Verywell Fit uses only high-quality sources, including peer-reviewed studies, to support the facts within our articles. Whether you're trying to lose weight , maintain your current weight, or gain more, calories matter. Yes, partially because they can affect your weight and fitness , but also because they have the very basic yet hugely important job of helping you stay alive. Consuming just enough won't cut it, as your body and mind can suffer in plenty of ways without the proper nourishment.
Experts advise not dipping below 1, calories a day for women. Even then, that's the bare minimum that may not get you all the nutrients you need. There aren't many upsides to eating too few calories, not even long-lasting weight loss. Here, Pojednic and Zeitlin share seven ways your body might be telling you it needs more food. When your calories are too low, your energy is too low," says Zeitlin. That lack of spirit can show everywhere from the weight room to your morning meeting. That's because your body is allocating the calories you take in to its most important task: supporting parts of your body like your brain and heart.
If you don't have much leftover, doing things that require tons of energy will seem harder and way less appealing. If you're aiming for long-lasting weight loss, drastically slashing your calories may not be the best way to go. If you want to know more about intermittent fasting you can read about that here.
As noted, muscle tissue uses more calories than fat at rest and during exercise. If you lose muscle mass, you slow your metabolism further, making weight loss that much harder. Eating too few calories can also cause your body to pump out fewer of the hormones that make you feel full and more of those that make you feel hungry. The hormone leptin decreases hunger and the hormone ghrelin increases it.
Because of uncontrollable hunger, it can be hard to stick to a restrictive diet, so you may cheat, binge and undermine your intentions. You crave high-calorie foods and can't stick to your low-calorie plan to lose weight.
This isn't a lack of willpower, it's your attempts to eat too few calories that are undoing your valiant efforts to drop pounds. Healthline points out that you may become deficient in protein, calcium, biotin, thiamine, vitamin A and magnesium. Nutrient imbalances cause fatigue and low energy, negatively affect bone and muscle development, and compromise the health of your skin, hair and nails.
You may find your physical performance suffers, too — especially relevant if you're an athlete. Infertility can also occur as a result of too few calories. Your body's production of sex hormones may reduce because of a too low-calorie intake. The American Journal of Endocrinology, Physiology and Metabolism published a study in showing that, in women, reductions in calories of 22 to 42 percent below what's needed to maintain their weight can lead to menstrual irregularities indicating problems with ovulation.
Mood disorders and depression can occur. Harvard Health Publishing explains that this can cause nutritional deficiencies and may trigger a lowered metabolism and hormone imbalances.
You may wonder exactly how many calories you should aim to eat then. Everyone is different, which is why using a weight-loss calculator makes sense. Unhealthy distractions include watching TV, reading a book, using your mobile phone, or sitting at your computer while eating. Instead, try eating mindfully. Many popular brands of ice cream and chocolate come in small- as well as full-size versions.
If you want a sweet treat, choosing a smaller version of your favorite dessert can give you the fix you want and save you a lot of calories. Restaurants often serve huge portions that contain far more calories than you need in one sitting. To avoid eating too much, ask your server to wrap up half of your meal before they serve it so you can take it home. One study found that people who successfully maintained weight loss often shared food or ordered half portions when they ate out Eating more protein is considered a useful tool for weight loss and maintenance.
One reason for this is that protein can fill you up more than other nutrients, and feeling full can stop you from overeating. To get these benefits, try including a high-protein food with most of your meals Overly large portions are a primary reason for people overeating 14 , Choose clear alcohol with a low-calorie mixer over beer, wine, or a cocktail.
This will help you avoid excessive calories from the drinks. Sometimes, getting a larger drink or side for only a small increase in price may sound like a better deal. However, most restaurants already serve oversized food and drink portions, so stick to the regular size. Extra cheese is often an option in restaurants. Still, even a single slice of cheese can add around calories to your meal Cooking your own meals is a great way to keep your meals healthy and your calorie intake under control.
Grilling, air-frying, steaming, stewing, boiling or poaching are healthier options than frying in oil. If you have a choice, select a tomato-based sauce over a creamy one to get the double benefit of fewer calories and more healthy vegetables. Whole fruits pack fiber , vitamins, minerals, and antioxidants, making them an excellent addition to your diet. Additionally, compared to fruit juice, fruits are difficult to overeat, as they fill you up 42 , Whenever possible, choose whole fruits over fruit juice.
If you like eating snacks, such as chips and dips, while watching TV but want to cut back on calories, simply opt for healthy vegetables instead. For example, a skinless roasted chicken breast is around calories.
The same breast with skin contains calories 44 , If you want to enjoy some pizza , keep the calories to a minimum by choosing a thinner crust and lower-calorie toppings, such as vegetables. Intermittent fasting is a popular weight loss method that can help you cut calories. This approach to dieting works by cycling your eating patterns between periods of fasting and eating.
