Don’t define your eating style as one way and one way only. Neither low carb, ketogenic diet is really built for the long haul, and neither is veganism. It’s temporary action which builds temporary results.
The main thing with diet and exercise is, we’re all unique. In fact, you don’t have to define yourself in general. No matter how many words you use, you’ll always be missing something and your theory won’t be accurate.
The basic premise a severely overweight person needs to know is that calories in vs calories out is the main thing. You have to be in a caloric deficit to lose weight. The easiest way to reduce calories is to reduce sugar. And if you keep protein high at every meal, your muscles won’t atrophy as you reduce in weight. My idea of high is like 30 grams at each meal, nothing crazy.
You should also plan your day around regular meals at regular times. 9am, 12 noon, and 5pm is the best. Sometimes you can sneak in the mysterious fourth meal at night. Try not to graze all day long. That’s not good for your blood sugar or your pancreatic enzymes, which are limited.
In Spain, as in many European countries, people eat and drink light during the day, and on the way home from work, they stop by the food market or farmer’s market to buy what they will cook that night. This is truly natural living, to integrate work, sleep, rest, play and eating into one cohesive lifestyle.
Americans are not so lucky in that sense. They don’t get to have a leisurely, harmonious life. It seems like their priorities need working on. But I digress.
