1) Cut on your carbs
This is one that definitely works, reducing your carbs intake will have you loosing burning fat and gaining muscle at a much quicker rate.
2) Eat more protein
A lot more calories per gram are burned in digestion when you consume protein. Compared to carbs at 6%-8%, around 25%-30% of calories are burned in digestion when you eat protein.
3) Drink plenty of water before a meal
Drinking a glass of water before having a meal will reduce your apetite and make you feel more full thus reducing your calorie intake.
4) Set records and push yourself
Try setting your own records and pushing yourself to break them every time. For example trying to run your normal distance on the treadmill in a shorter period of time than the day before.
5) Don't miss out on meals
Keeping your body without nutrition will put it in a catabolic state which means it will start using up muscle tissue to gain energy. You definitely do not want that!
6) Substitute sodas for 0 calorie drinks
Water is perfect at keeping you hydrated and won't have you putting on pounds of fat as it has precisely 0 calories
7) Watch motivational material
Every once in a while everyone needs an extra boost or motivation. Find something that motivates you be it movies or workout videos on YouTube.
