Sharing his weight loss journey to Reddit, user tivons76 posted before and after transformation pictures. He did not say how much he weighed at the start and end of the one year journey – but the pictures spoke for themselves.
Other Reddit users were quick to jump in the comments to find out how he did it.
And there is one popular diet plan he followed to slim down – the keto diet.
He also used intermittent fasting to slim, particularly around his waist.
The dieter wrote: “The last 4-5 months I’ve done 16-8 IF. It’s helped a lot with the plateaus. I’ve been doing that plus weight training lately and have had great results.

What is the keto diet?
The keto diet, or ketogenic diet, is a low-carb diet plan.
Dieters may only eat low carb foods, such as lean meat and dairy. The idea of the diet is to put the body into a state of ketosis.
This is an alternative metabolic rate in which the body burns fat instead of carbohydrates to survive.
What should you eat on the keto diet?
The macros for the keto diet are typically 60 to 75 per cent fat, 15 to 30 per cent protein and five to 10 per cent carbs.
Meals should be based on meat, fatty fish, eggs, butter & cream, cheese, healthy oils, and low-carb vegetables.
Alcohol is not encouraged, as it can throw a dieter out of ketosis.

How can you tell if you are in ketosis?
Suzannah Robin, who is behind a new device to test whether someone is in ketosis, revealed how to tell if you are in ketosis.
How can you tell without using a device? She said: “There are a variety of ways to tell whether your body is in ketosis. Some methods are more reliable than others as they depend on physical signals that aren’t always consistent and could be indicative of something else, such as bad breath.
“The most obvious signal, of course, is weight loss. Appetite suppression and increased focus and energy will also tell you if the keto diet is working for you. However, these signs alone won’t tell you exactly when you are burning body fat and, if so, at what rate.
“Knowing this will help you to optimise the keto diet and your exercise regime, and tailor them accordingly.”
However, there are more accurate tests you can use. She added: “There are three methods of testing for ketosis – blood, urine and breath.
“In the last few years some breathalyser manufacturers have tried to adapt electronic breathalyser semi-conductor sensors to detect the acetone that is produced during ketosis. However, these devices, while relatively cheap, are generally inconsistent, are inaccurate at lower levels and can’t be calibrated, so have a fairly short lifespan.”
The Ketoscan Mini is the world’s first portable cartridge-based analyser, which can tell if you are in ketosis using your breath.
