Unexplained weight gain can be puzzling and concerning. There are a few potential causes to consider if you notice your weight increasing significantly without clear lifestyle or dietary changes:

  • Hormonal imbalances - Issues with hormones like cortisol, estrogen, testosterone, and thyroid hormone can lead to increased appetite, fluid retention, and metabolic changes that promote fat storage. See your doctor to get tested.
  • New medications - Some prescription drugs list weight gain as a common side effect. Check with your healthcare provider if any new medications could be contributing.
  • Underlying illnesses - Problems like diabetes, polycystic ovarian syndrome (PCOS), Cushing's disease, and hypothyroidism can cause stubborn weight gain. Getting the right diagnosis is key.
  • Aging - As we get older, hormonal shifts and loss of calorie-burning muscle mass create metabolic headwinds. Focus on nutrition, exercise, sleep, and stress reduction.
  • Lifestyle habits - Subtle things like poor sleep, high alcohol intake, a sedentary job, or long commutes can promote insulin resistance, inflammation, and weight gain over time. An audit of daily habits could uncover some areas to improve.
What should you do about unexplained weight gain? Getting to the root cause with thorough lab testing and a physical exam is key. Based on the findings, treatment plans can range from lifestyle and nutrition changes, oral or topical medications, supplements to support hormonal balance, lowering inflammation, correcting insulin/blood sugar irregularities, stress and sleep interventions, increasing activity, etc. Having an open dialogue with your healthcare provider and registered dietitian can uncover the most likely culprits and appropriate solutions. Patience and consistency will be important when implementing the advised protocols too. Here are some proactive tips as well:
  • Track calories for a few weeks to quantify intake
  • Reduce highly processed foods, sugary items, and refined carbs
  • Increase consumption of high-fiber whole foods - fruits, vegetables, legumes, whole grains
  • Stay well hydrated with water and herbal teas
  • Aim for 7-9 hours of quality sleep per night
  • Incorporate more movement each day, like taking the stairs or going for walks
  • Manage stress levels with meditation, yoga, massage, or talking to a therapist
  • Consider an elimination diet to uncover food sensitivities
Unexplained weight gain can be stressful and hard on self-confidence. But with a methodical approach, the right medical guidance, consistent lifestyle habits, patience, and self-compassion, you can get to the bottom of what's causing it and improve your health.
