Answer:

Vitamin D comes in several forms, each with different roles. For example, vitamin D3 helps maintain strong bone structure, stable neuromuscular function, participates in energy metabolism, and regulates immunity, mood, and cognition.

When you gain weight, your body accumulates fat, and since vitamin D is fat-soluble, it tends to be diluted by this fat. This lowers the concentration of circulating vitamin D in the blood, leaving the body without enough to perform its physiological functions.

Obese individuals often tend to engage in less outdoor activity or wear more covering clothing, reducing the skin's ability to synthesize vitamin D from sunlight exposure. Hormonal changes due to obesity impair enzymes involved in vitamin D metabolism, exacerbating the deficiency.

You should supplement with vitamin D as directed by your healthcare professional to protect overall health and facilitate weight loss. Adequate vitamin D levels optimize energy metabolism and enhance the effectiveness of exercise, thereby supporting weight loss and stable weight management.

You can utilize sunlight by sunbathing for 15-20 minutes daily between 9 a.m. and 3 p.m. to allow your body to naturally synthesize the necessary vitamin D. Dietary sources of vitamin D include salmon, sardines, cod liver oil, egg yolks, mushrooms, and milk. Those with severe deficiencies or living in areas with limited sunlight can take supplements as prescribed and advised by a healthcare professional.

For sustainable weight loss, you should adopt a healthy lifestyle and a balanced, nutritious diet. Prioritize natural, minimally processed foods rich in protein, green vegetables, and whole grains. Maintain a regular exercise routine of at least 30 minutes daily, 5 days a week. A relaxed mind, sufficient sleep, and stress management optimize metabolism and support weight loss.
