Crash diet courses and intense restrictions are now passé! In 2025, weight loss is being redefined with smarter, science-backed methods that do not rely on traditional dieting. Many people are now focusing on sustainable weight loss strategies, ones that improve metabolism, hormone function, and lifestyle balance as well. What we need to understand is that exercising can only do so much; lifestyle changes and dietary additions also aid in weight loss.Dr. Vassily Eliopoulos (Dr. Vass), MD, who is a well-known longevity doctor and co-founder of Longevity Health clinic, captioned his Instagram post and said, “You have been lied to about weight loss. It is not just about calories in, calories out.”Let us see what he has to say about these 5 techniques of weight loss without dieting.

Peptides: Metabolism’s secret weapon

A peptide is a small chain of amino acids that makes up proteins in the body. They are also a new tool doctors are prescribing to help people lose weight. Some peptides, such as Lpamorelin and CJC-1295, don’t just help us burn fat, they also optimise our growth hormone levels and boost cellular repair. Apart from aiding in weight loss, they also help improve our sleep quality, increase our metabolic rate, and aid in faster recovery.

Find and fix hidden vitamin deficiencies

Vitamins are essential building blocks of our body and a lack of certain vitamins means sluggish metabolism. Low vitamins such as magnesium, B vitamins, and Vitamin D are especially linked to challenges in weight loss. All the mentioned vitamins boost metabolism by supporting energy production, hormone balance and insulin sensitivity, which are key factors that help our bodies to burn more fat and aid in faster weight loss.

Hybrid training: Strength + cardio

Combining strength training with cardio is one of the most effective ways to lose weight as stated by Dr. Vass. It burns calories, builds lean muscle and keeps the metabolism active by helping one shed fat. According to Dr. Vass, aim for a minimum of 3 hours a week of cardio to elevate heart rate and 2 hours per week of progressive weight training.

One size doesn’t fit all, follow a personalised nutrition plan

The Mediterranean diet, as stated by Dr. Vass, is a great way to lose weight faster. A Mediterranean diet consists of foods that are rich in healthy fats, fiber and antioxidants. It supports healthy metabolism, reduces inflammation in the body and helps regulate hunger. One can always start with veggies, fatty fish and complex carbs (brown rice, oats, chickpeas etc).

Reset the body’s metabolism with fasting

Fasting boosts autophagy in the body, which helps get rid of the body’s cellular waste. Not only cellular repair but it also improves metabolic efficiency, reduces bodily inflammation and enhances fat-burning over time.In all, what one should remember is that true weight loss is not just about diet or exercise, it is a complete lifestyle shift.See more: Weight Loss Tips to Lose Inches of Stubborn Belly Fat in a Healthy Way
