Most girls are afraid of carbohydrates and strive to completely eliminate them from the diet. But is it justified? How carbohydrates affect our weight, and how much of them is safe for the figure. Today we will analyze the topic of carbohydrates for women: the daily intake, the intake for weight loss, what their excess and deficiency lead to, and which carbohydrates should be chosen.
Carbohydrates are not only very tasty, they are also useful if you do not go overboard with their quantity and choose quality sources. All carbohydrates contained in food are different and affect the body in different ways.
Carbohydrates act as a source of energy for cells. When you eat carbohydrate foods, carbohydrates are broken down into smaller compounds, such as glucose, and provide fuel for your body's cells. Excess carbohydrates are stored as glycogen in the liver and muscles. When the body does not get enough carbohydrates from food, it turns to these glycogen stores.
Certain types of carbohydrates also play a key role in digestion, heart health, and brain function. In some cases, the body is able to convert other nutrients, such as proteins or fats, into glucose to perform certain functions. In other cases, a lack of certain types, such as fiber, can affect everything from cholesterol levels to bowel function. In addition, carbohydrates are needed for metabolism, muscle function and the nervous system. Therefore, you cannot independently exclude carbohydrates from the diet - you need to do this only according to indications and under the supervision of a specialist.
Excessive consumption of carbohydrates paired with low energy consumption leads to weight gain. Therefore, it is believed that an excess of carbohydrates in the diet leads to obesity, metabolic disorders, high cholesterol and the development of diabetes.
The required daily intake of carbohydrates for a woman depends on many factors:
age;
health status;
goals;
level of physical activity;
individual preferences.
Therefore, it will not be correct to display one general figure for all women. For example, Masha, who works in an office and has insulin resistance, and Marina, a fitness trainer with workouts every day, will have completely different carbohydrate needs. One leads a sedentary lifestyle and already has health problems, while the other moves a lot and needs a lot of energy. Even if they are the same age and pursue the same goals, their daily carbohydrate intake will be radically different.
To sum it up: the amount of carbohydrates depends on the level of physical activity, lifestyle and health in general. And, of course, the daily intake of carbohydrates depends primarily on the goal of a woman: maintenance, weight gain or weight loss. Depending on the initial state of the woman and her goals for health and figure, a decision is made about how many carbohydrates she needs.
There are some general numbers that you can focus on, but you should not take them as the only true ones. According to the American Dietary Guidelines, carbohydrates should make up 45 to 65 percent of your daily calorie intake. We remind you that this is only a general figure for a conditionally healthy person without taking into account his goals and characteristics.
It is believed that to maintain body weight, it is enough to consume 2-5 g of carbohydrates per day per 1 kg of body weight. When gaining muscle mass, this number is increased, and when losing weight, it is reduced.
For weight loss, women often use low-carb diets, which, according to research, do work. Reducing carbs can often help you lose weight without counting calories by simply limiting your carb sources.
In order to lose weight, the amount of carbohydrates is reduced to 50-150 grams per day. This can have both its advantages and disadvantages.
Research shows that low-carbohydrate diets can be part of an effective weight loss strategy. They limit carbohydrate intake while replacing them with proteins, healthy fats, and vegetables. They are believed to help reduce a person's appetite (through quality sources of fat in the diet) and cause them to eat fewer calories than other diets.
Study: The Effects of a Low-Carbohydrate Diet on Appetite: A Randomized Controlled Trial
It is worth noting that in addition to weight loss, low-carbohydrate diets have other benefits. They can help lower blood sugar, blood pressure, and triglycerides, as well as raise HDL (good) cholesterol and improve the structure of LDL (bad) cholesterol.
Study: Health Effects of Low-Carbohydrate Diets: Where Should New Research Go, Effects of Low-Carbohydrate Diets Versus Low-Fat Diets on Metabolic Risk Factors: A Meta-Analysis of Randomized Controlled Clinical Trials
As we said, the optimal amount of dietary carbohydrates varies for each person. Many experts recommend consuming 15-30% of total calories as carbohydrates. For most women, this is usually 75-150 grams per day, although increases or decreases may be recommended on a case-by-case basis.
For some women, it is better not to resort to extremely low carbohydrate values, but to consume a moderate amount of carbohydrates, about 100-150 grams. in a day.
This applies to women who:
lead an active lifestyle and need to recover after training;
have thyroid problems
have amenorrhea or irregular cycles;
have been on a highly low-carbohydrate diet for an extended period of time;
are pregnant or breastfeeding.

