How much weight will I lose on weight loss drugs?
Robert Price | Last update: 26th May 2025
If you’ve recently started GLP-1 weight loss drugs (these are weight-loss treatments that help you feel full faster and eat less like Mounjaro and Wegovy), or you’re considering them, you might be wondering what your journey will look like. While these treatments can be highly effective, the process isn’t always linear. Here’s what you should know as you embark on your weight loss journey.

Understanding weight loss patterns
Weight loss drugs help us achieve steady weight loss over time. However, it’s important to remember that results can vary widely from person to person. In the first few weeks, many of us experience a noticeable drop in weight — often due to water loss as your body adjusts. After that, the pace of weight loss may slow down but remain consistent.
Top Tip:
Track your progress using more than just the scales. Measurements (waist, chest, upper legs), photos and how your clothes fit can reveal positive changes even when the scales don’t move downwards.
The reality of weight loss plateaus
Weight loss plateaus are a common part of the journey. These occur when our bodies adapt to a new lower weight and resists further changes. Plateaus can be frustrating but are completely normal.
- Why do they happen? Your metabolism may slow down as you lose weight, reducing the rate at which you burn calories.
- How to overcome them: Reassess your habits. Are you staying active? Eating the right foods? Sometimes small adjustments can reignite progress.
“I hit a plateau after losing my first 5kgs. I was expecting things to progress fast so it was annoying but I kept faith and concentrated on my other victories, like building up my exercise or feeling more comfortable in my clothes. This helped me stay focussed.”

Celebrate weight loss victories. Improved energy levels, better sleep, and improved mobility are all signs of progress.
Barriers to expect along the way
While weight loss drugs can reduce appetite and cravings, other barriers may still arise:
- Emotional Eating: Long-standing habits of turning to food for comfort can be tough to break.
- Social Pressures: Dining out or attending events might challenge your new eating patterns and reduced alcohol intake.
- Side Effects: Some users experience nausea or other side effects, which can impact day-to-day routines.
Top Tip:
Plan ahead for social situations. Eat a small, protein-rich meal beforehand to avoid overindulging and take your own snacks and non-alcoholic drinks if needed.
Setting realistic expectations
Ignore what you read in the press! Weight loss drugs are not a quick fix. On average, users lose about 10-15% of their body weight over several months. While this is significant, it’s crucial to approach the journey with patience and a long-term mindset.
- Consistency is key: Stick to your treatment plan and pair it with healthy habits like exercise and healthy eating.
- Avoid comparisons: Everyone’s journey is unique, so focus on your own progress rather than everyone else’s.
Top Tip:
Set small, achievable goals along the way. Each milestone, no matter how small, is a step closer to your overall goal.
The importance of support
A strong support system can make a world of difference. Whether it’s friends, family, or the SlimrChat community, having people to share your journey with can keep you motivated.
