Beef not only avoids making you gain weight but also offers many benefits for managing overweight and obesity, provided you choose the right type of beef and prepare it properly.

A shimmering blue, purple, or rainbow-like sheen on beef, often mistaken for spoilage or chemical treatment, is typically a natural optical phenomenon and not a sign of unsafe meat, according to experts.

To avoid buying fake beef, consumers can check by touch, observe its color and muscle fibers, test it with clean water, or rely on its distinct flavor when cooked.
