Weight 140 kg.
Usually, with a lot of excess weight in the first couple of months, body weight goes away rapidly - up to 10 kg per month. But no one will tell you for sure, tk. everyone's body is different.
Be careful with cardio: better not to run , because running you will “kill” the joints and spine with this weight. You can walk a lot, walk at a fast pace, downhill, exercise on a stationary bike, orbit track . Start at a slow pace, eventually lose weight, be able to speed up and even run.
Cardio should be done daily , at least for a short time. Try to gradually increase its duration and complexity.
From the diet, exclude fast food, sauces and juices from the store, fried, flour, unnatural sweets.
Be sure to get enough sleep and try not to be nervous: cortisol (stress hormone) interferes with losing weight. Everything will work out. I wish you success!
It is difficult to say exactly how many kg you will lose weight, but be prepared that at first the weight will go away more rapidly and, perhaps, 7-10 kg will be able to lose, or even more. In this situation, the main thing is to reasonably approach, because the body will be under stress and it is not reasonable to immediately offer it a carbohydrate-free and force its psyche in the first place.
First of all, reduce portions, remove snacks between meals, that is, after breakfast do not eat until a full meal, nothing but water is allowed. But increase the amount of water greatly, at first it will seem that, on the contrary, you are bursting with water even more, but this will pass, especially if you previously drank a little. And yet, do not immediately enter great physical activity.
It is physiological for the human body to walk. Just take the norm of 10,000 -12,000 steps a day, walk for pleasure, strive to make walking your habit.
Oh yes, about the food. Divide it into blocks: fish, meat, poultry. Everything is possible, it is important in what form. Do not fry, but bake better. Remove all sauces from your diet. The first thing. Fall in love with the taste of simple food, it really is a thrill and you will understand it later. Any vegetables, just limit starchy ones (potatoes, pumpkin, carrots, corn, beets). More green vegetables, no limits. It is better to either remove cereals altogether, or stop at quinoa, buckwheat, chickpea barley. Eat dairy products, if you tolerate well. But not for the night.
The usual food intake should be protein in the form of cape, fish, seafood, poultry, cereals and a lot of vegetables in the form of salad with rast or olive oil are possible. Replace sweet with seasonal berries
