Optimizing your diet is one of the low-hanging fruits (no pun intended).

Cut out anything with low nutrient density: chips, anything with more than a few g of sugar, stuff loaded with palm oil or other added saturated fats. High fiber fruits and nuts like raspberries, apples, kiwi, almonds and walnuts are good snacks.

Low carb, keto, mediterranean-whatever floats your boat-more important is: try to buy fresh, whole, local foods and high quality spices. Use them to prepare meals yourself if you have time. They will taste better and will be more satisfying.

Do some exercise every day. Even if it's just 15 minutes of pushups & crunches, or a brisk walk. It will clear your mind and balance your mood.

Quality sleep is extremely important. Try to get 8 hours if you can, and stop caffeine intake after 2pm.
