My advice is not to think in terms of "being on a diet" but in terms of "what does healthy eating look like." I know at least for myself, I've spent so many years counting calories or doing fad diets, and I'm burnt out on the tracking and the counting, and feeling deprived and waiting for it to be "over." What I've started doing instead is focusing on what healthy eating really looks like and trying to choose mostly the good things and eliminating the bad things. For example, I've started having a smoothie every morning with 2 oz spinach, plain Greek yogurt, unsweetened almond milk, frozen fruit, chia, flax, and hemp seeds, and protein powder. I know that everything in it is great for fueling my body and I feel good about drinking it. At lunch, I have a massive salad. Like, I bought a serving bowl and I fill it to the top with spring mix, spinach, shredded carrots, cucumbers, tomatoes, cabbage, beets, and mushrooms. I put about 3oz chick peas and black beans on it, and 2-3 oz lean deli meat, plus a Tbsp each of pumpkin seeds, sunflower seeds, and sliced almonds. I top it with a freshly squeezed lemon and Tuscan seasoning blend instead of dressing. I'll be honest, the thing is so filling I barely have room for dinner. I do eat dinner, but it's light and mostly protein and veg. Since I've started doing that and gotten all the snacks out of the house (no more buying pretzels, crackers, and other easy carbs or sweets) and only allowing myself fruit or nuts for a snack, I haven't really felt hungry at all, and I haven't been craving junk like I used to. I've also cut back on caffeine and stopped drinking diet sodas. I started making these changes in July and I'm down almost 15lbs without having to write down everything I do, because it's mostly the same every day. For me, this is something I can keep up long term as long as I am mindful of what I allow myself to bring into the house. Give yourself time, you can do it!
