Overweight Women Lose More Weight While Dieting If Main Meal Is Lunch Instead of Dinner

Breakfast of kings?

Breakfast of kings?

They say that to lose excess weight, you should eat breakfast like a king, lunch like a prince, and dinner like a pauper.

A recent study tested whether weight loss in dieting women was more effective by making lunch rather than dinner (evening meal) the main meal of the day. Over the course of 12 weeks, dieters making lunch their main meal lost 4 lb (2 kg) more than the other group.

From the abstract:

“Background: The association between the time of nutrient intake and health has been described in a few studies. To our knowledge, no study has evaluated the relation between high energy intakes at lunch compared with at dinner on weight loss in overweight and obese subjects.

Objective: We compared the effect of high energy intake at lunch with that at dinner on weight loss and cardiometabolic risk factors in women during a weight-loss program.Design: Overweight and obese women [n = 80; body mass index (BMI; in kg/m2): 27–35; age: 18–45 y] were asked to eat either a main meal at lunch (LM) or a main meal at dinner (DM) for 12 wk while in a weight-loss program.

Conclusions: The consumption of higher energy intake at lunch compared with at dinner may result in favorable changes in weight loss in overweight and obese women after a weight-loss program of 12 wk. The consumption may also offer clinical benefits to improve insulin resistance.”

I don’t have the full text of the research report, so I don’t know what kind of diet the women were on. The researchers seem to be based in both Iran and Great Britain. I don’t know the nationality of the women participating. The metabolism of Iranians may be different from Brits.

“Low Sugar Diet,” Whatever That Is, Is the Most Popular in U.K. This Year

…according to an article at TLE. The second most popular diet plan is carbohydrate restriction (low-carb diet). Of course, sugars are carbohydrates.

The most frustrating sentence I read was that “…less than 10% of respondents stated that they intend to make long term changes to their eating habits.”

People, if you go back to your old way of eating, you’re going to gain the weight back. Duh!

That’s why there’s an endless array of new diets.

Obese and Have Psoriasis? Weight Loss Reduces Severity

Sure, it’s a small research study and I only have the abstract.

Anyway, a reduced-calorie diet led to loss of 15 kg (33 lb) over 16 weeks. Over the next 48 weeks, dieters only regained 5 kg (11 lb). (But, hey. Diets don’t work, right?)

It’s possible the specific diet itself lead to the psoriasis improvement, but the researchers don’t make that claim in the abstract. They credit the long-term weight loss:

“Long-term weight loss in patients with psoriasis has long-lasting positive effects on the severity of psoriasis.”

Band Gastric Bypass Surgery

Self-harm emergencies rose by 50% after gastric bypass surgery in the Canadians in this study.

Folks on my diets lose weight without an increase in suicide risk, as far as I know. Click on my name for the diets.

Are Diet Beverages OK When You’re Trying to Lose Weight?

Overweight and obese women who habitually drank diet beverages lost more weight if they substituted water for the diet beverage. Over the course of 24 weeks on a reduced calorie diet, the water drinkers lost an extra 1.2 kg (2.6 lb) compared to those who continued their diet beverage habit.

Furthermore, the researchers found that the water drinkers had healthier values on insulin levels, HOMA-IR (a measure of insulin resistance), and after-meal blood sugar levels.

It was a small study with only about 30 in each experimental group. Whether similar results would be seen in men is unknown to me.

In the past, I’ve advised dieters it’s OK to drink diet drinks in moderation while trying to weight. I may have to revise my recommendations. On the other hand, if diet drinks help keep you happy and on a successful weight-loss journey, they may be helpful. The diet beverage consumers still lost 7.6 kg (16.7 lb) compared with 8.8 kg (19.4 lb) in the abstainers. But diets don’t work, right?

PS: I haven’t read the full text of the article; just the abstract.

PPS: Steven Novella at Science-Based Medicine blog concludes that low energy sweeteners probably help with weight control.

What Really Was William Banting’s Diet?

Banting thought salmon was too fatty

Banting eschewed salmon (too fatty?)

I’ve been reading about Banting’s diet for at least five years. Thanks to Tim Noakes in South Africa, it’s seeing a mini-surge in popularity. William Banting published his Letter on Corpulence in 1863. Eating like him to lose weight is sometimes referred to as “Banting.” It’s one form of a low-carb diet and considered a precursor to the Atkins diet.

Form your own opinion of what William Banting may have eaten by reading these:

In terms of macronutrient calories, here’s my rough back-of-the-envelope synthesis of Banting’s diet:

  • 20–25% carbohydrate
  • 25% protein
  • 20–25% fat
  • 25% alcohol
  • 1800–2000 total calories

For the 200 lb (91 kg) man that Banting was, 2000 calories would almost certainly have been a calorie-restricted diet. Leigh estimated he was eating at least 2800 cals/day at baseline before losing weight. I don’t doubt that.

