Keto style diets made a huge impact on my life. I will say this though: it's very difficult to eat low-carb in America. While I was overseas in the South Pacific, there were a lot more low carb options and produce was of higher quality. Here in American, everything is loaded with sugar and I've had to cook a lot more of my own food if I want to stay healthy. But I agree, cutting out sugars/starches greatly changed things for me. Have a Steak and Salad instead of a Steak and Fries. For breakfast, just have the bacon and eggs and skip the toast. It makes a massive difference.
