The speaker, Frank Suárez, a specialist in obesity and metabolism, explains that losing weight without leaving hanging skin is possible by following four rules:
1. **Perfect hydration**: Drinking enough water to keep the skin flexible and able to return to its original shape. The recommended amount is calculated by dividing one's weight in kilograms by 7 (or pounds by 16).
2. **Not going hungry**: Losing weight without going hungry, as hunger can lead to stress, which causes the body to produce cortisol, a hormone that breaks down muscles, leading to hanging skin. The speaker recommends the "3-for-1 diet," which allows for a balanced intake of foods that don't produce glucose or insulin.
3. **Eating according to one's nervous system type**: People with an "excited" nervous system should eat a diet that doesn't stress their body, such as white meat, fish, vegetables, and low-fat cheeses, while avoiding red meat and pork.
4. **Taking flaxseed oil**: Consuming a tablespoon of flaxseed oil daily, which is rich in omega-3 fatty acids, can help prevent the skin from losing elasticity and reduce the risk of stretch marks and hanging skin.
By following these four rules, individuals can lose weight without damaging their skin and achieving a healthier, more toned appearance.
