How do you eat 6 meals a day with 1500 calories/day?

Take a look at this.

They advocate 3 meals and 2 snacks. It works for me. I'm aiming for 1600 calories, and it's working OK for me. I don't always use their recipes, but the schedule and the general division of calories is pretty good.

I eat 6 meals at 1300 cals a day

Breakfast: 250kcal
Snack 100kcal
Lunch: 250kcal
Snack: 150kcal
Dinner: 350kcal
Supper: 200kcal

Voila!

Do what works for you. There is no evidence that five or more meals makes any difference to weight loss. Ditto to eating breakfast or not eating before bed.

Get good nutritious food, keep your macros in line and you can eat when you want.

I always shoot for a carb and protein at each 'meal/snack' whatever you want to call it

about 250 a meal/snack

apple with peanut butter
chicken with veggies
cottage cheese with peaches
protein bar with a fruit
egg with toast

What I do is use most of my calories for my three main meals, then leave a few for snacks between.

For example

Breakfast 300
Lunch 400
Supper 500

Then your three snacks for 100 cal each.

great luck to you

My non-cycle-commute-day menu:

Breakfast: 1/2 cup oatmeal, 1 fried egg: 150-ish calories.
Snack #1 at 10:30 - half a wrap consisting of 1 wheat tortilla, 1 slice American cheese, and some turkey lunch meat: 120 calories
Snack #2 at 11:30 - other half of wrap: 120 calories
Snack #3 (post-workout if I do one): Banana, handful of almonds and walnuts: ~340 calories
Snack #4 late afternoon: Big bag o'fresh veggies and an apple: 90 calories

I'm on a 1450-calorie diet, and even if I don't work out that day I have about 600-650 calories to work with for supper on a normal day. If I want a larger supper, I work out more.

EDIT: Clarification - The continual "slow drip" of calories keeps me from feeling particularly hungry at any specific time during the day, and has helped me curb cravings and avoid temptations. This is a PSYCHOLOGICAL tool I am using, there is no physiological benefit to doing this. However, it works very well for me and has helped me lose weight with little to no hunger/cravings.

Barring any underlying medical condition, there's no dietetic or metabolic reason you NEED to eat more often. You could take this entire menu and turn it in to a simple "egg-and-oatmeal for brekkies, everything else at lunchtime" day and your metabolism would work exactly the same (except maybe if you have a heavy workout - you want to make sure you do a little fueling before and after that in my experience). Hell, you could probably take all your food for the day and scarf it at 8AM and go 23 1/2 hours without food with almost no change in anything.

I guess technically I eat 6 meals a day-although it feels more like I just graze. I kind of have 2 breakfasts (approx 200 cal each), then I have lunch (around 300 calories). Then I have a snack-another 200 calories (by "snack" this could be anything from yogurt & string cheese to a whole "meal" like a salad or sandwich or soup-but whatever it is it's generally around 200 calories). Then dinner rolls around and I have another 400 calories (sometimes 500-kind of depends). I then have another 100-200 calories before bed. So I eat 6 times a day-a good volume of food each time-but it really feels like I am eating every couple of hours (I guess I pretty much am).

Take a look at my diary. I stay around 1400 cals a day and I eat about 6 times a day. A typical day looks like this:

Breakfast: 1 egg, 2 slices turkey bacon, 1 slice cheese, small apple or some other fruit (today was cherries!)

AM Snack: pistachios, 1/4 of a baked or grilled chicken breast

Lunch: Lean meat like chicken or fish with some sort of veggie (my favs are brussell sprouts or spinach)

PM Snack: baby carrots, sometimes hummus, and 1/4 of a baked or grilled chicken breast

PM Snack #2 (pre-workout): banana

Post workout: Protein shake (usually a Muscle Milk Light or EAS Carb advantage)

Dinner: Lean meat, veggies

And often, I still have calories left for a glass of red wine

Just remember, you can eat like a TON of veggies for very little calories, so eating lots of veggies and 2-3 servings of fruit a day will really help to keep you full for a small amount of calories. You'll also notice I eat zero bread/rice/pasta (it upsets my stomach, just doesn't agree with my body) and tons of chicken. Lots of protein keeps me full too and gives me plenty of fuel for tough workouts.

I just plan three meals and kind just snack on my lunch when I get hungry in the morning and then bf I go home in afternoon to keep me going when I get home with the kids .... I tend to get too stressed if I overplan meals and then get distracted at work or home and miss them ... I think this has not helped me in the past

I eat 6 at less than 1500 cals., so it's doable. Just get used to smaller "meals" but I make sure they are protein rich so I stay satiated but really I am hardly ever hungry because I eat every three hours. Here's some examples of my meals:

Breakfast - 1/2 a grapefruit with 3 scrambled egg whites with onions and peppers
Mid-morning snack - greek yogurt with a 1/4 cup blueberries and chopped walnuts and a tbsp of honey
Lunch - 4 oz grilled chicken with 1/3 cup wild rice
Afternoon snack -1 slice whole wheat toast with a tbsp peanut butter and half a banana with low-fat chocolate milk
Dinner - 2 cups of herb salad with artichokes and balsamic vinaigrette dressing and 4 oz grilled salmon
Evening Snack - 1 slice low-sodium oven roasted turkey cold cut with 1/4 slice of avocado

I also drink a gallon of water a day which helps to keep me full as well. Good luck!
