Protein for Weight Loss: How Much You Need and Simple Ways to Hit It
Protein helps control hunger, preserves muscle as you lose fat, and supports a steadier metabolism so results are easier to maintain. If you are using medical treatments such as Wegovy or Mounjaro, protein becomes even more important because your total food intake is often lower and every bite needs to count.
At The Florence Clinic, we see medication as a tool and lifestyle as the foundation. Getting protein right is one of the most reliable foundations you can build.
Why Protein Matters During Weight Loss
When you reduce calories, your body will draw on stored energy. Without enough protein, you can also lose muscle. Losing muscle makes it harder to keep weight off and can leave you feeling weaker.
Current expert guidance highlights protein as a top priority during anti-obesity treatment because it:
- Helps preserve lean mass
- Stabilises appetite
- Supports everyday function
A complementary paper on lifestyle and medical nutrition therapy for people using incretin-based medicines places protein near the top of the list, alongside fibre, fluids, and resistance training.
How Much Protein Do You Need?
There is no single perfect number for everyone, but helpful guidelines include:
General Targets
- A lower bound during active weight loss: 60–75 g per day
- Many people benefit from: 1.2–1.5 g per kg of body weight per day
Examples
- A person weighing 70 kg: Aim for roughly 85–105 g protein/day
- A person weighing 90 kg: Aim for roughly 110–140 g protein/day
These ranges are realistic and achievable with everyday food.
How to Distribute Protein Through the Day
Total intake is the first goal. Distribution is the second.
Make Protein the Priority at Each Meal
Many adults find three meals that each contribute meaningfully to the daily target work well. This approach:
- Improves fullness
- Supports recovery from activity
- Reduces the chance of finishing the day short of your goal
Protein and GLP-1 Treatments
GLP-1 medicines can reduce appetite, which makes it easier to stay in a calorie deficit but increases the risk of under-consuming protein.
Practical Steps
- Eat your protein foods first at each meal
- Then add vegetables, fibre-rich carbohydrates, and healthy fats
- Carry out regular checks for nutrient shortfalls
- Adjust your plan quickly if early fullness is reducing protein intake
Simple, Everyday Protein Sources
You do not need specialist products to reach these numbers.
Animal-Based Options
- Lean chicken or turkey
- Fish like salmon or cod
- Eggs
- Greek yogurt, cottage cheese, milk
Plant-Based Options
- Tofu, tempeh
- Lentils and beans
- Soy yogurts
- Legume + grain combinations
When Appetite Is Very Low
Small portions of high-protein foods help, such as:
- A scoop of whey in milk
- High-protein yogurt (20 g+ with low volume)
The goal is to meet your numbers consistently with foods you enjoy and tolerate.
Pair Protein with Strength Training
Protein provides the building blocks — your muscles also need a stimulus.
Two short resistance sessions each week can:
- Support muscle retention
- Improve strength
- Increase resilience
- Enhance results during fat loss
This does not require a gym. Bodyweight movements and resistance bands are perfectly effective starting points.
Is Higher Protein Safe for Everyone?
Higher protein intakes are safe for most healthy adults.
When to Seek Personalised Advice
Targets should be personalised if you have:
- Kidney disease
- Liver disease
- Or other medical considerations
If you have ever been advised to limit protein, obtain specific guidance before increasing intake.
How We Support Protein Targets at The Florence Clinic
In practice, we:
- Set a personal daily target based on weight, activity, and treatment
- Design meals so protein appears first on the plate
- Share choices that fit different appetites and cultures
- Check energy, sleep, and body composition regularly
- Adjust your plan as needed
If you are using Wegovy or Mounjaro, we pay special attention to protein intake because smaller portion sizes can easily push consumption below the level that protects muscle.
Putting It All Together
Choose a personal protein target using the ranges above.
Plan three meals that each contribute meaningfully to your total.
Eat protein first, then add colourful plants, whole grains, and healthy fats.
Add two short strength sessions each week and notice the difference.
Protein is not a fad — it is a reliable tool that helps you lose weight well.
Most adults benefit from 60–75 g per day, and many do best with 1.2–1.5 g per kg, especially during active weight loss or strength training.
Set your number, spread it across meals, and stay consistent. This is how you protect your muscles, manage hunger, and maintain results.
