Do note that any kind of physical activity will enhance your need for nutrition. But you need to be careful here. This does not mean that you start eating anything you can lay your hands upon. You need to make careful diet changes here.
Increase Your Calorie Intake
Since you are exercising, you are burning more calories. Hence you need to eat more. But in case you are cycling in order to lose weight, then you must restrict the number of calories that you consume. Do note that any kind of physical exertion will make you hungrier. But you need to ensure that you check with your dietician about nutritious food to eat when cycling. In case you are eating more than what you are burning, then you would not be able to lose any weight. Also, the number of calories to consume will depend on the amount of cycling you do. This would mean the distance traveled, the time to cover that distance as well as the terrain. All this will indicate the actual exertion your body has gone through and the way you need to replenish any nutritional deficits.
Before The Cycling
In case you are cycling the next day, do not stuff yourself with a lot of food stuff the night before or just before going out for your exercise routine. Rather than giving you energy, it will only add to your digestion woes. Do note that the stomach takes around 2 hours to digest food. Hence if you are cycling on a heavy stomach, you may be having aches on the way. Besides, too much of heavy food will simply make you lethargic and tired through the way.
You need to stock up on proteins. These will give you a boost of energy to last you through your cycling ride. Hence you can consume sprouts, tofu and dairy before going out cycling. You may have lean meat such as fish and seafood, beans and pulses too. These are more filling than carbohydrates. In case you are going out on a long cycling trip, you may even carry high-energy energy protein bars with you. These will provide you with immediate energy when you need it the most.
Your diet should include a lot of fresh fruits, vegetables & fresh fish besides drinking lots of water. This is because you will be sweating more and losing vital nutrients.
