Well one thing that no one has to worry about is "getting huge". It just wont happen without years and years of working out. You should currently be worried about cutting down and losing the weight. To do so you need to first start with your diet. When cutting down you want approx 10-13kcals per pound of bodyweight (compared to bulking up with 15-18kcals). So with your bodyweight, since I'm sure you want the fastest result, will need about 1780kcals per day to loose weight.
Now,
1 gram of protien is 4kcals
1 gram of carbohydrate is 4kcals
1 gram of fat is 9kcals
Now the ratio that almost everyone uses wheter it's bulking or cutting is the 40/40/20 method. Meaning, 40% of daily kcal from protien, 40% from carbs, and 20% from fat.
So for you,
40% of 1780=712 kcals Protein
40% of 1780=712 kcals Carbs
20% of 1780=356 kcals Fat
So in grams you will need,
712 / 4 = 178g Protein
712 / 4 = 178g Carbs
356 / 9 = 40g Fat
PER DAY^^
So at 5 meals a day, you're looking at,
35g Protein per meal
35g Carbs per meal
8g Fat per meal
So now that you have your eating down. Your training should mainly consist of cardio if getting the weight down asap is your goal. Running or walking should be performed at a minimum of 30min (cardio), your body doesn't burn fat until around that time period. You can lift weights, but if your goal is loosing weight, do them high reps with lower weight. Theres no point in lifting big at this stage if you have fat covering your muscles. Aim at around 20 reps per set x 3-4 sets on everything, and do them quick like cardio (your heart should be pumping after every set and you breathing hard). Aim to doing this 5 days a week, targeting specific muscle groups every day after your cardio jog for 30min+.
Day 1- Triceps
Day 2- Bicep
Day 3- Rest
Day 4- Chest
Day 5- Back
Day 6- Shoulder
Day 7- Rest
These are sure fire ways to get that weight down as soon as you can, but without following what I said you will not loose the weight, you need to stay committed to the regime everyday. Any questions feel free to ask.
