Energy bars, for the first time took off in the market in 1980s. This was first marketed as a "workout fuel" for athletes. Then, followed the advertising of the cars as something that also helps with weight loss. Now, they are not only something that only can be seen in gyms, but have made it to the mainstream. They are available in almost everywhere, in snack aisle of a gas station, supermarket, and even drugstores. As per a market research agency Mintel, around 40% of people say they eat an energy bar one a few time a week.

The way it has been marketed, and packaged make you seem like it is good for you. However, it may not be the case with most of them. In fact, even with the bars that claim to have high protein, are nothing, but just candy bars. So, how to know which one is good for you?

What are "Energy" bars?

There are many studies that reveal that there is no one special ingredient in these bars that works as an energy booster. Energy usually means calorie, which is measured in how much food or a drink fuels the body. As per experts, calories come from many sources including carbohydrates, protein and fat. However, for your body, it is easier to break down carbs faster than protein or fats. Thus, all carbs are converted to glucose, which is a sugar that enters the bloodstream and is used by cells for energy.

In fact, even in carbs, sugar and white flour is broken fastest of all. This could be helpful if you perform a demanding activity, such as running a marathon, as it can deplete your cells existing glucose. This is why eating a quickly digested carb, like an energy bar, can replenish them and gives you a little push to keep you going.

However, not everyone needs this push for a day-to-day life. Simple carbs also make your sugar levels rise rapidly, but it also falls back down just as quickly. This is because your body pumps out insulin to sweep the glucose into cells. This sugar crash can in fact, make you feel tired and hungry all the time. In such a case, what you body really needs is sustained energy that only comes from carbs combined with fiber, protein and fat. These slowly releases glucose into your bloodstream and keep the blood sugar levels steadier.

What's good And What's Not?

There are bars that combines a combination of carb, fiber, protein and fat, but not all of them use wholesome ingredients. For a healthier pick, always look for ingredients which uses unprocessed foods and whole grains like nuts, seeds, and dried fruit. These nutrients are usually more nutrient packed than the ones that are processed.

For grain-based bar, check for whole grains like oats or quinoa. Whole grains also reduce inflammation and harmful LDL cholesterol which protects the heart. As per a 2016 BMJ study, three servings a day could also reduce the risk of heart diseases by 22%.

In terms of what to avoid, you can look out for:

Too Many Calories: If you are someone who exercises a lot, then you can go for a 200 to 400 calorie bar. If you are not someone who exercises a lot, then such a high calorie rate could lead to weight gain.

Added Sugar: There is rarely any need to say why it is harmful for health. As per the American Heart Association, 25 grams is the recommended daily added-sugar threshold for women and 36 grams for men. Too much added sugar could lead to weight gain, type 2 diabetes and heart problems. In an "energy" bar, the natural sources of added sugars can be concentrated fruit juices and honey, which are not the better options than sugar or syrups.

Even if you bar says zero added sugar, make sure to read it correctly, as some of them use artificial sweeteners or dried fruits.

Processed Protein: While many think protein is great for building muscles and losing weight, not always does protein help, especially if the protein is processed. If in a bar, the source of protein is from protein powder, then it is not the best thing to choose. Always go for whole food proteins such as eggs, nuts or seeds. The daily recommendation is 0.36 grams per pound of body weight or 54 grams for a 150 pound person.

Processed Fiber: The recommended fiber intake is 28 grams daily, but most Americans also do not get this. Here too, read the label to see if your fiber comes from whole grains, nuts and fruits, and not from processed fibers like chicory root or inulin.

With growing awareness of how the female body changes each month, and the help of apps that make tracking easier, more women are beginning to understand how to live in sync with their cycles. According to Dr. Uma Shankar Sharma, Medical-In-Charge at Kailash Institute of Naturopathy, Ayurveda, and Yoga, what you eat during each phase of your menstrual cycle has a major impact on your hormones, energy, and mood.

What Are the Different Phases of the Menstrual Cycle?

Though biology books often describe a 28-day cycle, in reality, most women fall anywhere between 23 and 35 days. Within that span, the body passes through four phases: menstrual, follicular, ovulatory, and luteal. Each phase involves different hormonal changes and physical shifts that influence how you feel and function.

Four Phases of the Menstrual Cycle

The menstrual cycle begins with the menstrual phase, when the uterine lining is shed as bleeding. Next comes the follicular phase, when the body prepares an egg for release. During the ovulatory phase, a mature egg is released, and in the luteal phase, the uterus thickens in anticipation of pregnancy. If conception does not occur, the cycle restarts, as per Cleveland Clinic.

