Sam Feltham carried out an experiment a few months ago that caught a lot of attention. For three weeks he pigged out on low-carb LCHF foods, 5,800 calories a day.
According to simplistic calorie counting, Feltham should have gained 16 lbs (7.3 kg). But in reality, he only gained less than 3 lbs (1.3 kg).
Now Feltham has repeated his experiment with exactly the same amount of calories, but from carbohydrate-rich junk food. On the same amount of calories he gained more than five times as much weight: almost 16 lbs (7.1 kg)!
The difference in waist circumference was even more significant: 5,800 calories of LCHF food for three weeks reduced his waist measurement by 1 1/4 inches (3 cm). The same amount of junk food led to a 3 1/2 inch (9.25 cm) increase in his waist. And you can see the difference visually.
A picture is worth a thousand words
Above are photos from the junk food experiment. Below, the LCHF experiment (with the same amount of calories) as a comparison:
A calorie is not a calorie. This has already been proven in study after study, but Feltham provides us with a nice real world illustration.
Here’s his final report: Day 21 Of The 21 Day 5,000 Calorie CARB Challenge
What do you think about the outcome?
