What Will Happen if I Eat 100-200 Calories a Day, for 1 Month?

What will happen if I eat 100-200 Calories a Day, for 1 month?

Eating only 100-200 calories a day for a month can lead to severe malnutrition, extreme weight loss, muscle wasting, nutrient deficiencies, weakened immune system, organ damage, and increased risk of eating disorders. It is highly recommended to consult with a healthcare professional before making any significant changes to your diet.

Eating only 100-200 calories a day for an extended period, such as one month, can have severe implications for your health. It’s important to note that this answer is for informational purposes only, and it’s crucial to consult with a healthcare professional or a registered dietitian before making any drastic changes to your diet.

  1. Rapid Weight Loss: Consuming such a low number of calories would likely result in significant weight loss. This is because your body would not be receiving enough energy to sustain its daily functions and would start utilizing stored fat for fuel.
  2. Muscle Loss: While your body may initially use stored fat for energy, it would eventually turn to breaking down muscle tissue as well. This can lead to muscle wasting, weakness, and a slower metabolism in the long term.
  3. Nutritional Deficiencies: Restricting calories to such an extreme extent would severely limit your intake of essential nutrients, including proteins, carbohydrates, fats, vitamins, and minerals. This can result in various deficiencies, causing fatigue, dizziness, weakened immune function, hair loss, hormonal imbalances, and impaired cognitive function.
  4. Metabolic Adaptation: Prolonged caloric restriction can cause your metabolism to slow down as your body tries to conserve energy. This can make it more challenging to lose weight in the future and may lead to weight gain once you return to a regular diet.
  5. Organ Damage: Insufficient calorie intake can put a strain on your organs, particularly your heart, liver, and kidneys. This can increase the risk of cardiovascular problems, liver dysfunction, and kidney damage.
  6. Nutritional and Psychological Disorders: Severe caloric restriction can trigger disordered eating patterns and may lead to the development of eating disorders such as anorexia nervosa or orthorexia. These conditions can have long-lasting physical and psychological consequences.
  7. Overall Health Complications: In addition to the specific issues mentioned above, consuming too few calories can weaken your immune system, increase your susceptibility to infections, impair wound healing, disrupt hormonal balance, and lead to electrolyte imbalances.

It’s essential to maintain a balanced and varied diet that provides adequate calories and nutrients for your body’s needs. If you’re looking to lose weight or make dietary changes, it’s best to consult a healthcare professional or a registered dietitian who can guide you in a safe and sustainable manner.

What if I eat 200 calories for a month?

Eating only 200 calories a day for a month would still be considered an extreme and highly restrictive form of caloric intake. Similar to the scenario of consuming 100-200 calories per day, the consequences would likely include severe weight loss, muscle wasting, nutrient deficiencies, weakened immune system, organ damage, and an increased risk of developing eating disorders. It is crucial to prioritize your health and consult with a healthcare professional before embarking on any such restrictive eating plan.

How much weight would I lose if I ate 100 calories a day?


If you were to eat only 100 calories a day, your weight loss would largely depend on various factors such as your current weight, age, height, metabolism, and activity level. However, consuming only 100 calories a day is an extremely low intake that is not sustainable or healthy in the long term.

Generally, a pound of body weight is estimated to be equivalent to approximately 3,500 calories. Therefore, if you were to create a calorie deficit of 3,500 calories, you might expect to lose around 1 pound (0.45 kg). However, it’s important to note that this estimation can vary significantly from person to person.

How much weight will I lose if I cut 200 calories per day?


Cutting 200 calories per day from your diet can lead to gradual and sustainable weight loss over time. The amount of weight you would lose depends on various factors, including your current weight, age, height, metabolism, and activity level.

To estimate the weight loss, you can use the general guideline that a pound of body weight is approximately equivalent to 3,500 calories. By reducing your daily intake by 200 calories, you would create a calorie deficit of 200 calories per day or 1,400 calories per week.

If we assume that a pound of weight loss is equivalent to a calorie deficit of 3,500 calories, cutting 200 calories per day would result in a weekly deficit of 1,400 calories. Over time, this could lead to a weight loss of approximately 0.4 pounds (0.18 kg) per week.

It’s important to note that weight loss is not always linear, and individual results may vary. Factors such as individual metabolism, body composition, and overall lifestyle play a role in weight changes. It’s recommended to focus on sustainable, long-term habits like a balanced diet and regular physical activity rather than solely relying on calorie reduction for weight loss.

Can I survive on 200 calories per day?

Surviving on only 200 calories per day is not sustainable or healthy for the majority of individuals. The human body requires a sufficient amount of calories to perform basic bodily functions, such as maintaining organ function, supporting brain activity, and carrying out daily activities.

The average adult requires significantly more than 200 calories per day to meet their energy needs. Severely restricting calorie intake to such an extent can have serious health consequences, including:

  1. Malnutrition: Consuming only 200 calories per day would likely result in severe nutrient deficiencies, as it would be challenging to obtain all the necessary macronutrients (carbohydrates, proteins, and fats) and micronutrients (vitamins and minerals) required for optimal health.
  2. Muscle wasting: Inadequate calorie intake can lead to muscle breakdown as the body seeks alternative sources of energy. This can result in muscle weakness, decreased physical performance, and a slower metabolism.
  3. Fatigue and weakness: Insufficient energy intake can lead to feelings of fatigue, weakness, and low energy levels. It can impact daily activities, cognitive function, and overall quality of life.
  4. Weakened immune system: Proper nutrition is vital for maintaining a robust immune system. Severely restricting calories can compromise the immune response, making individuals more susceptible to infections and illnesses.
  5. Organ damage: The organs, such as the heart, liver, and kidneys, require energy to function optimally. Inadequate calorie intake can put strain on these organs, leading to potential damage and long-term health issues.