What to Eat During Every Phase of Your Menstrual Cycle

Food choices play a key role in maintaining hormonal balance, energy, and overall wellness. Dr. Sharma explains that Ayurveda recommends eating according to the body’s changing doshas, Vata, Pitta, and Kapha, throughout the month. Aligning your diet with these shifts can ease cramps, bloating, and fatigue, while helping restore nutrients lost during menstruation.

1. Menstrual Phase (Days 1–4)

At the start of your period, Vata dosha is heightened, and your body needs warmth and comfort. Dr Sharma suggests choosing simple, nourishing meals like steamed khichdi (made with moong dal and rice), warm porridge with ghee, and lightly cooked leafy greens. Gentle spices such as cumin, coriander, fennel, and ginger aid digestion, while ghee or sesame oil supports nutrient absorption. Avoid cold, raw, or fried foods, which can worsen pain and slow digestion. A warm cup of ginger tea can help soothe cramps and ease bloating.

2. Follicular or Postmenstrual Phase (Days 5–14)

As your energy returns, Kapha dosha rises. Focus on lighter, fresh meals that recharge your system, think fresh fruit, steamed vegetables, whole grains like millet, barley, or quinoa, and soft-cooked lentils. Dr Sharma says, “Soaked nuts and seeds provide essential minerals. Mild spices like turmeric, coriander, and ginger help keep digestion active and support nutrient absorption during this rejuvenating stage.”

3. Ovulatory Phase (Days 14–17)

During ovulation, Pitta dosha dominates, and your body functions at its most active. Cooling and hydrating foods are best during this time. Dr Sharma suggests eating fresh fruits such as watermelon and cucumber, drinking coconut water or diluted juices, and including sprouts and plant-based proteins like tofu or paneer. Avoid spicy, oily, or sour foods that can increase internal heat or irritate digestion.

4. Luteal/Pre-Menstrual Phase (Days 18–28)

As Pitta remains strong and Vata begins to rise again, your body benefits from grounding, nourishing meals that help calm premenstrual discomfort. Complex carbohydrates such as sweet potato, squash, oats, and cooked greens can support stable energy levels. Foods rich in magnesium, like bananas, seeds, nuts, and dark chocolate, can help ease cramps, bloating, and mood swings. Staying hydrated, sipping herbal teas, and including healthy fats throughout the month help maintain a steady, balanced cycle.

When it comes to eating, it is very easy to overdo it and cause problems for your health. Eating too much food is not just about gaining weight, but it can cause lot of issues for your metabolism as well as cause harmful reactions. According to the MD Anderson Cancer Center, overeating can cause a reaction known as heartburn, where the acid that breaks down your food gets pushed up towards your esophagus. Other problems that may arise could be bloating, organ strain, abdominal discomfort, etc.

All of these issues could be avoided if one controls one's eating habits. However, can you change the way you eat and train your body to avoid overeating? According to Dr Sudhir Kumar, Hyderabad-based neurologist, you can.

10 Habits That Can Help You Avoid Overeating

In a recent post on social media platform X, Dr Sudhir listed 10 ways one can teach one's body to avoid overeating and protecting their metabolism.

Tweak Your Eating Space

You can trick your brain into eating less by changing your environment. Try using smaller plates and bowls—it makes smaller portions look more satisfying. Keep food out of sight; if you don't see it, you won't think about snacking impulsively. Also, keep serving dishes in the kitchen, not on the dinner table, to make it harder to grab second helpings.

Slow Down How You Eat

Give your brain time to catch up with your stomach. Eat slowly and chew your food well. Make a point of putting your fork or spoon down between bites. It takes your brain about 15 to 20 minutes to register that you're full, so slowing down gives this "fullness signal" time to register, helping you eat less overall.

Handle Social Eating Smartly

When you're eating with friends or family, you tend to eat more because meals last longer. To manage this, serve yourself a fixed portion before you sit down. Then, focus on the conversation instead of reaching for more food. If you stay at the table for a long time, sip on water instead of continuing to eat.

Build Your Meal Strategically

Eat your food in a specific order to help manage your blood sugar and keep you feeling full longer. Start with vegetables or salad, then move to protein, and finish with carbohydrates. This order prevents rapid sugar spikes and avoids the quick hunger that comes after eating simple carbs like bread or sweets first.

Prioritize Filling Foods

Make sure every meal includes a source of protein like eggs, pulses, yogurt, or fish, and fibre from vegetables, whole grains, and fruits. Both protein and fibre are excellent at increasing the feeling of fullness, which naturally cuts down your total calorie intake. Try to limit high-calorie, non-filling items like refined carbs and processed snacks.

