Is a Daily Intake of 800 Calories Sustainable for Weight Loss for a Sedentary 31-Year-Old Woman?
Weight: 112 lbs | Total Daily Energy Expenditure (TDEE): 1,346 | Basal Metabolic Rate (BMR): 1,160 At 31 years old and measuring 5'1", my lifestyle is predominantly sedentary due to my remote work arrangement. My work commitments consume most of my day, leaving little room for any physical activity. My meals largely consist of fish, eggs, rice, vegetables, and fruits, with a particular emphasis on fish, eggs, and vegetables. Additionally, I do take vitamins, although I'm uncertain about their overall impact on my health. In a few months, I expect to have more free time, allowing me to increase my physical activity and caloric intake. However, for now, I'm contemplating whether it would be appropriate to maintain a daily intake of around 800 calories, supplemented by 1-2 days where I might increase my intake to 1,000-1,200 calories. While many caution against low-calorie diets below 1,200 calories, I find that much of this guidance feels generic, especially considering my smaller stature and build.

A daily intake of 800 calories is generally too low for sustainable weight loss, even for someone with a smaller stature. While your TDEE (Total Daily Energy Expenditure) is 1,346 calories, consuming significantly below this level could lead to nutrient deficiencies and other health issues over time.
Explanation
Your Basal Metabolic Rate (BMR) indicates the number of calories your body needs at rest to maintain basic physiological functions. An intake of 800 calories is likely insufficient to support your metabolism and daily activities, especially considering you may have a sedentary lifestyle. Diets too low in calories can result in fatigue, nutrient deficiencies, and can negatively impact your metabolic rate.
Next Steps:
-
Increase Caloric Intake: Aim for at least 1,200 calories daily. This provides a safer margin that helps ensure you receive adequate nutrients.
-
Balanced Nutrition: Focus on including a variety of foods in your diet. Prioritize whole foods such as lean proteins, whole grains, healthy fats, and a wide range of fruits and vegetables to meet both your caloric and nutritional needs.
-
Monitor Your Health: Pay attention to how you feel physically and mentally. If you notice fatigue, irritability, or other negative symptoms, it may indicate that your diet is lacking in essential nutrients.
-
Future Activity: Since you expect to have more free time for physical activity, consider planning for that now. Even small adjustments, like short walks or stretching breaks during work, can make a difference.
-
Vitamins and Supplements: Continue with your vitamins, but it's a good idea to consult a healthcare provider to ensure they are appropriate for your individual needs.
Making gradual, sustainable changes will assist in achieving long-term weight management and overall health. If you have any further questions or need guidance on food choices, feel free to ask!

Is an 85-pound Weight Healthy for a Woman Who is 5’1"?
A friend of mine stands at 5 feet 1 inch tall and has a delicate frame, tipping the scales at 85 pounds. At first glance, her weight seemed surprisingly low, but I realized she doesn’t appear overly thin. Naturally, I became a bit worried as I believed her weight might be below the healthy range; however, she insists that she feels perfectly fine. She maintains an active lifestyle, exercising regularly and following a nutritious diet, yet she doesn't overindulge. This leaves me pondering whether her health is indeed in check.
Persistent Need to Stretch Legs While Seated
I experience a significant discomfort when seated, particularly when my knees are bent at about a 90-degree angle. This sensation compels me to stretch my legs straight, and if too much time passes without doing so—typically around every five to six minutes—the urge intensifies to an uncomfortable level that’s hard to manage. It’s more than just a desire to fidget; fully extending my legs tends to offer the greatest relief. Adjusting my position provides some comfort, but it doesn’t alleviate the feeling nearly as effectively as a full stretch does. This issue predominantly arises when I remain stationary in a chair. Occasionally, I notice a similar feeling when I’m lying down, but these instances are relatively rare compared to the frequent occurrences while sitting. I consulted a relative who is a medical professional about this discomfort, and they suggested that it doesn’t appear to align with Restless Leg Syndrome. However, since this isn't their specialization, I acknowledge that there may be a chance of error. * What could potentially be causing these sensations? * Does anyone else relate to this experience? * Are there methods available to help manage or diminish this feeling? I would greatly appreciate any advice or insights.

Combining Ketorolac with Alcohol: Is It Safe?
Recently, I unknowingly mixed a 10mg dose of ketorolac with half a bottle of 4.5% beer. At that moment, I wasn't aware of the potential risks involved in this combination. It wasn't until I was partway through my drink that I thought to look it up. Now, I’m wondering if it’ll be fine for me to have a drink tomorrow night after stopping all ketorolac use, especially since this medication hasn’t been effective for my pain relief. To give you an idea of the timeline, I took ketorolac around 2 PM and didn’t start drinking until 11 PM.
