Underweight: The Causes and Natural Treatments.
Maintaining a healthy weight is essential for overall well-being. While much attention is often given to weight loss, being underweight can be equally concerning. Underweight individuals may suffer from fatigue, a weakened immune system, nutritional deficiencies, fertility issues, and in severe cases, organ failure. Fortunately, with the right knowledge and care, it is entirely possible to treat and overcome underweight conditions naturally and effectively.
🔬 What is Underweight?
A person is considered underweight if their Body Mass Index (BMI) is below 18.5. However, BMI alone is not always a reliable measure of health. Some people may have low body weight but still be healthy and strong. The real concern arises when the low weight is caused by poor nutrition, chronic illness, or mental health conditions.
🚨 Major Causes of Underweight
1. Fast Metabolism
People with a high metabolic rate burn calories quickly, often before the body has a chance to store them. These individuals may find it difficult to gain weight even when consuming large meals.
2. Poor Diet and Eating Habits
Skipping meals, eating low-calorie foods, or following restrictive diets can lead to chronic undernourishment. Even people who eat frequently may still be underweight if their diet lacks essential nutrients, fats, and proteins.
3. Chronic Illnesses
Several diseases can lead to weight loss, including:
- Diabetes – causes excessive urination and weight loss due to poor glucose absorption.
- Cancer – many cancers increase metabolism and reduce appetite.
- Hyperthyroidism – the thyroid gland produces excessive hormones, causing rapid calorie burning.
- Digestive disorders – such as Crohn’s disease, celiac disease, or ulcerative colitis, interfere with nutrient absorption.
- Tuberculosis or parasitic infections – cause ongoing weight loss.
4. Mental Health Conditions
- Depression and anxiety often suppress appetite and reduce interest in food.
- Eating disorders, such as anorexia nervosa or bulimia, are serious psychological conditions that require professional intervention.
5. Medications
Certain drugs (e.g., chemotherapy, antidepressants, thyroid medications) can cause appetite suppression, nausea, or poor digestion leading to unintentional weight loss.
6. Genetic Factors
Some individuals are naturally slim due to inherited body types or metabolic traits. While they may appear underweight, they might be perfectly healthy if other parameters are normal.
🌿 Natural Treatments for Underweight – A Holistic Approach
✅ 1. High-Calorie Nutrient-Dense Diet
To gain healthy weight, it’s not about eating junk food—it’s about quality and quantity. Choose calorie-rich foods that also provide essential vitamins and minerals:
- Nuts and nut butters: almonds, walnuts, peanut butter
- Healthy oils: olive oil, flaxseed oil, avocado oil
- Dairy products: full-fat milk, cheese, yogurt
- Whole grains: oats, brown rice, whole-wheat pasta
- Legumes: lentils, chickpeas, black beans
- Fruits and vegetables: bananas, mangoes, avocados, sweet potatoes
✅ 2. Frequent Meals and Snacking
- Eat five to six small meals a day instead of three large ones.
- Include snacks like granola bars, smoothies, trail mix, or boiled eggs between meals.
✅ 3. Increase Protein Intake
Protein supports muscle growth and repair:
- Include eggs, chicken, fish, lentils, tofu, Greek yogurt, quinoa, and whey protein in your meals.
- Protein shakes after workouts can help build lean mass.
✅ 4. Strength and Resistance Training
- Combine diet with strength training (weight lifting, resistance bands, bodyweight exercises) to ensure that the weight gained is muscle, not fat.
- Exercise increases appetite and promotes the release of hormones that regulate body composition.
✅ 5. Healthy Smoothies and Shakes
- Use ingredients like milk, bananas, oats, peanut butter, cocoa powder, dates, and honey to make high-calorie shakes.
- Add chia seeds or flax seeds for omega-3 fats and fiber.
✅ 6. Rest and Recovery
- Sleep is essential for muscle recovery and hormonal balance.
- Aim for 7–9 hours of quality sleep each night.
🧘♀️ Stress, Hormones, and Mental Wellness
Stress can significantly affect your metabolism and appetite. Try:
- Yoga and meditation to reduce anxiety.
- Adaptogens like ashwagandha or holy basil (under medical guidance) to support stress management.
- Counseling or therapy if you suspect emotional or psychological causes.
🌱 Herbal Remedies and Natural Supplements (Use With Care)
- Ashwagandha: Improves appetite and reduces stress.
- Fenugreek: Stimulates appetite and improves digestion.
- Ginger and fennel seeds: Relieve bloating and enhance nutrient absorption.
- Alfalfa and spirulina: Nutrient-dense plant supplements to support weight gain.
⚠️ Always consult a healthcare provider before using herbs, especially if you are taking medications or have chronic conditions.
👨⚕️ When to See a Doctor
Seek professional help if:
- You are losing weight without trying.
- You have digestive issues, constant fatigue, or loss of appetite.
- You are unable to gain weight despite eating well.
- You have symptoms of depression or disordered eating.
A dietitian or nutritionist can help you create a tailored meal plan, and a doctor can run tests to rule out underlying causes.
🎯 Final Words: Gaining Weight the Healthy Way
Being underweight is not just about appearance—it affects your immunity, energy, mood, and hormonal health. But the solution isn’t about eating more junk food. It’s about giving your body what it truly needs: nutrient-rich food, physical activity, mental peace, and proper rest.
Treat your body with kindness, nourish it with care, and strength will follow.
