Why Do You Lose Weight? Learn More About the Real Reasons
Although weight loss sometimes seems natural, there can be many reasons behind it. It can also be a sign of health problems. Therefore, it is important to identify its causes.
If the food you eat does not provide adequate nutrients, your body weight will gradually decrease.
Severe anxiety and mental stress are more likely to cause weight loss due to loss of appetite.
Some types of treatments or medications, especially those for diseases such as thyroid and cancer, have the power to reduce weight.
Exercising without much effort or adequate food consumption can also reduce the body's energy and health.
Hormonal changes may be more noticeable in women than in men and often lead to unexpected weight loss
Why Do You Gain Weight? Is It Dangerous for You?
Unnecessary weight gain can be the first sign of health problems, not a hidden one. It depends on many factors that must be carefully addressed.
-
Eating high-calorie foods increases fat deposits in the body and leads to unwanted weight gain.
-
Lack of sleep and eating late at night negatively affect your metabolism and overall health.
-
Low physical activity, for example, sitting for a long time at work, significantly increases body weight.
-
Hormonal imbalances in the body, especially problems like PCOD and hypothyroidism, can cause weight gain.
-
A careless lifestyle and excessive consumption of junk food can have a serious impact on the body.

What Are the Natural Ways to Lose Weight?
To keep your body healthy, it is better to take the weight loss process naturally. There are some effective ways to do this.
-
Follow a daily diet plan and eat a low-calorie, high-fiber diet to promote healthy weight loss.
-
Exercising for at least 30 minutes every day is key to maintaining long-term weight control.
-
Reduce your intake of sweets and avoid high-fat foods like butter and oil.
-
Drinking enough water every day helps the body detoxify naturally and boosts metabolism.
-
Stress management techniques like meditation and pranayama can be very effective in supporting weight loss.
What Are the Natural Ways to Gain Weight?
Healthy weight gain is essential for those who are extremely weak. This also requires special care and attention to nutrition.
-
It is better to eat nutritious food that provides more calories in a short period of time.
-
Make sure that proteins, fats, and carbohydrates are balanced in each meal you consume.
-
Proper rest, sleep, and mental health are essential to gain weight without excessive exertion.
-
Eating more than 3 small meals a day provides the body with consistent energy and nutrition.
-
It is necessary to accustom the body to increase mass through exercise, especially resistance training.
Difference Between Weight Gain and Weight Loss
| Aspect | Weight Loss | Weight Gain |
|---|---|---|
| Cause | Lack of nutrients, stress, illness, or over-exercising. | High-calorie diet, inactivity, hormonal imbalance, and poor sleep. |
| Effect | Fatigue, weakness, loss, and muscle reduction. | Obesity, diabetes, high BP, and heart strain. |
| Diet Tips | Low-calorie, high-fiber food with portion control. | Nutritious, energy-dense meals rich in protein and fat. |
| Exercise | Regular cardio and strength training to burn fat. | Muscle-building workouts to increase healthy mass. |
| Mental Health | Stress and anxiety may suppress appetite and energy. | Emotional eating due to stress or low self-esteem. |
| Health Risks | Malnutrition, anemia, weak bones, and hormonal issues. | Chronic diseases like PCOS, diabetes, and liver problems. |
| Solutions | Balanced meals, hydration, rest, and therapy if needed. | Healthy eating, planned exercise, and avoiding processed food. |
What Are the Health Problems Associated with Weight?
Both weight loss and weight gain can lead to several health problems. If ignored, these issues can become long-term risks.
Those who lose weight often face problems like sickness, dizziness, and chronic fatigue.
Those who gain weight are more prone to diseases like high blood pressure, diabetes, and heart-related issues.
People who are under stress tend to either lose their appetite or overeat, which severely affects body weight.
Weight changes are often caused by PCOS in women and low testosterone levels in men.
If old habits are not changed, the body’s health will continue to decline over time
Top 25 MCQs on Weight Management for UPSC Exams
Test your understanding of weight management through 25 carefully designed UPSC-level MCQs covering nutrition, metabolism, physical activity, obesity risks, and sustainable strategies for healthy body weight.
