Your profile says you're 6'1" and 175 pounds. Is that accurate, and if so, would you like to rephrase the last part of your statement? What did you weigh before you started training (like, 5 or 6 weeks ago)?
What does "a lot of training" mean? What exactly were you doing for the last month - what days were you lifting, what did you do each session (sets and reps, not weight), what did your cardio look like?
Also, you're 16 years old, correct?
The unofficial term for this is "skinny-fat." Not obese or heavy, but not muscular or defined. Let's say you spend the next month or three trying to lose fat, and you drop down 20 pounds. At your height, you now look anorexic. As the saying goes, 6-pack abs on a skinny guy are like huge boobs on a fat chick. They're not impressive.
What is your specific mid to long-term goal? Is there an ideal physique (athlete or celebrity) that you'd want to shoot for?
What, exactly, did you eat yesterday?
"Strenuous endurance exercise" sounds an awful lot like low intensity, long duration cardio like biking for dozens of miles or running for an hour or more. That's an very inefficient way to burn fat and almost a good way to burn muscle, so we don't want to train like that.
I think you should attack fat loss from the other angle, by increasing your lean muscle mass through smart training, a decent nutrition plan, and possibly a little hard cardio to keep things in line.
Nope. As was said, fats are super-beneficial. If anything, reduce carbs. But for even better progress, use this as a guideline to arrange your nutrition:
As a rule of thumb though, the more you cook for yourself, the better. I'm not saying to avoid family dinner and make your own stuff every meal of everyday, even just knowing how to do scrambled or hard-boiled eggs is a help. But don't leave the kitchen a mess. Seriously.
Cardio is preferably done right after lifting or on a separate day. Doing any serious cardio training beforehand will negatively impact your lifting session, which means you won't be in an ideal position to build lean muscle, which means you're not going to have a solid, strong, toned build to show off once you drop the fat.
I most certainly will not keep that in mind. Not only are you probably not an ectomorph, but the terms don't actually mean much in the real world. You're dahmer, a tall, skinny, unmuscley dude who, I figure, wants to get a little more muscley and be lean enough to show it off. Period, end of sentence.
If there's only one thing you buy, make it a workout shake like Surge Recovery.
Sorry if I threw a hundred questions back at'cha, but the more info we have, the better advice we can give.
