You'll have to turn your fat into muscle to get toned, that's what toned is. But you don't need huge defined muscles if that's what you're wondering, and you won't get huge defined muscles without protein powder and carb bars etc so don't worry about that.
Are you asking this because (this might sound mean) you're too lazy to want to lose weight or do exercises that are required to burn fat and make muscle?... or are you asking because you are a thin person and want to get toned without losing weight?
Either way, if you eat right and exercise right you'll be able to keep track of your weight and although you won't stay at the same weight on the scales (muscle weighs more than fat) you'll look the same weight, just more toned and defined.
If you haven't got much fat on your body that's actually a good start because many people lift weights relentlessly only to complain that it's not doing anything to their muscles... because they have a layer of fat over the top... when they lose that fat then you'll be able to see their muscles! So being a thin person to start with is a good start, you'll notice the difference sooner. You'll want to buy weights or go to the gym, work on all parts of your body because you want to make your gain even. Eat protein and lots of veges and drink lots of water!
I want to address some things as I answer this question for other readers, if I may. Getting leaner doesn't come without some form of weight loss, as the whole point of "toning" is to lose water weight/adipose tissue/mitochondria levels to expose deeper striations in the body.
It's not humanly possible to convert muscle tissue into fat or vice versa. Fat is made up of adipocytes which are fat cells that come from cytoplasm and loose connective tissues. Muscles are made from myocytes, which are bound by myofibrils or connective tissue that is tight. To convert one into the other is impossible.
If you're worried about getting "huge", stop because it won't happen. A female's testosterone production and conversion is less than 10% compared to a male. The chances of you getting "huge" is literally thinner than a pencil because unless you're on Test E or Test P, you won't get "huge".
As you lose weight (preferably body fat), you'll expose the striations and muscles so they appear bigger, but they're not. During leaning out though, you might experience some hardening effects which means your muscles will look a bit more vascular possibly due to lower fat levels and higher temperature making the veins rise to the surface to cool off.
To answer your question in a simple word - No.
To answer this question as a response to the way you meant to word it, yes. you can always do simple exercises like crunches or squats depending on where you want to get toned. Doing simple but muscle-strenuous movements like this won't burn enough calories for you to lose much or any weight, but fat will be replaced with muscle during the process, and once you get to the right shape, you will start to become noticeably toned in your targeted area(s).
You can add muscle without losing fat if you eat a good amount of protein and carbohydrates, combined with resistance training. If you're not wanting to lose weight, you need to make sure you are eating enough calories to account for the energy expenditure.
^Exactly that. If your muscles aren't 'toned', it generally means that there's a layer of fat covering the muscles. Your muscles could be as big or as strong as anyone's but if you can't see them, they aren't 'toned'.
sorry i worded it wrong, i know toning requires muscle but i meant to say massive muscle lol i did not proof read
No, getting toned means turning your fat into muscle.
