What is a protein-sparing modified fast?

A protein-sparing modified fast (PSMF) is a very-low-calorie diet that emphasizes lean protein and limits carbs and fats. It is designed for short-term, rapid weight loss while trying to preserve lean muscle. It was originally developed in clinical settings under supervision.

Can you really lose 14 pounds in 2 weeks?

Some people can lose that much on the scale in two weeks under an aggressive protocol, but a meaningful portion of the change is water, glycogen, and gut content rather than pure body fat. Sustainable fat loss is usually slower and more durable.

Is rapid weight loss safe?

It depends on the person, the protocol, and the supervision. Aggressive very-low-calorie diets are not appropriate for everyone and can be risky for people with medical conditions, on medication, or with a history of disordered eating. Talk to a qualified healthcare professional first.

You can lose some lean mass on any deficit. High protein, strength training, and adequate sleep help protect muscle. Very deep deficits with poor training and poor sleep tend to cost more lean mass than smarter, slightly slower approaches.

Can I do CrossFit or HYROX on a very-low-calorie diet?

You can train, but performance usually drops, recovery slows, and injury risk can rise. Most CrossFit and HYROX athletes do better on a moderate, structured cut with enough carbs to support training quality.

What should I do instead of a crash diet?

Use the 14-Day Strong Reset: protein at every meal, 8,000 to 12,000 steps daily, three strength sessions per week, two CrossFit or HYROX conditioning sessions per week, two-plus litres of water, seven-plus hours of sleep, mostly whole foods, and no alcohol for 14 days.
