How does thyroid dysfunction affect Basal Metabolic Rate (BMR)?
Asked by Aniket S., Mumbai
Dr. Ananya Vedavyas (PhD)
Certified Expert
Thyroid hormones (T3 and T4) directly regulate mitochondrial energy production. Hypothyroidism slows mitochondrial respiration, leading to a 15-30% reduction in BMR, causing fatigue and weight gain. Hyperthyroidism has the opposite effect, raising energy expenditure. Managing thyroid requires protein, selenium, zinc, and calorie-balanced planning.
Can fermented foods aggravate bloating or IBS symptoms?
Asked by Renu G., Pune
Dt. Ramashankar Shastri
Certified Expert
Yes. While fermented foods (kefir, kimchi, sauerkraut) provide beneficial probiotics, they are high in FODMAPs and histamines. If you have SIBO (Small Intestinal Bacterial Overgrowth) or active gut dysbiosis, these foods can feed pathogenic bacteria in the small intestine, triggering gas, bloating, and cramp flare-ups. A low-FODMAP phase is recommended first.
What is the optimal protein dosage and timing post-resistance training?
Asked by Vikram K., Delhi
Dt. Rajesh K. Sharma
Certified Expert
Clinical evidence indicates that consuming 20-40g of high-quality protein (rich in leucine, such as whey or soy isolate) within 1-2 hours post-workout maximizes muscle protein synthesis (MPS). Distributing total protein intake evenly across 3-4 hour intervals throughout the day is equally critical for optimal hypertrophy.
