I've been following "The Math Diet" as described here:

If you're an electrical engineer like yours truly, you'll appreciate the control-theory aspect of it. I've lost 15 pounds so far.
Even if you don't understand (or want to understand) control theory, it's still pretty simple. You're not counting carbs or calories. But you are weighing yourself and your food. So this ends up being a form of "portion control" in the end, except the portions are variable.
It starts with the idea that you can't gain any more weight than the weight of the food you put in your body.
1. Decide how much weight you want to lose per week. Divide that by 7 to get your daily weight loss. As most people know, for long term, maintainable weight loss, it's not recommended to target too much weight loss per week.
2. Start the process. Weigh yourself in the morning. Helps to have a set of scales with at least 0.1 lb granularity. Take the difference between your goal weight for the day and your morning weight. That will be the amount of food you are budgeted to eat for the day. I allot the weight to be 25% breakfast, 25% lunch, 50% evening meal.
3. Then eat your calculated amount for breakfast and lunch. Make sure you have a good food scale for this.
4. Just before your evening meal, weigh yourself. Take the difference between your target weight and your current weight. That is the weight of the food you actually get to eat for your evening meal. It should be more than what you originally budgeted because your metabolism has been running all day. This is where, in control theory "the loop is closed".
TIPs
- How to put this delicately... Be consistent with regards to when you weigh yourself and when certain bodily functions tend to occur for you.
- Also be consistent with regards to when you weigh yourself relative to when you drink liquids. For the evening weigh-in, I usually wait at least an hour since I had my last glass of water, for example.
- Also be consistent with regards to weigh-ins and exercise. I exercise late afternoon (cycling), so I do my evening weigh-in just before I go out and cycle to avoid any distortions due to losing water weight due to sweating. The calorie burn due to exercise will then show up as a lower weight the next morning anyway.
- OK, we're basically using weight as a (poor) proxy for calories and/or carbs. I've found that when the food I eat over the course of the day is lower carb and unprocessed, I get to eat quite a bit for the evening meal. Go figure.
Anyway, I find this to be pretty easy and over time I'm already getting a pretty good feel for how much I need to eat. Even if it didn't, I could still use this for overall long term weight management.
One of the main advantages I see for this is that I lose *exactly* the amount of weight per week that I want to, no more, no less.
Your mileage, of course, may vary.
