Due to a back injury i can do very little exercise at all. Therefore as of last summer i was 6'2" and 19.5st, with no ability to lose it through exercise.
I then stumbled across a diet called 'Keto', which is i guess similar to the atkins diet in that it is a no carb/no sugar diet. I read a lot about this and saw sooo many peoples progress pics and success stories, i thought id give it a try. I promptly lost over 2 stone in less than 2 months, whilst eating some awesome food!
Known affectionately as 'The Bacon Diet', Keto's principle is that you must eat a 60% Protein, 40% Fat diet - hence bacon is one of the healthiest foods you can eat! You're not allowed to have too many vegetables either as these can contain carbs (broccolli, parsnips etc).
The science behind the diet makes sense - your body can either use Sugar, or Fat as it's energy source. Sugar is metabolised very quickly, and only takes 4 calories of effort to metabolise 1 gram. The energy earned from this is then quickly used up, leaving you with sugary cravings all through the day - hence why people snack on junk food constantly.
Conversely if Fat is used as the body's sole energy source, this is a much cleaner fuel. It takes longer to metabolise and uses 9 calories of effort to metabolise 1 gram. As a result there are no blood sugar spikes which cause cravings, so you feel fuller for longer.
I took december off the keto diet so i could eat crap food for the holidays, and i put 1st back on, but i've been on Keto for a week and already i've lost most of that again. I love it.
Seriously, if you do 1 thing today, read some of the posts on the forum below. Look at peoples progress pictures, and look at some of the awesome food you get to eat (i have bacon and eggs every morning!
