I've lost 20lbs in the last 10 weeks by combing intense cardiovascular work with Ori Hofmekler's Warrior Diet. The diet calls for under eating (and exercise) during the day, and overeating at night. So instead of eating the usually recommended smaller more frequent meals, you eat 1 big meal at night.
I know it is against everything we think we know about energy and metabolism and good dietary habits, but there are more things at work here than just burning calories. Hofmekler, a historian who studies ancient warrior culture, explains how our ancestors ate this way. Although for them it was mostly out of necessity, he gives sound reasons suggesting how modern man could benefit from periods of not eating. It's an interesting book and I appreciate the historians perspective on diet, it makes much more sense to me than pseudo-science.
Anyway, if the thought of not eating breakfast, lunch or anything else throughout the day, only to eat one big meal at night is not something you'd think would be healthy or good for performing your best, let me tell you how I have lost body fat and gained strength and endurance!
As for my lifting, it has been primarily kettlebells for the last couple of months and I have been using the GS/kettlebell sport ranking charts as my barometer. What that means is I'm focused on long duration high rep sets. I jerked a 24kg bell 170 times today with no put downs and only one hand switch (80r/90l). My previous best was 75/75 (and that was done 20lbs ago, before starting the Warrior Diet). Today's record was done on an empty stomach and after a 3 mile run on my lunch break. I've been keeping up with a few basic calisthenic exercises like push-ups and pull ups, but I average about 5 miles and 500 kettlebells swings a week; along with my primary focus of jerks, snatches and long cycle c&j.
The only heavy lifting I've done in the last month or so has been a 500lb farmer’s walk for a few runs. I have lost some limit strength with the drop in bodyweight but it pales in comparison to the gains I've experienced in other areas. As for my activity level, I feel like I have more energy when I am not bogged down by a heavy breakfast and lunch. I've been extremely productive with mid-day workouts, teaching classes, home projects, household chores and creative tasks at work and on the web.
I've lost 20lbs eating like this (down to a svelte 225 :) but more importantly, I feel better throughout the day. I'm questioning whether eating breakfast actually "boosts the metabolism" as we so commonly think. My energy levels are higher and I feel more alert going through my day with little to nothing to eat. Was this really how "warriors" or ancient civilizations ate? It doesn't matter. I've found a diet that not only keeps me lean but makes me feel good too! Is it healthy to eat this way? When was the last time you ate that many vegetables in a day?
