Thermogenesis and calorie burning

Thermogenesis refers to the process by which the body generates heat. This process is a key component of energy expenditure and involves burning calories. There are several types of thermogenesis, including:

Basal Metabolic Rate (BMR): This is the amount of energy the body requires to maintain basic physiological functions at rest, such as breathing, circulation, and cell production. BMR accounts for the largest portion of total daily energy expenditure.

Diet-Induced Thermogenesis (DIT): Also known as the thermic effect of food, this refers to the increase in energy expenditure that occurs after eating. It includes the energy required for digesting, absorbing, and metabolizing nutrients. Different nutrients have varying thermic effects, with protein generally causing a higher increase in energy expenditure compared to carbohydrates and fats.

Physical Activity: Exercise and other physical activities increase energy expenditure by burning calories. The amount of calories burned depends on the intensity, duration, and type of activity.

Non-Exercise Activity Thermogenesis (NEAT): This includes all the minor movements and activities that are not structured exercise, such as walking, fidgeting, and even maintaining posture. NEAT can vary greatly among individuals and significantly impact total daily energy expenditure.

Adaptive Thermogenesis: This is the body's way of adjusting energy expenditure in response to changes in the environment, such as cold exposure or overfeeding. It involves both the activation of brown adipose tissue (which burns calories to produce heat) and adjustments in other metabolic processes.

Calorie burning is a result of these thermogenic processes. The balance between the calories consumed (through food and drink) and the calories burned (through BMR, DIT, physical activity, and other thermogenic processes) determines whether a person gains, loses, or maintains weight. Understanding these processes can help in developing strategies for weight management and overall health.

Rising Temperatures Spark Health Concerns: The Impact of Ultra-Hot Climate on Public Health

  As the mercury continues to soar, with temperatures hovering around 40 degrees Celsius for the past fortnight, concerns over public health are reaching a fever pitch. Weather experts are predicting an impending heatwave across Kerala, exacerbating the already scorching conditions. In the face of such relentless heat, people are turning to various cooling beverages for relief, with carbonated drinks and sugary juices topping the list of preferred choices. Taking note of the alarming situation, experts caution against excessive consumption of these beverages, particularly carbonated drinks, citing potential health risks such as fatty liver disease and other chronic conditions. The soaring temperatures, coupled with unhealthy drinking habits, pose a significant threat to public health, underscoring the urgent need for awareness and preventive measures. One of the common disease surges during this period is Jaundice cases attributed to the consumption of contaminated water. With hygiene

It's time to rethink on Your Morning Walk Routine in Areas marked with Poor Air Quality

  Living in an area frequently under the media spotlight for its negative air quality indexes prompts a critical rethink of your morning walk routine. While touted as a prime method to enhance agility and maintain overall health, recent studies from global experts issue a stark warning: proceeding with your morning walk sans precautionary measures, such as wearing masks, can escalate respiratory issues, especially for individuals with a history of COVID or respiratory illnesses. In the regions were the Air Quality Index (AQI) surpasses 300, during morning hours when temperatures are cooler, pollutants settle, intensifying their concentration. Engaging in a walk amidst such conditions risks inhaling a hazardous blend of polluted air. This exposure may trigger symptoms like coughing, shortness of breath, and escalate the likelihood of developing severe conditions like Chronic Obstructive Pulmonary Disease (COPD), cardiovascular diseases, and even lung cancer. In light of these findings,

കാളാഞ്ചി തവാ ഫ്രൈ

ഇന്ന് കൊച്ചിയിലെ നോൺ വെജിറ്റേറിയൻ ഭക്ഷണശാലകളിൽ ഏറ്റവും കൂടുതൽ ഡിമാൻ്റുളള ഒരു വിഭവമാണ് ഫിഷ് തവാ ഫ്രൈ. അതിൽ തന്നെ അധിക ആളുകളും താത്പര്യപ്പെടുന്നത് കാളാഞ്ചി തവാ ഫ്രൈയ്ക്കാണ്. ഇംഗ്ലീഷ് ഭാഷയിൽ സീബാസ് എന്നറിയപ്പെടുന്ന ഈ മീൻ കടലിലും കായലിലും കാണപ്പെടുന്നു. ഇതിൽ വിലയിലും രുചിയിലും ഒരു പടി മുന്നിൽ നിൽക്കുന്നത് കായൽ കാളാഞ്ചിയാണ്. വെറുതെയല്ല വില കൂടുതൽ എന്ന് സാരം.  ഇനി എന്തുകൊണ്ടാണ് കായൽ കാളാഞ്ചിയ്ക്ക് ഇത്ര രുചി കൂടാൻ കാരണമെന്ന് ചിന്തിച്ചിട്ടുണ്ടോ. കാരണം അതിൻ്റെ ഭക്ഷണരീതി തന്നെ. കായൽ കാളാഞ്ചി കൂടുതലും ഭക്ഷണമാക്കുന്നത് കായലിലെ ചെമ്മീനുകളെയാണ്, വെറുതെയല്ല ഇത്ര ടേസ്റ്റല്ലേ.ഉപഭോക്താവിനെ സംബന്ധിച്ചിടത്തോളം ഒരു വെടിക്ക് രണ്ടു പക്ഷി. കാളാഞ്ചി കഴിക്കാം ചെമ്മീൻ ആസ്വദിക്കാം.
