Staying away from sugars and limiting carbohydrates (around 30g of carbs per day since it's nearly impossible to go NO carbs - I eat veggies and nuts) immediately forced me to stop eating just about anything processed. Even a granola bar has 20 or 30 grams of carbs and god knows what else is in there.
Key things are:
Here is a typical day for me when it comes to food.
I normally skip breakfast and all I have before lunch time is 1 cup of nuts and 2 cups of green tea. At lunch, I will treat myself to something high in fats and 30-40g of protein. This is normally a salad with a ton of olive oil and/or caesar dressing with meat (usually steak, chicken, or bacon) on top. Or I might change this and do something similar to a stir fry made up of things like broccoli, onions, mushrooms, carrots, and meat. My goal is to load up on nutrients from veggies while still getting a good amount of fats and protein. Between lunch and dinner I will have another 2 cups of green tea.
Sidenote: This green tea gets me through a day at work in the office rather than energy drinks. I found taking a 10 minute walk after lunch also helps.
For dinner, I will usually have a similar meal to dinner - a large salad with meat, stir fry with plenty of veggies and meat, or I might do a 4 egg omelet with things like spinach, onions, bacon, and cheese. Yum.
Another common snack I'll have is 2 small squares of dark chocolate (70% cacao or more). I limit this to once a day and it changes what time of day.
