A new study tracking more than 73,000 adults has challenged the long-standing belief that one minute of hard exercise equals two minutes of easier movement. The real numbers paint a very different picture and here’s what I have understood from the study.

The Old Rule Needs Updating

For years, health authorities have promoted a straightforward exchange: can’t manage 75 minutes of hard activity each week? Just do 150 minutes of gentler movement instead. This two-for-one swap made sense because intense activities burn about double the energy of gentler ones.

But this exchange rate came largely from people filling out forms about their exercise habits, not from tracking actual movement. When scientists used devices to monitor how people really move, they discovered something else entirely.

What the Numbers Actually Show

Researchers followed participants for roughly eight years, tracking outcomes such as mortality, cardiovascular events, diabetes, and cancer. What they found: one minute of hard activity equals somewhere between 4 and 9 minutes of moderate movement, depending on which health benefit you’re measuring.

To lower the risk of early mortality, one minute of running or hard cycling matches about four minutes of brisk walking. For cardiovascular protection, the exchange stretches to nearly eight-to-one. For type 2 diabetes, it’s closer to nine-to-one. The exact number shifts with the specific health outcome—but across the board, the real ratios are far steeper than the old 1:2 rule.

Gentle activity—slow walking, light housework—lags even further behind. Depending on the condition being measured, you’d need somewhere between dozens to over a hundred minutes of gentle movement to match what one minute of intense effort delivers. And for several health outcomes, increasing gentle activity didn’t show strong or consistent protection in the first place.

Exercise Intensity Matters

These figures tell us something significant: hard exercise is considerably more effective per unit of time than anyone realized. If your schedule is tight, brief periods of effort deliver more protection than earlier estimates suggested.

But what I find worth noting is that the researchers aren’t telling everyone to become endurance athletes. They found that even small amounts of vigorous activity—accumulated over time, a minute here and a minute there—add up meaningfully.

The Limits of Gentle Movement

The study revealed that gentle activity, while far better than being sedentary, has its limits. It doesn’t provide the same disease protection that moderate or hard activity offers, even when the total time spent doing it is very high.

Does this mean your evening walks are useless? No, but it does mean that if you’re aiming for the strongest long-term protection against major diseases, you’ll need to occasionally nudge yourself into a higher intensity.

What This Means for Your Wearable Devices

Most fitness trackers already award different scores to different movement intensities. But many of these systems are still built on older, questionnaire-derived assumptions about how intensity translates into health benefits.

This new evidence suggests those calculations may need revision. If you’re someone who monitors daily steps or activity points, it might be worth paying a bit more attention to effort level, not just quantity. A brief burst of hard work could be worth far more than you imagined.

The Research Details

The study examined adults between ages 40 and 69 in the UK. Scientists excluded people who already had the conditions being measured and waited a full year before counting any new health issues to avoid confusing cause and effect.

What strikes me as significant is that this work used direct tracking, not recall or guesswork. Participants wore devices that recorded their movement continuously in brief intervals. This degree of accuracy wasn’t available with paper surveys.

It’s worth noting that the findings show associations over several years; they don’t prove causation. But with such a large sample and objective measurement, the patterns seem compelling.

My Conclusion: It’s Time to Tweak Your Workouts

You don’t need to quit your walks. But if you’re walking for health improvements, consider raising your speed now and then. Find some inclines. Add a short jog. These minor adjustments may deliver benefits far beyond the extra effort involved.

The study doesn’t claim hard exercise is superior in every possible way. It simply shows that intensity matters more than we understood—and that even small doses, built up over time, can produce substantial results.

The research appeared in Nature Communications and examined 73,485 participants monitored for approximately eight years.

1. What is the best time to do cardio?

One of the great things about cardiovascular exercises is that it can be done at any time of the day. There’s cardio for each part of the day depending on its intensity. I’d usually suggest doing it whenever you think you feel energetic enough. Mornings are ideal for intense cardio such as running and sprinting. Even cardio done on machines are best done in the morning.

Mornings are great for cardio; evenings are great for walks

Mornings are great in terms of convenience but that doesn’t mean one cannot do cardio exercises later in the day if time permits. Our metabolism tends to peak around the afternoon. So fasting till noon and doing some cardio on an empty stomach is a potent way to go after that stubborn fat. For the evenings, a simple walk should be the best. Walking helps the body relax while you still burn calories. This makes walking unique as all other exercises create a stress response in the body. Try to avoid any kind of stress during the evenings as it could make it harder for you to fall asleep.

2. Should I do cardio before or after weights?

This is one of the most commonly asked cardio question. And the clear answer: cardio should always be done after weights. This is because weight training won’t hinder your cardio workout but a cardio session before weight training can reduce your performance in the gym.

Do cardio and weights on separate days

If you are worried about maintaining a certain level of performance even during your cardio sessions, it’s best to do weights and cardio on separate days. If you do decide to do them together, make sure there’s at least a 4-hour gap between sessions. Light cardio can be done immediately post workout. In fact, light cardio post workout enhances recovery. A short pre-workout cardio session can be used as a warm-up but it cannot be considered a workout in itself.

3. When is cardio most effective — morning or evening?

As mentioned in the first point, cardio is most effective on an empty stomach — it not only helps performance but also improves the body’s ability to use fat for fuel. Plus, it’s easier to do fasted cardio in the morning. If you can continue fasting till noon, do a 30-minute session before breaking the fast. This will dramatically help you achieve fat adaptation as the body will be in a deeper fasted state in the afternoon. Doing some physical activity in this condition forces the body to use fat, something it gets better at doing until one day it runs on fat effortlessly.

