Is it true that weight gain comes from eating foods with the wrong pH?

Shari Portnoy

This is an interesting question and not sure why it is addressed? PH means percent Hydrogen. Food high in pH are less acidic than foods low in pH. This doesn't affect weight loss. Weight loss is affected by how many calories you take in vs. how many you release. It is a balance game.

This statement is misleading. Instead of worrying about the pH of the food you eat, eat foods that promote health. These include beans, fresh produce, fruit, whole grains, healthy fats and lean protein. The pH of your urine is more important than the pH of your food. If you eat a plant based diet, your body should be more alkaline.

Weight gain comes from consuming more energy than is needed by the body. The density calories have a strong impact on weight gain, but the pH of food has none. This misconception began because of the recommendation to consume copious amounts of fruits and vegetables.

No, it is not true. The pH of food has nothing to do with gaining weight. Weight gain is multifactorial. Factors affecting someone's weight gain can include overeating, large portion sizes, lack of activity, medications, hormonal, and lack of good sleep.  
pH is a measure of the acidity or alkalinity of a solution. Different compartments in your body have a different pH, and very often the pH is associated with what occurs in that department of your body. For example, your stomach has a very acidic pH and this helps to prepare proteins (denature) for digestion. This low pH also stops carbohydrate digestion in the stomach, and then the higher pH of the small intestine promotes the resumption of carbohydrate. These various pH values are very carefully protected. Eating certain foods can not disrupt this carefully protected homeostasis – our ability to physiologically regulate our inner environment to ensure its stability in response to fluctuations in the outside environment.