In summary, Banting drank a lot of alcohol (even more than on the Ketogenic Mediterranean Diet), and ate fairly low-fat, moderately carb-restricted, and relatively high protein. In other words: low cal, low carb, low fat, high protein, high alcohol.

His weight loss, assuming it wasn’t a hoax, came from calorie restriction. Something about that combination of macronutrients apparently allowed him to stick with the program and maintain a 50-lb weight loss. Protein is particularly satiating. Your mileage may vary.

I’m concerned that 25% of calories from alcohol would displace more healthful micronutrients.

PS: William Banting was a distant relative of Frederick Banting, the co-discoverer of insulin in 1921.

Expert Weight-Loss Tips

1.  Record-keeping is often the key to success.

2.  Accountability is another key to success. Consider documenting your program and progress on a free website such as FitDay, SparkPeople, 3FatChicks, Calorie Count (http://caloriecount.about.com), or others. Consider blogging about your adventure on a free platform such as WordPress or Blogger. Such a public commitment may be just what you need to keep you motivated.

3.  Do you have a friend or spouse who wants to lose weight? Start the same program at the same time and support each other. That’s built-in accountability.

4.  If you tend to over-eat, floss and brush your teeth after you’re full. You’ll be less likely to go back for more anytime soon.

5.  Eat at least two or three meals daily. Skipping meals may lead to uncontrollable overeating later on. On the other hand, ignore the diet gurus who say you must eat every two or three hours. That’s codswallop.

6.  Eat meals at a leisurely pace, chewing and enjoying each bite thoroughly before swallowing.

7.  Plan to give yourself a specific reward for every 10 pounds (4.5 kg) of weight lost. You know what you like. Consider a weekend get-away, a trip to the beauty salon, jewelry, an evening at the theater, a professional massage, home entertainment equipment, new clothes, etc.

8.  Carefully consider when would be a good time to start your new lifestyle. It should be a period of low or usual stress. Bad times would be Thanksgiving day, Christmas/New Years’ holiday, the first day of a Caribbean cruise, and during a divorce.

9.  If you know you’ve eaten enough at a meal to satisfy your nutritional requirements yet you still feel hungry, drink a large glass of water and wait a while.

10  Limit television to a maximum of a few hours a day.

11.  Maintain a consistent eating pattern throughout the week and year.

12.  Eat breakfast routinely.

13.  Control emotional eating.

14.  Weigh frequently: daily during active weight-loss efforts and during the first two months of your maintenance-of-weight-loss phase. After that, cut back to weekly weights if you want. Daily weights will remind you how hard you worked to achieve your goal.

15.  Be aware that you might regain five or 10 pounds (2-4 kg) of fat now and then. You probably will. Don’t freak out. It’s human nature. You’re not a failure; you’re human. But draw the line and get back on the old weight-loss program for one or two months. Analyze and learn from the episode. Why did it happen? Slipping back into your old ways? Slacking off on exercise? Too many special occasion feasts or cheat days? Allowing junk food or non-essential carbs back into the house?

16.  Learn which food item is your nemesis—the food that consistently torpedoes your resolve to eat right. For example, mine is anything sweet. Remember an old ad campaign for a potato chip: “Betcha can’t eat just one!”? Well, I can’t eat just one cookie. So I don’t get started. I might eat one if it’s the last one available. Or I satisfy my sweet craving with a diet soda, small piece of dark chocolate, or sugar-free gelatin. Just as a recovering alcoholic can’t drink any alcohol, perhaps you should totally abstain from…? You know your own personal gastronomic Achilles heel. Or heels. Experiment with various strategies for vanquishing your nemesis.

17.  If you’re not losing excess weight as expected (about a pound or half a kilogram per week), you may benefit from eating just two meals a day. This will often turn on your cellular weight-loss machinery even when total calorie consumption doesn’t seem much less than usual. The two meals to eat would be breakfast and a mid-afternoon meal (call it what you wish). The key is to not eat within six hours of bedtime. Of course, this trick could cause dangerous hypoglycemia if you’re taking drugs with potential to cause low blood sugars, like insulin and sulfonylureas. If you take drugs for diabetes, talk to your dietitian or physician before instituting a semi-radical diet change like this.

18.  One of the bloggers I follow is James Fell. He says, “If you want to lose weight you need to cook. Period.” James blogs at http://www.sixpackabs.com, with a focus on exercise and fitness.

19.  Regular exercise is much more important for prevention of weight regain rather than for actually losing weight.
