Why do people drink protein shakes?

I’m somewhat new to the dieting and health world. I’ve lost around 20 pounds with probably 25 to go. I’ve accomplished it by just following a three meal a day diet plan. Switched to whole grain and reduced alcohol.

But obviously there’s no denying everyone is obsessed with protein right now. And protein shakes. I jog for around 10 mins so assume my protein needs aren’t massive. And as a meat eater I am probably doing ok.

But can someone explain why a person would choose to have a protein shake over a chicken salad say. Or scrambled eggs?

My sister suggested I buy some as she saw some on offer but in my mind I prefer just to eat a meal as otherwise I would feel very hard done by and therefore much more likely to pig out.

Is it convenience?

Is it to do with muscles? As I know lifting is a lot more popular now

Do they keep you fuller for longer than a meal would? Just want to know if I’m missing a trick.

I drink them because I find the protein to be the least interesting bit of a meal (I like vegetables and carbs), so wouldn’t get enough otherwise. This was particularly the case when I was pregnant and couldn’t stomach most protein sources at all.

I drink them because I usually don’t eat breakfast or lunch. They offer a good amount of protein (46 grams in the one I buy) and I’ve noticed myself putting on more muscle now that my intake is higher. I don’t feel hungry until dinner, even after working and riding my horses. It’s extremely convenient.

Well I am just speaking from my own experience. So many recipes, especially breakfast ones, include a scoop of protein or if you google “healthy pancakes” invariable “protein pancakes” etc come up.

I was looking for muller rice yesterday in the supermarket as I had a craving and I saw they had ones with added protein. Was just curious why it seems to be popular right now

Well done on your weight loss. You’re obviously doing it right! Nothing has changed: eat real food, not too much, and move your body. The rest is people making money at the expense of your health and wallet.

My husband lifts weights, so he has a protein shake as well as his usual meals, not instead of. I'm not convinced he needs that much protein, but he doesn't look bad on it.

Jom222 · 24/11/2025 14:18

Its just the latest food craze, feel free to ignore until the next craze. Very few adults need more protein. This is a new way to separate us from our money.

Because influencers on social media are telling them to do so.

Have a look at the advice on Zoe or the Zoe podcasts - proper science based info. Zoe is run by Prof Tim Spector.

Theyre cheap, quick and low cal for the protein amount - usually 20g for 200kcal.

They taste horrible 'raw' but if you add things like frozen fruit (good for fibre), expresso and also linseed/chia seeds, they can be okay.

They keep me full - probably because they are slightly nauseating.

Holluschickie · 24/11/2025 14:17

The rest of my diet is non UPF too. My GP has actually told me I need more protein because of being veggie.

Ygfrhj · 24/11/2025 14:16

If you're trying to bulk up and working out a lot, but you also have a healthy diet, it can be hard to get in the amount of food you need to gain muscle or maintain weight. I used to have them for that reason when I was very into sports.

My husband loses weight easily and forgets to eat when stressed so he uses them to fill up.

BestWay · 24/11/2025 14:16

I have a protein drink every day regardless of whether I’m dieting or not. I have it for breakfast. I don’t fancy eating first thing and I really like the taste of the protein drink and I like being able to grab it and go. I then don’t feel hungry until after 1 or later. The rest of my diet is mostly non processed. Protein or diet drinks have improved a lot. I’m careful when I buy them and only get them when they are on sale.
I’m not saying it’s ideal but it works well for me. When I’m dieting I like the extra protein it gives me.

I use them because it means i don't have to go in the fridge and deal with food.

They're easy and the calories are counted.

They taste nice.

They fill me up.

Because i've spent money on them i feel more inclined to stick to the diet otherwise i've wasted the money.

They're easy to bung in my bag so i don't get ravenous while out shopping and come home and eat loads.

It's not obvious, it's absolutely deniable, far from everyone is obsessed, and obsessed is another exaggeration.

I think this sentence should read "but it seems that some people take protein shake adverts at face value".

There is no evidence that lots of people beyond the very elderly don’t get enough protein

there is a big push by certain industries to suggest that recommended protein suggestions are way too low but personally when there is big money involved I treat it with a huge pinch of salt

western diets are not short of protein but poeple
believe the hype

Edit to add the “Atkins diet” of decades ago was based around high protein as it fools you into feeling full for longer but the long term health damage was atrocious

Edited

The evidence was more nuanced from what I saw.
If you are trying to lose weight especially if you’ve got a fair bit to lose extra protein helps preserve muscle mass that’s why many of us on the GLP1 threads discuss protein intake coupled with weight bearing exercise.
Your ability to absorb and utilise dietary protein drops off in middle age so you need more protein per kg of body weight.

U less you have a disorder lentils may be carbs but they are slow release carbs and so kind of useful

unlike most of the ingredients in a protein shake

No. That’s literally why I have them - so I’m not hungry for ages.

Oh I assumed it would be as filling as a glass of milk. I tend not to be able to have soups as a meal as I’m hungry not long after.

May have to pick one up to see for myself.

Do they maintain energy levels? I often feel sluggish in the pm

Holluschickie · 24/11/2025 14:08

I am a vegetarian. Dont have them daily but I have one maybe twice a week as I am post menopause and need to lose weight. I also eat eggs, yoghurt, and tons of lentils but lentils are carb heavy.

I have had a bypass and really struggle to hit my protein goals with meat. I can manage eggs for breakfast but there is only so many eggs you can eat a day. I can’t stomach large amounts of meat so I have a 5 type collagen powder in my morning coffee and then a soup with unflavoured protein powder and bone broth, then an evening meal like shepherds pie. Snack is Greek yogurt with berries and chopped mixed nuts. But my portions are restricted to a tea cup size for evening, but meat I’m lucky of I can eat more than a matchbox size piece even if it’s shredded and in sauce. So protein shakes and powder really help me.

For the people who have them, are you not hungry within a couple of hours?

I am semi retired so have plenty of time to eat.

I tend to use them as loosely keto diet. Also, I get the chocolate (vegan pea) ones and have with soya milk. I use them to try and satisfy my sweet tooth and up my protein intake (although I eat meat). I do however work out a lot - i lead exercise classes and horse ride. Sometimes I can't face a whole meal but a protein shake keeps me going.

My DD eats them because she struggles to eat anything else (sensory issues). Yes, UPF, yes, sub optimal but she'll tolerate them so that's a win.

For some people getting the balance right between protein and fat as quite hard (e.g. if high cholesterol, and choosing to reduce fat) and protein shakes are often low fat and high protein.

MyDogHumpsThings · 24/11/2025 14:04

I’m not a big protein shake drinker, but very occasionally have them as a low-calorie filling alternative to food. Just laziness for me, in honesty. I didn’t realise until quite recently how bad they were, in terms of UPFs.

However, the other day I had a hankering for a large cauliflower cheese, which doesn’t have enough protein to qualify as a standalone meal in my opinion. I added some flavourless protein powder to the sauce and Bob was the proverbial uncle.
