Metabolic Role of Fat Versus Skeletal Muscle

“Visit MRC Melbourne to Learn More About Boosting Metabolism Naturally”

Muscle is more metabolically active than adipose tissue. Since muscle and fat differ in density and not weight, one pound of muscle and one pound of adipose body fat weigh the same, but muscle mass takes up less space and naturally gives your body composition a leaner look. Muscle powers movement, while fat is less dense and provides for energy storage. Plus, skeletal muscle burns three times more calories per pound than fat each day.

While your body has several types of adipose tissue (subcutaneous, visceral), fat is generally stored as subcutaneous deposits in the upper body, legs, hips, and thighs. But, more harmful deposits of visceral are stored much deeper, usually surrounding internal organs in the midsection, and directly impacts the body’s liver function. Nonetheless, adipose tissue stores dietary fat from the meals you consume and release fatty acids, when your body needs a burst of energy.

According to experts at Harvard Health, one of the best ways to maintain metabolic wellbeing throughout your 20s and beyond is to remain physically active with strength training or exercises using resistance bands. Maintaining skeletal muscle plays a key role in how your body processes glucose, which makes it a powerhouse for supporting metabolic efficiency. As adults age, they naturally lose lean muscle tissue, especially in older women, which reduces mobility and hinders daily metabolic regulation.

Is the increase in fat with age uniform in men and women?

As the human body ages, both men and women go through changes and the way their bodies store fat is no exception. Fact is body fat doesn’t just increase; it shifts where fat deposits are located. Specifically, older adults tend to accumulate more "central" fat, such as visceral fat around the organs and upper body fat, rather than storing it evenly throughout the body. Not surprisingly due to hormonal variations, these fat deposits look a bit different for men versus women. Older women, for instance, have about 300% more visceral fat than younger women, but only slightly more fat in their upper bodies and legs. On the other hand, older men have over twice as much visceral fat as their younger counterparts, with a slight increase in upper body fat and no extra fat in their legs. Moreover, while men experience a natural decline in testosterone as they age, women see hormonal drops in their 40s and 50s, particularly during menopausal phases. In both sexes, DHEA hormone concentrations steady decline with aging.

CORE PRINCIPLES FOR PERSONALIZING METABOLIC MENUS

Personalizing a metabolic menu plan involves prioritizing a protein-forward diet that includes sources of lean protein and low-carb whole-food intake, while structuring meals and snacks to better manage blood sugar levels and tailoring macronutrients ratios to the individual’s activity levels and metabolic goals. So to more effectively support your need for long-term weight control, focus on these foundational strategies:

1. Prioritize Protein: Starting your meal or snack with the first couple of bites being protein helps to stabilize your body’s insulin response. So, aim for 20 to 30 grams of high-quality protein per meal. Since protein has a high thermic effect of food (TEF), it means your body naturally burns more calories processing protein than fats or carbohydrates.
2. High-Fiber "Smart Carbs": Choose slow-digesting carbohydrates like oats, lentils, and berries to naturally help prevent insulin spikes that can trigger the body to store excess energy as fat. Based on your body’s unique needs, consider loading half your plate with non-starchy vegetables that slow digestion, increase fullness, and feed your gut’s microbiome.
3. Metabolism Boosters: Incorporate foods known to naturally support metabolic rate, such as green tea, coffee, chili peppers containing capsaicin, and iron-rich leafy greens. These foods naturally enhance your metabolic rate through the thermic effect of food (digestion) and their high nutrient content that aids in energy production.
4. Consistent Hydration: Drinking water, especially before meals, can temporarily boost metabolic rate and help with appetite control. But, it is essential to drink enough water or green tea throughout the day to support key cellular processes. Fact is water boosts metabolism by initiating thermogenesis, while dehydration slows your metabolic rate.
5. Avoid "Naked Carbs": Always pair carbohydrates with a protein or healthy fat to slow down your body’s rate of sugar absorption. Plus, opt for complex carbohydrates (non-starchy vegetables, low-carb whole foods) over baked goods, refined sugars, and overly processed sources of protein to prevent unwanted blood sugar spikes.

Finishing food intake, whether it is your late meal or snack, early in the evening and a couple of hours prior to bedtime can improve fat oxidation the following morning. Some experts recommend eating at least three meals a day with a five-hour fast between periods of food intake to naturally allow your insulin levels to drop. Generally speaking, both how and when you eat may be just as important as what you eat, when it comes to improving metabolic wellness.

Muscles are a major consumer of your body’s calorie intake each day and burn energy even when you’re resting. So a healthy percentage of muscle mass helps to keep your metabolism churning. However, almost without notice, your body can become more energy-efficient by burning fewer calories for the same activities to save its fat stores based on perceived starvation due to metabolic adaptations. If you’re trying to decide whether a prescription-based weight loss plan or a more holistic metabolic weight loss program is right for you, contact MRC Melbourne today. One of our weight loss coaches will be in touch to discuss how hormone imbalances, genetic factors and key lifestyle habits may have slowed your metabolism and led to unintended weight gain. After all, hormonal balance can be restored and disrupted metabolic rates can be reset with a personalized approach.
