Background on the Issue

While December is often associated with celebration and togetherness, health experts caution that it also brings an increase in cardiovascular risks and weight gain. Cardiologists and bariatricians have noted that December records one of the largest spikes in cardiac emergencies throughout the year, with mortality rates potentially rising by 3% to 5% compared to other months.

Reasons Behind the Increase

Several factors contribute to this rise, including abundant meals, excessive salt and fat intake, increased alcohol consumption, accumulated stress, and drastic temperature changes. For individuals with hypertension, diabetes, obesity, or family history, these elements compound the risk of cardiovascular issues.

Weight Gain During the Holiday Season

Dr. David Montalvo Castro, a bariatrician, highlights that December is particularly critical due to the significant increase in caloric intake. Even small weight gains can take weeks of discipline to reverse.

  • Adult Men: 2 to 3 kg
  • Adult Women: around 4 kg
  • Children: approximately 2 kg

For those already dealing with obesity, the weight gain can double:

  • Adult Men: up to 4 kg
  • Adult Women: 6 kg or more
  • Children: 3 to 4 kg

Dr. Montalvo Castro emphasizes that these increases should not be underestimated, as losing 5 to 6 kg is manageable, but regaining 12 to 15 kg or more can take over two months of strict dietary control.

Medication Interruptions and Risks

It’s common for patients managing hypertension, diabetes, dyslipidemias, or other complications to suspend medication during holiday celebrations in favor of alcohol consumption. This decision increases the risk of experiencing cardiovascular or metabolic events, such as hypertensive crises or sudden spikes in blood glucose levels requiring urgent medical attention.

Recommendations for a Healthier December

While exercise helps maintain stable weight and blood pressure, diet remains the most influential factor. Here are some recommendations from Dr. Montalvo Castro:

  • Eat plenty of vegetables and low-calorie salads.
  • Stay hydrated with natural water and avoid sugary drinks.
  • Choose steamed, baked, or grilled white meats accompanied by vegetables.
  • Opt for seasonal fruits.
  • Avoid prolonged fasting.
  • Reduce refined grains, fats, and sugars.
  • Control portion sizes and avoid snacking between meals.
  • Eat slowly and savor your food.
  • Maintain regular physical activity.
