If you do not have the time to eat due to your job, then consuming protein bars, yogurt smoothies or a high calorie drink (milkshake) would help you during the middle of the day to get the calories you need to maintain your weight. Thank you for your question.
yo i get you. I know how those companies work. i do landscaping too. What i do is pack my packpack with lots food. sometimes i take whole wheat peanut butter sandwich, or ham sandwich, almonds, apples, protein shake, oatmeal bars. or foods with high fiber. I take protein bars too but they can be expensive throughout time, so i made my own. My backpack gets full of food man lol, but try to go for the snacks or foods with complex carbohydrates no sweets or junk food
