Space Case

I'm looking to lose 70 pounds and I've been doing weight training for a while now. My weight tends to go up and down a lot so I've just been maintaining. To maximize weight lose, would it be better to do strength training, or muscle mass building? This really confuses me because of differing information I keep encountering. Some sources say strength training is high weights and low reps, while others say it's high weights and low reps for hypertrophy. Which is it?? I'm so confused! I uploaded the routine I'm doing, and apparently it's for hypertrophy. I have noticed I'm becoming stronger, but that's it.

Hello all! I'm relatively new to the world of fitness and healthy diets. I just started weight lifting and learning about healthy nutrition needs. After hours of researching into a good diet for my needs, I ended up confused. I'm a numbers and research type person, so you can imagine my frustration when I read different sources with different recommendations of what good nutrient intake levels should be. It's just, ugh!! I know that everyone's body is different, so nutrition needs will vary. I just don't know what exactly will be best for me! I'm currently 5'8" and 156 lbs, and my goal is to slim down, tone up, and gain strength. I put on muscle easily so hopefully I don't turn into a she-hulk So how much should my daily protein, carbs, calories, and fat intake levels be? Thanks for any help!
