Knowing when to take protein powder can give you a very slight edge in reaching your fitness goals.
Contrary to what some supplement ads and Instagram influencers might claim, the timing of your protein intake isn't a make-or-break factor.
However, there are a few key moments when protein powder can play an even more important role.
Join me and find out more about the relationship between protein powders and timing for different goals.
When Is It Optimal To Consume Protein Shakes?
There is no universal solution regarding the best timing for protein shakes.
The best time to drink a protein shake depends on the goals you're aiming to achieve.
Whether you want to bulk up, sculpt those muscles, shed some pounds, or maintain your hard-earned gains, knowing when to drink it can make a difference.
So, let's explore the various strategies to find the perfect timing.
For Fat Loss
Numerous studies have confirmed the relationship between high-protein diet and weight loss.[1][2]
The timing of protein supplements consumption is more important when discussing weight loss than other purposes.
Are you wondering why? Consuming a protein shake promotes feelings of satiety, helping you to control cravings and overeating caused by a hunger hormone.[3]
That's why you can drink it throughout the day to lose weight, and it works both for males and females.
If you drink it in the morning, you will eat less for lunch and not resort to unhealthy snacks, so I usually advise overweight people to fit one protein shake into the schedule before 2 PM.
Also, you can drink it later in the afternoon to limit the amount of food for dinner or even as a substitute for dinner, even though I most often advise clients against using shakes as meal substitutes.
All in all, protein supplements are valuable allies in the fat loss journey. The ideal timing and how much protein you need mostly depend on your diet.
For Weight Gain
No, I don't mean muscle gain. I'll cover that in the next section, and now I'm talking specifically about weight gain.
Most healthy adults cannot understand that there are those who are failing to gain weight even if they eat significant amounts of food. However, since I'm an ectomorph, I can confirm that gaining muscle mass and weight, in general, is very challenging for that body type.[4]
In order to overcome the inability to gain weight and muscle mass, consume two scoops of protein powder daily.
You can make one shake with two scoops of powder, but it is better to evenly distribute protein intake. Thus, you will give your body a constant source of protein; plus, if you drink it with milk, you will increase your daily calorie intake because more milk equals more calories and more protein.
For Muscle Gain
It's not easy to build muscle mass and muscle strength if you are natty.
Muscle development requires a significant effort both in terms of regular, intense workout regimens and a suitable diet. To support muscle protein synthesis, you must consume sufficient protein.
In this context, consuming protein supplements around resistance training can be highly beneficial for muscle building. Having a protein shake within an hour before or after your strength training helps provide a readily available source of amino acids to fuel muscle repair and growth.
Nonetheless, nothing bad will happen if you are an hour or two late with your protein intake. Only overall daily intake counts, except if you are trying to win the world bodybuilder championship.
Don't let inexperienced coaches convince you that the anabolic window is a magical period that lasts about half an hour and that if you fail to drink a shake, all your efforts will be in vain. It has been proven that the anabolic window is more myth than truth.[5][6]
The most important thing is to try to consume at least 1 gram of protein per pound of body weight, and if you want to maximize muscle growth, get close to 1.5 grams of protein per pound of body weight in your protein daily intake.
For Maintaining Muscle Mass
Why would you change the winning strategy?
If you want to maintain muscle mass and healthy weight, it implies that you have reached the fitness level you want. I congratulate you on that; I know how difficult it is!
I tend to keep the same timing and amount of protein during the maintenance phase or through a period of inactivity due to injury. It's always best to use a protein supplement as a snack to prevent muscle loss.
Older adults should remember that regularly consuming protein shakes and protein-rich foods can slow down the age-related progressive loss of muscle mass, called sarcopenia.[7] A good variety of plant-based foods is also important.
For Performance & Recovery
Protein is an inefficient energy source, so the body rarely uses it for that purpose.
Why am I telling you this? To better understand why the timing of protein consumption is not crucial for performance.
For sports activities, the body needs quick energy sources, such as carbs, so it will not utilize a protein shake unless it contains a large amount of sugar (which I do not recommend).
The optimal time is when it suits you the most so that you feel good and energetic once you go out on the field or enter the gym.
Protein shakes are also valuable on non-workout days to support recovery. On those days, add the right protein powder to your oatmeal for breakfast or drink a protein shake as a snack to support ongoing recovery with enough protein.
Drinking Protein Shakes In The Morning
Drinking protein shakes for breakfast or first thing in the morning is a practice that has gained popularity among fitness enthusiasts and fanatics alike. It’s a convenient way to use protein powder to kickstart your morning and curb your appetite until lunch.
