| First off, congrats on your weight loss so far! It's not an easy thing so good for you with sticking with it. I am sure your children are one of the main motivators to getting yourself back in shape.
Now as for your plans. They are right where they should be, but remember your diet plan is your biggest challenge and the most important factor in loosing weight. You want to make sure you are eating whole foods, proteins, fats (yes sounds silly right?) and carbs. You should be incorporating proteins into all your meals and should be eating complex carbs (long grain rice) and proper fruits and veggies.
If you feel ok with a caloric deficit of 1000 cals then go for it. If you are feeling weak and not yourself one day then eat a little more. I personally cannot handle a 1000 calorie drop in my daily intake but 500 seemed to work just fine.
Make sure you do a full body workout. You don't need to kill your legs, but the simple act of lifting helps boost your metabolism as you body repairs the muscles..i.e. you burn more calories--->lose more weight.
Use cardio as an add-on for helping along your caloric deficit. It shouldn't be your main focus but a combination of weights and cardio as you have been doing is the best.
Most importantly keep at it! Keep a journal on here with your daily food intake, your exercise plans and anything else you want to talk about. Its much easier when people are behind you to keep going through a tough time. It's easy to slack if no one knows what you're working towards.
Good luck!  |
