Two things:
- Why remove naturally occurring fat from a food? If to lower calories, why not remove total quantity of food, and fat in its natural proportion? Here's a fact: humans NEED dietary fat to survive. We don't need dietary carbs.
- When we remove fat, what is replacing it?
- Kirby64 2y agoThe amount of dietary fat needed for humans to survive is very small. Most studies I’ve seen suggest the amount is close to 30-50g/day (depending on your weight) before there’s any meaningful long term health problems. Dietary carbs are extremely valuable for energy purposes. Sure, you can be a keto nut and go completely no carbs, but extra carbs is valuable for energy reasons. That said, ideally you should be replacing fat with more protein. Most folks get far far too little protein in their diet, and protein is necessary for maintaining and gaining muscle mass, which has a huge impact on obesity and body form. If you don’t have enough protein to maintain muscle mass but have excess calories then literally the only place for it to go is into fat stores…
- hilux 2y agoI'll emphasize it again: dietary fat is essential. Dietary carbs are not. You can live forever on zero carbs. Therefore it's extremely unlikely that carbs are more "valuable" than fat. Whether "extra calories" go to fat or are burned, is determined by your level of insulin. You can google this. As a starting point, I recommend any video or blog post by Dr. Jason Fung. Eating a high protein diet is difficult to do, and also hard on the kidneys. It may work for teenagers and twenty-something males who want to unnaturally bulk up. It is not healthy for long life.