weight loss;
improved mood and energy levels;
normal menstrual function;
sleep improvement.
For some women, such as athletes or those who wish to gain muscle mass, a carbohydrate intake of more than 150 grams will be more appropriate.
For some women, a lower carbohydrate intake is recommended, but under the supervision of a specialist.
This applies to women who:
Are overweight or obese.
They lead a sedentary lifestyle.
Have polycystic ovary syndrome (PCOS), fibroids, or endometriosis. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC1334192/

Female hormones are sensitive to energy availability, meaning that too few calories or carbohydrates can cause an imbalance. This imbalance can have very serious consequences, including impaired fertility, bad mood, and even weight gain.
However, most evidence suggests that these effects tend to occur only in women on a long-term, very low-carbohydrate diet (less than 50 grams per day).
Each person is different, and optimal carbohydrate intake varies greatly between individuals. There is no one solution that fits all. Some people do best on a very low carb diet, while others function best on a moderate to high carb diet.
To find out what amount of carbs works best for you, try experimenting and adjust your carb intake based on how you feel, how much energy you have, and how you look.
But, despite the fact that low-carb diets have their advantages, it is necessary to consider the impact of reducing carbohydrates on the female body.
Low carb diets can be good for some people and cause problems for others. For example, long-term adherence to a low-carbohydrate diet can lead to hormonal imbalance in some women.
The dangers of low-carb diets for women.
carbohydrates and hormones.
Hormones are regulated by three main glands:
Hypothalamus: Located in the brain.
Pituitary gland: located in the brain.
Adrenal glands: located at the top of the kidneys.
All three glands interact in complex ways to keep hormones in balance. This is the so-called hypothalamic-pituitary-adrenal (HPA) axis.
It is responsible for regulating stress levels, mood, emotions, digestion, immune system, sex drive, metabolism, energy levels. The glands are sensitive to things like calorie intake, stress, and exercise levels.
Prolonged stress can lead to an overproduction of the hormones cortisol and norepinephrine, creating an imbalance that increases pressure on the hypothalamus, pituitary, and adrenal glands. This continued pressure can eventually lead to axis dysfunction.
Study: The role of stress and the hypothalamic-pituitary-adrenal axis in the pathogenesis of the metabolic syndrome: neuro-endocrine and target tissue-related causes, Diurnal variation of adrenocortical activity in chronic fatigue syndrome
Symptoms:
fatigue;
weakened immune system;
increased risk of long-term health problems: hypothyroidism, inflammation, diabetes, etc.
Many sources suggest that a diet too low in calories or carbohydrates can also act as a stressor, causing HPA axis dysfunction. In addition, some evidence suggests that low-carbohydrate diets can cause increased production of cortisol (“stress hormone”), exacerbating the problem. https://pubmed.ncbi.nlm.nih.gov/22735432/
For example, one study found that, regardless of weight loss, a low-carb diet increased cortisol levels compared to a moderate-fat, low-carb diet. https://pubmed.ncbi.nlm.nih.gov/17785367/
To recap: Eating too few carbohydrates or calories in general, coupled with chronic stress, can disrupt the HPA axis, causing hormonal problems.
Carbohydrates and cycle.
With prolonged thoughtless exclusion of carbohydrates, problems with the cycle or amenorrhea may occur.
Amenorrhea is defined as the absence of a menstrual cycle in a woman for 3 months or more. The most common cause of amenorrhea is hypothalamic amenorrhea.
The reasons:
too few calories
too few carbohydrates;
sudden weight loss;
stress;
too much physical activity.
Amenorrhea occurs due to a drop in the level of hormones that trigger the menstrual cycle. This leads to a domino effect causing other hormones such as luteinizing hormone (LH), follicle stimulating hormone (FSH), estrogen, progesterone and testosterone to drop. https://pubmed.ncbi.nlm.nih.gov/12519869/
Low levels of leptin, a hormone produced by fat cells, is another potential cause of amenorrhea and irregular periods. Evidence suggests that women need certain levels of leptin to maintain normal menstrual function. https://pubmed.ncbi.nlm.nih.gov/17851226/
Too few carbohydrates or calories in the diet can lead to suppression of leptin levels and impair leptin's ability to regulate reproductive hormones. This is especially critical for underweight or lean women on a low-carbohydrate diet.
However, it should be noted that data on amenorrhea on low carbohydrate diets is not yet sufficient. Studies that have reported amenorrhea as a side effect have usually been done on women following a predominantly low-carbohydrate diet for an extended period of time. https://pubmed.ncbi.nlm.nih.gov/22004525/
A study of 20 teenage girls following a ketogenic diet for 6 months found that 45% experienced menstrual problems and 6 experienced amenorrhea. https://pubmed.ncbi.nlm.nih.gov/12790900/
Conclusion: Using a highly low-carbohydrate (ketogenic) diet for an extended period of time may cause irregular menstrual cycles or amenorrhea.
Carbohydrates and the thyroid gland.
The thyroid gland produces two hormones: thyroxine (T4) and triiodothyronine (T3).
These two hormones are essential for a wide range of bodily functions:
breath;
heart rate;
nervous system;
body mass;
temperature control;
cholesterol level;
menstrual cycle.
T3, the active thyroid hormone, is highly sensitive to calorie and carbohydrate intake. If caloric or carbohydrate intake is too low, T3 levels fall and reverse T3 (rT3) levels rise.
Study: Diurnal variation of adrenocortical activity in chronic fatigue syndrome
Reverse (reverse) T3 is a hormone that blocks the action of T3. Some studies have shown that ketogenic diets lower T3 levels. For example, one study showed that T3 levels decreased by 47% within 2 weeks in people consuming a carbohydrate-free diet. In contrast, people consuming the same calories but at least 50 grams of carbs daily experienced no change in T3 levels.
Study: Effect of caloric restriction and dietary composition of serum T3 and reverse T3 in man
Low T3 and high reverse T3 can slow down metabolism, leading to weight gain, fatigue, lack of concentration, and a bad mood.
One study found that 1 year of a moderate carbohydrate diet (46% of total energy intake) had a more positive effect on mood than a long-term very low carbohydrate diet (4% of total energy intake) in overweight adults and obesity.
Study: Long-term effects of a very low-carbohydrate diet and a low-fat diet on mood and cognitive function
Conclusion: Reducing carbs too much can lead to decreased thyroid function in some people. This can manifest itself as fatigue, weight gain and a bad mood.
Tables or various calorie counters will help determine the amount of carbohydrates in foods. But, it is very important to focus not only on the numbers, but also on the quality of these carbohydrates. So, calories from a cake and calories from chickpeas are completely different calories that will affect the body in different ways. Therefore, it is always better to direct your attention to the products themselves, and not to dry numbers. Tables with the content of carbohydrates can serve as a guide and help you make the right choice when planning your diet.

