Morning workout without breakfast is said to be bad

Sat 22 Oct, 2022 05:59 pm
Hello everyone, I have read somewhere that doing workout just after waking up without at least taking a breakfast may be bad, and lead to muscle loss.

I think that was because the effect of a hormone named cortisol, which is at it highest along with testosterone after waking up morning (from a sleep). I forgot how the process was, but in the scientific article I read which was based on a study, Cortisol somehow led to significant muscle loss overtime.

A way to prevent that would be to eat something before morning workout.
How much of that is true? And if it is, how much of food is enough? Taking sometime to ready food then waiting for digestion may remove a lot of my drive to train morning. By that I mean 30 - 60 mins jog + some exercises usually with an empty stomach. Would buying a light snack in the way suffice?

I hope for serious answers, rather than answers or cheering based on feeling to not let a person gives up a good practice that you like. I also love workout, but want to keep it efficient.

@messiah of culture,
depends on how you time it. Working out in general, from running, jogging, jumping jacks, pull out, etc is not bad at all, I assume you strech a bit. I see tons of joggers, they get up out of bed do a run, come back for breakfast and then go to work/school.

The answer is no. Your body needs to rejuvenate from any loss of calories. Not Break-fast. While fasting your body has nutrients to use.


When I lost weight, I was only thinking about my diet needs and doing my walks. It worked. Now talking about gaining muscule mass or maintaining it via exercise and a proper matching diet is another story all together.

Exercising before breakfast may be most healthful choice

Some studies suggest that the effectiveness of exercise may be tied to when a person eats.

However, it is rarely possible to translate findings from studies in lean people to those with obesity.

So, scientists from the Universities of Bath and Birmingham, both in the United Kingdom, set out to see if meal and exercise timing had a similar link in people with overweight or obesity.

Having obesity and living a relatively sedentary life can lead to an increased risk of cardiovascular disease.

This is because insulin sensitivity is reduced, and hyperinsulinemia — a condition characterized by excess insulin levels — is increased.

Finding a way to prevent these insulin-related effects could potentially prove to be life-saving.

‘Profound’ benefits

The study, which now appears in the Journal of Clinical Endocrinology and Metabolism, aimed to examine how exercising before and after eating affected muscle fat stores and insulin response. It was the first to look at this relationship in people with overweight or obesity.

The experiment, which lasted for 6 weeks, involved 30 men the researchers categorized as either overweight or obese.

The team split these men into three groups:

• one that ate breakfast before exercising
• one that ate breakfast after exercising
• one that made no lifestyle alterations

“Our results suggest that changing the timing of when you eat in relation to when you exercise can bring about profound and positive changes to your overall health,” says Dr. Javier Gonzalez, from the University of Bath’s Department for Health.

A greater burn

Participants who exercised before breakfast burned twice as much fat as those who exercised after eating the same meal.

There is a simple reason for this: When people fast overnight, they have lower insulin levels during exercise, allowing their body to use up more fat.

“Importantly, while this didn’t have any effect on weight loss, it did dramatically improve their overall health,” notes Dr. Gonzalez.

The muscles of those who exercised before breakfast responded better to insulin, better controlling blood sugar levels in the body.

Dr. Gonzalez says that this effect is “all the more remarkable, given that both exercise groups lost a similar amount of weight and both gained a similar amount of fitness.”

“The only difference was the timing of the food intake,” he adds.

The muscles of those in the group who exercised before breakfast also exhibited bigger increases in certain proteins — especially those responsible for delivering glucose to the muscles.

Even more notable was the fact that those who ate breakfast before exercising were no better off in terms of insulin response after eating than the control group.

Future focus

“This work suggests that performing exercise in the overnight-fasted state can increase the health benefits of exercise for individuals, without changing the intensity, duration, or perception of their effort,” states study co-author Dr. Gareth Wallis, from the University of Birmingham.

These particular findings are sex-specific, as the researchers only worked with men. Therefore, further studies will need to replicate the conditions in women to see if they, too, benefit from exercising before breakfast.

The breakfast that the participants consumed was high in carbohydrates, so future research may also need to examine whether low carb meals produce the same effects.

Longer studies will also need to take place before researchers can form any solid conclusions.

However, fasting overnight and exercising before breakfast could be the key to increasing the effectiveness of exercise in people with overweight or obesity.

I'd prefer breakfast in bed, sans the "work out". No pain, no problem.

@bobsal u1553115,
I concur! Ack to workouts. Was thinking of getting a rowing machine. For a second.

I know someone with a treadmill. She says it's a great place to hang clothes.

For a full second? You know, it's better not to dwell on this sort of thing.

Pro tip: If there is a TV in the room, one could use a treadmill to walk a dog or three-year-old baby sit charge. You should see the legs on my Jack Russell - and I never missed a Bay Watch re-run. My nephew apparently tore a couple of ligaments. I blame my sister's husband's bad genes.

@bobsal u1553115,
Wait - you put your nephew on the treadmill and he tore ligaments? How old was he - did you say 3? You're a menace, bobs!

@bobsal u1553115,
Nah! I don't need no treadmill. I've got an upright vacuum cleaner to hang my clothes on.

Either that or reacting to Baywatch, you know how some people get about Pamela Anderson.

If you were fairly well fed the day before, then I guess a light jog or short brisk walk in the morning before breakfast is okay.

But, if you're doing heavy gym workout with weights, I think breakfast first would be better.

Or you could change your exercise time to afternoon or later.
