Humbly- I actually consider myself an expert on weight-loss. I just spent the last 2 months to successfully get down to my college underclass weight. Guarantee this will work for anyone. I researched, and did it successfully:
Alter your philosophy:
Speed metabolism. Calorie counting or "losing" (or that approach) is not the best way or the way to think about it.
How to speed metabolism:
1) More & smaller meals. (Nothing ground-breaking here). Keep some food with you always, to nibble if at all hungry. I keep unsalted nuts. If the body goes long w/o food, then it "keeps" its calories and learns not to burn them- as it does not know when the next meal is coming. But if always nibbling or eating frequent meals, then it trusts food is always coming, and burns away.
2) Foods that speed the metabolism. Do a google search- but Oatmeal & Yogurt are a couple. Clean foods are obvious ones, too. Protein with each meal- not like those large powder quantities, that body-builders use. But like yogurt (lots of protein). Protein takes much more body energy to burn, and speeds the metabolism. So include it with each meal to get the body burning. Biotin vitamin as well. It actually has a chemical that is necessary for the metabolism process. A "wierd" thing is hot peppers. They speed the metabolism for ~20 mins. I resisted, because it didn't seem healthy. But Cayenne Peppers are super healthy for the blood pressure & for a low cholesterol. So before a meal, I take a swig of Cayenne Pepper sauce. Weird- but it's healthy & works.
3) 1 min of calisthenics before/after each meal. Exercise keeps the metabolism fast for a while- so your body is burning away that meal.
4) If you do pushups or lift weights in addition to running, then try doing them at an "inactive" period. In other words, if your finished exercising for the day @ 4:00pm.. then that's another 5-6 hours of inactivity. So maybe do some pushups or lifting around 8:00pm. It doesn't have to be a hero's workout. But frequent exercise helps keep that metabolism going.
5) Eat not to stuff yourself, but to cure hunger.
6) Never let you body feel "void" of food. That's just fool's gold for losing weight. It helps for tomorrow but not next week. At the same time, this doesn't mean 2nd's and 3rd's.
7) Patience. For me, it took about 2.5 weeks to notice things. And as we know, correct weight-loss is a slow, steady loss. But the method above can lose a person plenty, while they feel stronger.
8) Final note: Michael Phelps reportedly will eat 12,000 calories/day- but his body's a furnace. This is pretty high-end, but it's what I'm getting at. I'm eating more lately, but weighing less, and am lifting as well as before losing. It works.
