GLP-1 medications such as Ozempic, Wegovy and Mounjaro have changed weight-loss care. For many people, they quiet appetite and make a calorie deficit possible. But whether you use one or not, the same things decide how you feel, how much muscle you keep and whether the weight stays off: what you eat and how you behave around food.

Medication helps; habits sustain

A medication can reduce hunger, but it cannot choose your meals, build your routines or manage stress for you. Studies of people who stop GLP-1 medications show that many regain a good part of the weight, which is why building habits while you are losing is so important.

The nutrition keys

• Protein at every meal to protect muscle and fullness. Use our protein calculator.
• Vegetables and fibre for volume, digestion and nutrients.
• Enough fluids, especially if appetite is low.
• Fewer ultra-processed foods and sugary drinks, replaced by simple, satisfying alternatives.

The behaviour keys

• Planning. Decide your meals and snacks ahead so the choice is already made.
• Environment. Keep supportive foods visible and tempting ones out of sight.
• Emotional eating. Name the trigger (stress, boredom, fatigue) and have a non-food response ready. See our page on the mental weight.
• Sleep and stress. Poor sleep and chronic stress raise cravings and make good choices harder.
• Movement. Daily walking plus strength training helps keep muscle and mood steady.
• Self-monitoring. Weigh in regularly, use the weight-loss forecast and track what works.

If you use a GLP-1 medication

Use the months on treatment to build the routines you will want afterwards: regular protein, planned meals, strength training and a plan for cravings. Talk to your prescriber about the long-term plan. Our GLP-1 nutrition guide explains how to eat well on treatment.

If you do not use medication

The same keys work without it. Slower progress is normal, and a structured plan with professional support makes it easier to stay motivated.

Frequently asked questions

Can I lose weight without a GLP-1 medication?

Yes. Many people lose weight and keep it off with a structured plan, protein, movement and behaviour support.

Will I regain weight if I stop the medication?

Regain is common when habits have not changed. Building routines while on treatment, and following up with a professional, lowers the risk.