Not all carbohydrates are created equal. There are many different types of carbohydrate-containing foods, and they can vary in their health effects. Carbohydrates are usually divided into “simple” and “complex” or “whole” and “refined”. Let's figure out which of them are more correct.
Whole carbs are unprocessed and contain fiber, while refined carbs go through processing and natural fiber removal.
Examples of Whole Good Carbohydrates:
vegetables;
quinoa;
barley;
legumes;
potato;
whole grains.

"Proteins in products for weight loss: features of protein diets and a sample menu" MoreRefined carbohydrates:
sugar-sweetened drinks;
White bread;
bakery products;
other products made from white flour.
Numerous studies show that consumption of refined carbohydrates is associated with obesity and type 2 diabetes.
Study: Glycemic Index, Glycemic Load, Carbohydrates, and Type 2 Diabetes, Dietary carbohydrates, refined grains, glycemic load, and risk of coronary heart disease in Chinese adults
Refined carbohydrates tend to cause increased hunger and unhealthy food cravings. In addition, they are poor in nutrients - these are "empty" calories.
However, do not demonize all carbohydrate-containing foods. Whole carb sources are loaded with nutrients and fiber and don't cause spikes or dips in sugar levels. Numerous studies on high-fiber carbohydrates, including vegetables, fruits, legumes, and whole grains, show that eating them is associated with improved metabolic health and a reduced risk of disease.

Instead of thinking of carbohydrates as "good" or "bad", focus on increasing your whole and complex sources of carbohydrates.
List of correct carbohydrates:
Vegetables. Try to add a variety of carbohydrate sources from vegetables to your diet every day.
Whole fruits: apples, bananas, kiwis, oranges, grapefruits.
Berries: blueberries, raspberries, strawberries, blueberries, currants.
Legumes: lentils, beans, peas.
Nuts: almonds, walnuts, hazelnuts, macadamia.
Seeds: Chia seeds, pumpkin and hemp seeds.
Whole grains: quinoa, brown rice, buckwheat.
Sources of carbohydrates that should be limited or eliminated whenever possible:
Sugary drinks: carbonated drinks, fruit juices with added sugar, and all drinks sweetened with high fructose syrups.
White bread. These are refined carbohydrates that are low in essential nutrients and negatively affect metabolism.
Baking, cookies and cakes.
Ice cream.
Sweets and chocolates. If you still choose chocolate, let it be quality dark chocolate.
French fries and potato chips.
