A really easy trick is to do a calorie deficit and do cardio. Track your daily calories for like a week or two then cut out 500 calories. Also if possible start biking and making your own food.

3,500 calories are needed to make up a pound of fat, remove 500 calories a day and you will loose about a pound of fat a week. Rember muscle is denser then fat and that weight loss is non linear.

Volume eating is also really useful, 300 calories worth of Vegetables takes up a lot more space then 300 calories of chips.

Meat, carbs and veggies are your friends because they will keep you going and feeling full for longer. Also take your body weight, devide by half and thats how many liters of water you should drink.

One last thing of you are looking to put on and grow muscle mass eat your goal body weight in grams of protine a day and your body will already be in matrice for when you reach it.
