My goal is basically to build a diet plan that anyone can use and tailor to their own purposes.
Too generic. For example, a bodybuilding diet plan is different from an endurance cyclist diet plan. Michael Phelps (Olympic swimmer)
ate 12,000 calories a day due to the caloric intake his workout and metabolism required. This is why you need a specific goal - to tailer the diet plan to your own purpose.
The max recommended healthy weight loss I've read is 2 pounds a week (although the first 10+ pounds usually go off quickly due to water weight or whatever, and the last 20 are usually harder to lose). Otherwise you risk
loose skin (this happened to a buddy of mine after losing 150 pounds in less than a year - not this pic though, that's just a random google one). So if you want to lose 30 pounds, 30 pounds divided by 2 pounds a week equals 15 weeks, which is only about 4 months.
The key is diet. The fat loss sticky pretty much explains it all. Just be warned of emotional marketing (ooh, chocolate protein bars! lol) vs. eating whole foods. A cookies & cream protein shake may look like a pretty good way to bulk up and lose weight, but check out the ingredients and sugar content inside.
The best fat-loss diet I've had is eating 5-6 small meals a day, made up of lean protein, good carbs, and good fats. I like this method because it keeps you full during the day, which helps you to not eat junk food - you still get cravings, but it's a lot easier to deal with because you are full all the time. I lost 50 pounds doing this - along with 10 or 15 minutes of cardio a day. Really easy - eat food and do just a bit of cardio every day. My old
14-day meal plan is available if you want a copy. My
current meal plan is a little different (9 meals a day, and no wheat - I found out I'm gluten-intolerant and also I have a high metabolism).
The real key to making this happen is to have a plan that has been proven to work and to follow that plan. My current plan is basically eating the same 9 meals every day (there's enough rotation in there that I don't get bored of the foods), cooking all of the meals in the morning, and carrying my giant lunchbox with me so that my food is always available within arm's reach. This makes it so convenient that I actually do it, lol. If I don't have a meal plan, then I have nothing to follow to cook. If I don't go shopping, then I have nothing available to cook. If I don't cook in the morning, I get busy and forget and don't follow my diet.
And there are a lot of ways to do it. The Michael Phelps diet might work for you. I have a friend has follows the "Eat whatever I want and workout for 2 hours a day diet" and she is skinny because she eats junk food all day, but burns it all off on a daily basis (maybe not the healthiest method, lol). Look at the runners you know - they typically eat a ton of food, but burn it all off through their long cardio routines. Some people eat one big meal a day and are successful bodybuilders. There are lots of paths to get to where you want to go...the trick is to identify what your goals are, specifically, and then to tailor a diet & exercise plan around that.