Sprinting is best done in the evenings — but avoid anything too close to bedtime

Let me repeat: cardio is effective regardless of when its done even though there are times in the day when you get more benefits from it. Performance-based cardio like sprints are best done in the evening as body temperature naturally rises in the evening. Strength and speed tend to peak in the evening hours. Even though these differences exist, cardio can be done at anytime. The important part is to get it done. Also, evening workouts should be avoided in general if maintaining a healthy circadian rhythm is a priority.

4. Should I eat before starting cardio or do it in a fasted state?

Fasted cardio — having an empty stomach during cardio — is ideal if you are aiming for weight loss. If fasted cardio is something you’re not comfortable with, then a light meal consisting of a fruit should suffice. Have some coconut water, a few berries or an apple about 30 minutes before starting your cardio workout. These can be also had immediately after the workout. The advantage of fruits is that they’re easy to digest.

Digestion and workout performance

Avoid foods that take time to digest like eggs, meat, etc. You can have these a short while after your cardio workout. If you must have them before your workout, then make sure you maintain a gap of at least 2-4 hours between your meal and the workout as digestion can hinder workout performance and vice versa — working out can hinder the digestive process.

5. Is cardio the same as HIIT? Which is better?

HIIT stands for High Intensity Interval Training. All HIIT is cardio but all cardio is not HIIT. HIIT requires you to perform a high intensity exercise for a short duration of time (10-60 secs) followed by an interval of rest. After the rest interval the intense activity is repeated. A perfect example would be 100 meter sprints, 6-10 times. Each sprints would last around 12-14 seconds.

Both HIIT and low intensity cardio have pros and cons

HIIT improves cardiovascular health and also improves fat loss in the long run. It also gives a boost in energy levels due to its effect on adrenaline. However, HIIT is not the best way to improve endurance. Regular cardio (called LISS — Low Intensity Steady State cardio) allows you to work at a lower intensity for a longer duration of time. Someone who is aiming to improve their ability to carry out an activity for longer will benefit more from LISS. A drawback of LISS is that because it is low intensity, it doesn’t lead to the same hormonal boost as HIIT. On the other hand, the disadvantage of HIIT is that it’s taxing to recover from, since it involves maximal or close to maximal effort. Either way, both benefit your overall wellbeing.

But how much is too much? Nutritionist John Berardi says that, “For an average person, any meal over 750kcal (not including pre- and post-workout nutrition) results in fat storage”. I don’t agree completely, as for an athlete it would vary greatly and would also depend on the ratio of fats, proteins and carbohydrates in the meal. A high protein meal may not get readily converted to fats as a high carb meal. However, when an average person eats 500+ calories from a candy snack bar, it is going to lead to fat gain. What’s worse, while we know how to stop it, we are still helpless.

Tips to deal with binge eating

Here are some simple tips to help you overcome the damage of binge eating:-

1. Treadmill counters are misleading

Many people I know compare the calories they burn on a treadmill or cross trainer with the calories they consumed in their meals. This is not a sound strategy. Firstly, on a treadmill, the calories shown include your BMR [the calories you burn at rest]. Say your body burns 2400kcal/day i.e. 100 kcal/hr. These calories are burnt by your body just to maintain your normal body functions. So if you run for an hour on the treadmill, the treadmill will show that you have burnt around 500kcal. But this 500kcal is including your BMR [basal metabolic rate]. So actual calories burnt would be 500 – 100 = 400kcal. Now a kilo of fat has around 7000kcal. At this rate, you need to run for over 17 days at the same intensity every day to burn just a kilo of fat—that too if your intake of calories is equal to your calorie output. This is why weight training and HIIT [high intensity interval training] are the best forms of exercises to target fat loss.

2. Make use of your “anabolic window”

After a hard and intense workout session, your metabolism sky rockets. Your body is like a furnace ready to burn whatever you put in it. This furnace is at its hottest for 45 minutes post workout, also called the “anabolic window”. When you know you are going to a party or will be gorging on foods that are likely to be unhealthy and high in sugar and full of empty calories, then working out before that meal is the best way to offset the negative effects of that meal. Though the 45 min window is the optimal time, the furnace is hot enough to burn your cheat foods even three hours after of your workout.

If for whatever reasons it is not possible to workout before you eat this meal then another way is to increase your exercise volume and intensity for a week before and after the binge day. Now the exercise I am talking about are intense weight training sessions and HIIT workouts, not leisurely strolls on the treadmill or pleasant rides on the cross trainer.

3. Eat before bingeing

It happens with all of us sometimes where we eat something just before our meals and then don’t feel hungry enough to have our main meal. This is a simple trick that dieticians refer to as the “Second Meal Effect”. Having something just before the main meal or an hour or so before it, would suppress hunger which automatically make you eat less of your cheat meal. The best bet is a big salad plate or a high protein, low glycaemic index food an hour before the main binge meal.

4. Cleanse after indulging

If you have eaten more than you should have and now need to detox, here’s an excellent way to do it. At night before sleep take two tablespoon of isabgol or Psyllium seed husks with three glasses of water. In the morning, have three glasses of water again as soon as you wake up. After you have emptied your bowels, add two capful of bitter gourd [karela] and gooseberry [amla] juice, each in less than half a glass of water and drink it. This will help stabilise your insulin levels and also provide you with powerful antioxidants. Thereafter, have a cup of green tea with lemon or 500mg vitamin C. Work out hard and eat clean that day and the next.

Remember, these techniques only help overcome the side effects of occasional binge eating. Do not make this a regular way of life.