1. The fundamental principle of weight loss is creating a "Caloric Deficit." What does this mean?
a) Eating only fat
b) Consuming fewer calories than your body burns
c) Exercising 5 hours a day
d) Drinking only water
Expand Text
Answer: b) Consuming fewer calories than your body burns
When energy expenditure exceeds energy intake, the body metabolizes stored fat for fuel, resulting in weight loss.
2. What does "BMI" stand for?
a) Body Mass Index
b) Basal Metabolic Indicator
c) Body Muscle Indicator
d) Basic Mass Index
Expand Text
Answer: a) Body Mass Index
It is a screening tool calculated from a person's height and weight to estimate body fat and health risk categories (underweight, normal, overweight, obese).
3. Which component of metabolism burns the most calories daily (60-75%)?
a) Exercise
b) Digestion (TEF)
c) Basal Metabolic Rate (BMR)
d) Walking
Expand Text
Answer: c) Basal Metabolic Rate (BMR)
This is the energy your body needs just to keep you alive at rest—breathing, circulating blood, and cell production.
4. Which hormone is known as the "Hunger Hormone" because it signals the brain to eat?
a) Leptin
b) Ghrelin
c) Insulin
d) Cortisol
Expand Text
Answer: b) Ghrelin
Produced in the stomach, ghrelin levels rise before meals and fall after eating. Lack of sleep can abnormally increase ghrelin.
5. Conversely, which hormone is the "Satiety Hormone" that tells the brain you are full?
a) Ghrelin
b) Leptin
c) Adrenaline
d) Estrogen
Expand Text
Answer: b) Leptin
Produced by fat cells, it signals the brain that there is enough energy stored. In obesity, people often become "Leptin Resistant."
6. Why is "Protein" considered the most friendly macronutrient for weight loss?
a) It has zero calories
b) It increases satiety and has a high Thermic Effect (burns more calories to digest)
c) It tastes sweet
d) It removes water weight
Expand Text
Answer: b) It increases satiety and has a high Thermic Effect
The body uses about 20-30% of the calories in protein just to digest it, compared to only 5-10% for carbs.
7. "Visceral Fat" is dangerous because it is stored:
a) Under the skin of the arms
b) Around the internal organs (liver, pancreas)
c) In the feet
d) In the kneecaps
Expand Text
Answer: b) Around the internal organs (liver, pancreas)

This "active fat" releases inflammatory markers and is strongly linked to Type 2 diabetes and heart disease.
8. Strength Training (lifting weights) aids weight management by:
a) Burning fat only during the workout
b) Building muscle, which increases Resting Metabolic Rate (burns more calories at rest)
c) Making you heavier
d) Reducing appetite permanently
Expand Text
Answer: b) Building muscle, which increases Resting Metabolic Rate
Muscle tissue is metabolically expensive; having more muscle means your body burns more calories even while you sleep.
9. What is "NEAT"?
a) Non-Exercise Activity Thermogenesis
b) New Eating Activity Time
c) Never Eat At Table
d) Nutritional Energy And Time
Expand Text
Answer: a) Non-Exercise Activity Thermogenesis
It refers to calories burned by daily movements like fidgeting, walking to work, cleaning, or standing, which can be significant.
10. "Empty Calories" usually refers to food containing:
a) High protein and water
b) High sugar/fats but low nutritional value (vitamins/minerals)
c) No calories at all
d) Fiber only
Expand Text
Answer: b) High sugar/fats but low nutritional value (vitamins/minerals)
Examples include soda, candy, and alcohol. They provide energy but do not satiate hunger or nourish the body.
11. Why is "Fiber" important for weight control?
a) It speeds up heart rate
b) It adds bulk to food, slows digestion, and keeps you full longer
c) It turns into muscle
d) It tastes salty
Expand Text
Answer: b) It adds bulk to food, slows digestion, and keeps you full longer
Soluble fiber also feeds gut bacteria. High-fiber foods usually require more chewing, giving the brain time to register fullness.
12. "Intermittent Fasting" (e.g., 16:8) is a strategy that focuses on:
a) Eliminating carbs
b) When you eat (eating windows) rather than just what you eat
c) Eating only liquids
d) Excessive exercise
Expand Text
Answer: b) When you eat (eating windows) rather than just what you eat
It helps lower insulin levels and naturally restricts caloric intake by removing a meal (usually breakfast or late-night snacks).
