Everyday eating: fiber, meal timing, the freezer, eggs and walking after meals

Small everyday decisions add up over the weeks: how much fiber to eat, how many meals to have, what to buy frozen, how many eggs fit and what to do right after eating. This guide brings together what studies show about each one, with practical suggestions to try.

Fiber and constipation: how to increase it gradually

In a review of 16 studies with 1,251 adults with constipation, 66% of those who used fiber supplements improved, versus 41% of comparison groups. Improvement appeared with more than 10 g of fiber per day and 4 weeks or more, and psyllium and pectin had the best results [1]. Water may add to this: with about 25 g of fiber per day, those who drank about 2 liters of fluid improved more than those who drank 1 liter [2]. Among foods, there is some evidence for fruit, especially kiwi, and rye bread, from few studies [3].

A sample day: 30 g of oats, 1 banana, 100 g of beans, 100 g of brown rice and 1 guava add up to about 22 g of fiber. As a general health reference, the best outcomes were associated with 25 g to 29 g per day [4]. Add one food at a time, with a few days in between, since fiber increases gas, drink water through the day and keep it up for at least 4 weeks before drawing conclusions.

4 daily templates, with 2 to 5 meals

The number of meals does not switch your body off or speed it up. In 15 adults who ate the same amount in 3 or 6 meals, daily energy expenditure was about 2,080 and 2,055 kcal, with no difference, and hunger was higher with 6 meals [5]. With 14 meals, resting expenditure was slightly lower and hunger higher [6]. Over 8 weeks of calorie restriction, 3 meals or 3 meals plus 3 snacks gave the same result [7], and reviews found no difference in daily expenditure [8][9].

Choose the template closest to the week you already have and test it for 2 weeks. If a meeting runs late, eat when you can: a missed time does not undo the day.

Freezer guide: what to keep and what to check on the label

In 8 fruits and vegetables measured fresh, stored for 5 days in the fridge and frozen, most comparisons of vitamin C, provitamin A and folate showed no difference, and when there was one, frozen beat stored fresh more often [10]. In another study, vitamin C tied in 5 of 8 foods and was higher in frozen produce in the other 3; the exception was beta-carotene, lower in frozen peas and carrots [11]. Both studies were funded in partnership with the frozen food industry and measured the food, not the health of people eating it.

• Worth keeping in the freezer: broccoli, cauliflower, green beans, peas, spinach, corn, strawberries and blueberries.
• On the label, ideally only the food itself; sugar in fruit and salt or sauce in vegetables change what you are buying.
• Buy fresh what you will eat in the next few days and rely on frozen for the end of the week.

Eggs and cholesterol: 6 questions for your appointment

An analysis of 1.7 million people found no association between each extra egg per day and more heart disease [12]. In 29,615 adults followed for 17 years, half an egg more per day was associated with 6% higher risk, an association that disappeared after accounting for total dietary cholesterol [13]. In controlled trials, LDL was on average 5.55 mg/dL higher with eggs, and HDL 2.13 mg/dL higher [14]. In 40 adults with high cholesterol, 2 eggs a day for 6 weeks did not worsen their lab results [15]. The American Heart Association advises looking at the overall eating pattern and urges caution for people with abnormal cholesterol [16].

• What is my LDL target, considering my age and personal and family history?
• Could my high cholesterol have a genetic cause?
• In my situation, how many eggs per week fit? Does that change if I have diabetes?
• What weighs more on my lab results today: eggs or the rest of my diet?
• If I change my diet, when should I repeat the test?
• Do I or will I take cholesterol medication? What changes in my diet then?

Seven breakfasts to rotate: boiled egg with whole-grain bread and fruit; omelet with tomato and spinach; scrambled eggs with vegetables and tapioca; poached egg on whole-grain bread with avocado; oats with yogurt, fruit and nuts; whole-grain bread with chickpea spread; yogurt with banana, oats and seeds.

Walking after meals: 5 ways to fit it in

In 41 adults with type 2 diabetes, walking 10 minutes after each main meal reduced the rise in blood sugar over the next 3 hours by 12%, and by 22% after dinner, compared with 30 minutes at once [17]. Breaking up sitting with 2-minute walks every 20 minutes reduced the rise by about 30% [18], and trials favor exercise after meals, with a high risk of bias [19]. Standing already helped, and walking helped more [20]; older adults also had lower blood sugar after dinner [21]. The exact timing is not settled: in healthy adults, the effect appeared when starting 45 minutes after the start of the meal [22].

• At work: get coffee from across the block, or have lunch a little farther away and walk back.
• In the rain: walk the hallways, take a flight of stairs slowly or simply stand.
• With children: go together to the corner, the playground or the bakery.
• Short on time: 5 minutes already gets you out of the chair.
• In the evening: leave your shoes by the door and go right after dinner, on a well-lit route.
