Does drinking water before meals really help you lose weight?

A stream of water pouring into and splashing around a tall glass with ice against blue background; concept is water and weight

For those who’ve ever tried to lose extra weight, you’ve got in all probability gotten this recommendation: drink extra water. Or maybe it was extra particular: drink a full glass of water earlier than every meal.

The second suggestion looks as if an inexpensive concept, proper? For those who fill your abdomen with water earlier than consuming, you may really feel fuller and cease consuming sooner. However did that be just right for you? Would ingesting extra water all through the day work? Why do individuals say ingesting water may also help with weight reduction — and what does the proof present?

Stretching nerves, burning energy, and thirst versus starvation

Three high theories are:

Really feel full, eat much less. As famous, filling up on water earlier than meals has intuitive enchantment. Your abdomen has nerves that sense stretch and ship indicators to the mind that it is time to cease consuming. Presumably, ingesting earlier than a meal might ship comparable indicators.

  • The proof: Some small, short-term research help this concept. For instance, older examine topics who drank a full glass of water earlier than meals tended to eat lower than those that did not. One other examine discovered that folks following a low-calorie food regimen who drank additional water earlier than meals had much less urge for food and extra weight reduction over 12 weeks than these on the same food regimen with out the additional water. However neither examine assessed the affect of ingesting additional water on long-term weight reduction.

Burning off energy. The water we drink should be heated as much as physique temperature, a course of requiring the physique to expend power. The power spent on this — referred to as thermogenesis — might offset energy from meals.

  • The proof: Although older research supplied some help for this clarification, newer research discovered no proof that ingesting water burned off many energy. That calls the thermogenesis clarification for water-induced weight reduction into query.

You are not hungry, you are thirsty. This clarification means that generally we head to the kitchen for one thing to eat once we’re really thirsty relatively than hungry. If that is the case, ingesting calorie-free water can save us from consuming pointless energy — and that would promote weight reduction.

  • The proof: The regulation of thirst and starvation is advanced and varies over an individual’s lifespan. For instance, thirst could also be dulled in older adults. However I might discover no convincing research in people supporting the notion that people who find themselves thirsty misread the feeling for starvation, or that that is why ingesting water would possibly assist with weight reduction.

Train booster, no-cal substitution, and burning fats calls for water

Being well-hydrated improves train capability and thus weight reduction. Muscle fatigue, cramping, and warmth exhaustion can all be introduced on by dehydration. That is why additional hydration earlier than train could also be beneficial, particularly for elite athletes exercising in heat environments.

  • The proof: For most individuals, hydrating earlier than workouts appears pointless, and I might discover no research particularly inspecting the function of hydration to exercise-related weight reduction.

Swapping out excessive calorie drinks with water. Sure, in the event you often drink high-calorie drinks (equivalent to sweetened sodas, fruit juice, or alcohol), persistently changing them with water can help weight reduction over time.

  • The proof: A dramatic discount in calorie consumption by substituting water for higher-calorie drinks might actually result in long-term weight reduction. Whereas it is laborious to design a examine to show this, oblique proof suggests a hyperlink between substituting water for high-cal drinks and weight reduction. Even so, simply as calorie-restricting diets are laborious to stay with over the long run, following a water-only plan could also be simpler mentioned than executed.

Burning fats requires water. Dehydration impairs the physique’s capacity to interrupt down fats for gas. So, maybe ingesting extra water will encourage fats breakdown and, finally, weight reduction.

  • The proof: Although some animal research help the concept, I might discover no compelling proof from human research that ingesting additional water helps burn fats as a method to lose extra weight.

The underside line

So, do you have to bump up hydration by ingesting water earlier than or throughout meals, and even at different instances in the course of the day?

Some proof does recommend this would possibly help weight reduction, no less than for some individuals. However these research are principally small or short-term, or primarily based on animal knowledge. Even constructive research solely discovered modest advantages.

That mentioned, in the event you assume it is working for you, there’s little draw back to ingesting a bit extra water, apart from the problem of making an attempt to drink in the event you aren’t notably thirsty. My take? Although loads of individuals advocate this strategy, it appears primarily based on a concept that does not maintain water.
