What should I eat??
When it comes to nutrition, it's definitely easy to get overloaded with contradicting information. Keto? Vegan? Paleo? Carnivore? People often become very dogmatic about certain ways of eating, when it works for them or someone they know. The truth is, there is not one way of eating that works best for EVERYONE.
There are many factors that determine if a certain type of eating is going to work for you. Lifestyle is a major one. Do you work sitting in an office all day? Or are you doing a physical job where you are moving all day? Your genetics are another major factor. Nowadays, there are lots of genetic tests that you can get done that show there are optimal ways for us to eat, depending on our backgrounds. Some react better to eating higher carbohydrates, some fats. These tests can be costly, so many choose to go through what's called an elimination diet. The idea is you take certain food groups, like dairy, out for a month, re-introduce them, and see how you feel and how your body reacts. If this interests you, you may want to check out The Whole 30.
There's also lots of information about WHEN you should eat. Intermittent fasting has been for popular in the health and fitness industry for some time now. It's the idea that you're shortening your eating "window." For example, you fast until lunch, and consume all of your calories between 12-8. The idea is that your body is spending a large portion of it's energy digesting food, and when you're spending less time eating, your body is able to go into repair mode, and allows for a process called autophagy, which is the process where your body removes damaged cells and replaces them with new ones. There is pretty good research behind fasting, and it's something that has been around for thousands of years, and has been missing in our culture. Just be sure to do your research so that you can do it in a safe way.
For me personally, I feel the best when I eat as little processed food as possible. Eating good sources of protein (beef, chicken), fruits, and vegetables. I feel fine consuming dairy, although it causes a lot of people issues. I work a physical job early in the morning, so I usually wait a couple of hours to eat, but feel fatigued if I wait longer than that. I make sure my first "meal" is light and nutritious. My best advice would be to play around with different ways of eating, and see what's best for YOU. If any of these "diets" interest you, do your research and see if it's something that might be a good fit for you. If you decide to experiment, give it time, ideally at least a month. Chances are, you'll see good results from just paying attention to what you're putting in your body, and you might just find the perfect way for you to eat.
