<ul><li class="ql-align-justify"><a href="https://www.forbes.com/health/body/resistance-training-without-weights/">Resistance training</a>, which increases muscular strength and endurance by exercising those muscles against external resistance, is vital for both fat loss and muscle gain. </li><li class="ql-align-justify">Resistance training can be performed by using elastic fitness bands, which are rubber elastic bands that you stretch by exerting force, strength training machines and weights like barbells, dumbbells and kettlebells.</li><li class="ql-align-justify">The key is to take reps to muscle fatigue.

The Best Type of Workout to Lose Fat and Gain Muscle

Research suggests most adults should consume 1.5 grams of protein per kilogram of body weight per day and pair that dietary lifestyle with resistance training to build muscle efficiently. However, this amount may vary based on an individual’s age, calorie intake and body weight.It’s necessary to include high-quality protein sources in the diet - leucine, an amino acid typically found in higher amounts in animal-based proteins, can help stimulate muscle gain. Protein sources high in leucine include:<ul><li class="ql-align-justify">Chicken</li><li class="ql-align-justify">Fish</li><li class="ql-align-justify">Eggs</li><li class="ql-align-justify">Milk</li><li class="ql-align-justify">Dairy products, such as yogurt and cheese</li></ul>

Optimal Protein for Losing Fat and Gaining Muscle

For individuals who follow a plant-based lifestyle, it is recommended to costume a variety of plant proteins, including plant-based protein powders, such as pea-based products, that are typically high in leucine. Plant sources of high-quality protein include:<ul><li class="ql-align-justify">Legumes, such as beans, chickpeas, lentils and soybeans</li><li class="ql-align-justify">Nuts</li><li class="ql-align-justify">Seeds</li><li class="ql-align-justify">Tofu</li><li class="ql-align-justify">Tempeh</li></ul>Speak with a health care provider before increasing protein intake. Excessive protein consumption or a macronutrient imbalance in a person’s diet may worsen symptoms of certain conditions, such as kidney disease and diabetes.

Plant Based 

<ul><li class="ql-align-justify">When setting weight loss goals, it’s important to focus not only on losing fat, but also on retaining muscle mass. </li><li class="ql-align-justify">Skeletal muscle supports the body’s structure and generates essential movements, such as walking, personal grooming and eating.</li><li class="ql-align-justify">Unintentional muscle loss can affect other aspects of health as well, including bone health, heart health and longevity.</li><li class="ql-align-justify">Alternatively, gaining muscle not only minimizes these risks, but also contributes to calorie burning (even at rest) since muscle is denser and more metabolically active than fat.</li></ul>

Retaining Muscle Mass as Part of Weight Goals 

<ul><li class="ql-align-justify">Weight loss of 0.5% to 1% (or about 1 to 3 pounds) of body weight per week is [generally considered] safe,” notes Chavez.</li><li class="ql-align-justify">Body fat loss beyond that amount can have negative health implications, such as a slower metabolism, bone density loss and menstrual irregularities and can lead to increased food cravings and disordered eating , he cautions. </li><li class="ql-align-justify">Most scales only gauge total body weight and don’t show how much of that weight is fat versus muscle.</li></ul>

Recommended Weight Loss 

There are 4 helpful ways to <a href="https://www.forbes.com/health/body/body-fat-calculator/">measure body fat</a>:<ul><li>Skinfold measurements, measure with calipers and plugged into an equation that calculates body fat.</li><li>Bioelectrical impedance scales, measure body fat, muscle mass and water percentage through the use of painless electrical currents.</li><li>Hydrostatic weighing, measure body fat through how much water is displaced when you’re submerged in water.</li><li>Dual energy x-ray absorptiometry (or DEXA) scan, x-ray that captures images and determines body fat and muscle mass.</li></ul>Taking pictures every 4 to 6 weeks to visually catalog progress is also recommended.

How to Measure Fat Loss

Modest weight loss can lead to health benefits and lower a person’s risk of chronic diseases like <a href="https://www.forbes.com/health/body/type-1-diabetes-vs-type-2-diabetes/">diabetes</a> and heart disease.

Potential Health Benefits of Fat Loss

Muscle is essential for functionality, and building and maintaining muscle mass throughout life is associated with longevity. In fact, progressive <a href="https://www.forbes.com/health/healthy-aging/muscle-strength/">muscle loss in older adults</a>, or sarcopenia, is linked to an increased risk of falls, disability and death.A 2021 study in Nutrients cites the following potential benefits of muscle gain:<ul><li class="ql-align-justify">Increased strength</li><li class="ql-align-justify">Increased ability to perform daily tasks and activities</li><li class="ql-align-justify">Increased metabolic rate</li><li class="ql-align-justify">Decreased injury and fall risk</li><li class="ql-align-justify">Improved blood sugar metabolism</li></ul>

<ul><li class="ql-align-justify">When doing a chest press on a machine, if you’re pushing out the handles on your eighth repetition, but you make it a third of the way out, you’ve reached muscle fatigue and completed seven reps. </li><li class="ql-align-justify">By practicing reps, you engage the maximum amount of muscle fibers. </li></ul>This engagement stimulates both muscle growth and insulin sensitivity, which promotes fat loss.
