Lifesize, The Company

The Lifesize company was created to
re-teach people how to eat so that they could lose weight, get down to a healthy weight, and most importantly, stay at their healthy weight for the rest of their lives.

We developed the simplest way for people to track the calories they eat in a meal and in a day, because we believe that if something is simple, people might actually do it.

We designed portion sizes of food that are based on calories and over thirty years of studying what and how much people need to eat to be satisfied and also stay at a healthy weight. And we created tools to help people see and understand what their meal plate and what a total day of eating should look like.

The two inventors of the Lifesize tools and the Lifesize Program are Steven Kates and Myles Berkowitz.

About the Lifesize Founders

Steven Kates has been in the fitness and nutrition business for more than 30 years.

Steven is known in Los Angeles for his work with celebrities, his ultra-modern fitness operations, and his scientific training techniques. He was Executive Director and Chief Operating Officer of the first Nautilus Chain in the West, and introduced Nautilus to Los Angeles. Spinning was invented in one of Steven’s Nautilus complexes by his friend and employee Johnny G.

Steven has founded and operated several fitness studios and workout facilities in the Los Angeles area, including Matrix 1 Fitness complex – the birthplace of the private training industry.

Steven has a Bachelor’s Degree in Biology from UCLA.

Myles Berkowitz is a filmmaker in Los Angeles. He’s been in the entertainment business for over 20 years, and most notably wrote, directed and starred in the Fox Searchlight film 20 Dates.

Myles Berkowitz knew nothing about food and dieting when he met Steven four years ago.

Myles didn’t know that rice was a carb! When Steven started talking to him about the proper portions of food he should eat, Myles made him draw those portion sizes on a piece of paper. Myles then made clay bowls from those drawings and used them to portion out his food. He immediately felt much more energetic and the weight started to melt off.

Myles was convinced that portion control was the answer to the obesity problem in America, but couldn’t find one place to get all the information a person needed to portion food properly.

So Myles and Steven decided to fill that knowledge gap. Together they came up with simple-to-use measuring devices and a complete Lifesize Program that even a dummy like Myles could understand.

Myles has lost 46 pounds on the Lifesize Program. But the bigger news is that he’s kept that weight off for over 3 years while still eating familiar and favorite foods, but in Lifesize portions.

Elisabeth Berkowitz, married to Myles, also has much to say about Lifesize.

Her easy-to-follow and practical instruction on the Lifesize Ready. Get Set. Go! DVD will help get you up and running in no time. Elisabeth is an interior decorator and has a degree in design from UCLA. After giving birth to a daughter, Elisabeth lost 21 pounds on Lifesize and has kept that weight off for over 3 years.