Don't Ignore Sleep and Stress

Poor sleep and high stress directly affect your hunger. Aim for 7–8 hours of sleep nightly, because lack of sleep increases the hormone that makes you hungry, called ghrelin, and lowers the hormone that tells you that you're full which is called leptin. Manage stress with things like walking, deep breathing, or meditation. Chronic stress often leads to emotional eating and intense cravings.

Move Your Body More

Moving doesn't just mean a full workout. Take a short walk (10–15 minutes) after meals; this is a great way to stabilize your blood sugar and help digestion. Avoid sitting still for hours; taking short standing breaks and small movements throughout the day actually improves how your body uses insulin.

Use Water to Your Advantage

Drinking water can subtly help you eat less. Drink a glass of water before meals; this can modestly reduce how much food you eat. Always avoid sugary drinks and juices, as they add lots of calories without making you feel full.

Focus Only on Eating

Sit down and eat without screens, no TV, phone, or laptop. This helps you pay attention to your body's signals of hunger and fullness. Before and after you eat, quickly rate your hunger on a scale where 1 is starving, and 10 is painfully full. Aim to stop when you feel comfortably satisfied which is around a 7.

Plan Your Portions

Don't eat snacks straight out of a large bag; pre-portion them into small containers. Use smaller utensils, like a teaspoon for desserts, to naturally slow down your eating speed. Finally, don't skip meals! Getting extremely hungry almost always causes you to overeat later in the day.

The debate between what is more important or the driving factor behind the rising cases of obesity may be solved now. Thanks to the new research led by over 50 institutions across 19 countries that revealed it is diet, or in simpler words, the calorie consumption and not the lack of physical activity that is a dominant factor driving obesity.

The study is published in the Proceedings of the National Academy of Sciences (PNAS). The study is more so important because it challenges the belief that sedentary lifestyle is the primary cause of driving the obesity rates high.

What Did The Study Find?

The study found that higher calorie intake actually plays a much larger role in obesity than reduced physical activity. Despite decades of research into the causes of the obesity crisis, the relative importance of diet versus physical activity has remained uncertain,” said Herman Pontzer, professor of evolutionary anthropology and global health at Duke University, and one of the study’s authors. “The IAEA’s Doubly Labelled Water Database has allowed us to finally test these ideas on a global scale and bring clarity to this major public health challenge.”

What Is IAEA? Why Does It Matter?

IAEA stands for the International Atomic Energy Agency. The research recently published used IAEA's Doubly Labelled Water (DLW) Database, which is one of the world's largest collections of energy expenditure data. The dataset was able to provide the researchers a look into the balance between energy intake and energy output across the populations and economies.

Is Global Obesity On The Rise?

In 2022, nearly 1 in 8 people worldwide were living with obesity. This is a number that has doubled more in adults and quadrupled among adolescents in the past three decades. Obesity also increases risk of many chronic illnesses and diseases, including diabetes, cardiovascular disease, and also certain cancers.

While industrialized societies see soaring obesity rates, traditional and farming communities experience much lower levels of obesity, a contrast often attributed to more physically demanding lifestyles.

This is where this recent study plays a big role. The study found that this assumption does not fully hold true. Even though physical activity across population, or the energy expenditure, that is the total calories burned daily is not significantly lower in industrialized population, their body size is larger. So, if not the energy output, then what is the reason? The answer lies in the diet.

How Was The Study Conducted?

The researchers analyzed data from 4,213 adults aged 18 to 60, representing 34 populations across six continents. Participants included hunter-gatherers, farmers, and urban dwellers. Using the DLW technique, the researchers measured total energy expenditure (TEE), basal energy expenditure (BEE), and active energy expenditure (AEE).

Although people in industrialized nations had higher total energy expenditures due to their larger body sizes, their activity levels, when adjusted for body size, were only slightly lower than those in traditional societies. This slight difference explained less than 10% of the overall increase in body mass index (BMI) and fat percentage. The main driver was higher calorie intake, often from ultra-processed, high-fat, and high-sugar foods.

Findings: Diet Matters More

“For public health professionals, these findings emphasize that improving diet quality, and reducing consumption of high-calorie, ultra-processed foods, may be far more effective than focusing solely on physical activity,” explained Cornelia Loechl, Head of Nutritional and Health-related Environmental Studies at the IAEA. “It underscores how impactful scientific data can guide better health policies.”

Thomas M. Holland, a physician-scientist at RUSH University in Chicago, who was not involved in the study, added: “This research reminds us that while exercise remains essential for overall health, obesity appears to be more closely tied to what and how much we eat. Economic development offers access to more food, but also increases exposure to obesogenic diets.”
