Evaluating Resting Metabolic Rate Findings
I recently underwent a resting metabolic rate assessment at a health science facility. The lab director expressed strong confidence in the results, which I found somewhat unsettling before the evaluations began. However, after careful consideration and analysis, I cannot accept the findings as accurate. To provide some background, I am a 33-year-old male weighing 88 kilograms and standing at 185 centimeters tall. According to the test results, my resting metabolic rate was calculated at 900 calories per day. Based on my research, this figure appears significantly lower than anticipated—it should realistically be at least twice that amount. Additionally, I have successfully lost approximately 10 kilograms over the past five months by incorporating increased physical activity and embracing a more active lifestyle. I am not experiencing any low energy levels and my cardiovascular fitness is quite good. Could anyone share their thoughts on this matter? I also had two tests generate comparable results from the same laboratory.

It's understandable to feel unsettled about a resting metabolic rate (RMR) result that seems significantly lower than expected, particularly given your active lifestyle and weight loss. Here’s an overview of your situation: you are a healthy, active 33-year-old male weighing 88 kg and standing 185 cm tall. The reported RMR of 900 calories per day appears unusually low, which raises questions about the assessment's accuracy.
Explanation:
Your RMR is the number of calories your body needs at rest to maintain basic physiological functions. Factors influencing RMR include age, sex, muscle mass, and physical activity levels. For someone with your profile, typical RMR values are often between 1,600 to 2,000 calories per day, depending on various factors.
Here are some points to consider regarding the testing process:
- Accuracy of Measurement: RMR assessments can vary due to factors like hydration status, stress, current health status, and how well the testing protocol was followed (e.g., fasting requirements).
- Metabolic Adaptation: Having lost weight could potentially affect your metabolism, though not typically to the extent of producing such low RMR values.
- Individual Variability: Every person's metabolic rate is unique, and occasional anomalies may occur due to specific health conditions or testing nuances.
Next Steps:
- Re-evaluate Results: If possible, consider undergoing another RMR assessment at a different facility. This may provide a more reliable comparison.
- Monitor Your Energy Levels: Continue to observe how you feel day-to-day; maintaining your energy and fitness levels is a positive sign.
- Diet and Activity Review: Ensure your nutritional intake meets or exceeds 2,000 calories daily through a balanced diet that includes protein, carbohydrates, and healthy fats.
- Consultation for Clarity: Consider seeking advice from a registered dietitian or a qualified nutritionist to better analyze your metabolic needs and dietary approach.
Lastly, remember that while data is important, your personal experience and health status should take priority. Engaging with professionals can help clarify any misconceptions and align your plans with your health goals. Let me know if you have any other questions or concerns!

Challenges with My Left Side
I've been experiencing a troubling sensation in my left thigh; it feels both numb and tense, which becomes apparent even when I’m simply walking. There are various spots within my left quad that intermittently lose feeling, and sometimes I find myself instinctively punching my thigh to alleviate the discomfort. During leisurely walks in the park, I often catch myself tugging at my hamstrings, coming to a realization about how little muscle mass I possess there. Particularly, I notice the tightness in my hamstrings and core while just standing or studying. My abdominal muscles feel peculiar and lack strength; during exercises like leg raises, it becomes evident how small and tight my hamstrings are. Additionally, I’ve observed that my glutes have a tendency to shrink in size, contributing to a lack of mass. This combination of underdeveloped glutes and hamstrings leaves me quite aware of the weakness and tightness, especially in the heel and left glute area. My hamstrings feel incredibly tight and feeble. Right now, as I'm seated in the car, there's this weightless sensation in my hamstrings; they feel almost nonexistent and extremely taut. I can sense that my entire left side feels off balance. Even when walking through the grocery store, my left heel feels unusual and contributes to the overall sense of physical discomfort on my athletic side. The reality is, my glutes are quite small, and my hamstrings are noticeably weak. This condition is a significant concern for me, as it impacts my daily life in a rather uncomfortable way. I find myself feeling distressed about it, especially since the situation is escalating to a severe level, and at just 22 years old, I'm unsure of the cause of these issues.
Continuous Burping for Five Consecutive Days
Hello, I’m a 20-year-old male experiencing persistent burping for the last five days. This issue is not only uncomfortable but has also led to chest pain due to the strain caused by the excessive burping. Although I've visited the hospital for assistance, the doctors could not determine the cause of my symptoms. The burping episodes can last anywhere from four to five hours, with only brief intermissions of about an hour before resuming. My eating habits have drastically changed; I’ve gone from consuming just one meal a day to ingesting between 2,000 and 2,500 calories daily. The situation is affecting my ability to sleep and manage everyday activities due to these constant episodes. Is there anyone who can provide advice or assistance with this troubling condition?
Struggling with My 24-Hour Urine Test
At 22 years of age, I'm feeling overwhelmed by the 24-hour urine test my doctor ordered to check my cortisol levels. Despite my attempts to prepare—hydrating with water, tea, and even warm beverages—I find myself unable to collect enough urine. Each time I go, I can only manage a tiny amount, leading to my growing anxiety that the results will be inconclusive or entirely empty. My mom reassures me that it's not something to stress over and that it’s not my fault, but I find myself questioning whether I should even continue. I began the collection around 5 in the morning, and now, roughly 12 to 13 hours later, I am struggling to even reach the first mark on the container. Is this effort really worth it? I'm looking for advice or others' experiences to determine if pushing through this challenge is the right move for me.
F24 Unexplained Red Mark on My Forehead
