Portion the perfect plate
Each meal should consist of 45 percent fiber-rich carbohydrates, 30 percent healthy fats, and 25 percent lean proteins, such as white-meat chicken or turkey, fish, tuna, tofu, beans, or egg whites, Rosenstock says.
Eat before hunger strikes
A good way to make sure you don’t end up reaching for chips or a chocolate bar when you need a snack is to eat before you feel famished.
Shop smart
Of course, it’s hard to completely part with packaged foods. But you can incorporate them into your diet if you stick with those that contain minimal ingredients.
Have healthy foods around
It may sound obvious, but, as Rosenstock advises, stocking your fridge and pantry with ready-to-eat healthy foods means you will be less likely to reach for bad stuff.
Drink water
Keeping yourself hydrated not only helps maintain proper kidney function and avoid dehydration, which can lead to fatigue, but it can also aid in healthier eating.
Avoid beating yourself up if your healthy eating mission becomes derailed by so-called bad food like a slice of pizza or a jelly doughnut. Do not let one meal define the rest of their day or the rest of their week.
