No Results with INSANITY

For the diet portion did you weigh solid foods with a scale and measure liquids? If not there is a very good chance you were eating 10-30% more than you thought you did.

I think insanity results depend, like any program, where you start and what your goals are. I didn't see any measurement or weight differences, but I used it solely to train for a half marathon, only running one day a week and did well in my race. When you say 40/40/20 - that's 40 carb 40 fat 20 protein? I'm at a 35 carb, 35 protein, 30 fat and have finally been able to see the differences in my body fat percentages decreasing again. IMO, you really need more weight training to see measurement differences if you are already at or near a goal weight. I did P90X and had already lost weight - but ended up losing bunches of inches and clothing sizes from the strength training. Another thought - have you considered looking into kettlebell training?

Have you been mixing weight lifting / strength training into your workouts? INSANITY is largely a cardio workout, which will help get rid of fat to a point, but muscle takes a lot of energy to fuel. Building muscle will help you burn fat more easily and give you a "leaner" appearance.

It sounds like you followed the routines and diet plans properly. I honestly don't know why you wouldn't be losing the inches that you want to lose - so I don't have much to offer from a medical or physiological point of view. But, I can tell you that I see the most results in my Insanity and P90X workouts when I focus on keeping my core tight during workouts and maintaining focus and intensity throughout the workout. I have gone through both workouts with sweat dripping effort but without keeping my core tight and felt like I didn't even work out an hour after the workout. So for me, the key has been to focus on core tension.

I can also commiserate with you to an extent. I have gone through plateaus and maybe that is what this is for you. I lost about 30 lbs by getting into long distance running. It was really good for me and I felt great after every run. But after about 6 months of running and increasing my mileage and losing weight, my weight loss completely stopped even though I was running longer and farther than I ever had before. I then switched to P90X and lost another 20 lbs over those 90 days. I think the diet and exercise change triggered my metabolism (I finally found balance between aerobic and anaerobic exercises) and the weight fell off even more. By that point, I didn't have much more weight to lose but I still had (and still have) a bit of belly fat (skin?) that hides any sort of definition underneath.

The weight loss is now more gradual but I keep looking for ways to completely shake up my workouts so that I trigger more weight loss. I am constantly working at this. To give you an idea: I have gone through periods where I do 2 workouts a day for about an hour a piece, switching between P90X, Insanity, and distance running. I burned a lot more calories, had to consume a lot more calories to keep myself fueled, and lost a few more centimeters around my waist. From there, I added swimming into the mix and tailored my other workouts around swimming a few times a week. Now, I am focusing again on muscle mass and strength - cutting out carbs for a bit and focusing on proteins and fat (about a 40-20-40 p-c-f balance). My hope is the muscle confusion and diet shift will help me lose more belly fat and some of my core definition will start to show through. We will see.

Keep fighting the good fight. Get creative with your workouts and diet. Be sure to focus on your core and get enough calories to fuel the burning. Don't get discouraged - everyone goes through these plateaus as our bodies get accustomed to the workouts we do. KEEP UP THE HARD WORK!!

Calories in vs Calories out.
Maybe you didn't burn as man calories as they predicted, so your calories out was lower.

Wearing a HRM to work out calories out and using MFP for the calories in is probably worth it.

OP: how much do you weigh? I ask this as 1900 is quite high if you don't weigh a lot. the 1700 cal plan may be more suited to you than the 1900, as the estimated calories burned on that program are typically lower than what it says.
