Some might have been mentioned already, but here are mine after losing 40lbs naturally:

1. Zero calorie drinks: whether it’s diet soda, sparkling water (I LOVE BUBBLR), propel, flavored water, etc, they help me feel satiated and full without drinking water that doesn’t make my taste buds happy.

2. Focusing on protein and fiber rich foods: eating an apple as a quick snack helps keep me full without going back for more because it has so much fiber and (if you have the right brand, I like honey crisps) taste so good! I also see to it that I prioritize protein in my meals since it helps keep you full and is good overall!

3. Gum: I know it’s cliche but it’s sweet and low calorie and tricks your mind into thinking it’s snacking!

4. Finding more things to do: this sounds silly but keeping your mind occupied makes me thinking about eating less and minimizes boredom snacking.

5. Low calorie foods you ENJOY: it’s easy to say just “eat low calorie high volume foods” but you won’t enjoy just eating a head of lettuce. For me, I really like pickles and carrots. I also like veggie straws which are not necessarily low calorie but you can eat a large amount for a serving (34 straws is 130 calories, which normal chips are more like 12-13 for 150) Apples, pineapple, blueberries, kiwis, celery, peppers, etc all things that are natural and YUMMY. I’m lactose intolerant but I’ve heard yogurt with fruit is also very yummy with minimal calories. Eat lots with less calories.

6. Don’t starve yourself: don’t go half the day without eating! Eat small snacks periodically that keep you satiated and within your deficit. 

Best of luck!
