I am 18 and my weight is 190 one week and 175 the next, and it never looks like I gain or lose. So for the that reason I dont like to say "I want to lose 10lbs". What I want is a more trim body. I dont want to be cut or anyting like that, I would just like a flatter chest and back.

I would like to know what NOT to eat, because I still live with my parents I cant diet very well since I tend to eat what they eat.

Also, since I am currently going to college and have a part time job I dont have time or money for the gym. I do have a punching bag though. I am somewhat active aswell.

What I would want for exercise are what I can do to just slim down. Like how long should I walk/run for a week/day? How many push-ups? Just a basic thing to keep me active and maybe over the next month lose 10 lbs and get a stable weight.

here is john berardi's 7 habits for nutrition. if dont' want to worry about macros, whether or not you can eat this, will this cause an insulin spike, is it high GI etc, then you can use these rules to make your life much simpler

when i first started out, i followed what he wrote without counting calories and worrying about macro % and made a lot of progress. the only one i did not follow was the one about a no calorie drink because i drink lots of milk

anyways, i didn't write this, it's from john berardi

The 7 Habits of Highly Effective Nutritional Programs
Here’s my take on it. I call these principles, "The 7 Habits of Highly Effective Nutritional Programs," a shameless and possibly illegal play on Steven Covey’s book, "The 7 Habits of Highly Effective People." (Great book, by the way—you should read it sometime.)
These aren’t the newest techniques from the latest cutting-edge plan. Rather, they are simple, time-tested, no nonsense habits that you need to get into when designing a good eating program.
1. Eat every 2-3 hours, no matter what. You should eat between 5-8 meals per day.
2. Eat complete (containing all the essential amino acids), lean protein with each meal.
3. Eat fruits and/or vegetables with each food meal.
4. Ensure that your carbohydrate intake comes from fruits and vegetables. Exception: workout and post-workout drinks and meals.
5. Ensure that 25-35% of your energy intake comes from fat, with your fat intake split equally between saturates (e.g. animal fat), monounsaturates (e.g., olive oil), and polyunsaturates (e.g. flax oil, salmon oil).
6. Drink only non-calorie containing beverages, the best choices being water and green tea.
7. Eat mostly whole foods (except workout and post-workout drinks).
So what about calories, or macronutrient ratios, or any number of other things that I’ve covered in other articles? The short answer is that if you aren’t already practicing the above-mentioned habits, and by practicing them I mean putting them to use over 90% of the time (i.e., no more than 4 meals out of an average 42 meals per week violate any of those rules), everything else is pretty pointless.
Moreover, many people can achieve the health and the body composition they desire using the 7 habits alone. No kidding! In fact, with some of my clients I spend the first few months just supervising their adherence to these 7 rules—an effective but costly way to learn them.

Just curious about something that may be a "typo".

You stated you weigh 190 one week, then 175 the next. Did you mean 180 and then 175? If not, just curious as to how you keep going back/forth by 15 lbs. every week? Are you 190, then out of no-where you are 175?

I know I fluctuate by 5-7 lbs. over the course of the day (on some days only) depending upon water/salt/glycogen/any water retention from the water/salt, etc., but not 15 lbs. back/forth as a constant event. Just thought it may be a typo and was just curious that's all.

Thx,

~SC~No, it wasnt a typo. Some days I lose or gain 5lbs.

I am almost sure that it has to do with this. Some days I weigh myself after workouts and I weigh more. Other days I dont work out and I weigh less. Some weeks I dont work out at all (active, but dont work out) and I weigh about 180 something.

I consider my normal weight to be 160-170 depending on muscle mass.

All I want is a very basic daily workout routine, and I know I'll lose alot. I need a workout for my back tough...
