Mother Nature Network last January reported Alec Baldwin’s successful weight loss effort. An excerpt:
“I gave up sugar,” he told Access Hollywood. “I lost 30 pounds in four months. It’s amazing.”
“(I do) Pilates, spin, not as much yoga as I’d like,” he added. “When we’re shooting (’30 Rock’) it’s tough…When we’re shooting and I can’t work out, I just have to eat less. So, I’m very conscious of that. But sugar was the real killer for me — that was the problem.”

Diabetic Mediterranean Diet 
On David Letterman, he said he also cut out rice, potatoes, bread and fruit because they turn into sugar.
How lucky some people are, it is enough for them to cut their sugar. It took me eliminating sugar, grains, severely limiting fruits and starches, practicing IF to loose the same 30 lb, and it took me almost 4 years. However, the therapeutic effect of LC diet outweighs the weight management because I became extremely resistant to all kinds of infections, don’t need asthma medications any more, have no symptoms of pre-menopause, and less of migraines.
