Have you ever started a diet plan just to find yourself back to your old ways within weeks, even days? Unfortunately I have. Here's a couple of tips that have helped me.
Stop dieting, Eat for your goals. Friedrich Nietzsche said “He who has a why to live for can bear almost any how.” The word "diet" makes me think of something restrictive and temporary. Don't think of your eating as a "diet" instead remember why you are eating this way...#GOALS
Fail to prepare and prepare to fail...MEAL PREP! There are many ways to prep your meals and all of them can be effective. Just don't skip the prep! Personally, I eat almost the same breakfast everyday, my lunches are often dinner leftovers from the night before and I cook dinner each night for my family. I make a dinner menu on Sundays and do my grocery shopping for the week. This way works for me and it may not work for you. The important thing is to make a plan.
Allow yourself "cheats". So this can definitely get out of hand. If you cheated several times a week you won't see any progress in your nutrition. But you also can't be perfect 100% of the time. Find a balance. Allow yourself to eat the foods you love by either working it into your macros or with a cheat meal. I try to allow myself one cheat meal a week. Not a cheat day, not a cheat weekend, ONE cheat meal.
Make small changes over time and you will see results that will last, no quick fixes. Consistency is more important than perfection.
