Yes but without exercise your muscles and your organs are not getting used efficiently and your body is going into starvation mode. these fad diets only last so long and then they will have a counter-effect.
If you lose too much weight too quickly, you'll be left with a lot of loose skin which will look even worse and is harder to tone up.
You need to have an equal balance of diet, exercise AND rest.
You don't have to be a bodybuilder to lift weights at the gym, at the end of the day it will only make you stronger and healthier overall. Same with cardio - you don't have to be a long distance runner, but it will keep your heart running better. Just like your zed's engine
Agree with all of that, but in a perfect world.
In my life at least, i'm 'too busy' to dedicate lots of time to exercise, and i'm also very limited in what i can do due to a permanent spinal injury. I also know that i like my bad foods too much, so i could never stick to a healthy diet.
So from where i'm sat, on Keto i get the best of both worlds.