I understand why that is so popular because the shake is very convenient plus healthy (in most cases). Nevertheless, it can be a double-edged sword, so let's see the pros and cons of doing so.
Pros
Starting your day with a dose of pure whey protein is something your muscles will be happy about, no doubt.
Also, you feel full for longer, at least until a midday snack. A protein shake in the morning makes adhering to a calorie-controlled diet much easier.
When comparing starting the day with a whey protein shake versus indulging in a chocolate croissant and a cappuccino, it's clear that the protein shake takes the crown regarding nutritional benefits.
Cons
While there are benefits to drinking protein shakes in the morning, I think the cons outweigh the pros if you are serious about your fitness journey.
Relying solely on a protein shake for breakfast will result in a lack of dietary variety. [8]
Whole foods provide not just protein but also fats, carbs, minerals, and vitamins. You will miss all that if you consistently replace traditional meals with protein shakes.
Additionally, you may experience digestive discomfort when consuming protein shakes on an empty stomach. If this applies to you, it may be worth experimenting with having a small meal before.
If you're choosing between a protein shake and going to the bakery, I still vote for the protein shake, but keep in mind that you won't be able to maximize your performance that way.
Drinking Protein Shakes At Night
Drinking a protein shake before bed is often a good idea. It is an indispensable part of my diet routine whenever I want to put on a few more pounds of muscle or boost recovery after a 3 hour-long tennis match.
I would not recommend it if you are lactose intolerant, but even in that case, you can switch to other animal proteins or plant-based protein powders, such as pea protein and hemp protein. [9] It is best to go with unflavored protein when buying plant proteins to reduce calorie intake from added sugars.
Pros
One major benefit is providing your body with a slow-release source of amino acids throughout the night. This improves muscle recovery and growth of muscle tissue during the overnight fasting period, especially if you've had an intense weight-lifting workout earlier in the day.
Casein protein is superior to whey protein for this purpose.[10]
For those looking to maximize muscle gains, having a protein shake before bed is an effective strategy to increase overall protein and calorie intake.
It is also helpful for obese people who often get up during the night to eat. A protein shake before bed will probably prevent that.
Cons
My biggest concern regarding consuming protein powder close to bedtime is the potential sleep disruption due to digestive issues.
Listen to your body and assess how consuming a protein shake before bed affects your personal sleep quality.
A good night’s sleep is way more important than 20 grams of protein.
Taking Protein Powder Before Or After Workout
One of the most common questions of my clients is whether to drink shakes before or after a workout.
My answer is always the same - the most important thing is to drink it, and both times are advantageous.
Pre-workout protein intake helps create an anabolic environment, priming your body for the upcoming workout, but more research is needed to convince me that the difference is significant.
Following your workout, having another protein shake is equally crucial. This post-workout shake replenishes your amino acid stores, stimulates muscle protein synthesis, and aids in recovery and rebuilding.
This combination of pre-and post-workout protein intake improves the potential for weight gain and optimal muscle growth.
Protein synthesis happens over time, so you're still good to go as long as you have your shake within a few hours after your workout.
When it comes to weight loss, the focus should shift more toward controlling hunger and reducing overall food intake.
The number of protein shakes you should have daily depends on your protein needs, fitness goals, and overall health. Generally, aiming for 1-2 protein shakes a day, in addition to a well-balanced diet, can help support your fitness and nutrition targets. They mustn't replace whole food sources.
You can drink protein shakes as often as every day, but it is not mandatory. Overall daily protein requirements, activity level, specific goals, and meal plan should dictate the frequency of drinking protein shakes. If you struggle to meet your protein needs through whole foods alone, incorporating them into your daily routine can be beneficial.
Having a protein shake on an empty stomach is not harmful to your health, but the first meal of the day should be real food. Your body can absorb the essential amino acids from the shake effectively, yet it lacks other essential macronutrients. Save a shake for a snack.
Yes, you can take too much protein powder. That is unlikely to happen because you would have to drink numerous scoops of powder in a short period of time. Still, excessive total protein intake can strain your kidneys, cause side effects, and lead to other health issues.
When Should You Drink Protein Powder? (Our Verdict)
While timing can play a role, the most crucial factor is your overall daily protein intake.
You can benefit from drinking it before or after a workout, but also during any other part of the day. You're on the right track as long as you're meeting your protein requirements throughout the day.
So, focus on finding that balance and eating protein-rich foods. And if you have some specific goal, consult a dietician or a licensed personal trainer who can tell you how much protein powder you need.