13. How long does it typically take for the brain to register that the stomach is full?
a) Instantly
b) 5 minutes
c) 20 minutes
d) 1 hour
Expand Text
Answer: c) 20 minutes
Eating slowly gives the satiety signals time to reach the brain, preventing overeating.
14. The "Ketogenic Diet" (Keto) forces the body to burn what for fuel instead of glucose?
a) Muscle
b) Fat (Ketones)
c) Water
d) Fiber
Expand Text
Answer: b) Fat (Ketones)
By drastically cutting carbohydrates, the body enters a metabolic state called "Ketosis," burning stored fat for energy.
15. Why should you be careful with "Liquid Calories" (juices, sodas)?
a) They evaporate
b) They don't trigger fullness signals like solid food, leading to calorie surplus
c) They are too cold
d) They have no taste
Expand Text
Answer: b) They don't trigger fullness signals like solid food, leading to calorie surplus
It is very easy to drink 500 calories in a few minutes without feeling satisfied.
16. "Mindful Eating" involves:
a) Eating while watching TV
b) Eating without distraction and paying attention to hunger cues
c) Counting every calorie
d) Eating as fast as possible
Expand Text
Answer: b) Eating without distraction and paying attention to hunger cues
This psychological approach reduces binge eating and promotes a healthier relationship with food.
17. Chronic Sleep Deprivation (less than 6 hours) is linked to obesity because it:
a) Burns too many calories
b) Increases Ghrelin (hunger) and decreases Leptin (fullness)
c) Makes you run faster
d) Decreases appetite
Expand Text
Answer: b) Increases Ghrelin (hunger) and decreases Leptin (fullness)
Tired brains also crave high-sugar, high-carb foods for a quick energy fix.
18. What is a "Weight Loss Plateau"?
a) When weight loss stops despite continuing diet/exercise
b) Losing weight too fast
c) Gaining muscle
d) A flat stomach
Expand Text
Answer: a) When weight loss stops despite continuing diet/exercise
As you lose weight, your body requires fewer calories to function (metabolic adaptation), so you must adjust intake or activity to continue losing.
19. "Portion Distortion" refers to:
a) Blurred vision
b) The trend of serving sizes becoming much larger over time
c) Broken plates
d) Eating tiny meals
Expand Text
Answer: b) The trend of serving sizes becoming much larger over time
Modern restaurant portions are often 2-3 times larger than the standard recommended serving size.
20. Drinking a glass of water before a meal can help weight loss by:
a) Burning fat directly
b) Increasing temporary fullness, leading to eating less
c) Removing vitamins
d) Freezing the stomach
Expand Text
Answer: b) Increasing temporary fullness, leading to eating less
Often, the body confuses thirst signals with hunger signals. Staying hydrated prevents false hunger.
21. "Cortisol" (Stress Hormone) promotes fat storage primarily in which area?
a) Hips
b) Abdomen (Belly)
c) Arms
d) Feet
Expand Text
Answer: b) Abdomen (Belly)
Chronic stress leads to elevated cortisol, which encourages the accumulation of visceral fat.
22. What is the "Yo-Yo Effect" (Weight Cycling)?
a) Playing with toys
b) Losing weight and regaining it repeatedly
c) Steady weight loss
d) Gaining muscle fast
Expand Text
Answer: b) Losing weight and regaining it repeatedly
This often happens with restrictive fad diets. It can slow metabolism and make future weight loss harder.
23. "Processed Foods" are designed to be "Hyper-palatable," meaning:
a) They taste bad
b) They are chemically engineered to be extremely tasty and addictive
c) They are very healthy
d) They are tasteless
Expand Text
Answer: b) They are chemically engineered to be extremely tasty and addictive
The specific combination of sugar, salt, and fat overrides the brain's "stop eating" signals.
24. Which cooking method adds the most unnecessary calories to food?
a) Steaming
b) Deep Frying
c) Baking
d) Grilling
Expand Text
Answer: b) Deep Frying
Food acts like a sponge, absorbing the cooking oil. Oils are calorie-dense (approx 120 calories per tablespoon).
25. A sustainable rate of weight loss is generally considered to be:
a) 5-10 lbs per week
b) 1-2 lbs per week
c) 1 lb per month
d) 20 lbs per month
Expand Text
Answer: b) 1-2 lbs per week
Losing weight faster often means losing muscle and water, not fat, and increases the likelihood of regaining it.
