I lost 8 kg in 2 weeks.

Is that healthy? I read somewhere losing more than 2kg a week is not healthy.

I am 30 years old, 1.68 meter and was 83kg, today i'm 75 kg. My target is to be around 53kg-60kg. I started diet and exercise 2 weeks ago. I also work sedentary job (9.5 hours of sitting).

I yet measure my current body fat by I also aim to be around 10%-15%.

My routine is very simple, all this 3x times a day: morning before work, during office hour, and 1-2 hours before sleeping

- jogging for 20 minutes at least
- 100 meters dashes (4-5 times)
- going up the stairs (slowly) from G to 12th floor.
- push up on rails or walls (newbie push up) 10 reps 5-7 sets
- jumping jacks 10 reps 5-7 sets
- Squats 10 reps 5-7 sets

My diet is also simple, I eat 1 or 2 fistful of rice (lunch or dinner or both) everyday with 1-3 fried egg (w/o oil). YES that is all I eat, I hate veggies and I surprisingly rarely starve during those 2 weeks.

Water intake is 2-2.5 liter a day (aiming for 3 liter a day but I couldn't do it LOL)

This week I will start hitting the gym 3 days a week (Tues, Wednes, Fri) to eliminate moobs and do curls. Also will start jumping rope challenge soon and hopefully HIIT workouts. I also plans to take vitamin capsules since I don't and won't eat veggies and fruit.

I will also start drink coffee, never had them in my lifetime, I heard coffee is good to suppress hunger <- please advise.

Also it means 2 weeks of:
- no sugary drinks/foods
- no oily, fried, deep fried foods
- very small amount of snacking during office hour (just some beans, sunflower seeds and similar)

Am I on the right path? My plans is a damn mess I know, that's why I need advice and suggestions.

My primary aim is to lose weight, and then body fat, and then maybe, just MAYBE bulking up muscle. I'm unsure if I want to be one of those huge guys.

Quick background:
I was very active years ago, weighing around 54-60kg, then got sedentary job, becomes 83kg after 4 years.

Does this mean I-gain-weight-easily-and-lose-weight-easily-too type of guy?
