reason:
Consuming a diet is recommendable that includes adequate protein which is important for building and maintaining lean body mass. Protein is essential for muscle growth and repair. Including lean sources of protein, such as lean meats, poultry, fish, eggs, dairy products, legumes, and nuts, can support weight loss while helping to preserve and build lean muscle tissue.

reason:
Eating snacks three times a day is not recommendable. While regular meals and snacks can help regulate blood sugar levels and prevent overeating, simply eating snacks three times a day without considering the overall quality and composition of the diet may not necessarily result in healthy weight loss or lean body mass gain.

reason:
Supplementing with dietary shakes is not recommendable. Dietary shakes can be a convenient way to supplement nutrient intake, but they should not replace whole foods. Depending solely on dietary shakes may not provide the full spectrum of nutrients needed for overall health and optimal weight management.

reason:
Performing aerobic exercises 20 to 30 minutes is not recommended
Aerobic exercises are beneficial for cardiovascular health and burning calories, but building lean body mass often requires incorporating resistance or strength training exercises. Strength training helps stimulate muscle growth and development
