Looking for some advice and opinions. I'm trying to lose weight and tone up a bit. I am 224 pounds, but only need to lose about 25 or so to get where i want to be. I lift weights four days a week for about an hour. I use a "medium-heavy" weight for me. I am only taking in 1,700 to 1,800 calories a day, with about 70 to 100 grams of protein. My worry is that this is too little energy for me. I don't feel weak or deprived of food, but i don't want to break down my muscle. I have been told by folks that with adequate protein i will be just fine, but i have also been told that i'm taking in too little. And as for now i am not introducing cardio into my plan. I do understand that cardio is important, and would increase my calorie intake if i were to start cardio. Any thoughts? Thanks.
