How Much Protein Do You Need When Trying To Lose Weight?

Protein is an important part of a balanced diet, particularly when you are trying to lose weight. It can help you feel fuller after eating and provides the amino acids your body needs to maintain and repair muscle tissue. 

But how much protein do you actually need when you are trying to lose weight? For many adults, a useful general starting point is around 0.75g of protein per kilogram of body weight per day, based on the UK Reference Nutrient Intake. 

However, people who are actively losing weight, exercising regularly or following a higher-protein diet may choose to consume more than this. The right amount depends on factors including your body size, activity levels, overall diet and individual circumstances.

Why is protein important during weight loss?

When you reduce your calorie intake, your body needs to get its energy from somewhere. While the aim is to lose excess body fat, losing weight can also involve some loss of lean tissue.

Getting enough protein as part of a balanced, calorie-controlled diet can help support the maintenance of muscle. This is particularly relevant if you are losing weight gradually and including physical activity, especially resistance exercise, in your routine.

Protein can also be satisfying. Foods containing protein can help you feel fuller, which may make it easier to stick to a structured eating plan without feeling that you need to constantly snack.

How much protein should you eat?

There isn't one protein target that works for everyone. The UK Reference Nutrient Intake for adults is around 0.75g per kilogram of body weight per day.  

For example, someone weighing 70kg would need approximately 52.5g of protein per day based on this general reference.

However, higher protein intakes are often used in weight-management diets, particularly where calorie intake is reduced. Your individual needs can vary, so it is sensible to consider your overall diet rather than focusing on a single number.

If you are following a structured low-calorie diet, using meal replacement shakes or making significant changes to your diet, follow the nutritional guidance provided with the plan or products you are using.

What are good sources of protein?

You don't need to get all your protein from one type of food. A varied diet can provide protein from both animal and plant sources.

Useful options include:

• Eggs
• Chicken and turkey
• Fish
• Lean meat
• Greek yoghurt and other dairy products
• Cottage cheese
• Beans and lentils
• Tofu and other soya products
• Nuts and seeds
• Protein-rich meal replacement products

The best approach is to spread your protein intake across the day rather than trying to consume most of it in one meal.

For example, you could include a protein-rich breakfast, a balanced lunch and dinner containing a source of protein, with suitable snacks or meal replacements where needed.

Can meal replacement shakes help you get more protein?

For people who want a simple and convenient approach to weight loss, a high-protein meal replacement shake can make it easier to include a consistent amount of protein in your day.

A high-protein shake can be used as part of a structured meal replacement plan or alongside conventional meals, depending on the product and the plan you are following.

It's still important to look beyond protein alone. A suitable meal replacement should provide appropriate calories and a useful range of vitamins and minerals as part of a balanced diet.

How can you eat more protein when your appetite is low?

Some people find that their appetite is lower when they are trying to lose weight, which can make it harder to consume enough food and protein through conventional meals.

This is one situation where convenient options can be useful. A shake or bar can provide a portion of protein without requiring you to prepare and eat a large meal.

For anyone using weight-loss medication, nutritional needs and tolerances can vary. Meal replacement products can provide a convenient food option, but they should not be considered a substitute for personalised medical or dietary advice. 

If you have specific nutritional concerns, speak to a qualified healthcare professional or dietitian.

Make protein part of a simple routine

If you're trying to lose weight, you don't necessarily need to calculate every gram of protein you eat. Start by making sure each main meal contains a clear source of protein and consider convenient options when preparing food isn't practical.

A structured meal replacement plan can make this even simpler, particularly if you prefer having clear portions and predictable nutrition.
