If you’re like everyone else, you’re getting old! And as you get older, you may come to the bitter realization thatit becomes increasingly difficult to maintain and build muscle mass.
This is particularly true over the age of 40…
Let’s see why, after 40, you should adapt your protein consumption to continue building muscle effectively.
Forties, here is sarcopenia, your new friend!
As we age, the body undergoes changes that make it more difficult to maintain muscle mass.
One of the main phenomena responsible for this muscle loss is what is called sarcopenia. Ce natural process leads to a gradual decrease in muscle mass and strength from the age of 40 onwards.
This means that even if you continue to exercise regularly, your body has a harder time maintaining muscle, let alone building new one.
This phenomenon is due to several factors:
- Decrease in anabolic hormones like testosterone and growth hormone. These hormones are essential for protein synthesis and muscle repair.
- Reduced insulin sensitivity, which can affect how muscles use amino acids to repair and grow.
- Decreased ability to synthesize protein means your muscles become less efficient at turning the protein you consume into muscle tissue.
Why is more protein needed after 40?
To counteract these effects, it is crucial to increase your protein intake.
The amount of protein you consume daily has a direct impact on your ability to build muscle.
After 40 years, the muscle protein synthesis is less efficientmeaning your body needs more protein to compensate for this inefficiency.
You must therefore consume more to sufficiently stimulate muscle protein synthesis. Note that even if you exercise regularly, insufficient protein intake can lead to muscle breakdown, especially as sarcopenia progresses.
Furthermore, as he gets older, he becomes increasingly difficult to recover after training.
Consuming enough quality protein helps speed up muscle repair and minimize muscle soreness after exercise.
How much protein should you eat?
So, how much protein is ideal after 40? Recommendations vary, but for an adult over 40 looking to maintain or build muscle mass, it is often recommended to consume between 1.6 and 2.2 grams of protein per kilogram of body weight per day.
For example, if you weigh 80 kg, you should aim for a daily protein intake of between 128 and 176 grams.
It is also important to spread this intake throughout the day to maximize protein absorption and synthesis.
Protein quality: another key factor
Not all protein-rich foods are created equal. To optimize muscle building, you should favor complete protein sourcesthat is to say proteins containing all the essential amino acids.
Here are some of the best sources of protein to include in your diet:
- Lean meats: chicken, turkey, lean beef.
- Fish: salmon, tuna, mackerel.
- Eggs: a very complete source of protein.
- Dairy products: Greek yogurt, cottage cheese.
- Plant proteins: if you are vegetarian or vegan, be sure to combine different plant sources such as legumes, quinoa, or even chia seeds to obtain all the essential amino acids.
The importance of resistance training
If you really want to optimize your efforts to build muscle after 40, it is essential to incorporate resistance training into your routine.
Lift weights or use strength machines stimulates muscle protein synthesis, which is essential for maintaining and building muscle mass as you age.
However, it is important to note that training alone is not enough.
Without adequate protein intake, your efforts may not yield the desired results. By combining regular training with a protein-rich diet, you maximize your chances of maintaining and even increasing your muscle mass.
When to consume your proteins to maximize your muscle gains?
The timing of your protein intake can also play a crucial role in the effectiveness of muscle building after 40. It is recommended to consume proteins at strategic times of the day to promote recovery and muscle growth:
- At breakfast: after a long night of fasting, your muscles need protein to stop muscle breakdown and stimulate protein synthesis.
- Post-workout: Right after a weight training session, your muscles are particularly receptive to nutrients. Consuming protein within 30 to 60 minutes of your workout can help maximize muscle repair.
- Before bed: Consuming a small serving of protein before bed can help prevent muscle breakdown overnight and promote muscle repair.
Do protein supplements become a necessity after 40?
As you age, it may become more difficult to get enough protein from food alone.
Protein supplements can then be a practical solution to achieve your daily goals (but absolutely not obligatory).
You can then consider purchasing whey or casein proteins if you are unable to meet your quotas with your diet alone.
In short, remember that after 40 yearsprotein needs increase to maintain muscle mass and fight against sarcopenia. It is essential to consume enough protein throughout the day, favoring high-quality sources and combining this with regular resistance training.
By adjusting your diet and incorporating the right supplements where necessary, you can continue to build muscle and stay fit, even after your 40s.
If you want to maximize your gains, start monitoring your protein intake today and adapt your workout routine to meet the specific needs of your aging body.
