How To Time Your Meals For Optimal Weight Loss

You’ve probably heard that eating before bed isn’t wise, especially if you’re trying to lose weight. But are there other times of the day when eating may derail your weight loss goals? Could it be that when you eat may be just as important as what you eat?

Science Shows When We Eat May Be Important

Research is gradually learning more about the connection between the body’s natural biorhythms and weight gain. When we don’t get enough sleep, for example, we trigger reactions in the brain that confuse the signals of tiredeness and hunger and may increase our cravings for sugar and starchy foods. A recent study published in the American Journal of Clinical Nutrition, for example, found that sleep loss can boost hunger and slow the rate of calorie burn, promoting weight gain, while getting plenty of sleep can prevent it.

Animal studies have also shown that messing with sleep and the body’s internal clock causes mice to eat at the wrong times and gain weight. A more recent study in humans published in Obesity found similar results. Late sleepers went to bed at 3:45 a.m., woke up at 10:45 a.m., ate breakfast at noon, lunch at 2:30 p.m., dinner at 8:15 p.m., and their final meal at 10:00 p.m. Normal sleepers went to bed by 12:30 a.m., woke up about 8:00 a.m., had breakfast by 9:00 a.m., lunch at 1:00 p.m., dinner at 7:00 p.m., and their last snack about 8:30 p.m.

The “night owls” got less sleep overall, ate more fast food, drank more soda, and ate fewer fruits and vegetables. Overall, they ate about the same calories per day as the normal sleepers, but they ate a larger proportion of those later in the day–at dinner or after 8:00 p.m. Researchers found that calories consumed after 8:00 p.m. were most strongly associated with weight gain, and concluded that it’s not only the quality of your diet that matters, but the time of day you’re eating.

“The study suggests regulating the timing of eating and sleep could improve the effectiveness of weight management programs,” said lead study author Dr. Phyllis Lee.

Bright Lights May Mean Big Pounds

An earlier study found something else that may be interrupting the body’s internal clock and leading to late-night eating–light. In animal studies, mice exposed to light at night gained a whopping 50 percent more weight than mice whose nights were truly dark. That nighttime light encouraged the mice to eat at times when they would normally be sleeping. When researchers restricted meals to the times when the mice normally ate, regardless of light exposure, the mice didn’t gain weight.

Researchers concluded again that the timing of meals could make a difference in weight gain, as well as reduced light exposure at night.

Re-Set Your Eating Clock

So how do you maximize the timing of your meals to lose weight? Below are several tips to try.

‘Have your dinner before 8:00 p.m.: Study results show that eating after 8:00 p.m. is associated with weight gain. If you need a late-night snack, try a small glass of milk or a cup of decaffeinated or herbal tea.
Eat a healthy breakfast: Though eating more calories at breakfast might encourage eating more calories throughout the day, avoiding breakfast completely also encourages weight gain. According to data from the National Weight Control Registry, eating a balanced, healthy breakfast is a daily habit that leads to successful long-term weight loss.

Consider a larger lunch and smaller dinner: Depending on your daily schedule, you may want to consider eating more at lunch, and a little less at dinner. The body’s ability to digest meals is best at peak energy times, which occur around noon to 3:00 p.m. In fact, many people experience nighttime indigestion and heartburn because they eat their biggest meal around 6:30 or 7:00 p.m. Move your dinner time up an hour, cut down on nighttime calories, and if a big lunch leaves you sleepy for afternoon meetings, consider splitting your lunch into two servings–noon, and mid-afternoon.

Eat about 45 minutes after exercise: Eating before your workout may make you uncomfortable. Eating about 45 minutes afterwards, however, reduces the amount of energy that will be stored as fat, as the body uses the food to replenish low glycogen stores caused by exercising.
Avoid starchy carbs three hours before bedtime: Foods like breads, pastas, rice, potatoes, cakes and cookies will boost your insulin levels before bed, which can encourage weight gain. Instead, eat lean proteins, veggies and fruits at your last meal.
