lower your cravings, and to allow you to build healthier habits to keep the weight off for good.

The ultimate goal is to make losing weight feel second nature.

Second Nature’s medication-supported programmes

Second Nature has two medication-supported programmes: a Wegovy weight-loss programme and a Mounjaro weight-loss programme.

If you’ve made the decision to try Wegovy or Mounjaro (assuming you’re eligible), why should you choose Second Nature over other medication providers?

For peace of mind.

Second Nature has worked with the NHS for over 6 years, providing weight-loss programmes across the UK.

Whilst our Wegovy and Mounjaro weight-loss programmes are private and not currently used by the NHS, we’ve built the programmes focusing on scientific evidence, patient safety, and data security.

We hope that our 6+ years of working with the NHS and building a track record of trust and effective weight-loss results will give you peace of mind to give us a try.

Otherwise, if you’re currently on Mounjaro and still feeling hungry, keep reading as we look at three ways to optimise your results.

1) Be patient on Mounjaro to see results

Our first recommendation to optimise your results on Mounjaro is to be patient.

Tirzepatide, the drug in Mounjaro, is a long-acting medication that’s started at a lower dose to reduce the number and severity of side effects as it’s built up to a higher maintenance dose.

Tirzepatide can take 4-8 weeks to reach a level in the body we call a steady state. A steady state is when the drug’s levels in the body remain consistent rather than spiking and falling.

Based on data from randomised controlled trials, you can expect to lose up to 2% of your weight in a month on Mounjaro. After two months on Mounjaro, you could lose over 4%.

Interestingly, this initial weight loss is no different to other weight loss treatments or the impact of diet interventions on weight loss. The real impact of tirzepatide is seen beyond 3 months.

So, it can take up to 3 months before Mounjaro supports greater weight loss than is typically seen with traditional interventions like diet and exercise without medications.

During these earlier stages on Mounjaro, your hunger levels may still be higher than you’d like, which may rise and fall between meals.

However, if you’re able to persevere with Mounjaro and make some positive changes to your diet and lifestyle, you’ll be able to achieve your weight loss goals in the long term.

After 6 months, you’ll be on the maximum dose of Mounjaro at 15 mg, which is likely when you’ll experience the greatest reductions in hunger and appetite.

Key points

  • Mounjaro is a long-acting medication, and it can take up to 8 weeks before it reaches a steady state where hunger levels don’t rise and fall
  • If you’re able to persevere during the early months on Mounjaro and make positive changes to your diet and lifestyle, you’ll be able to reach your weight loss goals

2) Eat a diet based on whole foods while on Mounjaro

Ultra-processed foods are digested much quicker than whole foods, bypassing the signals our gut releases to the brain to lower hunger and appetite.

Research shows that when we consume ultra-processed foods, the hormones that signal to the brain to lower hunger and make us feel full are much lower than when we eat whole foods.

The effect (or lack thereof) of ultra-processed foods on our appetite is why we recommend consuming a diet rich in whole foods while on Mounjaro.

Here’s a list of food we recommend eating while on Mounjaro:

  • High-quality protein sources: Fish, meat, eggs, tofu, tempeh, yoghurt, cheese, and seafood.
  • Fat from whole foods: Meat, fish, eggs, dairy products (rich in calcium), nuts, seeds, avocado, and extra virgin olive oil.
  • High-fibre complex carbohydrates: Whole grains like quinoa and brown rice, sweet potato, white potatoes, pumpkin, legumes like lentils, chickpeas, beans, and butternut squash.
  • Fruits and vegetables: Take your pick, variety is key.
  • Make water your drink of choice: Hunger signals can indicate insufficient water intake.

Best diet while on Wegovy

Here’s a list of foods we recommend limiting while you’re on Mounjaro:

  • Ultra-processed foods: Most boxed cereals, supermarket bread and pastries, fast food, microwave meals, oven pizza, crisps, biscuits, fizzy drinks, and supermarket sandwiches.
  • Added sugar: Particularly from soft drinks
  • Refined carbohydrates: White pasta, white rice, and oats that aren’t steel-cut
  • Refined vegetable oils: Sunflower and vegetable

We also recommend eating three meals a day and including protein-rich snacks if necessary.

Having a consistent meal pattern can support the balance of our body’s hormone levels and help you feel fuller for longer.

Key points

  • Choosing a diet based on whole foods is best while on Mounjaro
  • Eating too many ultra-processed foods can adversely affect our hunger levels and lead to excess calorie intake
  • Eat three meals a day and enjoy protein-rich snacks if you need to

3) Find other ways to soothe challenging emotions

Our psychological health can influence our eating choices, and we may experience hunger or cravings for food beyond our physical requirements when stressed, lonely, or sad. This is commonly referred to as emotional eating.

Food provides us with great comfort, and research shows it lowers the intensity of challenging emotions and makes us feel better.

However, if we only use food to soothe ourselves during challenging times, it can adversely affect our health and hunger levels, as our brain will start associating these emotions with eating.

So, we must find alternative ways to soothe ourselves when feeling challenging emotions like stress, loneliness, or sadness.

Here are two things you can do to move away from emotional eating:

  1. Find acceptance: We’re always going to experience challenging emotions, and if we can accept them as part of our lives and daily mood changes, we’re more likely to move beyond them.
  2. Find alternative ways to soothe emotions: If we can find alternative behaviours or habits, known as ‘substitutions’, to soothe challenging emotions, we can move away from emotional eating. This might be taking a 5-minute walk, making herbal tea, or calling a friend.

Key points

  • Our emotions can impact our hunger levels and make us crave food beyond our physical needs
  • By finding acceptance and alternative ways to soothe emotions, we can move away from emotional eating

Take home message

Despite being a very effective medication to help lower hunger and support weight loss, we may still experience hunger on Mounjaro, particularly in the early stages of taking the medication.

However, suppose we can be patient, follow the treatment plan, eat a healthy diet based on whole foods, and move away from emotional eating. In that case, we’ll give ourselves the best opportunity to maximise our results on Mounjaro.
