KoolDrew's answer is dead on and to the point, but some explanation may be useful: doing high rep, low weight (or bodyweight) exercises will NOT make your muscles look any more "toned". You could do 100 push-ups per day and your muscle "tone" will not change in any noticeable way. You will build muscular endurance and it's still a healthy thing to do, but your overall appearance will not change.
You get "cut", "ripped" or "toned" not by doing anything to your muscles, but by losing fat. Let me repeat that: to get "toned", the only thing that matters is lowering body fat percentage. This is done through a good diet with a moderate calorie deficit. Unfortunately, from diet alone, your body will burn not only fat, but also muscle. This is not only unhealthy, but even though you'll lose weight, you'll still look flabby, as your body fat percentage (due to the loss in lean body mass) would still be too high. To counteract the muscle loss, you need to keep protein intake high (~1g per pound of bodyweight) and you need to lift heavy. No, you won't suddenly bulk up from lifting heavy, especially on a calorie deficit.
Edit: as a side note, once the fat clears, you will look better if you have a solid base of muscle underneath. If you don't already have that, lifting heavy is the way to do it.
