A 3-month pre-contest energy-restricted diet combined with an 8-week resistance training taper results in significant body mass loss (10.3%) but preserves or transiently increases maximal strength (isometric knee extension) prior to competition.
If you are cutting weight for a competition, expect your strength to fluctuate. In this case, strength peaked early in the cut and declined as the event approached, but returned to baseline after the event. Focus on maintaining protein intake (1.9-2.2 g/kg) and using a taper (reducing volume) in the final 10 days to manage fatigue while preserving strength.
The athlete undertook a 3-month pre-contest preparatory period that included an extreme to sufficiently energy-restricted diet intended to reduce body mass... The athlete’s isometric knee extension strength rose sharply during the initial month of the pre-competition phase (336.4 Nm), followed by consistent declines... eventually returning close to baseline values 2 months post-competition.

- Bariatric surgery (VSG and RYGB) is the most effective and sustainable treatment for obesity, producing marked and sustained weight loss that non-surgical interventions cannot match.Strong
- Severely protein-deficient diets (2–3% energy) induce lean body mass loss and metabolic imbalance, whereas adequate protein intake (0.66 g/kg/d minimum) is a prerequisite for maintaining muscle, bone, and physiological function.Strong
- For patients with Class III obesity (BMI >39.9 kg/m2), metabolic bariatric surgery (MBS) is significantly more effective than any currently approved medication, with BilioPancreatic Diversion (BPD) showing the highest estimated weight loss.Strong
