its okay if youre not losing any weight! when i first went on diet and exercise, i actually gained 3 kilograms. if you feel like you have more energy and that you are toning up, youre doing the right thing. not losing any weight is the plateau stage, i think everyone has experienced a point in their routine when they are not losing any weight even though theyre trying really hard. mine lasted for a very very long time (almost 3 months) (it really depends on person to person, some last only 2 weeks) . i know it can get very annoying, but after you pass that stage you will lose weight quite quickly. dont completely cut out on junk food, because if you do and lose a lot of weight, when you do start eating things like bread you will gain weight faster because your body is not used to the kind of carbs. dont cut it out, just limit the intake. and really! dont worry about the weight on the scale, just measure it by your fitness and how your body shapes up!
