Losing weight is not a year long plan, rather it shows the result in few weeks if you follow a right diet and accelerate the weight loss through exercises.
Reduce your calorie intake is the first thing you should work on if you want to lose 10 kg in one month. Because by reducing 500 calories a day you will lose 5 kg in one month, which means you can achieve half of your target by just reducing your food intake.
But reducing calories doesn’t mean that you should not fulfill your nutrients need, rather it mean switching from unhygienic fast food and drinks to healthy fruits, vegetables and fish.
Start exercising for one hour daily, if you have plenty of fat then you may reduce 10 kg through jogging within a month, and if you are fat but not excessive then you will lose 4-6 kg in a month. Thus you will achieve the target of losing 10 kg in one month only.
