As summer kicks off, many people will be well into a healthy regime, whether that’s following a new diet or a fitness plan.
With the rise in popularity of gruelling, high-intensity workouts, protein shakes have become a post-workout go-to for many. We’re constantly promised they’ll repair destroyed muscles and prevent the dreaded two-day burn.
It’s also no wonder gyms are promoting their fancy new shake bars, which come in at more than £7 ($9) a pop sometimes, as a nice little add-on to your already pricey gym class.
There’s no doubt that protein is an important part of post-exercise muscle recovery. But not everyone’s convinced we need to be consuming shakes in this way.
Before becoming a personal trainer, Max Lowery, 28, who created the 2 Meal Day intermittent fasting plan, was a professional sprinter for four years.
He told Business Insider why he has never taken a protein shake in his life – and doesn’t intend to.
Lowery believes protein shakes are unnecessary for about 90% of people.
“The only people who might benefit from them are vegans who aren’t being so careful with their diets – so it’s an easy way to get some protein – or elite athletes who are training twice a day six days a week,” he said.
“The average untrained person needs as little as 60-75g of protein and the average trained person who exercises three times a week needs 1.2g-2g per kilo of body weight. You can easily get enough protein from eating real food.
“In fact, too much protein can actually be broken down into sugars that create an insulin response which can facilitate fat storage. This is called gluconeogenesis.”
And he’s also unconvinced by what’s going into some of these powders.
“Lots of shakes are packed with artificial sweeteners like corn syrup solids, sucralose, and acesulfame potassium -companies use these because they are addictive and send a signal to the brain to keep drinking or eating without an off switch – even if they, themselves, don’t contain any calories.”
He added that a lot of whey protein comes from poor sources as well. “Most commercial whey powders are high-heat-treated, acid-flushed, and stripped of vital nutrients, creating an imbalanced, acidic ‘whey isolat,’ that’s frequently contaminated with synthetic additives, chemical detergents, and heavy metals,” he went on.
“It’s no wonder they have to use all these sweeteners to cover the taste.”
If you’re absolutely hell-bent on shakes, then Lowery says he recommends vegan proteins to his clients, such as Form Nutrition. “They’re generally healthier and take pride in the quality of their ingredients,” he said.
Regarding studies out there that support the consumption of protein shakes after a hardcore workout, Lowery says: “Like with many food products the companies funding studies have an interest in positive results. There have also been a few recent unbiased studies that suggest your protein consumption over the course of the day is what’s important, the emphasis that has been put on the hour after exercise is false.”
Protein shakes are part of the hard sell in fitness
Lowery has another issue with protein shakes: the way they are marketed.
“Sports drink manufacturers have been incredibly successful in convincing us that we need to consume copious amounts of their product in order to look and feel good. It’s a multi-million-pound industry with clever marketing and celebrity sports gurus promoting it.”
And the rise of Instagram fitness stars has only intensified things, he says.
“Influencers are being paid thousands to promote their products. They prey on people’s emotions. Unfortunately, people look at these influencers and believe that they look like that because they take protein shakes.
“This is untrue. They look like that because they train hard and eat well. There is no quick fix to getting fit and healthy, don’t waste your money consuming dust. Eat real food.”

- This list shows how many calories you burn while doing a number of popular sports, from running to swimming to rock climbing.
- But the best exercise to burn calories is one you like enough to do regularly.
- You can always make a sport more or less intense by pushing yourself harder or taking a breather.
There are a lot of great reasons to exercise – it’s the closest thing we have to a miracle drug. Depending on what you want to get out of it, you can see some results quickly, though others may take months.
But one of the most basic goals for a workout is to burn calories.
So what’s the best way to do that?
Most experts suggest picking a type of fitness that you enjoy enough to do regularly over time. But if you are deciding between a few different activities, you could pick the one that burns the most energy.
The Mayo Clinic, drawing on research published by the National Institutes of Health, ranks 36 popular forms of exercise based on their caloric impacts. We’ve ordered them from least to most intense, and listed the approximate calories burned in an hour for a 160- and a 200-pound person (in that order). According to the Centers for Disease Control and Prevention, American women weigh 168.5 pounds on average, compared with 195.7 pounds for the average American man.
We also calculated the values for several other sports, including soccer, rock climbing, and kayaking, based on NIH data, and included stats for a few additional popular activities.
39. Hatha yoga: 183 calories/hour | 228 calories/hour

Hatha yoga, a version of the practice centered on specific poses and mental exercises, sits at the bottom of this list, burning an average of about 183 calories an hour in a 160-pound person.

35. Bowling: 219 calories/hour | 273 calories/hour

Bowling can help you burn a few hundred calories an hour, but the alley snacks may counteract that.

Power yoga, or vinyasa, is a more movement-centered practice than hatha. More information about the different kinds of yoga and how beginners can get started can be found here.
28. Golfing (and carrying your clubs): 314 calories/hour | 391 calories/hour

If you golf, carrying your own clubs around the course makes a big difference. The calories a 200-pound person can expect to burn in an hour are roughly equal to the amount of time spent downhill skiing or taking a 3-1/2-mph walk.

At this pace, you’d run a mile in 7 minutes, 30 seconds.
What about other popular workouts?

It’s worth noting that all of these activities can be conducted at varying intensities, which means exact figures will vary based on energy input, body type, gender, age, and other factors. Additionally, exercise on its own doesn’t do much to make you lose weight. If you want to slim down, it’s best to talk to a doctor about what a healthy weight is for you and cut down on sugar and large portions.
It’s also impossible to include everything on this list – especially since some activities haven’t been validated by the data set used for this review.
But here are some rough calorie numbers for a few other ways people love to exercise:
Spinning classes: Attendees of the stationary-bike fitness classes can expect to burn 500 to 700 calories in an hour. This tracks closely with other data on stationary cycling.
Pilates: Pilates burns about as many calories as bowling or ballroom dancing – 219 calories an hour for a 160-pound person or 273 calories an hour for a 200-pound person.
Zumba: A Zumba-funded study conducted on young, healthy women found that a 39-minute Zumba class burns an average of about 360 calories.
