I think it is linked to that recent ridiculous EAT Lancet report funded by billionnaire donors who want everyone to turn vegan
.
I personally found that limiting carbohydrates, particularly all processed carbohydrates, sugar, starch and grains, enabled me to finally kick obesity to the kerb three years ago. For good, i.e. I am maintaining a 100lb fat loss as a result of doing this. Other side effects include great digestion now, no bloating, and no sleepiness after meals, and even better, normal stable insulin levels.
That meant increasing animal proteins and fats and the side effect from doing this was I naturally began eating less (didn't need to break my fast until lunchtime, for example, as not hungry) and didn't need to snack in between meals any more.
So, I have found that red meat (and fish and eggs) has helped me cure my obesity, not caused it. What is going on with demonising red meat, and lumping it in with "processed meat" whatever that is. I don't eat "processed meat" and prefer a nice juicy rare steak.
