I used to be about the same as you, shorter than you, but now I'm over 90, 120 kg. All through long-term efforts. Really tired, sometimes physically and mentally exhausted. ..
What I have done in the past. ....
I think you'd better sweat when you exercise, and don't collapse alone after exercise, which will make you feel that all your efforts are in vain.
I suggest you get up early in the morning, say 7 o'clock, and then go for a run outdoors. Aerobic exercise is more conducive to burning fat. You can stop running for 40 minutes, but don't stop too many times.
Then after an hour and a half, take a break and have breakfast. Don't eat too much, just one egg and a box of milk. I'm sure it's a diet breakfast.
You can have a rest in the morning, but don't sit for a long time. You can take a walk at eleven or twelve o'clock and drink a glass of water before lunch to reduce your appetite.
It's best not to sit and walk around for an hour after a meal. If you take a nap, you can sleep for an hour, and it is ok to sleep for an hour. It's not too hard to exercise at five or six in the afternoon, such as yoga. Yoga is a relatively gentle exercise. After cooking for forty or fifty minutes, you can eat at six or seven, but the meal is not for you.
After 8 o'clock, you are on an empty stomach. What you eat after 8 o'clock is equal to being fat. You can eat if you want. ....
You can do some exercise before going to bed, such as skipping rope, and it will take half an hour. Then go to bed, remember to go to bed early and get up early, and you must get enough sleep to lose weight!
The above is my experience!
