Why Prolinn could not make starvation safe
Prolinn was a liquid protein supplement built from hydrolyzed collagen—the protein in connective tissue, including skin, cartilage, and tendons. Processing breaks collagen into smaller pieces that can be mixed into a drink. It supplied protein, but collagen is not nutritionally equivalent to the varied proteins people get from foods such as eggs, dairy, or beans: it lacks tryptophan, an amino acid the body cannot make and must obtain from food.
That distinction matters when a supplement is treated as the mainstay of a diet. Protein is only one part of nutrition. The body also needs enough energy, essential fats, vitamins, minerals, and a balance of amino acids. A flavored liquid can make a restrictive plan easier to swallow without making it nutritionally complete.
The weight loss came from the restriction
When people consume far fewer calories than their bodies use, the body draws on stored energy, including fat. That deficit—not a special fat-burning property of the drink—explains why an extremely restrictive plan can produce weight loss. But severe restriction can also leave the body short of the fuel and nutrients needed to maintain normal function. Protein in the formula did not cancel out the consequences of eating too little overall.
The key distinction is between a supplement that contains protein and a diet that adequately nourishes someone. Prolinn’s cherry flavor could disguise the drink’s unusual ingredients; it could not change what the body needed. The plan’s weight-loss story was therefore inseparable from its central danger: deprivation was doing the work.
