3. Protein powder and bars
Busy people are advised to take protein supplements in case they do not have any other option. Not only do you need a substantial meal consisting of all essential micro- and micronutrient, you also need sufficient amount of money to buy meat and fish. Protein bars as well as powder can save your money and time.
4. Water cannot be replaced
Carry a bottle of plain water whenever you go. Have a sip now and then even if you do not feel thirsty. Thirst indicates that your body is in danger. Remember that no other beverage can replace water. You need to hydrate your system. Sodas and juices contain too much sugar and lots of calories.
