Getting to these 8 km is a rough journey for someone who is overweight and their food intake is the first reason for their problems. Lack of sport is rather the effect.
It is like saying that simply building the CERN accelerator will give you a PhD.
Also, running (rather, jogging) isn’t terrible aerobically taxing, if you can’t keep up a convo, you’re running too hard.
Once you’re used to running, it’s an insanely efficient way to create a calorie deficit. Not the most glamorous exercise, but cheap, easy, requires no significant equipment and most all, incredibly time efficient.
1 kg worth of body fat is about 7700 kcal or 7.7 kcal per gram. One m&m is about 3 kcal, if you run 35 meters for each m&m you can eat the whole bag :) You don't have to eat the whole bag.
If you gradually build up to 8 km/day it isn't very likely to kill you. 1000 dollar/month however... If 110 km in two weeks takes more than 2 hours/day you aren't really jogging. 28 hours in two weeks is $35.72 per hour.
