So eat well and eat balanced. Know yourself and find out how you thrive. No one thrives on candy bars alone, so cut it out.
This is what I like to eat:
Breakfast: Greek yogurt with blueberries, walnuts and honey
Morning Snack: Apples with peanut butter and Nutella
Pre lunch snack: melon wrapped with prosciutto, Italian dry salami on the side.
Lunch: Cuban black bean, spinach, salsa sandwich on lavash
Afternoon snack: Cottage cheese with peach, spiced toffee almonds, and walnuts.
I also go to the gym every other day and squat, deadlift, row, press, overhead press, curl, extend, and crunch. I would have a hard time keeping weight on me. Others have a problem keeping weight off, and I envy you. I just happen to prefer good food, and it's hard to keep good food prepared for every single meal, every single day. I would rather not eat than eat something absolutely terrible for me (except doughnuts, I reeeaally like doughnuts). So eating less is natural for me. No matter what your life goal is, it will take effort to get there.
If you have to eat less, make sure every meal is awesome. If you have to eat more, make sure every meal is awesome. Embrace a natural love for food.
