calories. burn more than you take in.
This is only partly true. Mass. expel more mass than you take in. If you eat one pound of celery, your body will take the water and a little nutrients and you'll poop and pee nearly one pound of celery. If you eat a pound of sugar, your body will absorb almost all of it and you'll expel an ounce or so. That candy bar might have 1200 calories, but it only weighs 3oz. You can't gain a pound from eating 3 oz. You CAN gain a pound by eating a certain TYPE of 3oz. If you eat 3oz of soluble fiber, then drink 1 lb of water, you'll temporarily gain 1lb as the fiber will absorb it. If you take in 1500 calories of sugar and then burn 1500 calories in exercise, you don't always maintain the same weight. 1500 calories of sugar will be retained differently than 1500 calories of protein. Calories are a unit of energy, so the calories in/out scenario would only work if your body metabolized all foods the same way.
Calories are not the only factor like they used to think. It's what TYPE of calories.
I personally lost 50 lbs at 44 by not eating. Seriously. I would eat sometimes, but it's amazing what happens if you only eat when you need to. I am on a fiber supplement (cholesterol, family history of colon cancer, etc). Breakfast was usually some Metamucil and coffee. Not mixed together. Do not recommend. I would get a little hungry around 2pm so I would have something that was dense in things my body needs; tuna salad and some carrots, or a chicken breast and broccoli. I would sometimes go to bed not feeling hungry, although a handful of peanuts is common for me to grab in the evening.
I also did some very light jogging (bad knees) and some very light weight training (bad back) but mostly for heart health, not as a weight loss plan.
Fill your house with healthy stuff that has what your body needs. Only eat it when your body says you need it. I don't mean, "it's 1pm, I should eat before I go to work so I don't get hungry," I mean, "I'll carry this Clif bar IF I get hungry."
I thought the first month would be hell, but it really wasn't. People in first world countries eat on a schedule whether we're hungry or not. Once I tossed that idea in the trash I lost 50 lbs in about 8 months. Yes, you'll plateau and get discouraged, but it always kicks back in. Make your body eat itself.
In my case, I gained back 20 lbs but it was because I failed the plan. The plan didn't fail me. I started eating like an American again. My fault.
