calories and weight training

Hi! So this question may have been asked before, but I am just confused about weight training and cardio. I understand that weight loss is calories in versus calories out. I just started a weight lifting plan called, Livefit by Jamie Eason. I have two questions to follow:
1. Will I lose fat and gain muscle eating at a small deficit of 250 calories per day? I have about ten pounds to lose so I know my goal must be smaller...
2. If it is calories in versus calories out, should I just do cardio as I burn more calories doing this?

The help and insight is truly appreciated,

A person who is the same height and weighs much more can be much healthier. Muscle is denser than fat, so basing progress off of weight isn't always ideal (this is why BMI calculators are flawed- pretty much every pro athlete is considered "obese") I would suggest you go off of 1) body fat, 2) pictures 3) measurements.

You can technically burn more calories doing weight training than cardio. It all depends on volume and intensity. Ideally, you would do both.

I also want to add that when weight training, you may need to eat MORE to lose the same amount or more of weight. Weight training takes a lot of calories, and you can't maximize your lifts without proper caloric intake- therefor if you don't eat enough, you won't be able to life enough, and you won't progress as well. Also, the more muscle mass you have, the more calories your body requires to sustain itself (more muscle mass = more calories burned just by living)

Unless you are a newbie to weight lifting and have a fair chunk of fat to burn it is pretty much impossible to gain new muscle in a caloric deficit.

Bummer! I was hoping that I would be able to lose fat and gain muscle while eating under my maintenance. Is it worth it to lift weights when I just want to lose fat?

Yes. It will help ensure you lose fat, not muscle while you lose weight.

And you can still gain strength while in the deficit.

So are you saying if you have alot of weight to lose then you can eat less and gain muscle mass needed

Sorry my question was to you.

People have been observed to gain small amounts of muscle at a deficit, particularly if we're talking targeted spots of muscle vs. overall LBM increasing, but the general rule of thumb is that you're lifting to preserve the lean mass you already have and potentially gain strength when eating at a deficit. People debate this subject into the ground, but at the end of the day it simply doesn't matter. Whether you end up gaining muscle or not, you'll still see benefits from training hard and it's not worth your time worrying about whether you'll gain .5 pounds of muscle over many months or lose .5 pounds of muscle over many months. Just focus on training hard, getting sufficient protein, and let the cards fall where they may.

Most people who have been at it for a while are in the neighborhood of +500 cal for gaining mass and -500 for cutting. Any more and extra calories are unused and add fat, and any less and you lose your muscle gains. Yoyo dieting is bad. Just my .2 cents
